Current account (balance of payments)

The current account is defined by the International Monetary Fund (IMF) as the sum of the balance of trade in goods and services, net primary income (earnings on foreign investments minus payments to foreign investors), and net secondary income (current transfers such as remittances and foreign aid).¹ It is a flow variable, measured over a period (typically a quarter or year), and contrasts with the capital account, which records asset transfers and acquisition/disposal of non-produced, non-financial assets.

In practice, the current account balance equals the difference between national saving and domestic investment. A surplus implies that a country saves more than it invests, lending the excess to the rest of the world; a deficit implies the opposite.²

National statistical agencies compile current account data following the IMF's Balance of Payments and International Investment Position Manual (BPM6).¹ The U.S. Bureau of Economic Analysis (BEA) publishes quarterly data, while the IMF provides global aggregates in its World Economic Outlook.³

Data are subject to revisions and asymmetries: for instance, the global sum of current account balances is not zero due to measurement errors, but the IMF estimates that the global current account surplus (sum of surpluses) reached about $2.1 trillion in 2022, reflecting large surpluses in China, Germany, and oil exporters.³

The current account balance is a crucial indicator of external sustainability and international competitiveness. Persistent deficits may signal an economy living beyond its means, but they can also reflect attractive investment opportunities that draw foreign capital.² Conversely, persistent surpluses can indicate undervalued currencies or insufficient domestic demand.

Economists debate the policy implications. The IMF has called for reducing global imbalances to foster stability, while some argue that deficits are benign if financed by productive investment.³ The U.S. current account deficit, for example, has been a recurring policy concern, though it has narrowed from over 6% of GDP in 2006 to about 0.5% in 2023.

Current account imbalances have varied widely across time and countries. The United Kingdom ran persistent surpluses during the 19th century as the world's banker, while the United States shifted from a surplus after World War II to a chronic deficit from the 1980s onward.⁴ Germany and Japan have maintained large surpluses in recent decades, while emerging economies like Brazil and India have often run deficits.

Oil price shocks, demographic shifts, and exchange rate regimes all influence these patterns. For instance, the 2014 oil price collapse turned many oil-exporting countries' surpluses into deficits, illustrating the sensitivity of the current account to commodity prices.³

Beyond the headline numbers, the current account includes several subtle features. The distinction between primary and secondary income matters: remittances, a secondary income component, exceed foreign aid in many developing countries and can be a stabilizing force.¹ Also, the current account is closely linked to the net international investment position (NIIP), as cumulative deficits reduce a country's net foreign assets.

An often-overlooked point is that the current account is not always a reliable gauge of economic health. For example, a country can run a deficit while experiencing strong growth if it is importing capital goods for investment. Moreover, the U.S. current account deficit is partly offset by the 'exorbitant privilege' of the dollar, which allows it to borrow cheaply in its own currency.⁴
