RBI Floating Rate Bond Interest Rate 2026: Tax, Returns, Eligibility & Rules

RBI Floating Rate Bonds are one of the few debt investments in India that offer flexibility with returns. Backed by the Government of India and managed by the Reserve Bank of India, these bonds have become a go-to option for investors looking for safety, stable income, and returns that move with the market.

Key Highlights:

• RBI Floating Rate Bonds offer a variable 8.05% interest rate, linked to the NSC rate plus a 0.35% spread.
• They have a 7-year tenure, with early withdrawal allowed for senior citizens.
• Minimum investment is ₹1,000 with no upper limit, and interest is paid semi-annually.
• Interest is fully taxable with TDS, and no capital gains tax applies.

What Are RBI Floating Rate Savings Bonds?

RBI Floating Rate Savings Bonds, 2020 (Taxable), or FRSB 2020 (T), are Government of India securities issued through authorised receiving institutions and made available through the RBI Retail Direct platform as well.

Unlike a conventional fixed-rate deposit, the coupon rate is linked to the prevailing National Savings Certificate (NSC) rate plus a fixed spread of 0.35 percentage points. The rate is reset every six months.

The bonds are designed primarily for investors seeking government-backed fixed-income exposure and periodic interest income rather than capital appreciation.

How Do RBI Floating Rate Savings Bonds Work?

The basic formula is:

FRSB Interest Rate = NSC Interest Rate + 0.35%

For the July–December 2026 period:

NSC rate = 7.70%

FRSB spread = 0.35%

Therefore:

7.70% + 0.35% = 8.05% per annum

The 8.05% rate applies from 1 July 2026 to 31 December 2026. The rate for the following six-month period can change if the applicable NSC rate changes.

This is important: 8.05% is not locked in for the entire seven-year tenure. Only the applicable coupon for each reset period is known in advance.

Current Interest Rate on RBI Floating Rate Savings Bonds 2026

As of August 2026, the current interest rate is:

The RBI has retained the coupon at 8.05% for July–December 2026 because the NSC rate remained at 7.70%.

Key Features of RBI Floating Rate Savings Bonds

The major features include:

• Government-backed security
• 7-year maturity
• 8.05% current annual coupon for July–December 2026
• Interest paid twice a year
• Coupon reset every six months
• Minimum investment of ₹1,000
• Additional investment in multiples of ₹1,000
• No maximum investment limit
• Non-tradable and generally non-transferable
• No cumulative interest option
• Interest is taxable
• Premature redemption is available only to eligible senior citizens under specified conditions

The bonds are held electronically in a Bond Ledger Account rather than being traded like listed corporate bonds.

Who Can Invest in RBI Floating Rate Savings Bonds?

Eligible investors generally include:

• Resident Indian individuals
• Individuals investing jointly
• Individuals investing on behalf of a minor
• Hindu Undivided Families (HUFs)

Non-Resident Indians (NRIs) are not eligible to subscribe to these bonds.

Investors should verify their eligibility and the currently authorised receiving offices before making an application.

Minimum and Maximum Investment Limits

The minimum investment is ₹1,000, and subsequent investments must generally be made in multiples of ₹1,000.

There is no prescribed maximum investment limit for the bonds.

For example:

• ₹1,000 investment → eligible
• ₹50,000 investment → eligible
• ₹5 lakh investment → eligible
• ₹25 lakh investment → eligible
• ₹1 crore investment → no scheme-level maximum limit

However, the absence of a maximum limit does not mean an investor should allocate all surplus funds to one instrument. Liquidity, taxation, asset allocation and future cash-flow requirements still matter.

Interest Payment & Calculation

Interest is calculated on the nominal investment amount and paid semi-annually. There is no cumulative option, meaning the interest is paid out rather than automatically reinvested into the bond.

Example: ₹25 lakh investment

₹25,00,000 × 8.05% = ₹2,01,250 annual interest

Semi-annual payment:

₹2,01,250 ÷ 2 = ₹1,00,625

These figures are before tax.

For comparing investment returns, you can also use an online investment and tax calculator to evaluate different principal amounts and tax assumptions.

Lock-in Period and Premature Withdrawal Rules

The standard maturity period is seven years from the date of issue. RBI's operational guidelines provide a special premature encashment facility for eligible senior citizens.

The applicable lock-in periods are:

For eligible premature redemption, a penalty equivalent to 50% of the last six months' interest is applicable under the scheme rules. Redemption is made on the next applicable interest payment date.

Therefore, these bonds should not be treated as an emergency fund or highly liquid investment.

Taxation of RBI Floating Rate Savings Bonds

The most important tax consideration is that interest from FRSB 2020 (Taxable) is taxable at the investor's applicable income-tax slab rate.

The interest is not tax-free merely because the security is issued by the Government.

Is the investment eligible for Section 80C deduction?

No.

Investment in RBI Floating Rate Savings Bonds does not qualify for a deduction under Section 80C merely because it is a government-backed security.

Section 80C has an aggregate limit of ₹1.50 lakh for eligible investments and payments, but FRSB investment itself is not an eligible 80C deduction.

The distinction is important because instruments such as eligible NSC investments can fall within Section 80C, whereas FRSB investment does not receive the same treatment.

