Borrowers often find different interest rates on home loans despite similar credit profiles. The discrepancy typically stems from lender-determined 'spreads' rather than the benchmark repo rate. With the RBI issuing draft guidelines in August 2026 to improve pricing transparency, borrowers should understand how risk assessments and loan vintage influence their final cost.
Home loan borrowers often assume that if the Reserve Bank of India (RBI) repo rate remains constant, their interest rates should be uniform. However, it is common to find two borrowers with similar profiles paying different interest rates at the same bank. This variation primarily happens because banks do not just track the external benchmark rate; they layer it with a lender-determined margin, commonly referred to as the 'spread.'
The Mechanics of the Spread
Every floating-rate home loan is priced using a simple formula: External Benchmark Rate plus the Bank Spread. While the benchmark rate—often tied to the RBI repo rate—is the same for everyone, the spread is highly customizable. Banks use this spread to manage their profit margins and account for the specific risk they associate with each loan. Consequently, two loans may have the same benchmark foundation but different final interest rates because the underlying spread varies based on the bank's internal risk assessment at the time of origination.
Factors Influencing Your Rate
Banks do not rely solely on credit scores to set this spread. While a high CIBIL score is a prerequisite for favorable terms, lenders also evaluate the Loan-to-Value (LTV) ratio, which is the amount borrowed relative to the property's market value. A higher LTV typically signals more risk for the lender, which may result in a higher interest rate premium. Additionally, the borrower's employment category—such as salaried versus self-employed—and income stability play significant roles.
Timing is another crucial factor. Banks frequently adjust their internal pricing policies based on liquidity, competitive pressure, and broader market conditions. A loan sanctioned two years ago might have been priced under a completely different institutional spread regime than a loan taken today. This means existing borrowers may sometimes find themselves stuck with an older, less competitive spread structure, while new customers get better terms.
Regulatory Outlook
The Reserve Bank of India is actively working to bring more clarity to this segment. In August 2026, the regulator released draft directions aimed at standardizing how banks define and communicate these loan-pricing formulas. The goal is to ensure that the methodology for applying spreads is more transparent and less subject to arbitrary changes by lenders. For investors and borrowers, this shift highlights the importance of monitoring not just the headline repo rate, but also the specific spread negotiated with the bank.
Moving forward, the key monitorable for home loan customers will be how banks adjust their spreads in response to these new regulatory draft guidelines. Borrowers should remain aware that the spread is negotiable and can often be reviewed based on improvements in their credit profile or by exploring balance transfer options if their current rate is significantly higher than market standards.
