External sector — Balance of Payments, forex & exchange rate

Balance of Payments is the systematic record of economic transactions between residents of India and non-residents during a period. It is a flow statement, not a stock statement; it records transactions, while the International Investment Position records external assets and liabilities at a point in time.

• Core definition: BoP covers goods, services, income, transfers, financial claims, liabilities, monetary gold, SDRs and reserve changes involving residents and non-residents.
• Accounting logic: every transaction has two entries; conceptually BoP balances, but in practice a separate errors and omissions item absorbs timing, valuation and reporting gaps.
• Current account: records goods, services, primary income and secondary income. A current account deficit means domestic absorption exceeds domestic production plus net income and transfers from abroad.
• Capital and financial side: in Indian public discussion, “capital account” often covers investment flows, external borrowing, banking capital and reserve changes; IMF terminology separately identifies capital account and financial account.
• Constitutional base: Article 246 gives Parliament power over Union List subjects; Seventh Schedule List I Entry 36 covers currency, legal tender and foreign exchange; Entry 37 covers foreign loans; Entry 38 covers RBI; Entry 41 covers foreign trade and customs frontiers.
• Treaty and trade link: Article 253 enables Parliament to legislate for international agreements; Article 286 restricts State taxation on supplies in the course of import or export.
• Statutory base: the Reserve Bank of India Act, 1934 underpins RBI’s central banking and reserve functions; FEMA, 1999 replaced the criminal-control approach of FERA with management of foreign exchange. Section 40 of the RBI Act concerns RBI transactions in foreign exchange under the central government framework and IMF obligations.
• Tax and customs link: Article 265 requires authority of law for taxation, while Union List Entry 83 supports customs duties. Therefore trade flows, customs revenue and external-sector policy meet in the Union domain.
• Prelims trap: BoP is broader than balance of trade. Trade balance covers visible merchandise exports and imports; BoP includes services, remittances, investment income, borrowing, foreign investment and reserves.
• Development link: external stability protects inflation, energy security, import capacity, employment in export sectors, fiscal space and poverty-reduction programmes that depend on affordable imported inputs.
• Source discipline: RBI publishes quarterly external-sector data; Economic Survey summarises annual trends; Ministry of Commerce gives trade data, but final BoP classification belongs to RBI methodology.
• Exam priority: first separate current-account items from capital/financial flows, then connect CAD financing with exchange-rate pressure, reserve movement and macro-policy choices.