Is Section 80TTA applicable?

Section 80TTA provides a deduction of up to ₹10,000 for eligible savings-bank-account interest for non-senior citizens. It does not convert FRSB interest into tax-free income.

What about Section 80TTB?

Section 80TTB provides eligible resident senior citizens a deduction on specified interest from deposits with banks, post offices and cooperative banks, subject to its conditions. FRSB interest should not automatically be treated as qualifying deposit interest for this deduction.

TDS on FRSB interest

From 1 October 2024, the tax rules provide a ₹10,000 annual threshold for TDS on interest from Floating Rate Savings Bonds. Where the applicable threshold is exceeded, TDS can apply under Section 193.

TDS is only tax deducted at source; it is not necessarily the investor's final tax liability. The final liability depends on the investor's total taxable income and applicable tax provisions.

Benefits of RBI Floating Rate Savings Bonds

1. Sovereign backing

The bonds are issued by the Government of India, providing a high level of credit security compared with unsecured corporate debt.

2. Attractive current coupon

At 8.05%, the current coupon provides a relatively high nominal income for a sovereign-backed instrument.

3. Semi-annual cash flow

Investors receive interest twice a year, which can be useful for planned income requirements.

4. No investment ceiling

There is no scheme-level maximum investment limit, allowing investors to allocate larger amounts where appropriate.

5. Floating-rate structure

Because the coupon is linked to the NSC rate, future coupon rates can move upward or downward with changes in the benchmark.

What Can Cause the RBI Floating Rate Bond Interest Rate to Change?

The interest rates on RBI Floating Rate Bonds are dynamic and are revised every six months based on specific economic indicators. Understanding these influencing factors can help investors anticipate potential rate changes and make informed decisions.

Inflation

• Inflation influences how the RBI sets interest rates. 
• When inflation is high, the RBI often raises the repo rate to reduce spending and control prices. 
• This can lead to better returns for bondholders. During low inflation, the RBI may cut rates, which could lower the returns on floating rate bonds.

Economic Conditions

• Economic growth, employment, and overall financial health also affect interest rates. 
• If the economy is strong, the RBI may increase rates to prevent overheating, which usually benefits bondholders. 
• In weaker economic phases, the RBI may lower rates to boost growth, which might reduce bond payouts.

Risks and Limitations

Despite the government backing, the bonds have important limitations.

Interest-rate risk

The current 8.05% rate is not guaranteed for seven years. If the NSC rate falls, the FRSB coupon can fall at the next reset.

Liquidity risk

The bonds are not freely tradable in the secondary market. Investors below 60 generally cannot access the senior-citizen premature redemption facility.

Tax risk

An 8.05% gross return can become considerably lower after income tax.

For example, ignoring surcharge and assuming a 4% cess:

Actual tax may differ depending on the taxpayer's total income, regime, surcharge and other applicable provisions.

Inflation risk

The nominal interest rate does not guarantee a real return. If inflation rises substantially, purchasing power can still decline.

How to Invest in RBI Floating Rate Savings Bonds

1. Check eligibility
2. Complete KYC
3. Select FRSB
4. Enter investment amount
5. Provide bank and nominee details
6. Make payment
7. Receive confirmation/holding documentation

Investors should use the current RBI Retail Direct platform or an authorised receiving institution rather than relying on unofficial investment channels.

Documents Required

• Visit a designated bank branch (like SBI, HDFC, ICICI) or post office, or log in to your bank’s internet banking.
• RBI bonds can also be bought through brokers

• Date-of-birth proof for eligible senior citizens seeking premature redemption.

Nomination is available under the scheme, subject to applicable rules.

Who Should Consider Investing?

RBI Floating Rate Savings Bonds may be suitable for investors who:

• Prioritise capital preservation
• Want sovereign-backed fixed-income exposure
• Can remain invested for several years
• Want semi-annual income
• Do not require immediate liquidity
• Understand that the coupon can change
• Are comfortable paying tax on interest income

They can be considered as one component of a broader fixed-income allocation rather than as a complete investment portfolio.

Who Should Avoid These Bonds?

They may be unsuitable for investors who:

• Need access to the money within a few years
• Need monthly rather than half-yearly income
• Want a guaranteed rate for the entire seven-year period
• Are primarily looking for tax-saving investments
• Want an instrument that can be sold easily in the secondary market
• Have not established an adequate emergency fund

Investors should also avoid concentrating their entire fixed-income allocation in a single product simply because its current coupon looks attractive.

Real-World Example of RBI Floating Rate Savings Bonds

Consider an investor who invests ₹10 lakh at the current 8.05% coupon.

Gross income

Annual interest:

₹10,00,000 × 8.05% = ₹80,500

Half-yearly interest:

₹40,250

Now assume the investor's marginal tax rate is 30% plus 4% cess, ignoring surcharge.

Approximate tax:

₹80,500 × 31.2% = ₹25,116

Approximate post-tax interest:

₹80,500 − ₹25,116 = ₹55,384

Effective post-tax yield:

₹55,384 ÷ ₹10,00,000 = 5.54%

This demonstrates why investors should compare post-tax returns, not simply headline interest rates.

If the coupon changes in a subsequent six-month period, future interest payments will also change.
