Rho is a measure of the sensitivity of an option's price to changes in interest rates. If rho is positive, it means that the price of the option will increase when interest rates rise. This is because higher interest rates generally increase the cost of carry, which can make holding the underlying asset more expensive and thus increase the value of the option.

The risk manager is analyzing a long position worth USD 10 million. To hedge this portfolio, the risk manager uses options that decrease in value by JPY 0.50 for every JPY 1 increase in the long position. This effectively means the options are shorting the currency. Therefore, if the long position is fully hedged by these options, the overall exposure of the portfolio will be equivalent to the full value of the long position but in the opposite direction. Thus, the portfolio has the same exposure to USD as a portfolio that is short USD 10 million.

The formula to estimate a partial change in an option's price based on the change in the underlying asset's price is primarily dependent on the option's Delta. Delta represents the sensitivity of the option's price to changes in the price of the underlying asset. Therefore, the most straightforward and widely used formula to estimate this partial change is:Partial change in option price=Δ×Change in underlying pricePartial change in option price=Δ×Change in underlying priceThis formula directly utilizes Delta to measure the immediate rate of change in the option's price relative to a small change in the underlying asset's price. The other options involving Gamma are more complex and not typically used for simple partial changes.

Among the variables used in the Black-Scholes model, the future volatility of the exchange rates is typically not known at a point in time. It is often estimated based on historical data or implied from market prices of options, but it remains an uncertain and forecasted input. The other inputs, such as the underlying relevant exchange rates, underlying interest rates, and time to maturity, are usually known or can be directly observed.

References:The inherent uncertainty in predicting future volatility is discussed in the context of option pricing in the "How Finance Works" document​​.

Model Definition: Credit scoring models are typically used to grade the creditworthiness of small- and medium-sized enterprises (SMEs).

Application: These models evaluate the credit risk of SMEs by considering various financial and non-financial parameters, providing a systematic and quantitative method to determine credit scores.​

Market-linked credit risk drivers often face specific disadvantages:

Need to supply a large number of input parameters to the model: Complex models require numerous data inputs, which can be challenging to obtain and maintain.

Slow computation speed due to higher simulation complexity: The complexity of these models can lead to slower computation times, making them less efficient for real-time analysis.

Non-linear nature of models and the need to estimate unknown variables are also relevant but are not as primary disadvantages as the first two mentioned.

Vega represents the sensitivity of an option's price to changes in the volatility of the underlying asset. If a call option on the GBP has a Vega of 0.02, this means that for every 1% increase in the perceived future volatility, the price of the call option will increase by 0.02. Therefore, if the volatility increases by 1%, the call option's value increases by 0.02.

Delta is the most commonly used risk measure to determine the number of options needed to hedge an underlying position. Delta measures the sensitivity of the option's price to changes in the price of the underlying asset. A delta-neutral portfolio, where the total delta is zero, effectively hedges against small movements in the underlying asset's price. Thus, risk managers frequently adjust their hedging strategies based on the delta of their positions.

To determine the bank's expected loss, we need to calculate the expected loss given default (LGD) and then use the annual expected default rate to find the total expected loss.

Loan Amount (Exposure at Default, EAD): $100,000

Collateral: $55,000

Net Exposure (EAD - Collateral): $100,000 - $55,000 = $45,000

Loss Given Default (LGD): 50% of Net Exposure ????????????=50%×$45,000=$22,500LGD=50%×$45,000=$22,500

Annual Expected Default Rate: 2%

Expected Loss: Annual Expected Default Rate × LGD Expected Loss=2%×$22,500=0.02×22,500=$450Expected Loss=2%×$22,500=0.02×22,500=$450

Hence, the expected loss due to default is $450, but we need to find the total expected loss including the interest, which is typically considered the exposure part.

Total expected loss is primarily focusing on the loan risk and the direct calculation of LGD × Default Rate.

A decrease in inflation rates typically leads to an increase in the price of fixed income instruments like bonds. Lower inflation increases the real value of the fixed payments received from bonds, making them more attractive to investors and driving up their prices.
