25 bps RBI repo rate hike could add ₹2.45 lakh to home loan interest over 25 years; here's the calculation

A 25 bps increase in the RBI repo rate could lift borrowing costs for customers whose home loans are linked to changing benchmark rates. The example provided considers a Rs 50 lakh home loan with a 25 year tenure. If the 0.25% policy rate increase is passed through fully, the monthly instalment could rise by about Rs 817, while total interest over the loan period could increase by nearly Rs 2.45 lakh. The actual effect is not specified and would depend on lender pricing and loan terms.

The immediate market relevance lies in how quickly banks and housing finance companies transmit a higher policy rate to borrowers. Faster transmission may support lending yields, but it could also reduce housing affordability, slow mortgage demand and pressure residential property sales. Banks, housing finance companies, property developers and housing linked building materials sectors are therefore exposed. Evidence of higher loan rates, rising instalments and weaker mortgage or housing demand would confirm this reading. It would be weakened if lenders absorb the increase, transmission remains limited, or borrowers offset higher rates through changes in loan tenure or repayment terms.
