Answer:
3.05%
Explanation:
According to Pure Expectation Theory, the future short term interest rates are actually the forward rates.
Mathematically,
(1 + r2,0)^2 = (1 + r1,0)^1 * (1 + r1,1)^1
Here,
r2,0 is the rate of interest for 2 year treasury security from today
r1,0 is the rate of the interest for 1 year treasury security from today
r1,1 is the rate of the interest for 2 year treasury security from Year 1
By Putting Values, we have:
(1 + r2,0)^2 = (1 + 0.04)^1 * (1 + 0.021)^1
(1 + r2,0)^2 = 1.06184
By taking square-root on both sides, we have:
(1 + r2,0) = 1.0305
r2,0 = 3.05%
