What Exactly Are Sovereign Green Bonds?
Think of a regular government bond: you lend money to the government, and in return, you receive periodic interest payments and your principal back at maturity. Sovereign Green Bonds (SGrBs) work just like that, with one crucial difference: the money you invest
is specifically earmarked for projects with positive environmental benefits. First announced in the 2022-23 Union Budget, these bonds are issued by the Reserve Bank of India (RBI) on behalf of the Government of India. The 'sovereign' tag means they are backed by the full faith and credit of the government, making them one of the safest investment instruments available. The 'green' label ensures your funds are channelled exclusively into building a sustainable future for the country.
Fuelling India's Green Infrastructure
The proceeds from SGrBs are not used for general government expenditure. Instead, they are funnelled into a portfolio of eligible green projects defined by a strict framework. These initiatives are central to India’s goal of achieving net-zero emissions by 2070. A significant portion of the funds raised so far have been allocated to the Indian Railways for acquiring energy-efficient electric locomotives. Other key areas include financing metro rail projects in various cities, developing renewable energy sources like solar and wind power, sustainable water and waste management, and climate change adaptation projects. Projects involving fossil fuels are explicitly excluded.
The Investor's Angle: Returns and Security
For investors, SGrBs offer the dual benefit of a predictable, fixed income and the security of a government guarantee. Like other government securities, they pay interest, known as a coupon, twice a year. At the end of the bond's tenure, which can range from five to thirty years, the principal amount is returned to the investor. The yields on these bonds are comparable to traditional government securities. For instance, past issuances have seen yields in the range of 7.1% to 7.3%. While there is no special tax exemption on the interest earned—it is taxed at your applicable slab rate—the combination of safety, impact, and steady returns makes them a compelling choice for diversifying a portfolio.
Risks and Important Considerations
No investment is without risk. While SGrBs have near-zero credit or default risk thanks to the sovereign guarantee, they are subject to interest rate risk. If interest rates in the economy rise after you buy a bond, its market price could fall if you need to sell it before maturity. Liquidity can also be a concern; while the bonds are listed on exchanges, the secondary market may not always be as active as for conventional government bonds, which could make selling them quickly a challenge. Another risk often discussed in the context of green finance is 'greenwashing', where the environmental impact of projects is overstated. However, the government's framework, with its defined project categories and reporting requirements, aims to ensure transparency and accountability.
How to Invest in India's Green Future
Investing in SGrBs has become increasingly accessible for retail investors. The most direct method is through the RBI's Retail Direct Gilt (RDG) Account, which allows individuals to buy government securities directly in primary auctions without a broker. Alternatively, investors can use their existing demat accounts with brokerage platforms like Zerodha's Kite or others, which facilitate bidding for these bonds when they are auctioned. These bonds are also traded on the secondary market, meaning you can buy and sell them like stocks through a broker, though holding them to maturity is often the ideal strategy for fixed-income investors.
