Home loan rates: how a repo-linked EMI actually moves, and what you can do about it
Since 2019 most floating retail loans track an external benchmark. That changed what happens to your loan when rates move — usually to your tenure rather than your EMI.
If you took a floating-rate home loan from a bank after October 2019, it is almost certainly linked to an external benchmark rather than to the bank's internal cost of funds. In practice that benchmark is usually the RBI's repo rate. Understanding the mechanics is worth real money over twenty years.
How your rate is built. Benchmark plus a spread. The spread has two parts: a mark-up the bank sets for its own margin, and a credit risk premium based on your profile — chiefly your credit score, income stability and the loan-to-value ratio. The bank can change the credit risk premium only on a material change in your credit profile, and the operating margin only in the manner its policy permits. The benchmark portion resets at least once a quarter.
What happens when the benchmark moves. The rate on your loan changes at the next reset. What lenders have historically done by default is hold the EMI constant and extend the tenure. That feels painless and is not: on a loan with many years left, a rate rise absorbed entirely by tenure can add years to the loan and a great deal of interest. In extreme cases the EMI stops covering the interest accrual entirely and the balance grows.
You have a choice, and the lender must offer it. Following an RBI circular in 2023, lenders are required to communicate a rate reset to the borrower and to give the option of switching to a fixed rate, increasing the EMI, extending the tenure, or a combination, along with disclosure of the charges and the impact of each. If your rate has moved and nobody has asked you which you prefer, ask. Choosing to raise the EMI instead of the tenure is usually the cheaper path if the cash flow allows.
Prepayment is free on floating loans. The RBI has barred banks and housing finance companies from levying foreclosure charges or prepayment penalties on floating-rate term loans sanctioned to individual borrowers for non-business purposes. Fixed-rate loans can carry a charge. This means part-prepayment on a floating home loan is a genuinely available lever — and prepaying early in the tenure, when the interest component of each EMI is at its largest, removes disproportionately more interest than the same amount prepaid later.
How much you can borrow. Two limits bind. The loan-to-value ratio caps the loan against the property value on a slab basis, so a larger purchase requires a proportionately larger down payment. Separately, the lender sizes the EMI against your net monthly income; a comfortable total EMI outgo is generally taken well under half of it, and existing loans count.
What to do once a year. Check the rate you are actually paying against what the same lender is offering new borrowers. If the gap is meaningful, ask for a conversion to the current spread — most lenders will do it for a fee, which is often recovered within months. Compare that against the cost of a full balance transfer to another lender, including the processing fee and fresh legal and valuation charges.
Rates and regulations change. Confirm the current position with the RBI's own notifications or with your lender before acting.
