CMB - Certified Mortgage Banker Advanced Portfolio Management Questions and Answers

Question 1

A mortgage company holds a significant portfolio of Mortgage Servicing Rights (MSRs) and has implemented a corresponding hedging strategy. If market interest rates experience a sudden and sharp decline of 100 basis points, what is the most likely combined impact on the MSR portfolio and its hedge?

Accepted Answer

The MSR value will decrease due to increased prepayment risk, and the hedge value will increase.

Answer

MSRs have negative duration; their value decreases when interest rates fall because lower rates incentivize refinancing. This shortens the life of the servicing asset and reduces the expected future income stream. A proper hedge is designed to have positive duration, meaning its value will increase when rates fall, thereby offsetting the loss on the MSR asset.

Question 2

A portfolio manager for a large bank holds a substantial portfolio of newly originated, high-quality jumbo mortgages. To reduce the bank's regulatory capital requirements and mitigate credit default risk without selling the actual loans, which of the following strategies would be most effective?

Accepted Answer

Executing a Credit Risk Transfer (CRT) transaction with institutional investors.

Answer

Credit Risk Transfer (CRT) transactions are specifically designed to transfer the credit risk of a portfolio to other parties (investors) in exchange for a fee, while the original holder often retains the assets on its balance sheet. This reduces the holder's credit exposure and associated regulatory capital requirements. Selling the loans (securitizing) removes the asset entirely, which is not the stated goal.

Question 3

In evaluating portfolio performance, a manager wants to compare different asset classes (e.g., QM, Non-QM, FHA) by considering not just their returns, but also the amount of economic capital required to support the risk of each asset class. Which performance metric is most appropriate for this type of analysis?

Accepted Answer

Risk-Adjusted Return on Capital (RAROC)

Answer

RAROC is a framework that measures return relative to the economic capital at risk. It is ideal for comparing the profitability of different business lines or asset classes because it normalizes returns based on the specific risk and capital required for each, allowing for an apples-to-apples comparison. ROA, NIM, and Efficiency Ratio do not directly incorporate risk-based capital allocation in their formulas.

Question 4

A mortgage bank's secondary marketing department has a large pipeline of locked loans funded by a warehouse line of credit. The warehouse lender, concerned about market stability, unexpectedly increases the 'haircut' from 2% to 5% for all loan types. What is the most immediate and critical consequence for the bank?

Accepted Answer

A significant increase in the bank's immediate liquidity requirement.

Answer

The 'haircut' is the portion of the loan amount that the bank must fund with its own capital. Increasing the haircut from 2% to 5% means the bank must now put up 5% of the loan amount for each loan instead of 2%. This significantly increases the immediate cash (liquidity) needed to fund the same volume of loans, straining its capital resources.

Question 5

A depository institution holds a large portfolio of 30-year fixed-rate mortgages as assets, while its primary liabilities are short-term customer deposits. If the central bank signals a sustained period of rising interest rates, what is the primary asset-liability management (ALM) risk the institution faces?

Accepted Answer

Net interest margin (NIM) compression due to a duration mismatch.

Answer

This scenario describes a classic duration mismatch. The bank's cost of funds (interest paid on short-term deposits) will rise quickly along with market rates. However, the yield on its long-term, fixed-rate mortgage assets will remain static. This causes the spread between asset earnings and liability costs—the Net Interest Margin (NIM)—to shrink, directly impacting profitability. Prepayment risk is the primary concern in a falling rate environment.
