Question

Quizplus · Accepted Answer

A balance of payments surplus means that there is an excess of inflows of foreign currency into the country compared to outflows. In a fixed exchange-rate system, the central bank must buy up any excess supply of its own currency to maintain the fixed exchange rate, which means that the quantity supplied of its currency on the international money market will exceed the quantity demanded, and there will be an accumulation of foreign currencies in the country.
