Foundamentals of Financial Services Level 2 Quiz Exam Quiz 15

The core concept tested is understanding the interplay between different financial markets and how events in one market can cascade into others, particularly focusing on the impact of sovereign debt downgrades on corporate bond yields and the subsequent effects on equity valuations. The question requires integrating knowledge of capital markets (specifically bond markets and equity markets), risk assessment (credit ratings and risk premiums), and the economic principles of supply and demand. The scenario presents a situation where a sovereign debt downgrade increases the perceived risk of investing in that country, leading to a rise in the risk-free rate used for pricing assets. This increase directly affects the required rate of return for corporate bonds, especially those with lower credit ratings, as investors demand higher compensation for the increased risk. The calculation involves several steps. First, determine the increase in the risk-free rate, which is the difference between the new yield on government bonds and the old yield. Then, assess how this increase affects the required rate of return for the corporate bond, considering its credit rating. Finally, estimate the impact on the company’s equity valuation using the Gordon Growth Model, where the required rate of return is a key input. The Gordon Growth Model states that the price of a stock is equal to the expected dividend per share one year from now, divided by the difference between the required rate of return and the dividend growth rate: \[P = \frac{D_1}{r – g}\], where \(P\) is the stock price, \(D_1\) is the expected dividend per share next year, \(r\) is the required rate of return, and \(g\) is the dividend growth rate. In this scenario, a higher required rate of return, driven by increased risk premiums in the bond market, will decrease the stock price, assuming all other factors remain constant. The question challenges the candidate to apply this model in a context where the change in the required rate of return is indirectly influenced by sovereign debt market dynamics. The correct answer reflects the understanding that an increase in the risk-free rate translates to a higher required rate of return for equities, leading to a lower valuation. The incorrect options present plausible but flawed calculations or misunderstandings of the relationship between bond yields, equity valuations, and the Gordon Growth Model. For example, an incorrect option might assume a direct linear relationship between the increase in the government bond yield and the decrease in the stock price, without considering the dividend growth rate or the initial stock price. Another incorrect option might misinterpret the impact of the downgrade, suggesting it would increase the stock price due to investors seeking safer assets.

The question assesses understanding of the interplay between the money market, capital market, and foreign exchange (FX) market, and how a central bank’s actions can ripple through these interconnected markets. The scenario involves a hypothetical situation where the Bank of England (BoE) unexpectedly intervenes in the money market. The BoE’s purchase of short-term gilts (government bonds) increases the money supply. This action directly impacts short-term interest rates, causing them to fall. Lower short-term rates make holding Sterling less attractive relative to other currencies, leading to a depreciation of Sterling in the FX market. This depreciation, in turn, can influence the capital market. A weaker Sterling makes UK assets cheaper for foreign investors, potentially increasing demand for UK equities and bonds. However, the extent of this impact depends on factors like investor confidence, global economic conditions, and expectations of future interest rate movements. Furthermore, the change in interest rates will affect the yield curve, which is the graphical representation of interest rates across different maturities. The impact on long-term gilt yields is less direct and depends on expectations of future inflation and economic growth. If the market believes the BoE’s action is temporary and won’t lead to sustained inflation, long-term yields might not change significantly or could even fall slightly due to increased demand for safe-haven assets. Conversely, if the market fears that the BoE’s action will lead to higher inflation, long-term yields might rise to compensate investors for the increased inflation risk. The question tests the candidate’s ability to integrate these various market effects and understand the nuances of central bank intervention.

The efficient market hypothesis (EMH) posits that asset prices fully reflect all available information. There are three forms: weak, semi-strong, and strong. The weak form suggests that past price data cannot be used to predict future prices, implying technical analysis is futile. The semi-strong form asserts that all publicly available information is already incorporated into prices, making fundamental analysis ineffective in generating abnormal returns. The strong form states that all information, including private or insider information, is reflected in prices. In this scenario, the fund manager’s ability to consistently outperform the market using insider information directly contradicts the semi-strong form of the EMH. The semi-strong form allows for the possibility of abnormal returns using non-public information. If the market were truly strong-form efficient, even insider information would not provide an edge. The fund manager’s actions are also illegal under UK regulations, specifically the Financial Services Act 2012, which prohibits insider dealing. Using inside information for personal gain is a criminal offense, undermining market integrity and fairness. The act aims to ensure that all market participants have equal access to information and that no one gains an unfair advantage through privileged knowledge. This ensures investor confidence and protects the overall stability of the financial system. The fund manager’s behavior also violates the CISI Code of Conduct, which requires members to act with integrity and avoid conflicts of interest.

The question explores the interconnectedness of money markets and foreign exchange (FX) markets, specifically focusing on the impact of short-term interest rate differentials on currency valuations and investment decisions. A key concept is covered interest parity (CIP), which posits that the forward exchange rate should reflect the interest rate differential between two countries. Deviations from CIP can create arbitrage opportunities. The scenario involves a fund manager assessing the attractiveness of investing in short-term UK Treasury bills (gilts) versus US Treasury bills, considering both the interest rate differential and the FX implications. To determine the optimal investment strategy, the fund manager needs to compare the expected return from the UK investment, adjusted for FX risk, with the return from the US investment. This involves calculating the implied forward exchange rate based on the interest rate differential and comparing it to the market-quoted forward rate. If the market forward rate deviates from the implied forward rate, an arbitrage opportunity exists. The fund manager can then exploit this opportunity by investing in the currency with the higher expected return, hedging the FX risk using the forward market. The calculation involves several steps. First, we calculate the future value of both investments. Then, we determine the implied forward rate based on interest rate parity. Next, we compare the implied forward rate with the actual forward rate. Finally, we calculate the expected return in the base currency (USD) for the UK investment. The investment with the higher expected return is the optimal choice. Let’s assume the spot rate is USD/GBP 1.25. UK interest rate is 5% and US interest rate is 2%. The forward rate is USD/GBP 1.22. Investing $1,000,000 in US treasury bill will yield $1,000,000 * (1 + 0.02) = $1,020,000. Investing $1,000,000 in UK treasury bill will yield $1,000,000 / 1.25 * (1 + 0.05) * 1.22 = $1,019,200. Therefore, investing in US treasury bill will yield higher return.

