7. Consider a F/I with the following balance sheet: Assets consisting of Cash of $150M; Loans of $1,500M at 12% with a duration of 1.75 years; and, Treasuries of $350M at 9% with a 7.00 year duration. Liabilities consisting of time deposits of $700M at 7% with a 1.75 year duration; CDs of $1,150M at 8% with a duration of 2.50 years; and, equity of $150M. Calculate the duration gap and state the F/I's interest rate risk exposure.

 +1.03 years; exposed to interest rate increases.  |

| 
 +0.32 years; exposed to interest rate increases.  |

| 
 +0.86 years; exposed to interest rate increases.  |

| 
 +0.49 years; exposed to interest rate increases.  |

| 
 -1.32 years; exposed to interest rate decreases.  | 
Solution: CORRECT ANSWER is D) +0.49 years; exposed to interest rate increases.
| Assets | Market Value | Yield | Duration(Years) | 
| Cash | 150 | ||
| Loans | 1500 | 12.00% | 1.75 | 
| Treasuries | 350 | 9.00% | 7 | 
| Total assets | 2000 | ||
| Liabilities | Market Value | Rate | Duration Years | 
| Time Deposits | 700 | 7.00% | 1.75 | 
| CDs | 1150 | 8.00% | 2.5 | 
| Total liabilities | 1850 | ||
| Equity | 150 | ||
| Total | 2000 | 
| Weighted Average Duration of Bank assets (Da) = Summation of the product of weights of individual assets and their respective Duration years. Where, weight of individual asset = Market value of that asset divided by the market value of all bank assets | (1500/2000)*1.75 + (350/2000)*7 = 2.5375 | 
| Weighted Average Duration of Bank Liabilities (Dl) = Summation of the product of weights of individual liabilities and their respective Duration years. Where, weight of individual liability = Market value of that liability divided by the market value of all bank liabilities | (700/1850)*1.75 + (1150/1850)*2.5 = 2.216 | 
| Duration Gap = Weighted average duration of assets -(Market value of liabilities/Market value of assets)*(Weighted average duration of liabilities) = (2.5375) - ((1850/2000)*2.216) = 0.4875 | +0.49 | 
The duration gap is +0.49 and positive duration gap means that the market value of equity of F/I will fall when interest rates rise. So, F/I is exposed to interest rate increases.
