How the Repo Rate Moves Your Home Loan EMI: EBLR, Reset Dates and the Spread
If your home loan is linked to the repo rate, a change by the RBI reaches your interest rate at the loan's next reset, which the rules cap at three months. The repo rate has stood at 5.25% since December 2025, after 125 basis points of cuts in 2025. But unless you ask, most banks keep your EMI unchanged and shorten or lengthen the tenure instead.
Key takeaways
- Repo-linked loans move fastest. Since 1 October 2019, new floating-rate retail loans from banks have had to use an external benchmark, usually the repo rate, and reset at least once every three months.
- Your rate is repo plus a spread. SBI's benchmark, for example, is the repo rate plus 2.65%, or 7.90% today; your own spread for risk sits on top and is locked at sanction.
- Older loans lag. MCLR loans usually reset every six or twelve months, and housing finance companies price off their own prime rates.
- The EMI does not fall on its own. By default banks keep the EMI and shorten the tenure after a cut, which saves more interest but leaves your monthly outgo unchanged.
- New rules are coming. RBI draft directions from August 2026 would make every floating-rate loan reset within three months from 1 April 2027.
How the repo rate reaches your loan
The RBI's September 2019 circular made all new floating-rate retail and MSME loans from banks link to an external benchmark from 1 October 2019. The benchmark could be the repo rate, a Treasury bill yield or another FBIL benchmark; for home loans, banks overwhelmingly use the repo. The circular also required the rate to be reset at least once in three months.
Your rate is built in layers. The bank sets an external benchmark lending rate, the EBLR, which is the repo rate plus a margin for its costs. SBI's, for instance, is repo plus 2.65%, which puts it at 7.90% with the repo at 5.25%. The bank then adds or subtracts a credit-risk spread for you, based largely on your credit score, as covered in our guide to the credit score banks want for a home loan. When the repo moves, only the first layer moves.
When the bank can change the spread
The spread is fixed at sanction, with two exceptions under the RBI's rules. The credit-risk premium can change only if your credit assessment changes substantially, as agreed in the loan contract. Other components, such as operating cost, could change once in three years. From 1 October 2025 the RBI also let banks cut those other components earlier, for customer retention and in a non-discriminatory way. That is a door for you to push on: a borrower whose score has improved can ask for a lower spread rather than switching banks.
EBLR, MCLR and housing finance company loans compared
Not every loan follows the repo rate so directly. At the end of December 2024, 61% of banks' floating-rate loans were linked to an external benchmark and 36% to MCLR, and the mix differs sharply by lender type.
| Loan type | What it tracks | How often it resets | How fast a repo cut arrives |
|---|---|---|---|
| Bank EBLR loan (since October 2019) | Repo rate plus the bank's margin plus your spread | At least every three months | Within about three months |
| Bank MCLR loan (taken before October 2019) | The bank's own marginal cost of funds | Usually every six or twelve months | Only as far as the bank's MCLR falls, and only at your reset date |
| Housing finance company loan | The lender's own prime lending rate | When the lender changes its prime rate | At the lender's discretion |
The lag shows up in the data. Over FY26 the repo fell 125 basis points, but a Bank of Baroda study found the weighted average rate on fresh loans fell 93 basis points, and on fresh housing loans 92. Transmission was fastest where EBLR loans dominate: about 94% of foreign banks' loans and 89% of private banks' were EBLR-linked, against about 51% at public sector banks.
Worked example: a Rs 50 lakh loan through a 125 basis point cut
Assume a Rs 50 lakh loan over 20 years, taken when the repo was 6.50%, at a total rate of 9.00% (a combined margin and spread of 2.50%). The EMI is Rs 44,986. For simplicity, assume the full 125 basis points of cuts reach the loan after one year, taking the rate to 7.75%. After 12 EMIs the outstanding balance is about Rs 49.06 lakh, with 228 months left.
| What happens | EMI | Remaining term | Total interest over the loan |
|---|---|---|---|
| No rate cut (9.00% throughout) | Rs 44,986 | 228 months | About Rs 57.97 lakh |
| Cut taken as a lower EMI | Rs 41,175 | 228 months | About Rs 49.28 lakh |
| Cut taken as a shorter tenure (bank default) | Rs 44,986 | About 190 months | About Rs 40.56 lakh |
Taking the cut as a lower EMI frees Rs 3,811 a month and saves about Rs 8.7 lakh of interest against no cut. Keeping the EMI and letting the tenure shrink ends the loan about three years and three months early and saves roughly Rs 17.4 lakh, twice as much. Real cuts arrive in steps, so actual savings are somewhat lower.