The question tests understanding of the interplay between different financial markets (money markets, capital markets, and derivatives markets) and how actions in one market can influence others, especially in the context of regulatory oversight. It also requires knowledge of how financial institutions manage risk and liquidity. Here’s the breakdown of the correct answer and why the others are incorrect: * **Correct Answer (a):** A significant withdrawal from money market funds could lead to a decrease in liquidity for these funds. To meet redemption requests, the funds might need to sell assets, potentially including short-term government securities. If this sale is large enough, it can put upward pressure on short-term interest rates in the money market. Because derivatives markets often use money market rates as benchmarks (e.g., for pricing interest rate swaps or futures), a change in money market rates will impact the pricing of these derivatives. The FCA, responsible for market stability, would monitor this situation because it could indicate broader liquidity issues or systemic risk. The sale of government bonds impacts their price, which inversely affects their yield. * **Why other options are incorrect:** * **(b):** While increased trading in FTSE 100 futures could indicate market sentiment, it’s less directly related to the immediate liquidity concerns arising from money market fund withdrawals. The FCA would be more concerned with the direct impact on money market stability. Furthermore, increased FTSE 100 futures trading primarily reflects sentiment about large-cap UK equities, not necessarily broader financial system liquidity. * **(c):** A surge in corporate bond issuances, although relevant to capital markets, doesn’t directly address the immediate liquidity crunch in the money market. While the FCA monitors corporate bond activity, the more pressing concern is the potential for contagion from the money market to other parts of the financial system. The increase in corporate bond issuance might even alleviate some pressure on the money market if investors shift funds from money market funds to higher-yielding corporate bonds, but the primary concern is still the potential for a run on money market funds. * **(d):** Increased trading volume in cryptocurrency markets is largely outside the direct regulatory purview of the FCA concerning traditional financial market stability. While the FCA has an interest in cryptocurrency regulation, a liquidity event in money market funds would be a higher priority due to its potential impact on regulated financial institutions and the broader economy. The FCA’s immediate concern would be the stability of regulated entities, not the volatility of unregulated crypto assets.

The Sharpe Ratio measures risk-adjusted return. It calculates the excess return per unit of total risk. The formula is: Sharpe Ratio = (Portfolio Return – Risk-Free Rate) / Portfolio Standard Deviation. A higher Sharpe Ratio indicates better risk-adjusted performance. In this scenario, we are given the portfolio return, risk-free rate, and the portfolio’s standard deviation. We can calculate the Sharpe Ratio by first finding the excess return (portfolio return minus the risk-free rate), and then dividing that by the standard deviation. Here’s the calculation: 1. Calculate the excess return: 12% – 2% = 10% 2. Convert percentage to decimal: 10% = 0.10 and 20% = 0.20 3. Calculate the Sharpe Ratio: 0.10 / 0.20 = 0.5 An analogy for understanding the Sharpe Ratio is comparing two mountain climbers. Both reach the same peak (return), but one takes a safer, more predictable route (lower standard deviation), while the other climbs a treacherous, unpredictable path (higher standard deviation). The climber with the safer route has a higher Sharpe Ratio because they achieved the same result with less risk. The Sharpe Ratio is important because it allows investors to compare the risk-adjusted returns of different investments. For instance, a fund manager might be tempted to chase higher returns by taking on excessive risk. However, a high Sharpe Ratio on a different, lower-return investment might indicate that the lower-return investment is actually a better choice because it provides a more favorable balance between risk and return. Understanding the Sharpe Ratio helps investors make informed decisions about where to allocate their capital.

The question explores the interplay between money market instruments, specifically Treasury Bills (T-Bills), and their impact on the foreign exchange (FX) market, under the influence of the Bank of England’s (BoE) monetary policy. The scenario involves the BoE unexpectedly decreasing the reserve requirement ratio, leading to increased liquidity in the banking system. This surplus liquidity, in turn, drives down short-term interest rates in the money market, making T-Bills less attractive to investors. The reduction in T-Bill yields affects the exchange rate through capital flows. A lower yield on T-Bills, relative to similar investments in other countries, reduces the demand for the domestic currency (GBP) as investors seek higher returns elsewhere. This decreased demand for GBP causes it to depreciate against other currencies. The question also considers the impact on derivative markets, specifically currency futures. A depreciating GBP would likely lead to increased demand for GBP futures contracts at lower prices, as investors anticipate future appreciation or seek to hedge against further depreciation. To calculate the approximate percentage change in the GBP/USD exchange rate, we need to estimate the impact of the T-Bill yield change on the exchange rate. Let’s assume the initial T-Bill yield was 1.5% and it decreased to 1.0%. This represents a 33.33% decrease in the yield (\(\frac{1.0 – 1.5}{1.5} \times 100\)). If we assume the exchange rate movement is proportionally related to the yield change (a simplification for illustrative purposes), and given an initial exchange rate of 1.25 GBP/USD, a depreciation of 1% would result in a new exchange rate of approximately 1.2375 GBP/USD (1.25 – (0.01 * 1.25)). Therefore, a rough estimate of the new exchange rate is calculated by reducing the initial rate by 1%, reflecting the impact of decreased T-Bill yields.

The question assesses the understanding of derivatives markets, specifically focusing on forward contracts and their relationship to spot prices, interest rates, and storage costs. The core concept is that the forward price reflects the future expected spot price, adjusted for the cost of carry. The cost of carry includes storage costs and the opportunity cost of capital tied up in the underlying asset (represented by the risk-free interest rate). The formula for the theoretical forward price is: Forward Price = Spot Price * (1 + Risk-Free Rate + Storage Costs) over the period. Let’s break down the calculation: 1. Calculate the total storage cost: £2.50/tonne/month * 6 months = £15/tonne 2. Calculate the interest cost: £350 * 0.05 * (6/12) = £8.75 3. Calculate the forward price: £350 + £15 + £8.75 = £373.75 The correct answer is £373.75. The other options represent common errors in calculating forward prices, such as neglecting storage costs, using an incorrect time period for interest calculation, or simply adding the interest rate instead of calculating the interest amount. To illustrate further, imagine a farmer who wants to sell their wheat harvest in six months. They could sell it immediately at the spot price or enter into a forward contract. If they sell immediately, they receive £350/tonne but incur storage costs and lose the potential interest they could earn on that money. By entering into a forward contract at £373.75/tonne, they effectively lock in a price that compensates them for these costs. This example demonstrates the practical application of forward contracts in managing price risk.

