The type of exchange rate regime a country has can impact its economic growth. A study looked at 60 countries from 1973-1998 and found that exchange rate regimes with a monetary policy anchor, like pegged, intermediate, or flexible, tend to help economic growth. On the other hand, exchange rate regimes without a monetary policy anchor can be harmful for growth. This means that having a clear monetary policy framework alongside the exchange rate arrangement is crucial for a country's economic performance.
