About First Blue Bond
- Definition: Blue bonds are debt instruments that fund sustainable water and marine projects: clean water, recycling, shipping, sustainable fishing, ocean energy and mapping.
- Issuer: Sagarmala Finance Corporation Ltd (SMFCL), a central public sector enterprise and India’s first maritime-focused lender.
- Date: Maiden blue bond issue on 28 September 2026.
- Size: Up to ₹600 crore (₹6 billion, about $62.6 million), which includes a greenshoe option of ₹500 crore. The base is ₹100 Crore.
- A greenshoe option lets an issuer raise extra money beyond the base issue if investor demand is strong. In Sagarmala’s blue bond, up to ₹500 crore more can be retained. The name comes from the Green Shoe Manufacturing Company, the first to use it (1963).
- Tenor: 10-year bonds, as per a provisional term sheet.
- Use of money: Maritime sector lending, greenfield port projects and coastal road networks, to be used within FY 2026-27.
- Rating and arranger: AA+ by ICRA and CARE; SBI Capital Markets is the arranger. Large insurers and provident funds are the target investors.
- Global first: Seychelles issued the world’s first sovereign blue bond in 2018, with World Bank support, to fund sustainable fisheries.
- SEBI (Issue and Listing of Non-Convertible Securities) Regulations, 2021: Define ‘green debt securities’. In 2023, SEBI widened the definition to include blue bonds (water and maritime), yellow bonds (solar) and transition bonds.
Why this matters for India?
- India has a long coastline (officially re-measured at about 11,098 km in 2025, up from 7,517 km), an EEZ of over 2 million sq km, and 12 major ports.
- About 95% of India’s trade by volume moves by sea, so port finance is central to trade competitiveness.
- Government plans such as the Sagarmala Programme (2015), Maritime India Vision 2030, Maritime Amrit Kaal Vision 2047 and the Deep Ocean Mission (2021) need long-term, low-cost money.
- A blue bond opens a new pool of investors (ESG funds, insurers, pension funds) for maritime projects.
Concerns that remain
- Is it really ‘blue’? The money will fund greenfield ports and coastal roads. These can damage mangroves, coral reefs and fishing grounds, and may clash with Coastal Regulation Zone (CRZ) rules. Without strict impact reporting, this risks ‘blue-washing’.
- Small size, big need: ₹600 crore is tiny next to the lakhs of crores planned under Sagarmala. The real value is in creating a market and a benchmark, not in the amount.
- No national taxonomy yet: India is still finalising its climate finance taxonomy (a draft was released in 2025). Without it, what counts as ‘blue’ is judged against global guides like ICMA principles.
- Sustainable fisheries and coastal communities are left out of the stated use of proceeds, though they are central to the blue economy.
Types of bonds in India: a comparison
| Type of bond | What the money funds | Framework in India | Example / status |
| Green bond | Environmental projects: renewable energy, clean transport, energy efficiency, waste management, pollution control, climate adaptation | SEBI green debt securities rules (2017; revised 2023, now in NCS Regulations 2021) | Sovereign green bonds since 2023; many PSU and corporate issues (e.g. IREDA, NTPC) |
| Blue bond | Water and ocean economy: clean water, wastewater, sustainable fishing, shipping, ports, marine conservation, ocean energy | A sub-category of green debt securities under SEBI (added 2023) | Sagarmala Finance, 28 Sept 2026 (first in India); Vadodara municipal blue bond planned. World’s first sovereign blue bond: Seychelles (2018) |
| Yellow bond | Solar energy generation and related infrastructure | A sub-category of green debt securities under SEBI (added 2023) | Recognised label; issuances so far are rare |
| Transition bond | Helping polluting firms shift to cleaner operations (e.g. steel, cement, power moving to lower emissions) | A sub-category of green debt securities under SEBI (added 2023) | Key for ‘hard-to-abate’ sectors; risk of greenwashing |
| Social bond | Social outcomes: affordable housing, health, education, basic infrastructure, food security, jobs | SEBI ESG debt securities framework (5 June 2025) | Must follow ICMA or similar global principles |
| Sustainability bond | A mix of green and social projects | SEBI ESG framework (2025); must meet both green and social rules | Use of proceeds split across both types of projects |
| Sustainability-linked bond (SLB) | General purposes. The money is not tied to projects; instead the interest rate is tied to the issuer meeting sustainability targets (KPIs) | SEBI ESG framework (2025) | If the target is missed, the coupon usually steps up (issuer pays more) |
| Sovereign green bond (SGrB) | Government spending on green public projects (solar, green hydrogen, metro rail, afforestation) | Sovereign Green Bonds Framework (Nov 2022), issued by RBI for the Centre | First issue Jan–Feb 2023, ₹16,000 crore in two tranches; reviewed by CICERO |
Remember the key split: green, blue, yellow, transition, social and sustainability bonds are use-of-proceeds bonds (the money is tied to projects). A sustainability-linked bond is outcome-based (the money is free to use, but the interest rate depends on meeting targets).
Way forward: a national taxonomy; mandatory impact reporting; credit enhancement for smaller issuers; linking blue bonds to CRZ compliance and fishing community welfare to fulfill SDG 6 and 14.
Practice MCQ
Q1. With reference to sustainable finance in India, consider the following statements:
- Under SEBI’s rules, blue bonds and yellow bonds are sub-categories of green debt securities.
- Yellow bonds are issued to finance sustainable fisheries and marine conservation.
- Sagarmala Finance Corporation is registered with the RBI as a Non-Banking Financial Company.
Which of the statements given above are correct?
(a) 1 and 2 only (b) 1 and 3 only (c) 2 and 3 only (d) 1, 2 and 3
Answer: (b). Statement 2 is wrong: yellow bonds finance solar energy. Sustainable fisheries fall under blue bonds.
Q2. Consider the following statements:
Statement I: In a sustainability-linked bond, the issuer is not required to spend the money raised on specific green projects.
Statement II: In a sustainability-linked bond, the interest rate is linked to whether the issuer meets pre-set sustainability targets.
Which one of the following is correct?
(a) Both statements are correct and Statement II explains Statement I
(b) Both statements are correct but Statement II does not explain Statement I
(c) Statement I is correct but Statement II is incorrect
(d) Statement I is incorrect but Statement II is correct
Answer: (a). An SLB is outcome-based, not use-of-proceeds based. Because the reward or penalty works through the coupon, the money itself need not be tied to projects.
