The RBI raised the repo rate by 25 basis points to 5.50% from 5.25% on 7 October 2026, and savers are now looking at their deposits and mutual fund holdings to see how the comparison of FD vs debt fund vs arbitrage fund has changed. The decision was effective immediately, and many families are checking what it means for the money they have kept in each of these three places.
This is the first rise in the repo rate since February 2023, when the rate had been set at 6.50%. The last move before this one was a cut of 25 basis points in December 2025 which brought the rate down to 5.25%. People who had adjusted to lower returns on deposits in the last few months are now getting the news in the opposite direction.
The RBI has also changed its policy stance from neutral to "calibrated tightening". In plain words, the central bank is signalling that it is prepared to keep policy tight if required, and it is no longer waiting in a neutral position. One report says the vote on the rate decision was unanimous at 6-0, while the vote on the stance was split 4-2, so some members of the committee had a different view on the wording.
Other policy rates have moved with the repo rate too. The standing deposit facility, or SDF, at which banks park their surplus money with RBI has risen to 5.25%, up from 5.00% earlier. The marginal standing facility, MSF and the Bank Rate are both at 5.75%, whereas MSF was 5.50% before this decision.
Rate cuts now look unlikely in the near term. With the stance moving towards tightening, banks and fund managers will be reading the decision as a sign that borrowing and deposit costs may stay firm or move higher, and FD rates and debt fund yields are expected to reprice upward over time.
But a higher policy rate does not touch every product the same way or at the same speed. A bank FD changes only when a new deposit is made or an old one is renewed, a debt fund shifts its value by the yields of the bonds it holds and an arbitrage fund depends on a completely different set of factors. The tax paid on the return is also different for each of them, so the final amount that reaches the investor can be quite a lot different from the headline number.
Why the inflation and growth forecasts matter to savers
In addition to the repo rate change, the RBI also updated its forecasts for prices and growth, and the financial sector is looking at these adjustments carefully. For FY27, the RBI has raised its inflation projection to 5.2% from 5.0%. Core inflation which excludes food and fuel, is expected at 4.4%.
The growth forecast has also been revised. RBI now expects GDP growth of 7.1% in FY27, as against 6.7% in its earlier projection. A stronger growth expectation together with higher inflation makes an early return to rate cuts less likely, and this is the main reason savers are reconsidering their deposit and fund holdings.
Inflation numbers in the near term are higher than the full year figure. According to the reports, inflation is projected to average 6.0% in October to December 2026, which sits at the top of RBI’s tolerance band. For the period from October 2026 to June 2027, the average is projected at about 5.8%.
When a person has kept money in a bank FD, these projections matter directly. If inflation stays near the top of the range, the real return on a deposit, meaning the interest earned after subtracting the price rise, becomes slimmer. A lot of families now compare the interest on their deposits with the increase in household expenses.
Banks normally revise their deposit rates whenever the policy rate is changed, but the new rates do not take effect on the same day for all banks, and they do not apply to deposits already opened. If a senior person has a deposit from last year, he will keep earning the old rate till that deposit matures and is renewed. New deposits and renewals will see the higher rates first.
Debt funds respond in a different manner. When the policy rate goes up, the yields on new bonds are expected to rise, and the funds will gradually hold bonds that pay more. There will also be an immediate effect on the value of the existing bonds in a fund, so the first reaction in the fund returns may not look favourable to investors. The higher yield becomes visible in returns over a longer period.
The rise in the rates for FD and debt‑fund returns is expected to happen in a slow, incremental manner instead of an immediate shift.
Bank FD rate cards, debt fund category returns and AMFI data for the period after the hike will show how far the repricing has gone.
How FDs, debt funds and arbitrage funds earn their returns
The FD yields a fixed rate that is decided on the day when the deposit is made. The rate does not alter during the maturity period, so the higher rates after the hike will apply only to those who open a fresh deposit or renew an old one.
Debt funds make money from the interest on the bonds they own and from the change in the value of those bonds. When market yields rise, the price of the bonds already in the fund drops, and the fund only gains again when it buys newer bonds that have higher coupons. The final outcome depends on the kind of bonds the fund holds and how long those bonds take to mature.
Arbitrage funds work differently. Arbitrage fund returns follow futures premiums and market volatility. The returns do not depend on whether the equity market goes up or down.
For this reason, a rise in the repo rate does not act on an arbitrage fund directly. Investors who hold these funds are watching the futures premiums and the volatility in the market, and not the rate card of any bank.
The spread is wide, showing that the annual return of an arbitrage fund can vary substantially from one year to another.
A recent reading is also available, though it is older. These figures are from a period well before the rate hike, so they can be used only as a baseline and not as a measure of what the funds are earning now.
The data for debt funds does not have any return after the rate hike, and the same is true for arbitrage funds. Consequently, at the moment we cannot tell if the January pattern has altered.
The three products are also reported differently. An FD shows a rate in advance, whereas a debt fund or an arbitrage fund shows only what it has earned in the past. Many families compare the two kinds of numbers side by side, even though one is a promised rate and the other is a record of earlier performance.
The post-tax comparison for the 30% bracket
Tax treatment differs for all the three products, and for a person in the 30% bracket this changes the comparison a lot. Interest earned from a bank FD is added to the investor’s income and taxed at the slab rate, while the returns from liquid funds are taxed at same slab rate.
Arbitrage funds are classed as equity funds for tax purposes. If a gain is held for more than one year, it is taxed as long‑term capital gains at 12.5% and this rate is not linked to the income slab of the investor.
An arbitrage fund that earns roughly 7.0% before tax yields around 6.1% after tax for a person in the 30% tax bracket, if units are held for more than one year and before cess (long-term gains at 12.5%).
An FD that gives a 7.0% rate before tax works out to be a lot simpler in terms of calculation. Nearly a third of the interest will be taken out as tax at the 30% slab, so the net return that the investor actually receives is roughly 4.9%, before we even add any cess. This net rate is lower than the arbitrage estimate, even though both the products show the same pre‑tax figure.
The difference appears just because of the manner the return is taxed. A bank FD shows its rate in advance, while an arbitrage fund displays a return that has already been earned; thus many families are now comparing a promised pre‑tax rate with a past return that is not yet adjusted for tax.
Debt funds that are taxed at the normal slab rate stand in same tax position as the FD. What really separates them is the manner in which the returns are made, via bond yields and price movements, and the repricing that will follow the hike will hit them slowly over time.
Individuals in the lower tax brackets will see a smaller difference between these products, as the slab rate applicable to them is lower. The comparison above is for the 30% bracket only.
What to watch next
The post tax figures above are based on the returns before the hike, and the repricing of deposits and debt fund yields will show in the numbers published after it.
The next reading on inflation will be followed closely. The RBI projects inflation of about 6.0% for October to December 2026, and the first official numbers for that period will show whether prices are moving along the path the RBI has described.
