currency of intervention

The term "currency of intervention" refers to a currency used by monetary authorities to stabilize their own currency's exchange rate in the foreign exchange market. This practice was a key component of the International Monetary Fund (IMF) system of pegged exchange rates established after World War II.123

Under this system, countries registered a legal gold valuation for their currency with the IMF, establishing parities of exchange. If a currency was in short supply in a market, the country's authorities were obligated to supply that currency to keep its price from rising above the agreed-upon limit. The U.S. dollar often served as this "currency of intervention".123

Central banks also play a crucial role in managing a nation's money supply, the cost of credit, and the foreign exchange value of its currency, aiming for stable prices and high employment. They intervene in foreign exchange markets to stabilize their currency's value.45
