Currency Peg

A currency peg, also known as a fixed exchange rate, is a system where a country's currency is tied to the value of another currency, usually the U.S. dollar or a basket of currencies. The pegging country’s central bank maintains the exchange rate within a specific range by buying or selling its own currency in foreign exchange markets. Currency pegs are used to stabilize exchange rates and promote trade by reducing currency volatility.

Example

The Hong Kong dollar is pegged to the U.S. dollar, with the Hong Kong Monetary Authority maintaining the exchange rate around 7.80 HKD per USD.
