A one-sided honeymoon
Every time the RBI cuts the repo rate, a familiar pattern plays out. Borrowers with floating-rate loans start seeing their EMIs or tenures shrink within a quarter. Depositors, on the other hand, watch their FD renewal rates crawl down slowly, sometimes over six to nine months. This isn't a conspiracy by banks to favour borrowers -- it's a structural feature of how Indian bank balance sheets are built, and understanding it changes how you should time your loan and deposit decisions.
Why loans move faster: the EBLR link
Since October 2019, RBI has mandated that all new floating-rate retail loans -- home, auto, and most personal loans -- be linked to an External Benchmark Lending Rate (EBLR), usually the repo rate itself, plus a spread. Banks must reset these loans at least once every three months. So when the repo rate falls by 25 or 50 basis points, your loan's benchmark falls almost immediately, and the reset happens within one quarter automatically. There's no negotiation, no branch visit needed -- it's contractual.
Older loans, especially those still on MCLR (Marginal Cost of Funds based Lending Rate) from before 2019, move slower because MCLR itself is calculated from the bank's cost of funds, which includes deposits raised at older, higher rates. If you have an MCLR-linked home loan, you may notice your rate barely budges even after a big repo cut -- that's why many borrowers are still switching to repo-linked loans today.
Why deposits move slower: the stock vs flow problem
A bank's deposit book is a stock of money locked in at rates fixed when each FD was opened. A 3-year FD booked in 2023 at 7.5% keeps earning 7.5% until maturity, regardless of what RBI does in 2025. Only new deposits and renewals get the fresh, lower rate. Since deposits typically have tenures of 1-5 years, it can take several years for an entire deposit book to fully "catch up" with a rate change.
Loans, especially repo-linked ones, don't have this lag because the reset clause is built into the loan agreement itself. This asymmetry is sometimes called incomplete monetary policy transmission, and RBI's own research repeatedly flags it as one of the reasons rate cuts don't always boost the economy as fast as intended.
- Repo-linked loans: reset every 3 months, near-full pass-through
- MCLR loans: reset every 6-12 months, partial pass-through
- Fresh/renewed FDs: adjust almost immediately to new offered rates
- Existing FDs: locked at old rate till maturity, zero immediate pass-through
What this means if you're a borrower
If you have a repo-linked home or personal loan, a rate cut is close to instant good news. Your bank must inform you of the reduced rate and, depending on your agreement, will either lower the EMI or shorten the tenure while keeping EMI the same. It's worth actively asking your bank which option applies, since many borrowers default into "same EMI, shorter tenure" without realising it -- which is actually the better wealth-building choice if you can afford the current EMI comfortably.
If you're still on an older MCLR loan, a repo cut is a good trigger to call your bank and ask for a conversion to repo-linked pricing. Banks usually charge a small one-time conversion fee, but if the spread difference is more than 0.25-0.5%, it pays back quickly over a 15-20 year loan.
What this means if you're a saver
The flip side is that in a falling rate cycle, your existing FDs are actually more valuable than a fresh one booked today -- because you're locked into a higher rate while the market resets lower. This is exactly why FD laddering (already covered in the strategy that spreads maturities across time) works so well: it ensures you're never forced to renew your entire corpus at the bottom of a rate cycle.
If you're planning a large FD and RBI signals more cuts ahead, it may make sense to lock in a longer tenure now rather than wait, since the rate you get today is likely higher than what will be on offer in six months. Conversely, in a rising rate cycle, shorter tenures let you re-lock at higher rates sooner.
The bank's margin angle
It's worth noting this asymmetry isn't accidental from the bank's perspective either. Banks earn a spread (net interest margin) between what they pay depositors and what they charge borrowers. When loan rates fall faster than deposit rates, that margin briefly compresses -- which is one reason banks are often not in a hurry to cut deposit rates quickly, even on fresh FDs. It typically takes a couple of quarters of sustained low rates, along with softer credit demand, before banks meaningfully cut fresh FD rates to protect margins.
This is also why bank stock analysts watch the "transmission lag" closely -- a longer lag before deposit rates fall is actually good for near-term bank profitability, even though it's not great news for depositors.
A practical takeaway
Don't expect your EMI and your FD renewal rate to move in lockstep -- they're governed by completely different mechanisms. As a borrower, check whether you're on repo-linked or MCLR pricing, and push for a switch if you're paying more than you should. As a saver, use rate-cut cycles as a cue to lock in longer FD tenures before rates drift lower, and treat any existing high-rate FD as an asset worth holding onto rather than breaking early.
