RBI Announces 6.52% Interest on FRB 2031 for December 2025–June 2026

The Reserve Bank of India (RBI) has declared the interest rate for the Floating Rate Bond 2031 (FRB 2031) for the half-year period from 7 December 2025 to 6 June 2026. The rate will be 6.52% per annum and will apply to all existing FRB 2031 holdings during this period.

What is FRB 2031?

Floating Rate Bonds (FRBs) are government debt instruments with interest rates that change periodically, unlike regular fixed-rate bonds. The coupon on FRB 2031 is adjusted every six months based on a transparent RBI formula.

The interest rate is designed to protect investors from rising market rates, as the coupon increases when benchmark yields rise. This makes FRBs a suitable investment for those looking for stable returns in a changing interest rate environment.

How is the Interest Rate Calculated?

The FRB 2031 interest rate is set using a clear RBI framework:

1. Take the weighted average yield of the last three 182-day Treasury Bill (T-bill) auctions before the rate-setting date.
2. Add a fixed spread of 1% to this average yield.

For the current half-year period, this formula results in an interest rate of 6.52% per annum.

The next rate revision for FRB 2031 is scheduled for 7 June 2026, using the same methodology.

Floating Rate Bonds vs Fixed-Rate Bonds

FRBs differ from traditional bonds in key ways:

• They adjust with market rates, offering protection against rising interest rates.
• Their calculation is transparent, based on RBI’s framework.
• They provide investors with competitive returns, even when market rates fluctuate.

This makes FRBs a preferred choice for risk-conscious investors seeking predictable income without being locked into a fixed coupon rate.

Conclusion

The RBI’s declaration of a 6.52% interest rate for FRB 2031 highlights the benefits of floating rate bonds for investors. By linking returns to market benchmarks, FRBs protect against rising interest rates while offering transparent and reliable income. Investors can consider FRB 2031 as a government-backed instrument that balances security and potential for competitive returns in the changing interest rate environment.
