FRM Part I · FRM Exam Part I · Interest Rates

Annually compounded spot rates are 2.0% for one year, 3.0% for two years and 4.0% for three years. What is the implied one-year forward rate two years from now (the 2y1y forward), to the nearest basis point?

The 2y1y forward rate is about 6.03%, computed as (1.04)^3 divided by (1.03)^2 minus one. The forward is the rate that makes investing for two years then one more year equal to investing for three years at the three-year spot rate.

  1. A5.00%
  2. B5.01%
  3. C6.03%Correct
  4. D6.00%

Explanation

(1.04)^3 = 1.124864 and (1.03)^2 = 1.0609. Ratio = 1.124864/1.0609 = 1.06029, so the forward is about 6.03%. The simple-average shortcut of 5.00% ignores compounding, and 6.00% is only a rounded approximation.
