How Repo-Rate Changes Affect Loans and Deposits

Arjun's EMI did not change and his tenure did

The rate went up, and Arjun braced for a larger instalment that never arrived. He assumed he had been lucky, or that his loan was somehow insulated.

Some months later he noticed that his loan now had rather more instalments left than it should have. Nothing had been hidden from him — a letter had explained it — but nobody had asked him which of the two he would prefer, and the default had been chosen for him.

That is the practical consequence of a policy rate change for most borrowers, and almost nobody examines it. Understanding how the change reaches a loan at all is what makes it visible.

What the repo rate is

The repo rate is the rate at which the central bank lends to commercial banks against securities, for short periods. It is the principal lever of monetary policy and it works by changing what money costs banks.

When it rises, short-term funding becomes more expensive for banks and they pass that on: lending rates rise, and eventually deposit rates follow. When it falls, the reverse — though not symmetrically and not at the same speed.

The reason a policy rate matters to a household is that it sits at the base of a chain ending at Arjun's EMI and his deposit statement. The chain has several links, and the delay and slippage at each is where the confusion lives.

Whether your loan moves at all

Whether a change reaches a loan depends on how that loan's rate is defined, and this is the single most useful thing to know about your own borrowing.

Many retail loans in India are now linked directly to an external benchmark such as the repo rate. When the benchmark moves, the loan rate moves with it at the next reset, mechanically and quickly. The spread over the benchmark, set at sanction based on your credit assessment, does not change.

Older loans are often linked to a bank's own cost-based benchmark, where transmission is slower and less complete, because the bank's internal cost changes more gradually than the policy rate does. Borrowers on these often find that cuts arrive late and small. And fixed-rate loans do not move at all during the fixed period, which is the point of them.

If you do not know which of these describes your loan, that is the thing to find out, because it determines whether a policy change is news for you at all. It is stated in your loan agreement and your bank can confirm it.

The reset is what changes your payment

A benchmark change does not alter the EMI the moment it is announced. It applies at the loan's next reset date, which is periodic rather than continuous.

Then comes a choice, and it is usually made by default rather than by the borrower. When the rate rises, banks commonly hold the EMI constant and extend the tenure instead. That feels painless and is not — you pay for longer, and the additional interest over a long loan can be substantial. Some lenders will let you increase the EMI and keep the tenure instead.

It is worth knowing which your lender did, and asking for the alternative if you would prefer it. This is what happened to Arjun, and it is the part of a rate change that most borrowers never examine.

Why deposit rates lag

Deposit rates respond too, usually more slowly and often less completely — particularly when rates are falling, when lending rates tend to come down faster than deposit rates do.

There are two structural reasons. Banks compete for deposits, so cutting deposit rates risks losing them. And a large part of a bank's deposit base sits in existing fixed deposits contractually locked at the old rate until they mature, so the bank's funding cost only changes as those roll over.

For a saver this produces the asymmetry people notice and resent, where loan rates seem to rise promptly and deposit rates seem to rise reluctantly. The mechanism is real and is not solely a matter of banks being unhelpful.

What it does to bonds and debt funds

The policy rate is not the only rate that matters, since bond prices respond to the whole structure of market rates and, crucially, to expectations of where policy is heading.

Two consequences surprise people. Bond markets move before the announcement, because the market anticipated it — so by the time a change is made, much of it may already be in prices, and a widely expected cut can be followed by no move at all, or by a move in the opposite direction if the accompanying commentary was less dovish than hoped.

And long rates need not move with short rates. A change in the policy rate is a short-rate event, while long-dated bonds respond more to expectations about inflation and growth over many years, which is why a rate cut sometimes leaves long bonds unmoved or falling.

For a debt fund holder the implication is that duration determines the size of the response, and that the response is to market rates rather than mechanically to the policy announcement.

What to actually do

Find out how your loan is priced — which benchmark, what spread, what reset frequency. If you are on an older internally benchmarked loan, ask what it would take to move to an externally benchmarked one and what that would cost, since during a falling-rate period the difference can be worth real money.

Decide EMI against tenure deliberately. When a rise hits, ask your lender which they applied and whether you can choose the other, because the default is not always the one you would pick.

Do not restructure a portfolio on a rate announcement, because by the time you act the market has. Horizon matching — duration set against when you need the money — is designed precisely so that rate moves are something you do not have to trade around.

For deposits, watch the rate cycle rather than the announcement. If rates look likely to fall, locking a longer deposit fixes today's rate; if they look likely to rise, shorter deposits let you reinvest sooner. That is a judgement about an uncertain future, so keep it modest — a tilt rather than a forecast.

And note that prepayment becomes more attractive as rates rise. Prepaying a loan is a guaranteed return equal to the loan's rate, and that guaranteed return rises with the loan rate. This is one of the few cases where a rate change genuinely should prompt a household decision, and it is one worth considering rather than accepting a longer tenure by default.

What to take away

The policy rate reaches your loan through your loan's benchmark, at its reset date, and reaches your deposits more slowly because the bank's existing deposits are locked at old rates.

Find out which benchmark prices your loan and how often it resets, since that determines whether an announcement affects you at all. When a rise arrives, decide consciously between a higher EMI and a longer tenure. And leave the investment portfolio alone, because bond markets have usually moved before the announcement and matching duration to horizon removes the need to react.
