Introduction

India's external borrowing framework governs how the government, corporates, and financial institutions raise funds from abroad. It covers sovereign debt owed to official creditors (multilateral and bilateral), commercial external debt, and market instruments like External Commercial Borrowings (ECBs) and rupee-denominated Masala bonds. Managing external debt sustainably — avoiding currency and rollover risk while financing development — is a core challenge for India's economic managers.

India's External Debt: Composition and Recent Trends

India's total external debt stood at approximately $717 billion at end-March 2025, rising from around $650 billion at end-March 2024. The debt-to-GDP ratio rose to 19.1% at end-March 2025, up from 18.5% a year earlier, driven by faster growth in external debt (+13% in INR terms) relative to nominal GDP growth (+9.8%).

Composition by Creditor Type

Category Nature
Government (Sovereign) debt Borrowings from multilateral institutions (World Bank, ADB, IMF) and bilateral creditors (Japan, USA, Germany) — entirely from official sources
Non-government / Commercial ECBs, NRI deposits, short-term trade credits, bonds/debentures
NRI deposits FCNR(B), NRE, NRO accounts — significant volatile component

The $67.5 billion increase in external debt during FY2024-25 was primarily driven by commercial borrowings (+$41.2 billion), followed by NRI deposits (+$12.8 billion), short-term debt (+$6.9 billion), bilateral debt (+$3.9 billion), and multilateral debt (+$2.5 billion).

Key debt sustainability indicator: India's debt service ratio (principal + interest as % of current receipts) was 6.6% at end-March 2025 — moderate and manageable. Sovereign external debt constitutes only about 5% of total Union government liabilities, with 95% being domestic-currency denominated — limiting currency risk.

External Commercial Borrowings (ECB)

ECBs are commercial loans raised by eligible Indian entities from recognized non-resident lenders for minimum average maturities prescribed by the RBI.

Two Routes

Feature Automatic Route Approval Route
RBI permission Not required — processed by Authorised Dealer (AD) Category-I Banks Prior RBI approval required
Eligible borrowers Most corporates, NBFC-IFC, NBFC-MFI, infrastructure companies Cases not covered under automatic route; specific sectors
Annual limit Up to USD 1.5 billion per financial year per borrower Assessed case-by-case

Key ECB Parameters (as at 2025)

  • Minimum Average Maturity Period (MAMP): 3 years for most borrowers (10 years for certain sectors like infrastructure)
  • End-use restrictions: ECBs cannot be used for real estate (other than affordable housing), capital market investment, or equity investment domestically
  • All-in-cost ceiling: RBI prescribes maximum interest + fees payable to the overseas lender (expressed as benchmark rate + spread)
  • Liability-equity ratio: For FCY-denominated ECB from a direct foreign equity holder — cannot exceed 7:1

In October 2025, RBI issued draft amendments proposing significant liberalisation of the ECB framework, including rationalisation of end-use restrictions and simplification of reporting requirements.

Masala Bonds

Masala bonds are rupee-denominated bonds issued by Indian entities to investors outside India. The key distinguishing feature: currency risk lies with the investor, not the issuer, unlike conventional foreign currency bonds. This makes them attractive for India's borrowers since they eliminate exchange rate risk on repayment.

Key Features

Parameter Detail
Framework introduced RBI circular September 2015; liberalised April 2016
Minimum maturity 3 years
Annual limit (automatic route) INR 50 billion per entity per financial year
Eligible issuers Indian corporates, REITs, InvITs; Banks and NBFCs also permitted
Currency risk Borne by overseas investor — INR-denominated coupon and principal

Notable issuances: HDFC Bank, NHB, NTPC, and the International Finance Corporation (IFC) issued the first-ever Masala bond in 2014 before RBI formalised the framework.

India's Sovereign Green Bonds

India issued its first-ever Sovereign Green Bonds in January–February 2023, becoming one of a select group of sovereign issuers to do so.

Parameter Detail
First issuance date 25 January 2023
Second tranche 9 February 2023
Total amount raised INR 160 billion (~USD 2 billion)
Instruments 5-year bonds (coupon 7.10%) + 10-year bonds (coupon 7.29%)
Proceeds use Financing government expenditure in renewable energy, clean transportation, green buildings, sustainable water management
RBI role Allowed investments to count towards SLR; permitted FPI investment beyond normal limits as an incentive

The bonds attracted over-subscription, with bids worth more than four times the issue size — signalling strong investor appetite for ESG-linked sovereign instruments from India.

FRBM Act and Debt Targets

The Fiscal Responsibility and Budget Management (FRBM) Act, 2003 provides the legislative framework for fiscal consolidation and debt management. Key targets under the Act:

  • Fiscal deficit: Central government to limit to 3% of GDP
  • Central government debt: Not to exceed 40% of GDP
  • General government (Centre + States) debt: Target of 60% of GDP (set under 2018 amendment, to be achieved by 2024-25)

India's sovereign external debt (from official creditors) is entirely excluded from volatile market borrowings — a structural strength. However, India has consistently used the escape clause (allowing temporary deviation in exceptional circumstances) in recent years due to COVID-19, global shocks, and infrastructure push.

IMF Debt Sustainability Analysis (DSA) Framework

The IMF's DSA assesses whether a country's public and external debt is sustainable over the medium term. Key components:

Indicator What It Measures
Debt-to-GDP ratio Stock of debt relative to economic output
Gross financing needs (GFN) Annual borrowing required to refinance maturing debt + fiscal deficit
Debt service-to-revenue ratio Repayment burden relative to government revenue
External debt-to-exports ratio Solvency indicator: how many years of exports to repay external debt
Debt service-to-exports ratio Liquidity indicator: annual drain on foreign exchange

India's external debt profile is considered moderate risk — the debt-to-GDP ratio at ~19% is well below the 40%–60% range seen in high-risk emerging markets. The large share of long-term concessional official debt keeps rollover risk low.

Exam Strategy

For Prelims: Know the ECB automatic route limit (USD 1.5 billion/year), Masala bond key feature (rupee-denominated; currency risk with investor), India's first sovereign green bond year (January 2023, ~USD 2 billion), external debt-to-GDP (19.1% at March 2025), FRBM central govt debt ceiling (40% of GDP), and debt service ratio (6.6%).

For Mains (GS3): Common formats — analyse India's external debt sustainability; discuss the significance of sovereign green bonds; compare ECB automatic vs approval route; evaluate the FRBM framework's effectiveness. Key arguments: India's low external-debt-to-GDP ratio and overwhelmingly official sovereign debt composition provide insulation; ECB liberalisation (2025 draft) signals confidence; sovereign green bonds integrate fiscal policy with climate finance; Masala bonds help internationalise the rupee while protecting against forex risk.
