What is the negative side effect on the money supply of a non-sterilized foreign exchange intervention?

Question

Quizplus · Accepted Answer

In a non-sterilized foreign exchange intervention, the central bank purchases or sells foreign currency in the exchange market, which affects the domestic money supply. If the central bank buys foreign currency, it pays for it with domestic currency, which increases the money supply. Conversely, if the central bank sells foreign currency, it receives domestic currency, which decreases the money supply. A higher money supply eventually leads to higher inflation because there is more money chasing the same amount of goods and services. Therefore, the foreign exchange objective of the central bank's policy may conflict with its domestic goal of price stability.
