A system of fixed exchange rates is more likely to result in exchange controls than is a system of flexible (floating)exchange rates.

Fixed Exchange Rates

A currency system where the value of a currency is set at a predetermined rate relative to other currencies, instead of fluctuating in the open market.

Exchange Controls

Restrictions that a government may impose over the quantity of foreign currency demand by its citizens and firms and over the rate of exchange as a way to limit the nation’s quantity of outpayments relative to its quantity of inpayments (in order to eliminate a payments deficit).

Flexible Exchange Rates

Foreign exchange system where the value of currencies is determined by supply and demand in the forex market, without direct government intervention.
