Fixed exchange rate systemA fixed exchange rate, often called a pegged exchange rate, is a type of exchange rate regime in which a currency's value is fixed or pegged by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold. There are benefits and risks to using a fixed exchange rate system. A fixed exchange rate is typically used to stabilize the exchange rate of a currency by directly fixing its value in a predetermined ratio to a different, more stable, or more internationally prevalent currency (or currencies) to which the currency is pegged.
Managed float regimeManaged float regime is an international financial environment in which exchange rates fluctuate from day to day, but central banks attempt to influence their countries' exchange rates by buying and selling currencies to maintain a certain range. The peg used is known as a crawling peg. In an increasingly integrated world economy, the currency rates impact any given country's economy through the trade balance. In this aspect, almost all currencies are managed since central banks or governments intervene to influence the value of their currencies.
Currency boardIn public finance, a currency board is a monetary authority which is required to maintain a fixed exchange rate with a foreign currency. This policy objective requires the conventional objectives of a central bank to be subordinated to the exchange rate target. In colonial administration, currency boards were popular because of the advantages of printing appropriate denominations for local conditions, and it also benefited the colony with the seigniorage revenue.
Foreign exchange reservesForeign exchange reserves (also called forex reserves or FX reserves) are cash and other reserve assets such as gold held by a central bank or other monetary authority that are primarily available to balance payments of the country, influence the foreign exchange rate of its currency, and to maintain confidence in financial markets. Reserves are held in one or more reserve currencies, nowadays mostly the United States dollar and to a lesser extent the euro.
Exchange rate regimeAn exchange rate regime is a way a monetary authority of a country or currency union manages the currency about other currencies and the foreign exchange market. It is closely related to monetary policy and the two are generally dependent on many of the same factors, such as economic scale and openness, inflation rate, the elasticity of the labor market, financial market development, and capital mobility. There are two major regime types: Floating (or flexible) exchange rate regime exist where exchange rates are determined solely by market forces and often manipulated by open-market operations.
Exchange rateIn finance, an exchange rate is the rate at which one currency will be exchanged for another currency. Currencies are most commonly national currencies, but may be sub-national as in the case of Hong Kong or supra-national as in the case of the euro. The exchange rate is also regarded as the value of one country's currency in relation to another currency. For example, an interbank exchange rate of 131 Japanese yen to the United States dollar means that ¥131 will be exchanged for or that will be exchanged for ¥131.
United States dollarThe United States dollar (symbol: ;currencycode:USD;alsoabbreviatedUS to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. Foreign exchange marketThe foreign exchange market (forex, FX, or currency market) is a global decentralized or over-the-counter (OTC) market for the trading of currencies. This market determines foreign exchange rates for every currency. It includes all aspects of buying, selling and exchanging currencies at current or determined prices. In terms of trading volume, it is by far the largest market in the world, followed by the credit market. The main participants in this market are the larger international banks.
Currency substitutionCurrency substitution is the use of a foreign currency in parallel to or instead of a domestic currency. The process is also known as dollarization or euroization when the foreign currency is the dollar or the euro, respectively. Currency substitution can be full or partial. Full currency substitution can occur after a major economic crisis, such as in Ecuador, El Salvador, and Zimbabwe. Some small economies, for whom it is impractical to maintain an independent currency, use the currencies of their larger neighbours; for example, Liechtenstein uses the Swiss franc.
Monetary policyMonetary policy is the policy adopted by the monetary authority of a nation to affect monetary and other financial conditions to accomplish broader objectives like high employment and price stability (normally interpreted as a low and stable rate of inflation). Further purposes of a monetary policy may be to contribute to economic stability or to maintain predictable exchange rates with other currencies.
