Indian moms often prefer fixed deposits over mutual fund SIPs. Why? Because FDs guarantee returns. I still remember when I first started earning, my mom insisted I open an account in the post office. That offered nearly 7% interest on FDs then — way higher than what many banks offered after the Reserve Bank of India’s repo rate cut in June 2025.

Back then, even private banks or public-sector banks’ FD rates dropped significantly. Now in September 2025, there’s been a resurgence: some small finance banks are offering up to 8.50% interest, making FDs attractive again for those who want safety plus decent return.

This Bank is Offering Highest Interest Rate on Fixed Deposits

Slice Small Finance Bank has topped the chart in September 2025. It is offering 8.50% per annum on FDs for a tenure of just over 18 months (i.e. 18 months + 1-2 days).

Other small finance banks are also competitive: Jana Small Finance (8.00%), Suryoday Small Finance (8.20%) for longer tenures, Utkarsh Small Finance (≈ 7.65%), ESAF Small Finance offers about 7.60%, etc.

This means that if you lock in money for ~18 months at Slice SFB, you get the highest rate currently in the market among scheduled banks / SFBs.

Why Do Small Finance Banks Offer Higher Interest On FDs than Private Banks?

Small Finance Banks (SFBs) often offer higher rates for fixed deposits compared to large private or public-sector banks. Here are reasons:

Higher Cost of Funds: SFBs typically have more expensive sources of funds; they don’t have as large deposit base, less CASA (Current & Savings Accounts) deposits, so to attract deposits, they must offer higher interest.
Risk & Scale: They are smaller in scale, sometimes newer, with less diversified portfolios. To compensate depositors for risk (perceived or real), interest rates are higher.
Regulatory Constraints: SFBs are regulated by RBI, but because their business model focuses on smaller customers or less wealthy geographies, their margins are tighter. Offering higher FD rates helps them build trust, attract depositors, and maintain liquidity.
Limited Branch Network / Trust: Since many SFBs are regionally focused or less known nationally, offering high FD rates is a way to build brand/trust quickly among depositor communities.

However, this higher return comes with caveats:

Fixed Deposit Insurance via Deposit Insurance and Credit Guarantee Corporation (DICGC) applies, but only up to ₹5 lakh deposit per bank. So if you deposit more than that, the portion above ₹5 lakh may be at risk if the bank faces trouble.
Because of their smaller size or narrower resource base, SFBs may be more sensitive to liquidity stress, economic downturns, etc. Hence, for many conservative investors, safety of large, well-known banks is often preferred.

So while SFBs offer tempting FD rates, they are not always the first choice for risk-averse, large depositors.

Which Private Bank is Offering the Highest Interest Rate on Fixed Deposits?

Here are the latest rates (as of September 2025) for private banks, how they stack up, and who’s leading. First, a few words about why this matters:

Private banks are often viewed as safer than small finance banks (by many depositors), but with lower FD rates. If a private bank starts offering competitive rates, many depositors may shift. The table below compares top private bank FD rates currently.

Table: Private Banks – Top FD Rates in Sept 2025

Here are some private banks and what their highest FD interest rates are, plus the tenure for which they offer these. Source: Paisabazaar & Business Standard.

Private Bank	Highest FD Rate (%) p.a.	Tenure for which this rate is offered
SBM Bank India	7.50%	5 years
Jammu & Kashmir Bank	7.30%	888 days (≈ 2 years + some)
RBL Bank	~7.20%	2-3 years / select tenures
Bandhan Bank	~7.20%	2-3 years or similar tenor
YES Bank	~7.00%	~1.5-5 years (depending on tenure)

What this Suggests

Among private banks, SBM Bank India is currently offering the most competitive long-term FD rate (~5 years) at 7.50%, while others are between ~7.00-7.30%. These rates are significantly lower than what the top small finance banks are offering (~8.50% etc.), yet they do provide more established brand reputation and generally perceived safer balance sheet.

Which Govt. Bank Offers the Highest Interest Rate on Fixed Deposits?

Now turning to public sector banks (PSBs / Govt. banks). These tend to offer lower FDs but are considered very safe for many depositors.

Table: Public & Govt Banks – Top FD Rates in Sept 2025

Below are some of the top rates being offered by public sector banks, and the tenures for those rates. Sources: Business Standard, Paisabazaar.

Public Sector Bank	Highest FD Rate (%) p.a.	Tenure / Scheme
Central Bank of India	~6.75%	very long tenures (2,222 days; 3,333 days)
Indian Overseas Bank	~6.75%	444-day FD scheme
Bank of Maharashtra	~6.70%	~1-2 years / special tenures
Indian Bank / Punjab & Sind Bank	~6.70%	special tenures or ~444 days etc.
State Bank of India (SBI)	~6.60%-6.75%	special term deposits / 1-3 years etc.

Observations & Implications

The public sector banks are offering safely moderate rates, mostly in 6.5%-7% range for longer tenures or special schemes, with few touching ~6.75%. While these are lower than both small finance banks and the better private banks, many depositors accept this trade-off for trust, stability, branch presence, and easier redemption / infrastructure.

Remember This Before Parking Your Money in an FD

Before you lock in your money in a fixed deposit, here are some key points to keep in mind. These aren’t exhaustive but crucial for making a safer, smarter choice.

Here are some considerations:

Deposit Insurance Limit: Deposits in banks (including small finance banks) are insured by DICGC up to ₹5 lakh per depositor, per bank. If you deposit more than that amount, the excess is at risk if something goes wrong. Always check how much of your deposit is “insured.”
Tenure vs Interest Rate: Higher rates often come with specific tenure windows (e.g. 18 months + 1 day, or 5 years). If you withdraw early, you may lose part of interest or incur penalty.
Reinvestment Risk / Renewal Rates: When your FD matures and you reinvest, rates may be lower. Especially if inflation and RBI policy are changing, the next rate might be lower.
Liquidity & Premature Withdrawal Penalties: If you need money before maturity, the penalty could reduce your effective return significantly.
Bank’s Financial Health / Track Record: SFBs are regulated, but not all are equally strong financially. Check the bank’s asset quality, credibility, credit ratings, reviews, and their customer service.
Taxes and TDS: Interest from FDs is taxable. TDS is deducted if the interest income crosses certain thresholds. Senior citizens can use Form 15H / 15G to avoid TDS under some conditions. Make sure you know the post-tax return, not just the nominal rate.
Inflation Risk: If inflation is high, even 8% may not guarantee high “real returns.” So evaluate what you do with the interest — whether monthly payout / cumulative etc.

Conclusion

FD rates have risen again in September 2025, especially among small finance banks, with some offering up to 8.50% for ~18-month tenures. This is a strong contrast to what many public sector banks and large private banks are offering (≈ 6.5-7.5% for similar or longer tenures).

If you are someone who wants guaranteed returns and minimal risk, a well-chosen FD in a credible bank can make sense — especially if you keep within the insured limit. On the other hand, if you are comfortable with some risk or have longer horizons, exploring small finance banks’ offerings might yield higher returns.

In the end, it may come down to balancing return vs safety. Speak with your bank, check the fine print, and perhaps split your investment across banks to diversify risk. That way, you may benefit from better rates while staying secure.
