It is the changes in domestic interest rate (iT) paid for Turkish lira assets.

It shouldn't be the interest rate paid for dollar deposits (i $) and the expected foreign exchange rate (Eet+1).

It is not the current exchange rate that this point indicates (1$ = 1.00T) is the equilibrium foreign exchange rate.

The increase of the US interest rate in international markets doesn't cause depreciation of the domestic currency ( Turkish lira).

An increase in i$ also doesn't mean an increase in the expected return of dollar nominated deposits.
