The current account balance is the sum of net trade in goods and services, net earnings from cross-border investments, and net transfer payments. It reflects a country's economic transactions with the rest of the world and is a fundamental component of the balance of payments. A surplus indicates that a country exports more than it imports, while a deficit shows the opposite.

Gross National Income (GNI) measures a country's total income. It encompasses income earned by residents, businesses, and foreign sources, defined as employee compensation and investment profits. GNI adds product taxes not included elsewhere and subtracts subsidies. It accounts for income from residents working abroad but excludes earnings from foreigners within the country.

A negative value for Net Foreign Direct Investment indicates a country is a net receiver of investments, as foreign inflows exceed outflows after Balance of Payments adjustments. A positive value indicates a net provider, with outflows exceeding inflows. Inflows are credits (increasing foreign claims on domestic assets), while outflows are debits (increasing domestic assets abroad).

Foreign direct investment (FDI, net inflows) shows how much capital foreign investors bring into a country after accounting for any funds that flow back in the opposite direction. It represents the net value of overseas companies establishing, expanding, or financing businesses in the reporting country. A positive number means more capital entered the country than was withdrawn, while a negative number means foreign investors pulled out more than they invested.

Foreign direct investment (FDI, net outflows) shows how much capital residents of a country invest abroad after accounting for any funds that flow back in the opposite direction. It represents the net value of domestic companies establishing, expanding, or financing businesses in other countries. A positive number means more capital was invested abroad than withdrawn, while a negative number means residents pulled back more than they invested.

Principal and interest payments to the IMF in currency, goods, or services on long-term debt expressed as a share of GNI.

Formerly gross domestic investment, gross capital formation measures the share of a country’s economic output invested in fixed assets, including buildings, machinery, and infrastructure. It indicates how much of the economy is devoted to building productive capacity.
