External debt

1. Meaning, scope and statistical treatment

Gross external debt is the outstanding amount of actual, current and non-contingent liabilities owed by residents to non-residents that require payment of principal and/or interest in the future. Residence refers broadly to an institutional unit's centre of predominant economic interest, rather than its nationality. Consequently, an Indian company borrowing from an overseas bank incurs external debt, while borrowing foreign currency from a resident Indian bank does not automatically create external debt for that company.

The currency of a liability is a separate question. A rupee-denominated bond held by a non-resident can be external debt, even though the borrower need not repay a fixed foreign-currency amount. Conversely, foreign-currency denomination alone does not establish an external liability. Government securities held by non-residents are therefore relevant to external debt statistics.

Debt instruments include loans, debt securities, currency and deposits, trade credit and advances, and other debt liabilities. Special Drawing Rights allocations are recorded as long-term external debt liabilities under international statistical standards. Equity investments and financial derivatives are not included in gross external debt. A guarantee is contingent and generally becomes an actual liability of the guarantor only when called.

• Gross external debt does not subtract residents' external assets.
• Net external debt subtracts corresponding external assets held in debt instruments; it is not identical to the net international investment position.
• The international investment position includes both debt and non-debt financial assets and liabilities.

2. Composition of India's external debt

India's external debt comprises government and non-government borrowing. Important categories include multilateral and bilateral loans, commercial borrowings, non-resident deposits, trade credit and SDR allocations. Government external borrowing supports development and other financing needs, including through institutions such as the World Bank and Asian Development Bank. Private firms and financial institutions also borrow abroad, so total external debt must not be confused with sovereign external debt.

External Commercial Borrowings, or ECBs, are commercial loans raised by eligible resident entities from recognised non-resident lenders under the applicable framework. They can take forms such as bank loans and bonds. Foreign-currency borrowing may offer lower interest rates, but its effective cost includes exchange-rate movements and hedging expenses. Rupee-denominated overseas bonds, commonly called Masala bonds, place the direct currency risk on the investor rather than the issuer.

Non-resident deposit liabilities include relevant balances under schemes such as Foreign Currency Non-Resident Bank, Non-Resident External Rupee and Non-Resident Ordinary Rupee accounts. FCNR(B) deposits are foreign-currency denominated; NRE and NRO accounts are rupee denominated. Their inclusion demonstrates why external debt is not simply synonymous with foreign-currency borrowing.

Trade credit finances international transactions, for example when an overseas supplier allows an Indian importer to pay later. It facilitates commerce but can generate refinancing pressure when global lenders withdraw credit. For examination purposes, distinguish the lender's institutional category, the borrower's sector, currency denomination and maturity: these are different classifications of the same liability.

3. Debt indicators and valuation effects

The external debt-to-GDP ratio compares outstanding external debt with the economy's annual output. It provides a broad measure of scale, but GDP is not a stock of readily available foreign exchange. Debt sustainability also depends on exports, remittances, reserves, interest rates, maturity and the ability of individual borrowers to generate repayment resources.

The debt-service ratio measures principal repayments plus interest payments relative to current external receipts over a period. A higher ratio means more receipts are absorbed by servicing existing liabilities. It differs from debt-to-GDP because debt service is a flow, while outstanding debt is a stock. A country can have a moderate debt stock but face difficulty if large repayments fall due together.

Short-term external debt by original maturity generally covers liabilities with an original maturity of one year or less. Short-term debt by remaining maturity additionally captures longer-term debt falling due within the next year. Remaining maturity is therefore especially useful for identifying near-term rollover needs. Analysts also compare short-term debt with foreign-exchange reserves.

Valuation effects can change reported debt without fresh borrowing. When the US dollar appreciates against other borrowing currencies, the dollar value of debt denominated in those currencies can decline. Separately, rupee depreciation increases the rupee cost of servicing unhedged foreign-currency debt. Thus, a fall in dollar-measured debt need not indicate repayment, and currency changes can affect different measures in different directions.

• Reserves-to-external-debt indicates a liquidity cushion, not a guarantee that every borrower can repay.
• Concessional debt generally offers softer terms, such as lower interest rates, longer maturities or grace periods.
• Currency concentration, floating interest rates and creditor concentration can matter as much as the aggregate debt ratio.

4. Benefits, risks and the balance of payments

External borrowing supplements domestic savings and can finance productive investment, infrastructure and technology imports. Debt is more sustainable when financed projects raise productivity or generate foreign-exchange earnings. Exporters with foreign-currency revenues may possess a natural hedge, although differences in currency, timing and amount can leave residual exposure.

The central risks are currency mismatch, maturity mismatch and refinancing risk. Currency mismatch arises when foreign-currency obligations are serviced from domestic-currency income. Maturity mismatch occurs when short-term borrowing finances long-lived assets. Refinancing, or rollover, risk arises when maturing debt cannot be renewed on affordable terms. Higher global interest rates can raise floating-rate debt-service costs and reduce access to fresh finance.

External debt is a stock measured at a point in time, whereas balance-of-payments transactions are flows during a period. Borrowing and principal repayment are recorded in the financial account under international balance-of-payments terminology; interest payments appear in the current account under primary income. Indian analytical presentations often use capital account more broadly for financial flows.

A current account deficit is not necessarily financed entirely by debt: equity inflows and reserve use can also finance it. Likewise, external debt can rise even without a current account deficit if residents simultaneously accumulate external assets. Changes in the debt stock reflect transactions as well as valuation and other adjustments.

5. India's management framework and examination approach

India manages external borrowing through the Foreign Exchange Management Act, 1999, associated rules and regulations, and RBI directions. The ECB framework specifies matters such as eligible borrowers, recognised lenders, minimum average maturity, permitted end uses, borrowing limits and all-in-cost ceilings. Hedging requirements apply to specified cases rather than uniformly to every external loan. Numerical limits can change, so current RBI directions are preferable to outdated coaching summaries.

Resilience requires prudent borrowing, diversified funding, adequate reserves, credible macroeconomic policies and monitoring of repayment schedules. Reserves provide liquidity during market disruption but are not a substitute for solvent borrowers or productive investment. A government guarantee may improve a borrower's access to finance while transferring potential risk to the public balance sheet.

In Prelims, examine absolute claims carefully: external debt is neither exclusively government debt nor necessarily dollar denominated; all foreign investment is not debt; and a low debt-to-GDP ratio does not eliminate crisis risk. Always ask who owes whom, in which currency, on what terms and when repayment falls due.