The question revolves around understanding the relationship between forward exchange rates, spot exchange rates, and interest rate differentials, specifically in the context of covered interest arbitrage. The formula that governs this relationship is derived from the principle that an investor should earn the same return regardless of whether they invest domestically or convert their currency, invest abroad, and then cover their foreign currency exposure back to their home currency using a forward contract. The core formula linking these variables is an approximation often used for simpler calculations: Forward Rate ≈ Spot Rate * (1 + (Interest Rate Differential * Time Period)) Where: * Forward Rate is the rate at which you agree to exchange currencies at a future date. * Spot Rate is the current exchange rate. * Interest Rate Differential is the difference between the domestic and foreign interest rates (domestic – foreign). * Time Period is the fraction of a year the investment covers. In this specific case, we are given the spot rate (USD/GBP = 1.25), the USD interest rate (3%), the GBP interest rate (5%), and the time period (9 months, or 0.75 years). We need to calculate the implied forward rate. First, calculate the interest rate differential: 3% – 5% = -2% or -0.02. Next, multiply the interest rate differential by the time period: -0.02 * 0.75 = -0.015. Then, add 1 to the result: 1 + (-0.015) = 0.985. Finally, multiply the spot rate by this factor: 1.25 * 0.985 = 1.23125. Therefore, the implied 9-month forward rate is approximately 1.2313 USD/GBP. This calculation demonstrates the concept of covered interest parity. If the actual forward rate deviates significantly from this calculated rate, an arbitrage opportunity exists. For instance, if the actual forward rate were higher than 1.2313, an investor could borrow GBP, convert it to USD at the spot rate, invest the USD, and simultaneously sell the USD forward at the higher rate. This locks in a profit when the USD is converted back to GBP at the forward rate, after accounting for interest earned and paid. Conversely, if the actual forward rate were lower, the opposite strategy would be employed: borrow USD, convert to GBP, invest in GBP, and buy USD forward. The slight difference between the approximate formula and the precise forward rate is due to compounding effects, but for exam purposes and quick estimations, the approximate formula provides a reasonable answer.

The core principle being tested is the relationship between interest rates, bond prices, and yield to maturity (YTM). When interest rates rise, newly issued bonds offer higher yields to attract investors. To compete, existing bonds with lower coupon rates become less attractive and their prices fall to increase their effective yield (YTM). Conversely, when interest rates fall, existing bonds with higher coupon rates become more attractive, and their prices rise. The yield to maturity represents the total return an investor can expect if they hold the bond until it matures, taking into account all coupon payments and the difference between the purchase price and the face value. In this scenario, the investor is concerned about mitigating interest rate risk. To minimize this risk, the investor should choose a bond with a short maturity. This is because the price of shorter-term bonds is less sensitive to changes in interest rates than the price of longer-term bonds. A shorter maturity means the investor’s capital is tied up for a shorter period, and they will reinvest the proceeds sooner at the prevailing interest rates, reducing the impact of interest rate fluctuations. Consider a bond with a 1-year maturity versus a bond with a 20-year maturity. If interest rates suddenly rise by 1%, the 20-year bond will experience a much larger price decline than the 1-year bond. This is because the investor is locked into the lower coupon rate for a much longer period with the 20-year bond. The investor will have to wait 20 years to get the face value back. The longer the time, the bigger the price decline will be. In contrast, the 1-year bond will mature quickly, and the investor can reinvest the proceeds at the new, higher interest rates. This protects the investor from the negative impact of rising interest rates. Therefore, the investor should choose the bond with the shortest maturity (5 years).

The scenario presents a complex interplay between different financial markets and instruments. To determine the most suitable action for mitigating risk, we need to understand the characteristics of each market and instrument. The money market deals with short-term debt instruments, while the capital market handles long-term securities like stocks and bonds. Foreign exchange (FX) markets involve currency trading, and derivatives markets offer contracts whose value is derived from underlying assets. In this case, the company faces currency risk due to fluctuating exchange rates impacting import costs. Derivatives, specifically currency forwards or options, are designed to hedge such risks. While money market instruments could provide short-term funding, they don’t directly address the currency risk. Capital market instruments like bonds are irrelevant to this immediate operational risk. The FX market allows direct currency exchange, but without a hedging strategy, it exposes the company to the very volatility it seeks to avoid. A currency forward contract allows the company to lock in a specific exchange rate for future transactions, thus eliminating the uncertainty caused by exchange rate fluctuations. A currency option gives the company the right, but not the obligation, to exchange currency at a predetermined rate, offering flexibility if the exchange rate moves favorably. The choice between a forward and an option depends on the company’s risk appetite and expectations regarding future exchange rate movements. However, both are superior to simply operating in the spot FX market without a hedging strategy. For example, imagine the company expects the GBP/USD rate to move adversely. A forward contract ensures they can buy USD at a known rate, protecting their profit margin. Conversely, if they used the money market to borrow GBP, they would still face the risk of a weaker GBP making the USD imports more expensive. Therefore, the most effective risk mitigation strategy involves using derivatives, specifically currency forwards or options, to hedge against exchange rate fluctuations.

The question revolves around understanding the interplay between different financial markets, specifically how movements in the money market (specifically, changes in the interbank lending rate, like SONIA) can influence investment decisions in the capital market (specifically, bond yields). It also tests knowledge of how foreign exchange rates can be affected. The scenario presented requires the candidate to consider these interconnected markets and assess the most likely outcome. An increase in SONIA suggests tighter liquidity conditions in the money market. Banks need to pay more to borrow from each other. This typically leads to a rise in short-term interest rates. Higher short-term rates can make money market instruments more attractive relative to longer-term bonds. Investors might shift funds from bonds to money market instruments, causing bond prices to fall and yields to rise. This is because the opportunity cost of holding a lower-yielding bond increases when short-term rates are higher. Furthermore, if the UK’s interest rates rise relative to other countries, it can attract foreign investment, increasing demand for the pound sterling and potentially causing it to appreciate. However, this appreciation can be tempered if the market perceives the rate hike as a sign of economic weakness or instability, which could lead to capital flight and a depreciation of the pound. The question asks for the *most* likely immediate impact, suggesting a focus on the initial reaction to the rate hike. Given the general principles, a rise in bond yields and a potential appreciation of the pound are more likely immediate effects.

