Foreign exchange rate

Balance of payments model

The balance of payments model holds that foreign exchange rates are at an equilibrium level if they produce a stable Current account (balance of payments)current account balance. A nation with a trade deficit will experience a reduction in its foreign exchange reserves, which ultimately lowers (depreciates) the value of its currency. A cheaper (undervalued) currency renders the nation's goods (exports) more affordable in the global market while making imports more expensive. After an intermediate period, imports will be forced down and exports to rise, thus stabilizing the trade balance and bring the currency towards equilibrium.
