This document discusses the balance of payments (BOP) of a country. It defines BOP as a systematic record of all economic transactions between a country and the rest of the world over a period of time, usually annually. It notes that the BOP has two components - the current account, which covers visible and invisible trade, and the capital account, which covers financial transactions like investments. A country experiences a BOP surplus if it receives more foreign currency than it spends, and a deficit if it spends more than it receives. It also discusses factors that can cause BOP disequilibria and measures governments can take to address BOP deficits.
