Balance of Payments

The balance of payments is an accounting framework before it is anything else. Every transaction has two sides, and the two accounts sum to zero by construction. That makes it easy to misread: there is no such thing as a BOP 'crisis' in the accounting -- crises show up in the composition of financing and in stocks of external debt, not in the headline sum.

The economic content comes from asking what kind of capital is financing the current account and whether that financing is sustainable. Short-term debt financing a consumption boom is a different problem from long-term FDI financing productive investment, even if both produce the same headline deficit.

The balance of payments is a systematic record of all economic transactions between a country's residents and the rest of the world over a given period. It is organized into two main accounts. The current account captures trade in goods and services, income flows, and unilateral transfers. The capital and financial account records cross-border investment, loans, and reserve movements.

By accounting identity, the two accounts always sum to zero. A current account deficit means capital is flowing in to finance it -- the country is borrowing from the world, importing real resources, or running down foreign assets. The policy read depends on the reason for the deficit and the way it is financed.
