Decoding the RBI's New Mandate
Effective October 1, 2026, the RBI is rolling out a revised framework for how banks handle bulk deposits. In simple terms, a bulk deposit is a single fixed deposit of ₹3 crore or more, typically placed by companies, institutions, and high-net-worth individuals.
Historically, the interest rates for these large sums were often decided through private negotiations, leading to situations where two clients depositing the same amount on the same day could receive different rates. The RBI's new rules are designed to end this practice. The core mandate is twofold: enhance transparency and ensure fairness.
The End of Preferential Treatment
The new regulations explicitly state that banks cannot discriminate between depositors of a similar amount accepted on the same day. The interest rate offered must be uniform across all branches and for all customers for a deposit of the same size and tenure. To enforce this, the RBI has mandated a strict disclosure requirement. Every bank must now publish its interest rates for bulk deposits on its website every business day by 10:00 AM, with a small grace period until 10:10 AM. Whatever rate is published is the only rate that can be offered for that day. This effectively kills the back-channel negotiations that gave preferential rates to certain clients.
The Rise of the Daily Rate Check
This move towards radical transparency has a direct and immediate consequence: it shifts the competitive ground. If a bank wants to attract a large deposit from a major corporate client, it can no longer offer a private, preferential rate. Instead, it must change its publicly declared interest rate for all bulk deposits of that category for the day. This has turned the process of placing large funds into a new daily ritual for corporate treasurers and finance managers. Their new normal involves starting the day by checking the websites of multiple banks to compare the officially declared rates before deciding where to park their funds. This is the 'same-day rate check' that has suddenly become a critical part of treasury management.
Flexibility Within the Rules
While enforcing uniformity, the RBI has also given banks a new, more sophisticated tool for pricing. The rules allow banks to offer differential interest rates on bulk deposits based on their liquidity risk profile under the Liquidity Coverage Ratio (LCR) framework. In essence, the LCR framework assesses how 'sticky' a deposit is likely to be during a financial stress event. A deposit that is less likely to be withdrawn quickly (has a lower run-off rate) is more valuable to a bank. The new rules allow banks to price this stability, potentially offering a better rate for more stable funds, while still applying that rate uniformly to all deposits in that specific risk category.
A More Dynamic and Demanding Market
The combined effect of these changes is a faster, more competitive, and operationally demanding market for both banks and their largest clients. For corporate depositors, the change brings greater clarity and bargaining power, as they can easily compare public rates. For banks, it means their treasury and asset-liability management teams must be far more agile. They need to make quick decisions on daily rates based on their funding needs and market competition. While the new framework isn't expected to directly impact retail fixed deposit rates for smaller customers, it represents a significant step in making the wholesale funding market more efficient and transparent.
