What Are Sovereign Green Bonds?
Think of a Sovereign Green Bond (SGB) as a loan you give to the government for a specific, eco-friendly purpose. Unlike regular government bonds where the money can be used for any public expense, the funds raised from SGBs are exclusively earmarked for projects
that benefit the environment. The Reserve Bank of India (RBI), on behalf of the Government of India, issues these bonds to raise capital for initiatives like solar and wind farms, clean transportation systems such as metro rails, and waste management projects. This ensures your investment directly contributes to India's national sustainability goals, including its target of achieving net-zero emissions by 2070.
How Do They Generate Returns?
From an investor's perspective, SGBs function very similarly to traditional government bonds. They are fixed-income instruments, which means they pay a predetermined interest rate, known as the coupon rate, to the investor. These interest payments are typically made semi-annually throughout the bond's tenure. At the end of the bond's term, or maturity date, the government repays the initial principal amount to the investor. Because they are issued by the central government, they come with a sovereign guarantee, making them one of the safest investment options available with minimal credit risk.
The 'Greenium': A Price for Impact
A fascinating aspect of green bonds is a phenomenon known as "greenium." This refers to the slightly lower interest rate that green bonds sometimes offer compared to their non-green government counterparts. This small difference reflects the high demand from investors who are willing to accept a marginally lower yield in exchange for the assurance that their money is funding sustainable activities. Essentially, investors pay a small premium for the environmental impact, which in turn helps reduce the government's borrowing costs for crucial green infrastructure projects.
Understanding the Risks and Tax Rules
While SGBs are very safe in terms of credit risk, they are not entirely risk-free. Like all bonds, their market price can fluctuate with changes in overall interest rates. If you decide to sell your bond before it matures, its price could be lower than what you paid if interest rates have risen. Another consideration is taxation. The interest income you earn from SGBs is fully taxable and is added to your total income, to be taxed at your applicable slab rate. There are generally no special tax exemptions for investing in them, though certain specific bonds may offer benefits under rules like Section 54EC for capital gains from property sales.
How to Invest in SGBs
Investing in SGBs has become increasingly accessible for retail investors. You can participate in primary auctions directly through the RBI's Retail Direct portal, which allows you to buy government securities without a broker. Alternatively, you can invest through brokerage platforms like Zerodha's Kite or other SEBI-registered online bond platform providers when new issues are announced. After they are issued, SGBs are also listed and traded on the stock exchanges, allowing you to buy or sell them in the secondary market through a standard demat and trading account, just like stocks.
