The external interest rate effect:

Is the return from the implied forward rates (expected return) considered as the same as the market implied return from forward rates (unexpected return)?

For instance,

Implied Forward Rate (expected return) = 5%

Market implied return from forward rate = 5%

Actual realized return = 6%

Therefore, the unexpected return is actual realized return - market implied return from forward rate => 6% - 5% = 1%,

Actual return is expected return + unexpected return => 5% + 1% = 6%
