Based on economists forecasts and analysis, one-year Treasury bill rates and liquidity premiums for the next four years are expected to be as follows:

₁R₁ = 5.8%, E(₂r₁)=6.4%, L2=0.1%, E(₃r₁)= 6.9%, L3=0.2%, E(₄r₁)=7.5%, L4=0.3%

Using the liquidity premium hypothesis, calculate the current rate for the three-year Treasury security.
