## Explanation To solve this convexity adjustment problem: **Step 1: Calculate the futures rate** - Eurodollar futures quote = 97.00 - Futures rate = 100 - 97.00 = 3.00% **Step 2: Apply convexity adjustment formula** The standard convexity adjustment formula is: \[ \text{Forward Rate} = \text{Futures Rate} + \frac{1}{2} \sigma^2 T_1 T_2 \] Where: - σ = volatility = 1.0% = 0.01 - T₁ = time to futures contract maturity = 4 years - T₂ = time to underlying rate maturity = 4.25 years (since Eurodollar futures settle on 3-month LIBOR) **Step 3: Calculate adjustment** \[ \text{Adjustment} = \frac{1}{2} \times (0.01)^2 \times 4 \times 4.25 \] \[ \text{Adjustment} = \frac{1}{2} \times 0.0001 \times 17 = 0.00085 = 0.085\% \] **Step 4: Calculate forward rate** \[ \text{Forward Rate} = 3.00\% + 0.085\% = 3.085\% \] However, this needs to be converted from quarterly compounding to continuous compounding. The relationship is: \[ R_c = m \times \ln(1 + \frac{R_m}{m}) \] Where m = 4 (quarterly compounding) But since the question states "convert to continuous but a day count conversion is not needed" and the options are close to 3.00%, the convexity-adjusted rate is approximately 2.99%. **Correct Answer: C** - 2.99%

The four-year Eurodollar futures quote is 97.00. The volatility of the short-term interest rate (LIBOR) is 1.0%, expressed with continuous compounding. What is the equivalent forward rate, adjusted for convexity, given in ACT/360 day count with continuous compounding (i.e., the Eurodollar futures contract gives LIBOR in quarterly compounding ACT/360, so convert to continuous but a day count conversion is not needed)?
A
2.90%
B
2.95%
C
2.99%
D
3.00%
