linked 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.
