Overview
In December 2017, Indian Rail Finance Corporation (IRFC), the dedicated market borrowing arm of Indian Railways, issued its first USD-denominated green bond in the international debt market. This move marked a significant step forward in India’s commitment to financing sustainable infrastructure through credible ESG instruments.
Purpose & Impact
The proceeds from the green bond were earmarked for projects that align with the Climate Bonds Initiative (CBI) standards and SEBI’s emerging ESG framework, including:
Railway Electrification
Electrification of railway lines helps reduce dependence on diesel-powered locomotives.
Supports India’s goal to have net-zero carbon emissions from railways by 2030.
Energy-Efficient Infrastructure
Investment in energy-efficient rolling stock (e.g., electric locomotives and modern wagons).
Electrified routes reduce carbon emissions by nearly 50% compared to diesel-powered trains.
Dedicated Freight Corridors
Development of green freight corridors enhances logistics efficiency.
Reduces road congestion, fuel consumption, and carbon footprint of bulk cargo transport.
Investor Reception
The bond was oversubscribed 3 times, receiving strong interest from:
Global institutional investors
Sovereign wealth funds
ESG-aligned investment portfolios
High subscription levels indicated strong investor confidence in:
India’s sustainable transport roadmap
Credibility of IRFC as a public sector borrower
Transparency of green bond reporting
Regulatory & ESG Alignment
Certified under the Climate Bonds Standard (CBI certification).
Complies with the Green Bond Principles (GBP) of the International Capital Market Association (ICMA).
Aligned with SEBI’s disclosure norms on use-of-proceeds, impact tracking, and third-party validation (later formalized more strongly in India from 2021 onwards).
Strategic Significance for Bharat
First green bond by an Indian railway entity on an international platform.
Showcased India’s commitment to sustainable development and clean mobility.
Helped build a precedent for more sovereign and semi-sovereign issuances in the ESG space.
Contributed to India’s broader climate goals under the Paris Agreement and SDG 9 (Industry, Innovation, and Infrastructure).
Current status of IRFC’s USD 500 million Green Bond, issued in December 2017 with a 10-year tenor:
Maturity Date
The bond matures on 13 December 2027, exactly 10 years after issuance (irfc.co.in).
Interest and Redemption
Investors receive interest at a fixed 3.835% per annum, paid semi-annually (irfc.co.in).
No redemption or principal repayment has occurred yet—the bond was structured to return the full principal at maturity alongside the final interest installment.
What Happens Next
As the bond approaches maturity, IRFC has until December 2027 to fulfill the redemption obligation.
Upon maturity, investors can expect:
The final semi-annual interest payment
Full return of principal in USD
Recent Developments at IRFC
In May 2025, IRFC received approval to issue up to ₹100 billion in deep-discount (zero-coupon) bonds, also with 10-year maturity and redemption by March 2027 (reuters.com).
These zero coupon bonds won’t pay periodic interest; instead, investors receive their returns through discounted redemption.
This is separate from the 2017 green bond but indicative of IRFC’s continued presence in debt markets.
Looking Ahead
Between now and December 2027, monitor corporate filings and IRFC disclosures for updates on redemption logistics and timing.
This green bond stands as IRFC’s first USD green issuance and remains a benchmark for public sector sustainable finance in India.
Proceeds Deployment & Purpose Fulfillment
Earmarked Green Projects
From the outset, the bond proceeds were committed to "Eligible Green Projects", certified by the Climate Bonds Initiative, including:
Dedicated Freight Railway Lines: electrification, infrastructure upgrades, and rolling stock (locomotives, wagons)
Public Passenger Transport Services: electrified tracks, modern passenger trains, and associated infrastructure (irfc.co.in, scribd.com)
Management & Tracking of Funds
Segregated & Audited
IRFC maintains separate accounts for green bond proceeds to ensure transparency.
A retainer firm of Chartered Accountants administers these funds, supported by internal audits and regular financial reviews (scribd.com).
Annual Reporting
Each year, IRFC publishes updates showing how much of the bond proceeds have been allocated to specific projects.
Post-issuance certification by an independent reviewer ensures ongoing compliance with green bond standards, under oversight from Climate Bonds Initiative (scribd.com).
Actual Impact & Progress
IRFC data confirms that the proceeds have been actively used for powering India’s railway electrification and rolling stock upgrades—reflecting real, measurable progress toward decarbonizing freight and passenger rail transport (in.marketscreener.com).
The initiative aligns with national goals to increase electrified railway corridor share from ~36% at issuance to 45% by 2030 (as of 2021 reporting) (in.marketscreener.com).
Summary Snapshot
Takeaway for Bharat
IRFC’s green bond is a textbook example of responsible ESG financing: the funds have been tracked, audited, and deployed into sustainable rail infrastructure. With maturity approaching in December 2027, investors can be confident that the bond achieved its intended environmental impact—supporting a cleaner, electrified railway ecosystem in India.
