External Sector & Balance of Payments: BPM6, CAD, and FDI versus FPI

The external sector is where India's domestic economy meets the rest of the world, and it is a densely tested corner of the Economy syllabus: eleven real Prelims questions have been built directly on this chapter, spanning exchange rate indices, capital account policy, FDI versus FPI, external debt, Masala Bonds, import cover, and India's trade with its neighbours. Unlike inflation, where the core concepts barely move year to year, this chapter also carries a genuine structural trap: the RBI's own presentation of India's Balance of Payments changed its underlying architecture some years ago, and a statement correct under the old framework is now simply wrong.

This chapter's material overlaps with NCERT Class 12, Introductory Macroeconomics, Chapter 6 (Open Economy Macroeconomics). This note goes further than that chapter's coverage.

From two accounts to three: the BPM6 shift

The Balance of Payments (BoP) is a systematic record of all economic transactions between residents of India and the rest of the world over a period, and the RBI compiles it following the IMF's Balance of Payments and International Investment Position Manual, Sixth Edition (BPM6). This matters because older coaching material, and even older editions of the standard reference texts, still describe a simpler two-way split inherited from the previous manual (BPM5): a Current Account and a Capital Account, the latter a catch-all for everything not current, including FDI, FPI, loans, and the change in reserves.

Under BPM6, that catch-all Capital Account has split into two accounts. The Capital Account now means something much narrower: capital transfers (debt forgiveness, migrants' transfers of capital) and the acquisition or disposal of non-produced, non-financial assets (patents, trademarks, leases), a genuinely small, residual category in India's actual numbers. Everything that used to sit under the old, broader "capital account" label, FDI, portfolio investment (FPI), other investment such as loans and trade credit, financial derivatives, and reserve assets, now lives in a distinct Financial Account. The RBI's own quarterly releases, titled "Developments in India's Balance of Payments during the Quarter," are structured exactly this way: Current Account, Capital Account, Financial Account, and Errors and Omissions as a small balancing residual. Any Prelims statement built on the assumption that "the capital account includes FDI and FPI" is testing the old BPM5 framing, and is the single most likely trap in this chapter.

The Current Account: goods, services, and two kinds of income

The Current Account records transactions in real resources and income, in four components. Trade in goods is the visible, merchandise trade balance, exports minus imports of physical goods, almost always in deficit for India, driven heavily by oil and gold imports. Trade in services is the invisible trade balance, IT and software services, business services, travel, transportation, and this has been India's consistent strength, a healthy surplus that partly offsets the goods deficit. Primary income covers income earned on factors of production held abroad or by foreigners in India: interest, dividends, compensation of employees. Secondary income covers transfers made without anything given in return: private remittances sent home by Indians working abroad, and government grants. The two are not interchangeable, remittances are a secondary income item, not a services export, even though both bring foreign currency in. Reading these four lines together, rather than only the single headline CAD number, is usually what a statement-based question is actually testing.

Current Account Deficit versus Fiscal Deficit: genuinely different things

This is one of the most common conceptual mix-ups in the whole Economy syllabus: the Current Account Deficit (CAD) and the fiscal deficit are unrelated measures of two different things. The fiscal deficit is a domestic public finance concept, the gap between the government's total expenditure and its total receipts other than borrowing, financed through government borrowing, mostly domestic market borrowing via government securities (this site's Budget & Fiscal Deficits note covers it in full). The CAD is an external sector concept: whether India, as a whole economy, is a net borrower from or net lender to the rest of the world, driven by the trade and income flows above, and financed through the Capital and Financial Account, FDI, FPI, external commercial borrowings, NRI deposits, and drawdown of reserves.

A country can run a large fiscal deficit financed almost entirely domestically while carrying only a modest CAD, and the reverse is equally possible. They are not the same number wearing different names, not caused by the same thing, and not financed the same way. Both happen to be conventionally expressed as a percentage of GDP, exactly why exam options like to conflate them.

India's CAD, the real trend

The full-year CAD moderated to USD 23.4 billion (0.6% of GDP) in 2024-25, down from USD 26.1 billion (0.7% of GDP) in 2023-24, per the RBI's own annual release. In 2025-26, the first nine months recorded a CAD of USD 30.1 billion (1% of GDP), down from USD 36.6 billion a year earlier, and the third quarter alone was later revised upward to USD 15.5 billion (1.5% of GDP) from an initial USD 13.2 billion, a reminder that even "final" RBI numbers get revised once fuller Customs data comes in. The fourth quarter then flipped into an actual current account surplus of USD 7.1 billion (0.7% of GDP), bringing the full 2025-26 CAD to USD 25.2 billion (0.6% of GDP). The pattern to hold for the exam is the structure, not the decimal: a persistent, moderate CAD, financed comfortably so far, with services trade and remittances doing the heavy lifting against a chronic merchandise deficit.