The question assesses understanding of how different financial markets interact and how events in one market can influence others. Specifically, it focuses on the relationship between the money market (specifically, the interbank lending rate, SONIA) and the foreign exchange market (GBP/USD exchange rate). The key concept is that changes in interest rates influence currency values due to the impact on investment flows. A sudden increase in SONIA makes GBP-denominated assets more attractive to foreign investors, increasing demand for GBP and, therefore, strengthening the GBP/USD exchange rate. The magnitude of the change depends on various factors, including market expectations, the relative size of the interest rate change, and overall risk appetite. The scenario also introduces a hedging element, where the importer has a forward contract to mitigate exchange rate risk. The forward contract’s strike price becomes crucial in determining the actual cost of goods. If the spot rate moves significantly, the forward contract protects the importer from adverse movements, but also limits potential gains if the spot rate moves favorably. Here’s the breakdown of the calculation: 1. **Initial Cost:** £500,000 2. **Initial GBP/USD Spot Rate:** 1.25 3. **Initial USD Cost:** £500,000 * 1.25 = $625,000 4. **Forward Rate:** 1.26 (This is the rate the importer locked in) 5. **Hedged USD Cost:** £500,000 * 1.26 = $630,000 6. **SONIA Increase Impact:** GBP strengthens by 3% against USD. 7. **New Spot Rate:** 1.25 + (1.25 * 0.03) = 1.25 + 0.0375 = 1.2875 8. **Unhedged USD Cost at New Spot Rate:** £500,000 * 1.2875 = $643,750 9. **Difference between hedged and unhedged cost:** $643,750 – $630,000 = $13,750 Therefore, the importer saved $13,750 by using the forward contract. This example highlights how hedging can protect against adverse exchange rate movements, even when the underlying event (SONIA increase) initially appears favorable for the GBP. The forward contract provides certainty, which is valuable for budgeting and risk management, even if it means foregoing some potential gains. The scenario demonstrates the interconnectedness of money markets and foreign exchange markets and the importance of understanding these relationships for effective financial risk management. A similar analogy would be a farmer locking in a price for their crops using a futures contract. Even if the market price rises before harvest, they are protected from a price decrease, but also miss out on potential higher profits.

The efficient market hypothesis (EMH) posits that asset prices fully reflect all available information. There are three forms of EMH: weak, semi-strong, and strong. Weak form efficiency suggests that past price data cannot be used to predict future prices. Semi-strong form efficiency suggests that all publicly available information is reflected in prices. Strong form efficiency suggests that all information, public and private, is reflected in prices. In this scenario, the analyst’s use of publicly available data, such as company financial statements, news reports, and industry analysis, aligns with the semi-strong form of the EMH. If the market were semi-strong form efficient, this information would already be incorporated into the share price. Therefore, the analyst’s efforts to gain an edge using this publicly available information would be unlikely to generate abnormal returns consistently. However, real-world markets rarely perfectly adhere to any single form of EMH due to factors like behavioral biases, information asymmetry, and transaction costs. Even if a market tends towards semi-strong efficiency, temporary mispricings may occur due to delayed information dissemination or irrational investor behavior. The analyst’s success hinges on whether the market truly reflects all publicly available information instantly and accurately. If there are lags in information dissemination or if some investors systematically underreact to certain types of news, the analyst could potentially exploit these inefficiencies. For instance, if the analyst can process and interpret publicly available information faster or more accurately than the average investor, they might identify undervalued or overvalued securities before the market fully adjusts. Furthermore, behavioral finance suggests that cognitive biases can lead to predictable patterns of mispricing, even when information is widely available. In this case, the analyst’s approach may be successful if the market deviates from perfect semi-strong efficiency.

The core of this question lies in understanding how market efficiency impacts trading strategies, especially within the context of different market types (money market, capital market, FX market, derivatives market). The Efficient Market Hypothesis (EMH) posits that asset prices fully reflect all available information. However, the degree to which this holds true varies across markets and instruments. The money market, dealing with short-term debt instruments, is generally considered highly efficient due to the large volume of transactions, readily available information, and sophisticated participants. Conversely, certain segments of the derivatives market, especially those involving complex or less liquid instruments, may exhibit inefficiencies due to information asymmetry or limited participation. A fundamental concept is that in an efficient market, it’s difficult to consistently achieve above-average returns without taking on additional risk or possessing private information (which is illegal). Trading strategies based on publicly available information are unlikely to be profitable in the long run. Active trading, which involves frequent buying and selling in an attempt to “beat the market,” incurs transaction costs (brokerage fees, bid-ask spreads) that further erode potential profits. Therefore, in a highly efficient market, a passive investment strategy, such as buying and holding a diversified portfolio of money market instruments, is often the most sensible approach for an investor who does not possess an informational advantage. Consider a hypothetical scenario: An investor believes they have identified a mispriced commercial paper (a money market instrument) based on publicly available economic data. They plan to actively trade this paper, buying when they believe it’s undervalued and selling when it reaches their perceived fair value. However, because the money market is efficient, any perceived mispricing is likely to be quickly arbitraged away by other market participants. The investor’s trading costs may outweigh any potential gains from the short-lived mispricing, leading to a lower overall return compared to simply holding a diversified portfolio of similar instruments. The question also touches on the concept of regulatory arbitrage. Regulations impact market efficiency. If a market is lightly regulated, inefficiencies may persist longer, offering opportunities for sophisticated traders to exploit them (although this comes with increased risk). Conversely, stricter regulations tend to promote market efficiency by increasing transparency and reducing information asymmetry.

The yield curve is a graphical representation of yields on bonds with different maturities. It reflects market expectations about future interest rates and economic activity. A steepening yield curve, where the difference between long-term and short-term interest rates increases, typically indicates that investors expect higher future inflation and economic growth. The money market is where short-term debt instruments (typically with maturities of less than a year) are traded. Central banks use money market operations to influence short-term interest rates. An increase in short-term interest rates makes borrowing more expensive for banks, which in turn increases the cost of borrowing for consumers and businesses. This can slow down economic growth and reduce inflationary pressures. Foreign exchange (FX) risk arises from fluctuations in exchange rates. When a company has assets or liabilities denominated in a foreign currency, changes in the exchange rate can impact the value of those assets or liabilities. Hedging FX risk involves using financial instruments to mitigate the potential losses from adverse exchange rate movements. Options contracts are a common tool for hedging FX risk. In this scenario, a steepening yield curve suggests expectations of rising inflation. To combat this, the central bank raises short-term interest rates, impacting the money market. The treasurer needs to consider the FX risk associated with the company’s euro-denominated liabilities and implement a suitable hedging strategy. Given the expectation of rising interest rates, the treasurer should consider the impact on the cost of hedging. A put option gives the holder the right, but not the obligation, to sell an asset at a specified price (the strike price) on or before a specified date. In this case, buying a put option on EUR/GBP would protect the company against a depreciation of the euro against the pound. The premium paid for the option is the cost of this protection. A forward contract obligates the company to exchange currencies at a predetermined rate on a future date, eliminating the uncertainty of future exchange rates. If the treasurer expects the euro to depreciate significantly, a put option might be preferable because it provides downside protection while allowing the company to benefit if the euro appreciates. However, the premium cost must be weighed against the potential benefits. Given the rising interest rate environment, the forward rate might become more attractive if the interest rate differential between the UK and Eurozone widens, potentially making the forward rate more favorable for the company.

