A rate decision in Mumbai takes months to show up in your EMI, your FD renewal and your debt fund NAV. Here is the transmission chain, step by step, with the numbers on what each 25 basis points is worth.
A repo rate decision is announced at around ten in the morning, analysed on television by ten past ten, and forgotten by lunch. Yet the actual effect on your household finances plays out over the following six to twelve months, in a specific and fairly predictable sequence.
Understanding that sequence is genuinely useful. It tells you when to lock an FD, when to negotiate a loan rate, and when a headline is simply not about you.
First, what a basis point is
A basis point is one hundredth of a percentage point. A 25 basis point cut means the rate falls by 0.25 percentage points. Rate decisions almost always move in multiples of 25 basis points, so this is the unit everything is quoted in.
What is 25 basis points worth in rupees? On a floating-rate home loan, roughly:
| Loan amount | Tenure | Approximate EMI change per 25 bps |
|---|---|---|
| Rs 25 lakh | 20 years | About Rs 400 a month |
| Rs 50 lakh | 20 years | About Rs 800 a month |
| Rs 75 lakh | 20 years | About Rs 1,200 a month |
| Rs 1 crore | 20 years | About Rs 1,600 a month |
These are illustrative figures at rates around 8.5 percent; your exact numbers depend on your rate and remaining tenure. Run them properly in the EMI calculator.
The monthly figure looks modest. The lifetime figure does not: on a Rs 50 lakh loan, 25 basis points over a full 20-year tenure is well over Rs 1.5 lakh in total interest.
The transmission chain, step by step
Step 1: The decision, day zero. The Monetary Policy Committee announces the repo rate. Alongside the number comes the stance and the commentary, which markets often care about more than the rate itself.
Step 2: Money markets, same day. Overnight and short-term money market rates adjust almost immediately, because they are directly tied to the cost of central bank liquidity.
Step 3: Bond yields, same day to a few weeks. Government bond yields reprice, though often they have already moved in anticipation. This is why bond markets sometimes barely react to an expected decision and react violently to an unexpected one.
Step 4: Debt mutual fund NAVs, immediately. Bond prices move inversely to yields, so a rate cut lifts the NAV of debt funds holding longer-duration bonds, and a hike does the opposite. Longer-duration funds move more.
Step 5: New loan rates, within weeks. Banks update the rates offered to new borrowers relatively quickly, particularly when competing for business.
Step 6: Your existing floating loan, at the next reset. Repo-linked retail loans reset on a fixed schedule, usually quarterly from the disbursal date. This is the step most borrowers do not realise exists, and it is why the change did not show up in your statement the following month.
Step 7: Deposit rates, weeks to months. Banks adjust FD rates according to how badly they need deposits. Cuts to deposit rates typically arrive faster than increases, which is a persistent asymmetry worth knowing about.
Step 8: The real economy, six to eighteen months. Consumption, credit growth and investment respond slowly. This lag is precisely why central banks act on forecasts rather than on current data.
Why transmission is incomplete
A 25 basis point cut does not translate into a 25 basis point reduction in every rate. Several frictions get in the way.
Banks protect margins. When rates fall, loan rates linked to an external benchmark must follow, but deposit rates fall at the bank's discretion. Banks generally manage this to defend their net interest margin.
Old loans are stickier. MCLR-linked and older base-rate loans reprice on the bank's own internal schedule, sometimes annually. Borrowers on these benchmarks can wait a very long time for relief.
Credit risk premiums move independently. If lending standards tighten, the risk premium added to your rate can rise even as the benchmark falls, offsetting the benefit.
Liquidity conditions matter as much as the rate. If the banking system is short of funds, the effective cost of money can stay high regardless of the headline repo rate. This is why the RBI's liquidity operations sometimes matter more than the rate decision itself.
What to do at each stage of the cycle
| If the RBI is... | Borrowers should... | Savers should... |
|---|---|---|
| Cutting rates | Check your reset date; consider switching from MCLR to EBLR; keep EMI constant to shorten tenure | Lock longer-tenure FDs before rates fall further; consider longer-duration debt funds |
| Pausing after hikes | Review your spread against new-customer rates; prepay while rates are high | Deposit rates are near cycle highs; ladder across tenures |
| Hiking rates | Prepay if you can; avoid stretching tenure to keep EMI flat | Stay short on FD tenure; roll over as rates rise |
| Pausing after cuts | Comfortable position; focus on prepayment | Rates are near cycle lows; consider whether equity or hybrid allocations fit your goals better |
The mistake most borrowers make
When rates fall, banks typically keep your EMI the same and shorten the tenure, or keep the tenure the same and reduce the EMI. Which one happens depends on the bank's default, and most borrowers never check.
Keeping the EMI constant and letting the tenure shorten is almost always the better outcome, because it closes the loan earlier and saves substantially more interest. If your bank reduces the EMI instead, you can usually request the alternative, or replicate the effect by making an annual part-prepayment equal to the difference.
The second common mistake is ignoring the spread. Banks compete hard for new customers and rarely volunteer better terms to existing ones. If your effective rate is more than about 50 basis points above what the same bank quotes new borrowers with a similar profile, you have a case to make. A conversion fee is usually far cheaper than years of a higher rate.
What savers should understand about the asymmetry
Deposit rates fall faster than they rise. When the RBI cuts, banks trim FD rates quickly because their loan income is falling. When the RBI hikes, deposit rate increases arrive more slowly and are often concentrated in specific tenure buckets designed to attract money without repricing the entire book.
The practical response is to ladder deposits rather than trying to time them, and to pay attention to those odd special-tenure schemes, which frequently carry the best rates in the bank precisely because they are targeted. Compare outcomes in the FD calculator before committing to a long lock-in.
What does not change
A rate decision is not a reason to alter your equity allocation, pause a SIP or restructure a long-term plan. Rate cycles turn every few years and a plan that only survives one interest rate environment was not a plan.
The things worth acting on are narrow and concrete: your loan benchmark, your reset date, your spread, your FD tenure and your debt fund duration. Everything else is commentary.
How to actually negotiate your loan rate
Most borrowers never try, and the ones who do usually succeed at least partially. The process is unglamorous.
- Find your current effective rate on your statement, and your benchmark and spread in the loan agreement.
- Check what your own bank advertises for new borrowers with a similar loan size and profile.
- Get a written or app-generated quote from one or two competing lenders. This is the leverage.
- Write to your bank citing the gap and the competing quote, and ask for a spread reduction or a conversion to the current benchmark.
- Compare the conversion fee against the interest saved over your remaining tenure before agreeing.
A balance transfer to another lender is the fallback, but it involves fresh processing charges, valuation, documentation and a new legal check, so it is only worth it for a meaningful gap on a large outstanding balance.
The reason this works is straightforward. Retaining an existing borrower costs a bank nothing in acquisition, so a small spread reduction is usually preferable to losing the account entirely. Banks simply do not offer it unless asked.
