Exchange rate regime
An exchange rate regime is the way a monetary authority of a country or currency union manages the currency in relation to 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, elasticity of the labor market, financial market development, capital mobility etc.
There are two major regime types:
- fixed (or pegged) exchange rate regimes, where the currency is tied to another currency, mostly reserve currencies such as the U.S. dollar or the euro or the British Pound Sterling or a basket of currencies, or
- floating (or flexible) exchange rate regimes, where the economy dictates movements in the exchange rate.
There are also intermediate exchange rate regimes that combine elements of the other regimes.
This classification of exchange rate regime is based on the classification method carried out by GGOW (Ghos, Guide, Ostry and Wolf, 1995, 1997), which combined the IMF de jure classification with the actual exchange behavior so as to differentiate between official and actual policies. The GGOW classification method is also called Trichotomy Method.
Floating exchange rate regime
A floating (or flexible) exchange rate regime is one in which a country's exchange rate fluctuates in a wider range and the country's monetary authority makes no attempt to fix it against any base currency. A movement in the exchange is either an appreciation or depreciation.
Free float, also known as clean float, signifies that a currency's value is allowed to fluctuate in response to foreign-exchange market mechanisms without government intervention.
Managed float (or dirty float)
Managed float, also known as dirty float, involves government intervention in the market exchange rate in different forms and degrees, in an attempt to make the exchange rate change in a direction conducive to the economic development of the country, especially during an extreme appreciation or depreciation.
A monetary authority may, for example, allow the exchange rate to float freely between an upper and lower bound, a price "ceiling" and "floor".
Intermediate rate regime
The exchange rate regimes between the fixed ones and the floating ones.
There is only a tiny variation around the fixed exchange rate against another currency, well within plus or minus 2%.
For example, Denmark has fixed its exchange rate against the euro, keeping it very close to 7.44 krone = 1 euro (0.134 euro = 1 krone).
A crawling peg is when a currency steadily depreciates or appreciates at an almost constant rate against another currency, with the exchange rate following a simple trend.
Some variation about the rate is allowed, and adjusted as above.
Currency basket peg
A currency basket is a portfolio of selected currencies with different weightings. The currency basket peg is commonly used to minimize the risk of currency fluctuations. For example, Kuwait shifted the peg based on a currency basket consists of currencies of its major trade and financial partners.
Fixed exchange rate regime
A fixed exchange rate regime, sometimes called a pegged exchange rate regime, is one in which a monetary authority pegs its currency's exchange rate to another currency, a basket of other currencies or to another measure of value (such as gold), and may allow the rate to fluctuate within a narrow range. To maintain the exchange rate within that range, a country's monetary authority usually needs to intervenes in the foreign exchange market. A movement in the peg rate is called either revaluation or devaluation.
Currency board is an exchange rate regime in which a country's exchange rate maintain a fixed exchange rate with a foreign currency, based on an explicit legislative commitment. It is a type of fixed regime that has special legal and procedural rules designed to make the peg "harder—that is, more durable". Examples include the Hong Kong dollar against the U.S dollar and Bulgarian lev against the Euro.
Dollarisation, also currency substitution, means a country unilaterally adopts the currency of another country.
Most of the adopting countries are too small to afford the cost of running its own central bank or issuing its own currency. Most of these economies use the U.S dollar, but other popular choices include the euro, and the Australian and New Zealand dollars.
A currency union, also known as monetary union, is an exchange regime where two or more countries use the same currency. Under a currency union, there is some form of transnational structure such as a single central bank or monetary authority that is accountable to the member states.
Examples of currency unions are the Eurozone, CFA and CFP franc zones. One of the first known examples is the Latin Monetary Union that existed between 1865 and 1927. The Scandinavian Monetary Union existed between 1873 and 1905.
