Summary:
RBI's revised bank leverage ratio rules, effective April 1, 2027, tighten exposure calculations for derivatives, securities financing and off-balance sheet commitments. Minimum capital requirements remain unchanged, but banks may need to reassess their balance sheets, capital buffers and exposure management.
The Reserve Bank of India (RBI) has announced new norms on leverage ratio for commercial banks, which will come into effect from April 1, 2027. The new framework makes it harder for banks to calculate their total exposures and hold capital against potential losses. New rules make stricter the treatment of derivatives, securities financing transactions and off-balance sheet commitments. The minimum leverage ratio requirements remain the same.
Leverage Ratio – What it Is and Why it Matters
The leverage ratio measures a bank’s tier 1 capital relative to its total exposures, which comprise loans, investments and certain off-balance sheet commitments.
The capital adequacy ratio (CAR) assigns lower risk weights to safer assets, while the leverage ratio does not take into account the risk of different assets.
The formula is simple:
Leverage Ratio = ( Tier 1 Capital / Total Exposure ) * 100
Suppose a bank has tier 1 capital of ₹10,000 crore and total exposure of ₹2,00,000 crore. Then, the leverage ratio would be 5%.
A higher ratio generally means that the capital cushion is larger relative to total exposure. This measure will also help to prevent excessive leverage build-up in banks even when their assets have relatively low regulatory risk weights.
What is new in RBI’s Leverage Ratio guidelines?
The RBI’s final directions, issued on October 23, 2026, align the Indian framework with the Basel Committee’s leverage ratio standard of 2017.
Minimum requirements remain unchanged.
| Bank Category | Minimum Leverage Ratio |
| Domestic Systemically Important Banks (D-SIBs) | 4.00 |
| Other commercial banks | 3.5% |
| Indian branches of Global Systemically Important Banks (G-SIBs) | 3.5% + applicable buffer |
The changes are mostly related to how banks measure their exposure.
The new framework will require banks to capture a broader range of derivatives, securities financing transactions and off-balance sheet exposures.
Banks with international presence or having derivatives outstanding of ₹25,000 crore and above will have to adopt the Standardized Approach for Counterparty Credit Risk (SA-CCR).
Other banks can choose between SA-CCR and the Current Exposure Method (CEM).
Collateral and offsetting arrangements to reduce reported exposure are prohibited, except where specifically permitted.
Banks are required to disclose their leverage ratios on a consolidated and standalone basis quarterly.
Impact of Revised Rules on Indian Banking
Banks with large derivatives and off-balance sheet exposures could see higher reported exposures under a more rigorous calculation framework.
If Tier 1 capital is unchanged, a higher exposure figure reduces the leverage ratio.
Those banks operating close to the minimum requirement will therefore have to raise capital, cut exposures or change their balance sheets.
But the effect will be different at each institution.
The calculation of exposure may be more affected for large banks with significant trading and derivatives business than for banks whose business is mainly traditional lending.
The framework is applicable for big listed banks like State Bank of India (NSE: SBIN, BSE: 500112), HDFC Bank (NSE: HDFCBANK, BSE: 500180) and ICICI Bank (NSE: ICICIBANK, BSE: 532174).
How Do the New Rules Affect Banking Stocks?
The revised leverage ratio framework does not necessarily mean lower profitability.
The effect on finances will depend on the capital cushion, derivatives exposure and balance sheet structure of individual banks.
A bank with higher leverage ratios may have more capacity to grow its loan portfolio without having to raise more capital.
For shareholders, the key indicators will be changes in reported leverage ratios, capital requirements, credit growth and return on equity (ROE).
There hasn’t been a specific move in banking stocks directly tied to the final rules.
The implementation deadline is April 2027, giving banks time to get their systems and capital plans in order. The revised framework aims to enhance financial stability and better align leverage exposures with transparency.
