A fixed currency regime, also known as a pegged exchange rate system, is a type of exchange rate system in which a country's currency is pegged or fixed to the value of another currency or a basket of currencies. Under a fixed currency regime, the central bank of the country will buy or sell its own currency in the foreign exchange market in order to maintain the fixed exchange rate.

Some examples of countries with fixed currency regimes include:

• Hong Kong: The Hong Kong dollar is pegged to the U.S. dollar at a rate of approximately 7.75 Hong Kong dollars to 1 U.S. dollar. The Hong Kong Monetary Authority (HKMA) is responsible for maintaining the peg through intervention in the foreign exchange market.
• China: The Chinese renminbi is pegged to a basket of currencies, with the U.S. dollar being the most important component of the basket. The People's Bank of China (PBOC) is responsible for maintaining the peg through intervention in the foreign exchange market.
• Saudi Arabia: The Saudi riyal is pegged to the U.S. dollar at a rate of 3.75 riyals to 1 U.S. dollar. The Saudi Arabian Monetary Authority (SAMA) is responsible for maintaining the peg through intervention in the foreign exchange market.
• Kuwait: The Kuwaiti dinar is pegged to a basket of currencies, with the U.S. dollar being the most important component of the basket. The Central Bank of Kuwait is responsible for maintaining the peg through intervention in the foreign exchange market.
• Bahrain: The Bahraini dinar is pegged to the U.S. dollar at a rate of approximately 0.38 dinars to 1 U.S. dollar. The Central Bank of Bahrain is responsible for maintaining the peg through intervention in the foreign exchange market.