The question assesses understanding of how different financial markets operate and how specific instruments are traded within them. It requires distinguishing between the characteristics of money markets (short-term debt instruments) and capital markets (long-term debt and equity). It also tests the understanding of the role of market makers in providing liquidity. The correct answer highlights the key features of a money market transaction: short-term maturity, debt instruments, and the role of market makers. The incorrect options present plausible but ultimately inaccurate scenarios, such as confusing money market instruments with capital market instruments (shares), misunderstanding the short-term nature of money markets, or misattributing the role of market makers. Consider a small business, “TechStart,” needing short-term funding to cover a temporary cash flow gap while waiting for a large payment from a client. TechStart issues a commercial paper with a 90-day maturity. A market maker quotes a bid-ask spread on this commercial paper. The bid price represents the price at which the market maker is willing to buy the commercial paper from investors, and the ask price represents the price at which the market maker is willing to sell the commercial paper to investors. TechStart sells the commercial paper to the market maker at the bid price. The market maker then holds this commercial paper in its inventory, ready to sell it to other investors at the ask price. This activity provides liquidity in the money market, allowing TechStart to obtain short-term funding efficiently. Another example, suppose a large corporation has excess cash that it wants to invest for a very short period, say 30 days. The corporation could purchase treasury bills (T-bills) in the money market. These T-bills are short-term debt obligations issued by the government. Because of their short maturity and the government’s backing, T-bills are considered very low-risk investments. The corporation buys the T-bills through a broker who connects them to a market maker. The market maker facilitates the transaction, providing liquidity to the market.

The question explores the interconnectedness of money market rates, foreign exchange rates, and interest rate parity, specifically focusing on how deviations from the theoretical parity can create arbitrage opportunities and the role of market makers in correcting these imbalances. First, we calculate the theoretical forward rate implied by the interest rate parity. The formula for approximate interest rate parity is: Forward Rate ≈ Spot Rate * (1 + Interest Rate of Foreign Currency) / (1 + Interest Rate of Domestic Currency) In this case: Spot Rate = 1.25 USD/GBP Interest Rate of GBP (Domestic) = 5% = 0.05 Interest Rate of USD (Foreign) = 2% = 0.02 Theoretical Forward Rate ≈ 1.25 * (1 + 0.02) / (1 + 0.05) Theoretical Forward Rate ≈ 1.25 * (1.02) / (1.05) Theoretical Forward Rate ≈ 1.25 * 0.9714 Theoretical Forward Rate ≈ 1.2143 USD/GBP The market maker is quoting 1.22 USD/GBP, which is higher than the theoretical forward rate of 1.2143 USD/GBP. This means the GBP is relatively overpriced in the forward market compared to what the interest rate differential suggests. To exploit this arbitrage opportunity, an investor should borrow USD at 2%, convert it to GBP at the spot rate of 1.25 USD/GBP, invest the GBP at 5%, and simultaneously sell GBP forward at the market maker’s quoted rate of 1.22 USD/GBP. This locks in a profit because the return from investing in GBP and selling it forward exceeds the cost of borrowing USD. The market maker, by quoting a rate higher than the theoretical rate, is providing an opportunity for arbitrageurs to profit, which in turn will put pressure on the market maker to adjust the quoted forward rate downwards, aligning it closer to the theoretical parity. This adjustment occurs because arbitrageurs selling GBP forward increases the supply of GBP in the forward market, driving down its price. The actions of arbitrageurs act as a self-correcting mechanism in the foreign exchange market. When deviations from interest rate parity occur, arbitrageurs exploit the mispricing, which in turn pushes market rates back towards equilibrium. The market maker, facing losses from arbitrage activity, will adjust the quoted rates to eliminate the arbitrage opportunity. This continuous process ensures that the foreign exchange market remains efficient and that interest rate parity holds, at least approximately.

The question explores the interplay between money market instruments, specifically Treasury Bills (T-Bills), and the foreign exchange (FX) market. When a UK-based investment firm purchases US T-Bills, they must first convert GBP into USD. This conversion impacts the demand for both currencies. Increased demand for USD to purchase the T-Bills strengthens the USD relative to the GBP. Conversely, the increased supply of GBP, as it is sold to acquire USD, weakens the GBP. This change in the exchange rate affects the firm’s overall return when they later convert the USD proceeds from the T-Bill sale back into GBP. The calculation involves several steps: 1. **Initial Investment in USD:** The firm starts with £1,000,000 and converts it to USD at an initial exchange rate of 1.30 USD/GBP. This gives them \(£1,000,000 \times 1.30 = \$1,300,000\). 2. **T-Bill Purchase:** They use the \$1,300,000 to purchase US T-Bills. 3. **T-Bill Return:** The T-Bills yield a 2% return over 6 months. Thus, the return in USD is \(\$1,300,000 \times 0.02 = \$26,000\). The total amount received after 6 months is \(\$1,300,000 + \$26,000 = \$1,326,000\). 4. **Conversion back to GBP:** The exchange rate has changed to 1.25 USD/GBP. Converting the USD back to GBP yields \(\frac{\$1,326,000}{1.25} = £1,060,800\). 5. **Overall Profit:** The profit in GBP is \(£1,060,800 – £1,000,000 = £60,800\). The key takeaway is understanding how fluctuations in exchange rates can significantly affect the profitability of international investments, even when the underlying asset performs as expected. In this case, the weakening of the GBP against the USD between the initial investment and the repatriation of funds enhanced the overall return for the UK-based investment firm. This highlights the importance of considering exchange rate risk when making cross-border investments, particularly in money market instruments with relatively short maturities. For instance, if the GBP had strengthened instead, the profit would have been lower, or even a loss could have occurred, demonstrating the volatile nature of FX markets and their impact on investment outcomes.

