• Current Account: It shows export and import of visibles (also called merchandise or goods - represent trade balance) and invisibles (also called non-merchandise). Invisibles include services, transfers and income.
• Capital Account: It shows a capital expenditure and income for a country. It gives a summary of the net flow of both private and public investment into an economy. External Commercial Borrowing (ECB), Foreign Direct Investment, Foreign Portfolio Investment, etc form a part of capital account.
• Errors and Omissions: Sometimes the balance of payments does not balance. This imbalance is shown in the BoP as errors and omissions. It reflects the country’s inability to record all international transactions accurately.
• Changes in Foreign Exchange Reserves: Movements in the reserves comprises changes in the foreign currency assets held by the Reserve Bank of India (RBI) and also in Special Drawing Rights (SDR) balances.
