Currency governments intervene in the market to buy or sell their currency to balance supply and demand at a static exchange rate. In cases where a country has control of its own currency, that control is exercised either by a central bank or by a Ministry of Finance.

A monetary authority is created and supported by its sponsoring government, so independence can be reduced by the legislative or executive authority that creates it.
