Mumbai, Sep 21: The Reserve Bank of India has set the interest rate on the Government of India Floating Rate Bond 2033 at 6.87 per cent per annum for the six month period beginning September 22, 2026.
The new rate will remain applicable until March 21, 2027. It is higher than the 6.75 per cent rate that applied to the bond during the previous half-year period ending September 21.
The RBI announced the revised rate on Monday, ahead of the start of the new interest period. The Floating Rate Bond 2033 carries a coupon that is periodically reset rather than remaining fixed throughout the life of the security.
Under the formula prescribed for the bond, the interest rate is linked to the average Weighted Average Yield of the last three auctions of 182-day Treasury Bills. A fixed spread of 1.22 percentage points is then added to the base rate to determine the coupon applicable for the six-month period.
For the latest reset, September 22 was the rate fixing date. Based on the applicable formula, the resulting coupon has been fixed at 6.87 per cent for the period through March 21 next year.
Floating-rate government securities differ from conventional fixed rate bonds because their coupon is revised periodically according to a predetermined benchmark or formula. This means the interest received by holders can change at each reset date.
The FRB 2033 is issued by the Government of India, with the RBI responsible for announcing the applicable coupon rate. The security forms part of the government securities market and provides investors with an instrument whose interest rate adjusts periodically in line with short-term government borrowing conditions.
The increase from 6.75 per cent to 6.87 per cent represents a 12 basis point rise in the coupon for the latest six-month period.
The change is linked to movements in the yields of 182-day Treasury Bills, since those yields form the basis for calculating the floating coupon. The structure allows the bond’s interest rate to respond periodically to changes in short-term government-security yields.
For retail investors, government securities can be accessed through the RBI Retail Direct platform. Individuals can open a Retail Direct account and participate in eligible primary issuances or buy government securities in the secondary market through the NDS-OM platform.
However, the coupon rate announced by the RBI should not automatically be treated as the effective return an investor will receive when purchasing the security in the secondary market. If a bond is purchased above or below its face value, the investor’s effective yield can differ from the stated 6.87 per cent coupon.
This distinction becomes important when government securities are traded after issuance. The coupon determines the interest payment under the bond’s terms, while the market price influences the actual yield earned by an investor buying the security in the secondary market.
The latest rate announcement comes against a backdrop of continued attention on interest rates, government borrowing costs and movements in the domestic bond market. Short-term Treasury Bill yields play a direct role in determining the coupon for the Floating Rate Bond 2033.
The six-month reset mechanism also means investors receive a rate that can change over time. If the underlying Treasury Bill yields rise, the bond’s coupon could increase at a subsequent reset, subject to the formula. Conversely, a decline in the relevant benchmark yields could result in a lower coupon in a future period.
The 1.22 percentage-point fixed spread provides a predetermined addition to the Treasury Bill-based component. The floating element therefore comes from changes in the average yield of the specified 182-day Treasury Bill auctions.
The latest announcement gives investors a clear reference rate for the coming six months. From September 22, holders of the FRB 2033 will receive interest based on the 6.87 per cent annualised rate applicable to this period.
The bond’s floating structure also distinguishes it from traditional government securities carrying a fixed coupon. While fixed-rate bonds provide the same coupon throughout their tenure, the FRB 2033 is recalculated at six-month intervals.
Government securities are generally considered an important part of India’s fixed-income market and are used by a wide range of investors. The availability of a floating-rate instrument gives market participants another option for managing exposure to changes in interest rates.
The revised rate also illustrates how government borrowing conditions are transmitted into the coupon paid on the security. Because the formula is tied to recent Treasury Bill auction yields, the rate adjusts according to prevailing short-term market conditions rather than remaining unchanged.
For investors considering the bond through the secondary market, the purchase price remains an important factor. As the RBI’s retail investment information notes, buying the security above or below its face value can cause the effective yield to differ from the coupon rate.
The 6.87 per cent rate will therefore serve as the applicable coupon for the next six-month period, while the subsequent rate will be determined according to the prescribed reset mechanism.
The RBI’s announcement provides investors with clarity over the interest payable on the Floating Rate Bond 2033 from September 22, 2026, through March 21, 2027. The increase over the previous 6.75 per cent coupon reflects the latest calculation based on short-term government security yields.