The same arithmetic runs in reverse. On a Rs 50 lakh, 20-year loan, each 25 basis points is worth about Rs 770 a month. If rates rise and your bank extends the tenure to hold the EMI, the extra months arrive quietly at the end of the loan.
Why banks change the tenure instead of the EMI
Changing the tenure needs no new mandate from you and keeps the EMI your salary already covers. That is why SBI and others default to keeping the EMI unchanged and shortening the tenure after a cut; on a hike the same default stretches the tenure instead.
The RBI stepped in with its August 2023 reset framework for EMI-based floating-rate loans, applied to existing and new loans from 31 December 2023. Under it, the lender must:
- tell you at sanction that the EMI or tenure may change with the benchmark, and tell you at each reset what changed;
- let you choose a higher EMI, a longer tenure, or a mix, and let you prepay in part or in full at any time;
- make sure a longer tenure does not cause negative amortisation, where the EMI no longer covers the interest;
- give you a quarterly statement showing principal and interest recovered, the EMI, EMIs left and the annualised rate.
The 2023 framework also required lenders to offer a switch to a fixed rate at reset. Since the October 2025 amendment that switch is at the lender's discretion, within limits set by its board policy, so do not count on it being available.
Converting an older loan
If you are still on MCLR, a base rate or an HFC's prime rate, check what your current rate is against what the same lender charges new EBLR borrowers of your profile. Banks usually allow a switch to their repo-linked product for a conversion fee set in their schedule of charges. If your own bank's offer is poor, a balance transfer to another lender may save more, after processing, legal and valuation costs.
The picture may change. In August 2026 the RBI issued draft Interest Rates on Loans and Advances Directions, 2026, meant to harmonise loan pricing across banks and other regulated lenders. As drafted, every floating-rate loan would reset within three months from 1 April 2027, MCLR would be calculated on a three-month moving average of fresh funding costs, and existing floating-rate loans would move to the new structure by 1 April 2029 with the borrower's consent, without extra fees or a higher rate. Comments closed on 11 September 2026; the final rules may differ.
Risks and who should think twice
- Repo-linked loans pass on hikes just as fast. A borrower on a tight budget feels a rising cycle within a quarter.
- A low benchmark does not mean a low rate. A wide spread can make an EBLR loan dearer than a well-priced MCLR loan.
- A lower EMI is not free. Taking a cut as a lower EMI costs the extra interest shown above; decide it against what else the money would earn, as our note on prepaying against investing sets out.
- Silence means the default. If you do nothing at a reset, the bank's default applies.

Frequently asked questions
How soon will an RBI repo rate cut reduce my home loan rate?
On a repo-linked (EBLR) loan from a bank, the change reaches you at the next reset, which must come at least once every three months. On an MCLR loan it waits for your six- or twelve-month reset date, and on a housing finance company loan it depends on when that lender moves its prime rate.
Why did my EMI stay the same after the repo rate fell?
Most banks apply a rate cut by keeping the EMI and shortening the remaining tenure. Your interest rate did fall, but the saving shows up as fewer months left to pay. If you would rather have a lower EMI, write to the bank and ask for the EMI to be recalculated over the existing tenure.
Is it better to reduce the EMI or the tenure after a rate cut?
Reducing the tenure saves far more interest. On a Rs 50 lakh, 20-year loan moving from 9.00% to 7.75% after a year, a lower EMI saves about Rs 8.7 lakh against no cut, while keeping the EMI saves about Rs 17.4 lakh and ends the loan over three years early. Take the lower EMI only if you need the monthly cash.
Can my bank raise my spread during the loan?
Only in limited cases. The credit-risk premium can change only if your credit assessment changes substantially, as your contract provides. Other spread components could change once in three years, and since October 2025 banks may reduce them earlier. A bank cannot simply widen your spread because rates have fallen. If your score has improved, ask for a lower spread.
Should I move my old MCLR home loan to a repo-linked rate?
Usually yes if the new rate, after the conversion fee, is lower than what you pay now and you expect rates to hold or fall. Compare your current rate with what the bank charges new EBLR borrowers of your profile. If the gap is small, weigh the RBI's draft rules, which would move existing floating loans to a common structure by April 2029.