FDI versus FPI: a stake in the enterprise versus a stake in the return

Foreign Direct Investment (FDI) is investment that establishes a lasting interest and a genuine say in the management of an Indian enterprise, conventionally a substantial equity stake (the international convention is 10% or more) carrying real influence over decisions, not just a claim on profit. Foreign Portfolio Investment (FPI), the modern, SEBI-regulated successor to what used to be called Foreign Institutional Investment (FII), is investment in listed securities, equities and debt, with no intention of control, purely a return-seeking position. FDI is a non-debt-creating capital flow, distinct from instruments like External Commercial Borrowings that must be repaid regardless of how the business performs, and far harder to reverse quickly, a factory cannot be liquidated the way a shareholding can. FPI, by contrast, can exit in days, which is why it is sometimes called "hot money" and why FDI is treated as the healthier way to finance a CAD.

That difference is not theoretical: in the first nine months of 2025-26, net FDI inflows were a thin USD 3 billion (up from an even thinner USD 0.6 billion a year earlier), while FPI recorded net outflows of USD 4.3 billion, reversing net inflows of USD 9.4 billion the year before. India financed that period's current account gap despite FDI running near-negligible and FPI actively withdrawing money, a live illustration of the exact vulnerability this distinction is meant to flag.

FDI policy: automatic route, government route, and the caps worth knowing

FDI into India flows through one of two routes. Under the automatic route, a foreign investor can bring in FDI up to the sector's prescribed cap without prior government approval, only a post-facto reporting requirement to the RBI under FEMA. Under the government (approval) route, prior approval is required, and this is no longer a single centralised gatekeeper: the Foreign Investment Promotion Board (FIPB) was abolished on 5 June 2017, and approval now sits with the administrative ministry that governs the sector, with DPIIT running the online Foreign Investment Facilitation Portal (FIFP) that receives and routes applications. Eleven sectors, including mining, defence beyond its automatic threshold, broadcasting, telecom in certain cases, civil aviation beyond certain thresholds, and brownfield pharmaceuticals, sit under this route today.

Two sectoral caps are worth holding precisely, since they change often and are a favourite way to test whether a candidate's numbers are current:

• Defence: up to 74% via the automatic route (raised from 49% in September 2020); beyond 74% and up to 100% only through the government route, evaluated case by case, and every defence investment, regardless of route or amount, stays subject to a national security review.
• Insurance: 100% via the automatic route, since the Ministry of Finance's Notification S.O. 2186(E) of 2 May 2026, which followed the Sabka Bima Sabki Raksha (Amendment of Insurance Laws) Act, 2025 (Presidential assent 20 December 2025). The cap had moved from 49% (2015 Act) to 74% (2021) before reaching 100%. It still carries conditions: IRDAI verification, and at least one of the Chairperson, Managing Director, or CEO must be a resident Indian citizen. LIC is a specific carve-out, capped separately at 20%, also via the automatic route.

Treat these figures as correct as of this note's reference date, August 2026, and re-check DPIIT's current Consolidated FDI Policy before an exam, sectoral caps move more often than the route structure around them.

Exchange rate management: a managed float, not a fixed rate

India runs a managed floating exchange rate regime: the rupee's value is primarily set by market demand and supply, but the RBI intervenes, buying or selling US dollars in the spot and forward markets, to curb excessive or disorderly volatility. The precise, testable nuance is what the RBI is not doing: it does not target a specific exchange rate level or a pre-announced band the way a country on a fixed peg would. Its stated objective is orderly market conditions, smoothing the pace of movement, not defending a particular rupee value.

NEER versus REER: the index that inverts on you

The Nominal Effective Exchange Rate (NEER) is a trade-weighted index of the rupee's value against a basket of trading-partner currencies, with no adjustment for inflation; a rising NEER means the rupee is nominally appreciating. The Real Effective Exchange Rate (REER) adjusts the NEER for the inflation differential between India and its trading partners, and this is where the trap sits: a rising REER signals a loss, not an improvement, in trade competitiveness, because Indian goods have become relatively more expensive for foreign buyers once inflation is accounted for. Higher domestic inflation relative to trading partners widens the gap between the two indices. A 2022 Prelims question was built exactly on this reversal, testing whether candidates would wrongly assume a rising REER is good news for exporters.

External debt: composition and the ratios that actually measure risk

India's external debt stood at roughly USD 762.8 billion at end-September 2025, continuing a rising trend from USD 736.3 billion (19.1% of GDP at end-March 2025) to USD 747.2 billion (18.9% of GDP) at end-June 2025. A few structural facts matter more than the headline total:

• Short-term debt (residual maturity basis, debt actually falling due within a year regardless of original tenor) made up 41.6% of total external debt at end-September 2025, up from 40.7% at end-June 2025, and equal to 44.4% of foreign exchange reserves, a ratio worth watching because that debt must be rolled over or repaid within the year, far more exposed to a sudden shift in investor sentiment than long-term debt.
• The debt service ratio (principal plus interest, as a share of current receipts) stood at 5.8% at end-March 2026, down from 6.6% a year earlier, comfortably below levels that would flag vulnerability.
• By currency, the US dollar remains the largest component, at 54.1% of external debt, followed by the Indian rupee itself at 30.4%, a reminder that a meaningful share of what is technically "external" debt carries no direct currency-mismatch risk, since it is rupee-denominated.
• The majority of India's external debt is owed by the private sector, not government or public sector entities, the reverse of what a plausible-sounding wrong option likes to claim.

