The balance of payments is a double-entry system that records all economic transactions between a country's residents and the rest of the world within a given period. It includes exports and imports of both visible items (goods) and invisible items (services, capital). The current account tracks trade balances as well as receipts and payments for services and transfers, while the capital account tracks foreign investment, loans, banking capital, and other financial flows. India's balance of payments was positive in early plans but turned negative in the 1980s and 1990s due to liberalized imports, Gulf wars, industrialization, and currency issues before becoming positive again in recent years.
