When demand for us dollars increase the supply of dollars will decrease and supply of foreign currency will increase as a result the money supply in the country will decrease, to counter such a situation US central bank can devalue the currency in order to curb the excess demand situation in the firex market under fixed exchange rate system.
First of all the demand for dollar rises and the stock of euro
rises as a result demand curve shifts to the right causing an
excess demand situation and shrinkage of money supply in the
domestic US economy.
In order to restore equillibrium the central bank can devalue
dollar under fixed exchange rate system to bring the excess demand
situation under control.