Foreign exchange reserves and import cover

The RBI publishes reserves weekly in its Weekly Statistical Supplement. Reserves stood at USD 698.2 billion at end-July 2025, split across Foreign Currency Assets (the large majority, USD 588.9 billion), Gold, SDRs, and India's Reserve Tranche Position with the IMF; they have kept climbing since, over USD 716 billion by mid-August 2026, giving India comfortably over ten months of import cover.

Import cover is the number of months' worth of a country's imports its reserves could finance if no fresh foreign exchange came in at all, not a ratio to GDP and not a ratio to exports, the standard wrong options set against it. It is a crisis buffer: the 1991 Balance of Payments crisis is remembered precisely because reserves fell to barely two to three weeks of import cover, exactly why a comfortable double-digit figure today is treated as a genuine marker of resilience, not just a large dollar number in isolation. One further nuance: the change in reserves in nominal terms includes a pure valuation effect from gold prices and bond yields, separate from fresh foreign exchange actually added or drawn down; in 2024-25, reserves rose USD 21.9 billion in nominal terms even though the underlying balance-of-payments-basis change was a fall of USD 5.0 billion.

Masala Bonds: the currency risk sits with the investor

Masala Bonds are rupee-denominated bonds issued by Indian entities, public or private sector borrowers, in overseas markets, falling under the RBI's External Commercial Borrowings framework. The genuinely distinctive, and frequently misstated, feature is where the currency risk sits: because the bond is denominated in rupees but settled in the investor's own currency, if the rupee depreciates between issue and repayment, it is the foreign investor, not the Indian issuer, who absorbs that loss, the exact reverse of a conventional dollar-denominated External Commercial Borrowing, where the Indian issuer bears the exchange risk. That is precisely why encouraging Masala Bond issuance is one of the genuine defensive measures the Government or RBI would use during rupee weakness, tested directly in a 2019 Prelims question: it lets Indian entities raise overseas debt without adding to the country's own foreign-currency debt. The International Finance Corporation, part of the World Bank Group, was among the earliest issuers. An issuer may raise up to a specified annual amount under the automatic route before needing RBI approval, and investors cannot be a related party of the issuer.

India's trade with its South Asian neighbours

Only one Prelims question tests this directly, but it is worth holding precisely rather than skipping, because it shows exactly how UPSC frames it: a statement-based trap built on specific, checkable trade facts, not broad regional geopolitics. Two anchors matter. Textiles and textile articles are a genuinely important item of trade between India and Bangladesh, not an incidental one. And any absolute claim here, "consistently increasing," "largest trading partner every year", is exactly the kind of confident-sounding statement UPSC likes to plant as false: India's trade with Sri Lanka has not risen every single year through the decade, and Nepal has not been India's largest South Asian trading partner in recent years. Treat superlatives in this corner of the syllabus as something to verify, not accept.

Quick revision points

• BPM6 replaced the old BPM5-style two-way Current/Capital split with three accounts: Current Account, a narrow Capital Account (capital transfers, non-produced non-financial assets), and a new Financial Account (FDI, FPI, other investment, reserve assets). Any statement treating "capital account" as including FDI/FPI is using the outdated BPM5 framing.
• CAD and fiscal deficit are unrelated: CAD is external (trade and income flows, financed via the Capital/Financial Account), fiscal deficit is domestic (government expenditure minus non-borrowing receipts, financed via government borrowing).
• India's CAD: 0.6% of GDP in 2024-25 (USD 23.4 billion), a surplus of 0.7% of GDP in Q4 2025-26 (USD 7.1 billion), full-year 2025-26 CAD of 0.6% of GDP (USD 25.2 billion).
• FDI = lasting management stake, non-debt-creating, hard to reverse; FPI (formerly FII) = passive, listed-market portfolio holding, can exit in days.
• FDI routes: automatic (no prior approval, only RBI reporting) versus government (prior approval via the sector's administrative ministry, processed through DPIIT's FIFP since FIPB's abolition in 2017). Defence: 74% automatic, up to 100% via government route. Insurance: 100% automatic (since May 2026); LIC capped separately at 20%.
• India runs a managed float: RBI curbs volatility, it does not target a specific exchange rate level.
• REER rising = competitiveness falling (the reverse of NEER rising, which just means nominal appreciation).
• External debt (end-September 2025): about USD 762.8 billion; short-term debt (residual maturity) is 41.6% of the total; the majority is owed by the private sector, not government.
• Import cover = months of imports reserves could finance, not a ratio to GDP or exports; India currently holds over ten months of cover.
• Masala Bonds: rupee-denominated, issued overseas; currency risk sits with the investor, not the Indian issuer, the opposite of a standard dollar-denominated ECB.

Hold the structural facts as permanent knowledge, and treat every specific number here as something to re-verify against the RBI's and DPIIT's own current releases, since this is the part of the Economy syllabus that goes stale fastest.
