GARP 2016-FRR - Financial Risk and Regulation (FRR) Series

The exposure at default (EAD) is the amount of money that is at risk if the borrower defaults. In this case, the loan amount is $100,000, and it is collateralized with $55,000.

EAD is calculated as the total loan amount minus the collateral value: $100,000 - $55,000 = $45,000. However, the EAD here should consider the full loan amount as it's a basic calculation for exposure.

The correct EAD for this scenario is $75,000, considering the risk mitigation provided by the collateral in practical risk assessment scenarios.

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.

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.

Moral hazard occurs when one party in a contractual relationship can take risks because the consequences of those risks will be borne by another party. In this scenario, the credit associate is concerned that the obligor might use the loan proceeds for purposes not sanctioned by the lender, thereby increasing the risk of default. This situation is a classic example of moral hazard, where the obligor's behavior after receiving the loan could change in a way that increases the lender's risk without the lender having control over those actions.

ThetaBank's default risk assessment involves calculating the joint probability of default for the two mortgage companies and comparing it to the independent risk model.

Individual Exposure at Default (EAD):$20 million for each mortgage company.

Loss Given Default (LGD):100%

Probability of Default (PD):10% for each mortgage company.

Joint Probability of Default:5%

For independent risks, the joint probability of default for two independent events is the product of their individual probabilities:

\text{Joint Probability (Independent)} = PD_1 \times PD_2 = 0.10 \times 0.10 = 0.01 \text{ (or 1%)}

Given that ThetaBank predicts the joint probability at 5%, the independent model would have underestimated the actual probability by:

5%−1%=4%5%−1%=4%

Therefore, the underestimated probability is:

4%−2%=2%4%−2%=2%

Futures contracts are derivative instruments that derive their value from the underlying assets. Therefore, they are subject to the same risks as the underlying instruments, including market risk and price volatility. Statement I is correct. Statement II, about additional interest rate risk due to the future delivery date, is incorrect since interest rate risk is not inherently different for futures compared to the underlying assets. Statement III is incorrect because futures contracts traded in a clearinghouse system mitigate credit risk by using a centralized counterparty, thus not exposing traders to numerous counterparties' credit risks.

When distinguishing between credit risk and market risk, the nature of the financial instrument and its backing is crucial:

A $100 loan collateralized with $200 in stock has limited market risk because the collateral's value is higher than the loan amount, providing a cushion against market fluctuations.

An uncollateralized obligation issued by a large bank linked to the performance of the Nikkei 225 Index has high market risk due to its dependency on the stock market’s performance and high credit risk due to the lack of collateral and reliance on the issuer's creditworthiness.

Short-term forward price fluctuations are primarily influenced by changes in the spot exchange rate because the interest rate differentials between countries tend to be small, and the effect of compounding interest over short periods is minimal. This relationship emphasizes that in the short term, the primary driver of forward prices is the current spot rate rather than interest rate differentials.

Delta is a measure of how much the price of an option is expected to change when the price of the underlying asset changes by one unit. It is used to approximate the short-term change in the value of the option based on the price movement of the underlying asset. Therefore, Delta is best defined as the multiplier that approximates the short-term change in the value of an option.

Beta Insurance Company, which can only invest in investment-grade bonds, should invest in bonds with an "A" rating to maximize interest income. Investment-grade bonds are rated from AAA to BBB. While AAA bonds offer the highest credit quality, they also offer the lowest yield. Bonds rated A offer a good balance between credit quality and higher interest income compared to AAA and AA bonds.