The scenario presents a complex situation involving a company issuing bonds with a variable interest rate linked to SONIA (Sterling Overnight Index Average) plus a margin. Understanding how changes in SONIA impact the bond’s value is crucial. The initial SONIA rate and the margin are provided, allowing us to calculate the initial coupon rate. When SONIA increases, the coupon rate also increases. This directly affects the bond’s attractiveness to investors. To calculate the percentage change in the bond’s value, we need to consider the initial and new coupon payments and their effect on the present value of the bond. This calculation assumes a simplified scenario where the bond’s maturity is far enough into the future that the change in the current coupon rate significantly impacts the perceived value. Initially, the coupon rate is calculated as SONIA + Margin = 4.2% + 1.8% = 6%. The new coupon rate is SONIA + Margin = 4.7% + 1.8% = 6.5%. The percentage change in coupon payment is \[\frac{6.5\% – 6\%}{6\%} \times 100\% = \frac{0.5\%}{6\%} \times 100\% \approx 8.33\%\] This increase in coupon payment makes the bond more attractive, increasing its perceived value. The calculation represents a simplified model. In reality, bond pricing is more complex and involves discounting future cash flows based on prevailing market interest rates and the bond’s credit risk. However, in this scenario, we are primarily interested in the immediate impact of the SONIA rate change on the bond’s perceived value due to the change in the coupon rate. The assumption is that other factors remain constant. The increase in the coupon rate directly translates to an increase in the bond’s value.

The question assesses the understanding of how different financial markets interact and influence each other, specifically focusing on the impact of foreign exchange (FX) market volatility on capital markets. A weakening pound (GBP) against the US dollar (USD) makes UK assets cheaper for US investors, potentially increasing demand and driving up prices in the UK capital market (specifically the FTSE 100 in this scenario). However, this effect can be offset by other factors, such as concerns about the UK economy’s stability or the attractiveness of alternative investments in other markets. The question tests the ability to analyze these competing forces and determine the most likely outcome. The increase in demand from US investors can be modeled with a simple supply-demand framework. Imagine the FTSE 100 shares as a product. When the GBP weakens, it’s like a sale on UK assets for USD-based investors. This increases the demand for these assets. If supply remains constant (number of shares available), the increased demand will naturally push the price upwards. However, market sentiment and broader economic concerns can shift the demand curve. If investors are worried about a recession in the UK, even a cheaper price might not be enough to entice them, thus limiting the price increase. Furthermore, the strength of the US economy plays a crucial role. If the US economy is booming, investors might prefer to invest in US companies, even if UK assets are relatively cheaper. This represents an opportunity cost – the potential returns they could earn elsewhere. The question requires candidates to weigh these competing factors and determine the most likely outcome, reflecting the complex interplay of forces in financial markets. The correct answer acknowledges the initial upward pressure from FX movements but also considers the potential counteracting forces of economic sentiment and alternative investment opportunities.

The question tests understanding of the interplay between money markets, central bank policy, and their effect on broader capital markets, specifically focusing on bond yields. The Overnight Index Average (OIA) is a key rate in the money market, directly influenced by the central bank’s actions. Changes in the OIA ripple through the yield curve, impacting short-term and, to a lesser extent, long-term bond yields. The scenario presents a situation where the central bank unexpectedly lowers the OIA target. A decrease in the OIA target signals an easing of monetary policy. This makes it cheaper for banks to borrow money overnight, injecting liquidity into the money market. This increased liquidity pushes down short-term interest rates. Bond yields, which reflect the expected return on investment in bonds, are inversely related to bond prices. When interest rates fall, bond prices generally rise, and yields fall. The magnitude of the yield change depends on the bond’s maturity. Short-term bonds are more sensitive to changes in the OIA because their yields are directly linked to short-term interest rates. Long-term bonds are less sensitive because their yields reflect expectations about future interest rates and economic conditions over a longer horizon. The calculation demonstrates the impact of the OIA decrease on bond yields. We assume the 3-month bond yield decreases by the full amount of the OIA decrease (0.25%), while the 10-year bond yield decreases by a smaller amount (0.05%) due to its longer maturity and sensitivity to broader economic factors. New 3-month bond yield = Initial 3-month bond yield – OIA decrease = 4.50% – 0.25% = 4.25% New 10-year bond yield = Initial 10-year bond yield – Reduced impact = 4.75% – 0.05% = 4.70% This calculation illustrates how a central bank’s monetary policy decision, specifically lowering the OIA target, affects bond yields across different maturities. The scenario highlights the inverse relationship between interest rates and bond yields and the varying sensitivity of short-term and long-term bonds to changes in monetary policy.

The question revolves around the concept of market efficiency and how information asymmetry affects pricing in the context of a bond issuance. Specifically, it examines a scenario where a company, Solaris Dynamics, is issuing bonds and an unexpected regulatory change impacts their future profitability. The key is understanding that in an efficient market, new information should be rapidly incorporated into asset prices. However, the *degree* to which it’s incorporated depends on the market’s informational efficiency. In this case, the market is described as “semi-strong form efficient.” This means that all publicly available information should already be reflected in the bond price. The regulatory change is announced publicly. Therefore, the bond price *should* adjust. The tricky part is that the question introduces the concept of *investor sentiment* and *risk aversion*. Even if the market is semi-strong form efficient, extreme risk aversion can cause an *overshooting* of the price adjustment. Investors, fearing the worst, might sell off the bonds more aggressively than a purely rational assessment of the regulatory impact would warrant. To calculate the expected price change, we need to consider the present value of the reduced cash flows. The bond pays £50 annually. The regulatory change is expected to reduce Solaris Dynamics’ profits by £10 million per year, increasing the perceived risk of default. This increased risk translates to a higher required yield for investors. Let’s assume the bond has a face value of £1000 and an initial yield of 5%. A significant increase in perceived risk might push the required yield up to, say, 7%. We need to determine how this yield change impacts the bond’s price. Since we are not given the maturity of the bond, we will approximate the price change using the concept of duration. Duration measures the sensitivity of a bond’s price to changes in interest rates. A higher duration means a greater price change for a given change in yield. Without knowing the exact duration, we’ll use a simplified example. Let’s *assume* the bond has a duration of 7 years. A 2% (0.02) increase in yield would then lead to an approximate price decrease of 7 * 0.02 = 0.14, or 14%. Therefore, the bond price would decrease by approximately 14% of its face value (£1000), which is £140. However, due to high risk aversion, the price may decrease more than that. So the correct answer must be a value greater than £140.

