The balance of payments, a fundamental concept in international economics, measures a country's financial transactions—such as imports, exports, investments, and transfers—over a specific period. It consists of three main accounts: the current account (covering trade and income), the financial account (tracking changes in asset ownership), and the capital account (dealing with transfers of non-produced assets). Historically, from the mercantilist emphasis on accumulating gold to the current use of flexible exchange rates, the concept has evolved, reflecting changing economic ideologies.
Scholars such as Ferdinand Marcos connected it to national policy pressures, while Henry Warren and John Stuart Mill analyzed its workings in banking and commerce. William Amasa Scott highlighted its practical function in finance, demonstrating how disparities are addressed. Bringing these viewpoints together, the balance of payments continues to serve both as a technical record and an indicator of global economic interconnectedness.
