RBI Floating Rate Savings Bonds are considered low-risk investments that offer market-linked returns, with interest rates resetting every six months. As of January 2026, these RBI floating rate savings bonds offer an interest rate of 8.05% per annum, which is significantly higher than fixed deposit returns.
RBI floating rate savings bonds are low-risk, government-backed debt instruments with a 7-year lock-in period.
The interest rate on RBI floating rate savings bonds resets every six months as per the return on National Savings Certificate (NSC) rate, plus a fixed spread of 0.35%.
RBI floating rate bonds are suitable for risk-averse investors seeking guaranteed and regular income.
Since the interest rate on RBI floating rate bonds resets every six months, it adjusts your returns with interest rate movements, potentially offsetting the impact of inflation.
Earlier, risk-averse investors primarily had two investment options: Real estate and Fixed Deposits (FDs). Due to these limited choices, the older generation, often wary of the volatile stock market, preferred investing in real estate, FDs, or small savings schemes.
To offer a market-linked and low-risk investment, RBI introduced Floating Rate Savings Bonds (FRSB). Let’s understand what RBI floating rate bonds are, how they work, and whether they are the right investment for you.
RBI floating rate bonds are government-backed debt instruments with a 7-year lock-in period that offer market-linked returns. The interest rate on these bonds is determined every six months, i.e., on 1st January and 1st July, and is linked to the National Savings Certificate (NSC) rate.
Here’s how the interest rate on RBI floating rate saving bonds is calculated.
Interest on RBI Floating Rate Savings Bonds = Interest rates on NSCs + a fixed spread rate of 0.35%.
For example, currently the interest rate on NSC is 7.70%.
Interest on RBI Floating Rate Saving Bonds = 7.70% + a fixed spread rate of 0.35% = 8.05%
When you invest in RBI floating rate savings bonds, your capital is locked in for seven years and earns semi-annual interest, providing a steady additional income.
RBI floating rate savings bonds require a minimum investment of ₹1,000, and only resident individuals and Hindu Undivided Families (HUFs) are eligible to invest in them.
RBI floating rate bonds are low-risk investments and offer guaranteed returns, making them suitable for the following investors.
Senior citizens or retired individuals seeking safe investments to earn additional semi-annual income can invest in RBI floating rate bonds, as they offer interest payments every 6 months.
Investors with a low-risk appetite who prioritise capital protection and low risk of default over high returns can invest in these government-backed bonds.
RBI floating rate savings bonds are a suitable choice for investors seeking capital preservation for long-term goals, such as retirement and a child's education.
Inflation is a growing concern for investors as it erodes the value of return on investment. It is essential to invest in securities that keep pace with the growing inflation to ensure your returns are inflation-protected.
Other than offering inflation-adjusted returns, the following are the advantages of investing in RBI floating rate bonds in India.
RBI floating rate savings bonds are issued by the RBI on behalf of the government of India and hence offer maximum safety.
Floating rate bonds offer bi-annual interest payments that act as an additional source of income for the investors.
Returns on Fixed Deposits (FDs) are often significantly less than the interest rate on RBI floating rate bonds, which is adjusted bi-annually for as per interest rate changes.
Unlike FDs, the interest rate of floating-rate savings bonds is reset every six months to adjust to benchmark interest rates.
Both FDs and RBI floating rate savings bonds are long-term investments suitable for risk-averse investors. Let’s compare the two investments so you can make an informed investment decision.

RBI floating rate savings bonds have a strict seven-year lock-in period and cannot be traded or transferred in the secondary market, making them highly illiquid.
Investors under 60 years of age are not allowed to prematurely withdraw their capital. While senior citizens are permitted to make premature withdrawal, they are subject to a strict 4-6 year lock-in period and a penalty equal to 50% of their last coupon payment.