The core of this question lies in understanding how different financial markets react to unexpected economic news and how that impacts specific financial instruments. We need to assess the interplay between money markets, foreign exchange markets, and the capital markets, specifically focusing on the bond market. The key is to recognize that a surprise increase in inflation expectations, especially when originating from a credible source like the Bank of England, will have cascading effects. First, the money market will react almost instantaneously. Banks and other financial institutions will anticipate the need for higher interest rates in the future to combat inflation. This will lead to an immediate increase in short-term interest rates as lenders demand a higher premium for the increased risk of inflation eroding the value of their loans. Second, the foreign exchange market will experience volatility. Higher interest rates in the UK, all other things being equal, should make the pound more attractive to foreign investors seeking higher returns. This increased demand for the pound would typically lead to its appreciation. However, the inflation news introduces uncertainty. If investors believe the Bank of England will struggle to control inflation, or that higher interest rates will stifle economic growth, the pound’s appreciation might be limited, or even reversed. The foreign exchange market’s reaction depends on the *net* effect of the higher interest rates and the inflation concerns. Third, the capital market, particularly the bond market, will experience a significant reaction. Bond prices and interest rates have an inverse relationship. When inflation expectations rise, investors demand a higher yield to compensate for the erosion of purchasing power. To achieve this higher yield, bond prices *must* fall. Longer-dated bonds are more sensitive to changes in interest rates because the inflation risk is compounded over a longer period. Therefore, longer-dated gilt prices will fall more sharply than shorter-dated ones. This is because the present value of future cash flows is discounted more heavily when interest rates rise. The yield curve will steepen as longer-term rates increase more than short-term rates. A flattening or inversion of the yield curve could signal recessionary concerns. Finally, gilt yields will increase because bond prices decrease. Remember, yields represent the total return an investor can expect if they hold the bond to maturity. The yield will rise to attract investors in the face of rising inflation expectations. The degree to which the yield increases depends on the market’s assessment of the credibility of the Bank of England’s response and the overall economic outlook. The yield curve represents the relationship between the yield and maturity of bonds.

The scenario describes a situation involving a UK-based manufacturing company, “Precision Components Ltd,” engaging in international trade. The company receives payment in US Dollars (USD) but operates primarily in British Pounds (GBP). This exposes them to foreign exchange risk, as fluctuations in the GBP/USD exchange rate can affect the value of their revenue when converted back to GBP. The question focuses on identifying the most suitable financial instrument to mitigate this risk. A forward contract is a customized agreement between two parties to buy or sell an asset at a specified future date at a price agreed upon today. This is an over-the-counter (OTC) product. In this scenario, Precision Components Ltd. can enter into a forward contract to sell USD and buy GBP at a predetermined exchange rate. This eliminates the uncertainty of future exchange rate movements, allowing them to lock in a specific GBP value for their USD revenue. A currency option gives the holder the right, but not the obligation, to buy or sell a currency at a specified exchange rate on or before a specified date. This provides flexibility but comes at the cost of a premium. While useful in some situations, it’s not the most direct solution for simply hedging against a known future USD receipt. A money market hedge involves borrowing in one currency, converting it to another, and investing it. This is a more complex strategy and may not be as efficient as a forward contract for a straightforward hedging need. It also involves taking on debt. A spot transaction involves the immediate exchange of currencies at the current exchange rate. This does not provide any hedging against future exchange rate movements. In this case, the forward contract offers the most direct and certain way for Precision Components Ltd. to protect itself from adverse exchange rate fluctuations. It allows them to fix the GBP value of their USD receipts in advance, making it the most suitable hedging instrument.

The question explores the interplay between the Bank of England’s (BoE) monetary policy, specifically quantitative tightening (QT), and its impact on different segments of the financial markets. QT involves the BoE selling assets (primarily government bonds) back into the market or allowing them to mature without reinvestment. This action reduces the amount of reserves commercial banks hold at the BoE, effectively shrinking the money supply. Let’s consider the impact on each market segment: * **Money Markets:** QT directly affects money markets. As the BoE reduces reserves, banks have less liquidity to lend in the short-term money markets (e.g., the interbank lending market, the commercial paper market). This increased scarcity of funds tends to push short-term interest rates higher. Imagine a farmer’s market where the supply of apples suddenly decreases. The remaining apples become more valuable, and the price increases. Similarly, reduced liquidity in the money market makes funds more expensive. * **Capital Markets:** The effects on capital markets are more indirect but still significant. Higher short-term interest rates can influence long-term interest rates (yields on government bonds and corporate bonds). Investors might demand higher yields on longer-term bonds to compensate for the increased cost of borrowing and the potential for inflation. This can lead to a decrease in bond prices. Furthermore, higher interest rates can make borrowing more expensive for companies, potentially dampening investment and economic growth, which can negatively affect equity markets. Think of a bridge construction project. If the cost of borrowing money (interest rates) increases significantly, the project might become less financially viable, potentially leading to delays or cancellation, affecting the value of related companies. * **Foreign Exchange Markets:** QT can influence the exchange rate. Higher interest rates in the UK can attract foreign investment, as investors seek higher returns. This increased demand for the British pound (£) can cause it to appreciate against other currencies. For example, if a Japanese investor can earn a higher return on UK government bonds than on Japanese government bonds, they might convert yen into pounds to invest, increasing the demand for pounds. * **Derivatives Markets:** The impact on derivatives markets is complex and depends on the specific derivatives. Interest rate derivatives (e.g., interest rate swaps, options on interest rates) are directly affected by changes in interest rates caused by QT. Equity derivatives (e.g., options on stock indices) can be affected indirectly through the impact of QT on equity markets. Currency derivatives (e.g., currency futures, currency options) are affected by changes in exchange rates. Imagine a set of interconnected gears. The BoE’s QT is like turning one gear (money market), which then affects the other gears (capital markets, foreign exchange markets, and derivatives markets) to varying degrees. Therefore, the most immediate and direct impact of quantitative tightening is felt in the money markets due to the direct reduction of reserves available to commercial banks for short-term lending.

