Small finance bank FDs offer 8.10% vs SBI’s 6.45%: Is the extra 165 bps worth the risk?

Small finance banks are offering fixed deposit rates significantly higher than those available at large banks, with rates going up to 8.10% for select tenures. But before chasing the higher yield, investors need to consider taxation, deposit insurance and the amount that could remain outside the safety net.

According to the Value Research write-up, Suryoday Small Finance Bank offers 8.10% on a 30-month FD, while Jana Small Finance Bank offers 8% and Utkarsh Small Finance Bank offers 8.10% for select tenures. In comparison, large private banks such as HDFC Bank, ICICI Bank and Axis Bank offer around 6.40-6.50%, while SBI offers 6.45% on its 444-day special-tenure FD.

That translates into a rate difference of as much as 165 basis points between Suryoday and SBI. On the surface, the higher rate looks attractive. But the additional return needs to be viewed alongside the protection available to depositors.

That creates a rate gap of as much as 165 basis points between Suryoday and SBI. However, investors need to look beyond the headline rate before deciding whether the additional return adequately compensates for the risks involved.

DICGC cover is limited to ₹5 lakh

Small finance banks are RBI-licensed scheduled banks, and their deposits receive the same DICGC insurance protection as deposits with other scheduled commercial banks. However, the protection is capped at ₹5 lakh per depositor per bank, including principal and accrued interest. It is not ₹5 lakh for each FD held with the bank.

This distinction becomes particularly important for long-term cumulative FDs. A ₹5 lakh deposit earning 8% over five years can grow to around ₹7.35 lakh. While the initial ₹5 lakh falls within the insurance limit, the accumulated interest pushes the maturity amount significantly beyond it.

Tax can narrow the return gap

The headline FD rate is also not the investor's final return. Interest earned on bank FDs is added to taxable income and taxed according to the applicable marginal tax rate. Therefore, investors in higher tax brackets will see a larger portion of the interest income absorbed by tax.

Even after accounting for tax, however, the SFB advantage can remain meaningful compared with a 6.45% SBI FD, depending on the investor's tax slab.

Why do SFBs pay higher FD rates?

The higher rates do not automatically mean that SFBs are unsafe. These banks operate under a different business model from large banks. Their loan books are concentrated more heavily in higher-yielding segments, while they do not have the same low-cost CASA deposit base enjoyed by large banks such as SBI.

As a result, their cost of funds is structurally higher, which can translate into higher deposit rates.

Spread your FD investments

For investors, the choice does not necessarily have to be SFB versus SBI. A more cautious approach is to spread deposits across multiple banks and keep the amount with each bank within the DICGC limit after factoring in expected interest.

FD laddering across different maturities can also provide liquidity and reduce reinvestment risk.

The extra 165 bps can certainly boost FD returns, but it should not be treated as free money. Investors need to weigh the higher yield against the amount that could remain outside the insurance limit and their own tolerance for bank-specific risk.
