In macroeconomics and international finance, a country's current account records the value of exports and imports of both goods and services and international transfers of capital. It is one of the two components of the balance of payments, the other being the capital account (also known as the financial account). Current account measures the nation's earnings and spendings abroad and it consists of the balance of trade, net primary income or factor income (earnings on foreign investments minus payments made to foreign investors) and net unilateral transfers, that have taken place over a given period of time. The current account balance is one of two major measures of a country's foreign trade (the other being the net capital outflow). A current account surplus indicates that the value of a country's net foreign assets (i.e. assets less liabilities) grew over the period in question, and a current account deficit indicates that it shrank. Both government and private payments are included in the calculation. It is called the current account because goods and services are generally consumed in the current period.

The current account is an important indicator of an economy's external sector. It is defined as the sum of the balance of trade (goods and services exports minus imports), net income from abroad, and net current transfers. A positive current account balance indicates the nation is a net lender to the rest of the world, while a negative current account balance indicates that it is a net borrower from the rest of the world. A current account surplus increases a nation's net foreign assets by the amount of the surplus, and a current account deficit decreases it by that amount.

A country's balance of trade is the net or difference between the country's exports of goods and services and its imports of goods and services, excluding all financial transfers, investments and other components, over a given period of time. A country is said to have a trade surplus if its exports exceed its imports, and a trade deficit if its imports exceed its exports.

Positive net sales abroad generally contribute to a current account surplus; negative net sales abroad generally contribute to a current account deficit. Because exports generate positive net sales, and because the trade balance is typically the largest component of the current account, a current account surplus is usually associated with positive net exports.

In the net factor income or income account, income payments are outflows, and income receipts are inflows. Income are receipts from investments made abroad (note: investments are recorded in the capital account but income from investments is recorded in the current account) and money sent by individuals working abroad, known as remittances, to their families back home. If the income account is negative, the country is paying more than it is taking in interest, dividends, etc.

The various subcategories in the income account are linked to specific respective subcategories in the capital account, as income is often composed of factor payments from the ownership of capital (assets) or the negative capital (debts) abroad. From the capital account, economists and central banks determine implied rates of return on the different types of capital. The United States, for example, gleans a substantially larger rate of return from foreign capital than foreigners do from owning United States capital.

In the traditional accounting of balance of payments, the current account equals the change in net foreign assets. A current account deficit implies a reduction of net foreign assets:

$${\displaystyle {\text{Current account}}={\text{change in net foreign assets}}.}$$
