Starting October 1, 2026, the RBI mandates daily disclosure of bulk deposit interest rates by 10:10 am. Banks are expected to utilize this deadline to protect their pricing strategies. This move aims to standardize wholesale funding costs, but it may also heat up competition for large deposits as banks adjust to new liquidity rules based on the Liquidity Coverage Ratio.
Starting October 1, 2026, the banking sector will see a shift in how bulk deposit interest rates are published. The Reserve Bank of India has mandated that banks must disclose their daily interest rates for bulk deposits—typically defined as deposits of ₹3 crore and above—by 10:00 am each day. To allow for operational adjustments, the central bank has provided a grace period ending at 10:10 am.
This new rule is creating a strategic dilemma for treasury teams at various banks. Industry participants expect that most institutions will wait until the final minute of the 10:10 am grace period to upload their rates. The primary concern is that disclosing rates earlier would tip their hand to competitors. If a bank publishes a rate early, rivals could instantly undercut that offer by five to ten basis points, effectively stealing the deposit. By withholding the information until the deadline, banks hope to maintain a temporary advantage in securing large corporate or institutional funds.
The regulatory update also ties deposit pricing more closely to the Liquidity Coverage Ratio, a metric that measures a bank's ability to survive a 30-day stress scenario. The RBI has introduced specific run-off rates for different types of depositors. For instance, deposits from non-financial entities like charitable trusts and partnerships are treated with a 40 percent run-off rate, meaning they are considered less likely to be withdrawn all at once during a stress event. In contrast, deposits from other financial institutions, banks, and insurance companies attract a 100 percent run-off rate because they are viewed as more volatile.
Because non-financial entities have a lower run-off rate, banks are expected to offer higher interest rates on these bulk deposits to attract the funds. This framework is designed to help banks manage their wholesale funding more efficiently and reduce the ability of large depositors to manipulate pricing between competing institutions. For the banking sector, this shift signifies a move toward more transparent but potentially more competitive deposit gathering.
For investors, the immediate impact on profit margins remains to be seen. While the rule increases transparency, it also forces banks to be more disciplined in their treasury operations. Investors may track how this affects the Net Interest Margin, or the difference between interest earned and interest paid, as banks navigate this new disclosure requirement. Monitoring how deposit growth trends evolve after the October 1 deadline will be essential to understanding which banks are managing their liquidity costs most effectively under these tighter regulatory conditions.