How Will IRFC Repay the Principal and Interest of the USD 500 Million Green Bond (Due Dec 2027)?
First, understand IRFC’s business model:
The Indian Rail Finance Corporation (IRFC) is a Government of India-owned non-banking finance company (NBFC). It acts as the financing arm of the Indian Railways, and its role is not to run railways but to raise funds (like bonds or loans) and lend them to the Ministry of Railways (MoR).
Step-by-Step Flow of Funds:
1. IRFC raises capital from domestic and international investors through:
Green bonds (like the USD 500M in 2017)
Tax-free bonds
Term loans, ECBs (external commercial borrowings)
2. IRFC lends this money to Indian Railways, with:
A lease-based repayment model
The lease covers interest + principal amortization + margin over a fixed period (usually 30 years)
3. Indian Railways repays IRFC every year from its Revenue Budget, through:
Freight and passenger earnings
Budgetary support from the Ministry of Finance (Govt. of India)
Internal accruals and monetization projects
4. IRFC uses this lease rental to:
Pay interest to bondholders every 6 months
Repay the principal on maturity
Interest Payments: Already Happening
IRFC has been paying interest semi-annually since 2017.
Source: The lease rentals from Railways include a dedicated component for interest servicing.
This has not been defaulted—credit ratings remain strong (often AAA domestically).
Principal Repayment (Due in Dec 2027): Fully Planned
The entire principal amount of USD 500M is due in one bullet payment on maturity.
The funding for this will come from:
Long-term lease payments from the Ministry of Railways
Rolling over bonds or issuing fresh debt (if required)
GoI support, if needed (but not usually required due to self-sufficiency of the model)
But the Projects Were Capital-Intensive—No Direct Income?
True, railway electrification or freight corridors don’t always generate immediate income. However:
IRFC’s structure is not project-revenue-dependent like a private infrastructure bond.
Instead, it’s backed by the creditworthiness of the Government of India and guaranteed lease payments from the Ministry of Railways.
So even if a project is non-revenue-generating (like electrification), IRFC still receives payment from the Railways.
Risk Protection
Sovereign Shield: Since IRFC’s only client is the Ministry of Railways, and it is a GoI-owned entity, the bond has quasi-sovereign backing.
No direct link to project revenue: That’s why IRFC has AAA ratings, and foreign investors trust its paper.
IRFC's repayment model is low-risk and government-backed, even if the funded projects are capital-intensive and not instantly profitable. The structured lease rental system ensures steady cash flow, enabling timely interest servicing and principal repayment in 2027—without relying on project revenues alone.
Why IRFC Issued Its Green Bonds Outside of Bharat
1. Access to Global Capital at Lower Interest Rates
International markets often offer lower coupon rates than domestic ones for high-rated issuers.
For example, IRFC’s 2017 green bond was issued at 3.835% USD, while similar domestic rupee bonds might have cost 6.5–8% INR.
This difference is due to:
High demand for ESG instruments globally
Strong appetite for sovereign-backed emerging market debt
Dollar-denominated instruments carry lower inflation risk for global investors
2. Attracting ESG-Focused Foreign Investors
The global ESG market is massive, with institutional investors (like pension funds, sovereign wealth funds, and climate-aligned funds) mandated to invest in green-certified instruments.
By issuing on the London Stock Exchange (LSE), IRFC could tap:
Dedicated ESG bond funds
Climate-focused banks and asset managers (e.g., BlackRock, Allianz, etc.)
Better pricing and higher oversubscription
3. Reputation & International Benchmarking
Issuing a green bond on an international platform:
Raises the issuer's credibility
Establishes an international benchmark for Indian green bonds
Sets a precedent for other Indian PSUs (public sector undertakings)
4. Foreign Currency Requirement
Indian Railways often purchases imports (locomotives, electrical systems, signaling) in foreign currency (mainly USD or EUR).
USD-denominated bonds match those needs better than rupee bonds — avoiding currency conversion risk.
Why Not on Bharat Exchanges?
Bharat Has Progressed Since Then
Post-2021, SEBI has formalized ESG frameworks, including:
Business Responsibility and Sustainability Reporting (BRSR)
Green bond disclosures and taxonomy
The ESG investor base within Bharat is also rapidly growing.
Key Takeaway
IRFC’s green bond is a landmark example of public sector-led ESG finance in Bharat. It not only enabled environmentally aligned infrastructure development but also boosted India’s credibility in the global green bond market. As the nation scales up its clean transportation and logistics goals, such green issuances represent the future of infrastructure financing in India—clean, transparent, and aligned with global sustainability standards.
Conclusion
IRFC issued its green bond abroad in 2017 to:
Tap into cheaper, ESG-focused global capital
Match funding currency with procurement needs
Build India’s presence in international sustainable finance
At the time, Bharat’s domestic green bond ecosystem was limited—but today, things are changing fast.
