8) Why would lowering its own interest rates affect a nation's exchange rate?

A) International interest arbitrage would cause investors to sell domestic currency assets and purchase foreign assets based in other currencies.

B) A nation's central bank controls both interest rates and exchange rates. So when interest rates are lowered, the exchange rate also goes down.

C) When interest rates fall, borrowing is cheaper, spending and GDP rise and so do exports, thus causing the exchange rate to appreciate.

D) In the short run, exchange rates have to adhere to PPP; otherwise, traders will make profits by purchasing in the cheap market and selling in the more expensive market, thus aligning exchange rates at the proper level.
