This verbal formulation does not match what interest rate parity states. Note that there are two versions of interest rate parity: covered interest rate parity (an arbitrage condition), and uncovered interest rate parity (an equilibrium condition that appears questionable).

See this question for a description of interest rate parity: [link to question](https://economics.stackexchange.com/questions/4914/interest-rate-parity-counter-intuitive) I will not repeat the description of interest rate parity, as it is done in that answer.

In both versions of interest rate parity, what matters is *expected* depreciation, not a historical event of depreciation.

The statement that interest rates adjust in reaction to expected exchange rate movements is also questionable. Short-term rates are largely under control of central banks in floating currencies, and so a more plausible description is that expected currency movements conform to interest rate differentials.
