FIGURE 18.7 Impact of a Competitive Devaluation on the Foreign Exchange Market and on the
Central Bank Balance Sheet
Starting from equilibrium on the foreign exchange market at Ef0, the central bank announces a
new peg corresponding to a higher price for the foreign currency, Ef1. The central bank achieves
this higher price by purchasing the foreign currency on the foreign exchange market, thus
reducing its supply on the market. As central bank foreign reserves increase, so does the money
supply.
