What is Currency Peg?

Overview

A currency peg is a monetary policy tool used by countries to maintain a fixed exchange rate between their currency and another major currency, such as the US dollar or the euro. This means that the value of the pegged currency is tied to the value of the reference currency, which can help reduce fluctuations in exchange rates. By doing so, countries aim to provide more stability in their economy, making it easier for businesses and investors to plan for the future. The way a currency peg works is that the central bank of the country will buy or sell its own currency in the foreign exchange market to maintain the desired exchange rate. For instance, if a country pegs its currency to the US dollar and the dollar strengthens, the central bank will sell its foreign reserves to prevent its currency from losing value. This requires the country to have sufficient foreign reserves to support the peg, which can be a challenge during economic downturns. One real-world example of a currency peg is the Hong Kong dollar, which is pegged to the US dollar at a rate of approximately 7.8 HKD to 1 USD. This peg has helped maintain stability in Hong Kong's economy, especially during times of financial uncertainty. However, maintaining a currency peg can also limit a country's monetary policy flexibility, as it must prioritize the peg over other economic goals.