The question revolves around the interplay between money markets and capital markets, specifically how actions in one can influence the other, and how regulatory changes can impact these relationships. The scenario involves a fictional regulatory body, the “Financial Stability Oversight Authority” (FSOA), implementing a new rule impacting the liquidity requirements of banks. This rule necessitates banks to hold a higher percentage of their assets in highly liquid forms, directly impacting their activity in both the money and capital markets. The money market is where short-term debt instruments are traded, often overnight or for a few months. Banks use this market to manage their short-term liquidity needs, borrowing and lending reserves to meet regulatory requirements or take advantage of short-term investment opportunities. An increase in liquidity requirements, as posited by the FSOA rule, forces banks to seek out more liquid assets, increasing demand in the money market. This increased demand puts upward pressure on short-term interest rates, as banks compete for the limited supply of liquid funds. The capital market, on the other hand, deals with longer-term debt and equity instruments. While seemingly distinct, the money market and capital market are interconnected. Higher short-term interest rates in the money market can influence long-term interest rates in the capital market. Investors may demand higher yields on long-term bonds to compensate for the higher returns available in the short-term money market. Furthermore, the increased demand for liquid assets may lead banks to reduce their investments in longer-term, less liquid assets in the capital market. This could include selling off portions of their bond portfolios or reducing their lending activity to businesses. This reduction in investment can lead to a decrease in the availability of capital for businesses, potentially slowing economic growth. The correct answer highlights the impact on short-term interest rates and the potential dampening effect on capital investment. The incorrect answers present plausible but flawed scenarios, such as a decrease in short-term rates (which contradicts the increased demand for liquidity) or an increase in capital investment (which contradicts the need for banks to hold more liquid assets). Understanding the interplay between these markets and the impact of regulatory changes is crucial for financial professionals. The question tests the candidate’s ability to connect regulatory actions to market responses, showcasing a deeper understanding of financial market dynamics.

The core concept being tested is the understanding of how macroeconomic factors, specifically interest rate changes and inflation expectations, impact the valuation of different financial instruments in the capital markets. The question probes beyond simple definitions and requires the candidate to apply their knowledge to a novel scenario involving a hypothetical company and its bond issuance strategy. The correct answer hinges on recognizing that rising interest rates generally decrease bond prices (inverse relationship). Furthermore, increased inflation expectations erode the real return on fixed-income investments, further depressing bond prices. The scenario presents a company strategically delaying its bond issuance, and the question assesses whether the candidate can correctly predict the combined impact of these economic forces on the bond’s potential yield and price. The incorrect options are designed to be plausible by incorporating common misconceptions. One incorrect option suggests that the delay would be beneficial due to lower interest rates (opposite of the scenario). Another suggests that inflation expectations would have a minimal impact, which is incorrect. The final incorrect option focuses solely on the interest rate impact, neglecting the crucial role of inflation expectations. The scenario involves calculating the potential yield change based on the combined effect of a 0.75% interest rate increase and a 0.5% rise in inflation expectations. The company initially planned to issue bonds with a 4% yield. The new yield would be \(4\% + 0.75\% + 0.5\% = 5.25\%\). The price of the bond would decrease due to the higher yield. The calculation is implicitly testing the understanding that bond prices and yields move inversely. A bond initially priced at par would now trade at a discount to offer the increased yield. This tests a deeper understanding of bond valuation principles.

The core of this question revolves around understanding the interplay between different financial markets and how events in one market can cascade into others. Specifically, it examines the scenario of a sudden devaluation in the foreign exchange market and its potential impact on a company heavily reliant on imported raw materials and operating in the capital market (issuing bonds). The key to solving this lies in recognizing that a currency devaluation makes imports more expensive. This increased cost of raw materials directly impacts the company’s profitability and, consequently, its ability to meet its debt obligations (bond repayments). Investors, anticipating a potential downgrade in the company’s credit rating due to weakened financials, will demand a higher yield to compensate for the increased risk. This increased yield translates to a lower bond price in the secondary market. Let’s illustrate with a hypothetical example. Imagine a UK-based manufacturing firm, “BritFab,” which imports 70% of its raw materials from the Eurozone. BritFab has outstanding bonds with a face value of £100 million. Initially, the exchange rate is £1 = €1.20. Suddenly, due to unforeseen economic circumstances, the pound devalues to £1 = €1.00. This means BritFab now needs to spend more pounds to buy the same amount of Euros, increasing its raw material costs by approximately 20% (calculated as \[\frac{1.20 – 1.00}{1.00} \approx 0.20\] or 20%). If BritFab’s profit margins were already thin, this could significantly impact their ability to service their debt. The question also touches upon the role of credit rating agencies. These agencies assess the creditworthiness of companies and their debt instruments. A devaluation-induced financial strain would likely lead to a downgrade, further fueling investor concerns and driving down bond prices. Therefore, the correct answer reflects the combined impact of increased costs, potential credit rating downgrade, and increased investor risk aversion leading to lower bond prices.

The question assesses the understanding of the impact of interest rate fluctuations on bond prices and the inverse relationship between them. The calculation involves using the approximate duration formula to estimate the percentage change in the bond’s price given a change in yield. The formula is: Percentage Change in Bond Price ≈ -Duration × Change in Yield. The duration is given as 7.5 years, and the yield change is 0.75% or 0.0075. The negative sign indicates the inverse relationship. Therefore, the percentage change is approximately -7.5 × 0.0075 = -0.05625 or -5.625%. This means the bond price is expected to decrease by approximately 5.625%. Now, let’s delve into the reasoning behind this relationship and the significance of duration. Imagine a seesaw, where the fulcrum represents the present value of future cash flows from the bond. On one side of the seesaw, you have the earlier cash flows (coupon payments), and on the other side, you have the later cash flows (principal repayment). Duration is essentially the balancing point of this seesaw, indicating the weighted average time until you receive the bond’s cash flows. A higher duration means the seesaw is more sensitive to changes in the fulcrum’s position (interest rates). Consider a scenario where interest rates rise. The present value of future cash flows, especially those further in the future, decreases more significantly. This is because the discount rate used to calculate the present value is higher. For a bond with a high duration, the later cash flows are a larger proportion of the bond’s total value, making it more susceptible to interest rate changes. Conversely, a bond with a low duration is less sensitive because its cash flows are received sooner, and their present values are less affected by interest rate changes. Furthermore, the approximate duration formula provides a linear estimate of the price change, which is most accurate for small changes in yield. For larger yield changes, the actual price change may deviate from the estimate due to the convexity effect, which is not considered in the simple duration calculation.
