Reading 64: Interest Rate Derivative Instruments Los b~Q2

interest, situation, concerned, management, liability

Q2. Mark Austin is a risk management consultant specializing in fixed income securities. He has been asked to evaluate the interest rate risk situation of an intermediate size bank. The bank has a large floating rate liability of $100,000,000 on which it pays the London Inter Bank Offered Rate (LIBOR) on a quarterly basis. Austin is concerned about the significant interest rate risk the bank incurs because of this liability. Since most of the bank's assets are invested in fixed rate instruments there is a considerable duration mismatch. Some of the bank's assets are floating rate notes tied to LIBOR. However, the total par value of these securities is significantly less than the liability position.

Austin considers both swaps and interest rate options. The interest rate options are 2-year caps and floors with quarterly exercise dates. He wishes to hedge the entire liability.

Austin has the technology to be able to generate an interest rate tree resulting in the quarterly incremented interest rate tree and the corresponding pricing tree for a two-year caplet shown in Table 1.

He has also obtained the prices for an at-the-money 6 month cap and floor with quarterly exercise. These are shown in Table 2.

Q2.

Correct answer is A)fficeffice" />

Buying a cap combined with a floating rate liability limits the exposure to interest rate increases (no exposure to interest rate increases above strike rate) while the floating rate borrower is still able to benefit from interest rate decreases.
