What an RBI rate decision actually does to your EMI

Every couple of months the Monetary Policy Committee announces a decision and the coverage translates it straight into home loans getting cheaper or dearer. The translation is real, but slower and more conditional than the headline suggests, and the details decide how much of it reaches you.

What the repo rate is

It is the rate at which the RBI lends short-term money to commercial banks. It sets the floor for the cost of funds across the banking system, which is why it works as a lever on everything else. It is not itself a rate at which anyone lends to you.

The link to your loan

Since October 2019, new floating-rate retail loans from banks have had to be tied to an external benchmark, most commonly the repo rate. Your rate is that benchmark plus a spread the bank sets, covering its margin and your credit profile. The spread is meant to stay fixed for the life of the loan unless your credit standing changes materially. That structure is why transmission is faster than it used to be, and largely automatic rather than discretionary.

Older loans priced off MCLR, and loans from housing finance companies rather than banks, follow different and generally slower mechanics.

The reset date is the part nobody mentions

External benchmark loans reset at least once every three months. A cut announced in the first week of a month does not reach a borrower whose reset falls ten weeks later until that reset arrives. The gap between announcement and instalment is normal, not a bank withholding a cut.

EMI or tenure: a choice you may not know you have

When the rate changes, a lender can hold your EMI steady and adjust the number of instalments, or hold the tenure and adjust the EMI. Indian lenders have commonly defaulted to changing the tenure, because it keeps monthly cash flow stable. It also changes the total interest you pay, and in a rising cycle a long enough extension can run past a borrower's working life — which is why the RBI has required lenders to offer borrowers the choice and to spell out the impact.

Two practical consequences. If you want to be debt-free sooner, check what your loan actually did at the last reset and ask for the EMI to absorb the change instead. If you want monthly breathing room, the default may already suit you.

What else moves, and by how much

• Fixed deposit rates, usually with a lag and rarely by the full amount.
• New personal and car loans, where the spread over the benchmark is far larger than on a home loan, so a repo move is proportionally a smaller part of the total.
• Credit card interest, essentially not at all — those rates are set by the issuer and sit far above any benchmark.

The one number to look up

Not the repo rate. Your sanction letter states the benchmark, the spread and the reset frequency. Those three lines predict your EMI more accurately than any policy coverage, and most borrowers have never read them.
