The exchange rate regime is the way a country manages its currency in respect to foreign 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.
The basic types are a floating exchange rate, where the market dictates the movements of the exchange rate, a pegged float, where the central bank keeps the rate from deviating too far from a target band or value, and the fixed exchange rate, which ties the currency to another currency, mostly more widespread currencies such as the U.S. dollar or the euro.
Floating rates are the most common exchange rate regime today. For example, the dollar, euro, yen, and British pound all float. However, since central banks frequently intervene to avoid excessive appreciation/depreciation, these regimes are often called managed float or a dirty float.
Fixed rates are those that have direct convertibility towards another currency. In case of a separate currency, also known as a currency board arrangement, the domestic currency is backed one to one by foreign reserves. A pegged currency with very small bands (<>

A Fixed Exchange Rate
A fixed exchange rate, sometimes called a pegged exchange rate, is a type of exchange rate regime wherein a currency's value is matched to the value of another single currency or to a basket of other currencies, or to another measure of value, such as gold.
A fixed exchange rate is usually used to stabilize the value of a currency, vis-a-vis the currency it is pegged to. This facilitates trade and investments between the two countries, and is especially useful for small economies where external trade forms a large part of their GDP.
It is also used as a means to control inflation. However, as the reference value rises and falls, so does the currency pegged to it. In addition, a fixed exchange rate prevents a government from using domestic monetary policy in order to achieve macroeconomic stability.

A Link Exchange Rate
A linked exchange rate system is a type of exchange rate regime to link the exchange rate of a currency to another. It is the exchange rate system implemented in Hong Kong to stabilise the exchange rate between the Hong Kong dollar (HKD) and the United States dollar (USD). The Macao pataca (MOP) is similarly linked to the Hong Kong dollar.
Unlike a fixed exchange rate system, the government or central bank does not actively interfere in the foreign exchange market by controlling supply and demand of the currency in order to influence the exchange rate. The exchange rate is stabilised by a mechanism.

A Floating Exchange Rate
A floating exchange rate or a flexible exchange rate is a type of exchange rate regime wherein a currency's value is allowed to fluctuate according to the foreign exchange market. A currency that uses a floating exchange rate is known as a floating currency. The opposite of a floating exchange rate is a fixed exchange rate.
There are economists who think that, in most circumstances, floating exchange rates are preferable to fixed exchange rates. As floating exchange rates automatically adjust, they enable a country to: dampen the impact of shocks and foreign business cycles, and to preempt the possibility of having a balance of payments crisis.
However, in certain situations, fixed exchange rates may be preferable for their greater stability and certainty. This may not necessarily be true, considering the results of countries that attempt to keep the prices of their currency "strong" or "high" relative to others, such as the UK or the Southeast Asia countries before the Asian currency crisis.
The debate of making a choice between fixed and floating exchange rate regimes is set forth by Mundell-Fleming model, which argues that an economy cannot simultaneously maintain a fixed exchange rate, free capital movement, and an independent monetary policy. It can choose any two for control, and leave third to the market forces.
In cases of extreme appreciation or depreciation, a central bank will normally intervene to stabilize the currency. Thus, the exchange rate regimes of floating currencies may more technically be known as a managed float. A central bank might, for instance, allow a currency price to float freely between an upper and lower bound, a price "ceiling" and "floor".
Management by the central bank may take the form of buying or selling large lots in order to provide price support or resistance, or, in the case of some national currencies, there may be legal penalties for trading outside these bounds.

The Exchange Rate
The exchange rates (also known as the foreign-exchange rate, forex rate or FX rate) between two currencies specifies how much one currency is worth in terms of the other. It is the value of a foreign nation’s currency in terms of the home nation’s currency.
For example an exchange rate of 102 Japanese yen (JPY, ¥) to the United States dollar (USD, $) means that JPY 102 is worth the same as USD 1. The foreign exchange market is one of the largest markets in the world. By some estimates, about 3.2 trillion USD worth of currency changes hands every day.
The spot exchange rate refers to the current exchange rate. The forward exchange rate refers to an exchange rate that is quoted and traded today but for delivery and payment on a specific future date.

The Currency Band
The currency band is a system of exchange rates by which a floating currency is backed by hard money.
A country selects a range, or "band", of values at which to set their currency, and returns to a fixed exchange rate if the value of their currency shifts outside this band. This allows for some revaluation, but tends to stabilize the currency's value within the band. In this sense, it is a compromise between a fixed (or "pegged") exchange rate and a floating exchange rate.
For example, the exchange rate of the renminbi of the mainland of the People's Republic of China has recently been based upon a currency band; the European Economic Community's "snake in the tunnel" was a similar concept that failed, but ultimately led to the establishment of the European Exchange Rate Mechanism (ERM) and ultimately the Euro.
