Most home loan borrowers treat their interest rate like the weather: the bank announces it, they accept it, and they get on with paying the EMI. That habit can quietly cost you lakhs over the life of the loan, and the rules that govern your rate give you more room to push back than you probably realise.
When you take a home loan, which is of floating rate, then this floating rate is made of two parts – a benchmark and a spread. For most banks, the benchmark is the RBI’s repo rate, and every floating-rate loan sanctioned after 1 October 2019 has to be linked to an external benchmark of this kind, with any change in it passed on to you. NBFCs are exempt from this requirement, so the rules differ if your lender is not a bank.
You have no say over the RBI repo rate, since the RBI decides that, but the spread is a different story. It covers the bank’s operating costs and a credit risk premium, which is essentially the price the bank puts on the chance that you will not repay, and that second component depends heavily on how you look as a borrower.
Under the RBI’s 2025 directions, the spread is left to the banks and has to follow a board-approved policy that spells out its components and the range applicable to each category of borrower. The same policy can allow a bank to reduce spread components for an existing customer even before three years are up, provided there is a justifiable reason and the benefit is given without discrimination. On the other side, the credit risk premium on an existing loan cannot be raised unless your credit profile has deteriorated or your tenor has changed.
Notice what this does and does not say. The framework permits your bank to lower your spread, but it does not oblige the bank to do so.
Consider a Rs 50 lakh home loan over 20 years. At 8.5% the EMI comes to roughly Rs 43,391, and at 7.5% it falls to about Rs 40,280, a difference of around Rs 3000 a month that adds up to nearly Rs 8 lakh across the full tenor. Very few investments hand you a guaranteed return of that size for the effort of one application and a few documents, which is why I think of a lower spread as one of the cheapest wins available to a salaried borrower.
Do not wait for the bank to call you – A better score does not bring your rate down on its own. The spread you were sanctioned reflects your profile on the day the loan was approved, and the bank has no obligation to inform you about fall in loan rates or to re-underwrite you simply because your score has since improved. Banks also review operating costs only once every three years, and the credit risk premium moves only when your profile does, so nothing happens unless you start the conversation.
Write to your lender, cite your improved score, and ask for a review of the credit risk premium. Be prepared for the bank to look at more than the score, because it will usually reassess your income, your other debts, your repayment record, the collateral and the loan-to-value ratio before deciding. If the whole picture has improved, your case is strong, but if only the number has changed, you should expect a firmer response.
Fix the score before you ask – You cannot negotiate with a number you have not checked, so begin by pulling your credit report. TransUnion CIBIL, Experian, Equifax and CRIF High Mark are all required to give you one free report a year, and it is worth going through it line by line for errors, outdated entries and accounts you do not recognise, since a mistake can drag your score down even when you have paid every bill on time.
From there, the work is mostly behavioural. Pay your EMIs and card bills on the due date, clear any overdue amounts, and resist the urge to take on personal loans or new cards you do not need. A cluster of credit applications in a short window tells a lender you are leaning heavily on credit, which is exactly the wrong signal to send before asking for a better rate.
A score improves slowly and rewards consistency over quick fixes, so the boring habits have to come first. Once your profile is clean, go back to your bank with the evidence and ask for a better spread, because the worst outcome is a no and the best one keeps paying you for years.
