Answer:
0.142%
Step-by-step explanation:
We are required to find the liquidity premium on the four-year Treasury security (L4)
1R4 = 1.4%
1R3 = 1.22%
E(4r1) = 1.8%
1 + 1R4 = [{(1+1R3)^3} * (1+E(4R1) + L4)]^1/4
1 + 0.014 = [{(1 + 0.0122)^3) * (1+0.018 + L4)]^1/4
1.014^4 = [{(1 + 0.0122)^3) * (1+0.018 + L4)]
1.057187 = (1.0370483) * (1.018 + L4)
1.057187/1.0370483 = 1.018 + L4
1.0194192 = 1.018 + L4
L4 = 1.0194192 - 1.018
L4 = 0.00142
L4 = 0.142%
Hence, liquidity premium on the four-year Treasury security(L4) = 0.142%
