Continual surpluses on the current account of the balanced balance of payments is undesirable as it highlights that a country is not using its reserves of foreign currency in order to enjoy fully the imports it can afford therefore welfare is unlikely to be maximised. Furthermore, if one country has a surplus in their balanced balance of payments current account this means another country will have a deficit; in which they will take action to remove this deficit leading to a reduction in the volume of international trade.
