Fully fixed exchange rates

In a fixed exchange rate system, the government (or the central bank acting on its behalf) intervenes in the currency market in order to keep the exchange rate close to a fixed target. It is committed to a single fixed exchange rate and does not allow major fluctuations from this central rate.

Semi-fixed exchange rates

Currency can move inside permitted ranges of fluctuation. The exchange rate is the dominant target of economic policy-making, interest rates are set to meet the target and the exchange rate is given a specific target.

Free floating

The value of the currency is determined solely by market supply and demand forces in the foreign exchange market. Trade flows and capital flows are the main factors affecting the exchange rate. A floating exchange rate system: Monetary system in which exchange rates are allowed to move due to market forces without intervention by national governments. For example, the Bank of England does not actively intervene in the currency markets to achieve a desired exchange rate level. With floating exchange rates, changes in market demand and supply cause a currency to change in value. Pure free floating exchange rates are rare - most governments at one time or another seek to "manage" the value of their currency through changes in interest rates and other controls.
