RBI Issues Final Guidelines to Implement Basel Leverage Ratio 2017 Standard from April 2027

The Reserve Bank of India (RBI) has issued its final guidelines for commercial banks to implement the Basel Committee on Banking Supervision's (BCBS) Leverage Ratio 2017 standard. The revised rules, issued as part of the Reserve Bank of India (Commercial Banks – Prudential Norms on Capital Adequacy) Eleventh Amendment Directions, 2026, will come into force starting April 1, 2027.

This follows the central bank's draft framework released on August 7, 2026, which was open for stakeholder feedback until August 28, 2026. While industry participants had requested an extension of the compliance timeline and proposed lowering requirements for global banks to the Basel baseline of 3%, the RBI rejected both submissions, keeping its stricter prudential stance intact.

Key Thresholds Under the Final Framework

The leverage ratio serves as a non-risk-based backstop designed to constrain the build-up of excessive leverage across the banking system, calculated as a lender's Tier 1 capital divided by its total exposure measure. Under the finalised directions:

• Domestic Systemically Important Banks (D-SIBs): State Bank of India (SBI), HDFC Bank, and ICICI Bank will continue to be bound by a minimum leverage ratio requirement of 4%.
• Other Commercial Banks: All other scheduled commercial banks operating in India must maintain a minimum leverage ratio of 3.5%, well above the international Basel III baseline of 3%.
• Global Systemically Important Bank (G-SIB) Branches: Indian branches of foreign G-SIBs are mandated to maintain a 3.5% minimum leverage ratio plus the parent bank's applicable leverage ratio buffer, including any additional buffer mandated by the home regulator.

The RBI also specified that capital distribution constraints, including restrictions on the repatriation of profits, will be placed on any G-SIB branch that fails to maintain its stipulated leverage ratio buffer. The severity of the restriction will be calibrated based on the branch's Common Equity Tier 1 (CET1) risk-based ratio and leverage ratio levels.

Exposure Measure and Reporting Overhaul

The Leverage Ratio 2017 standard introduces a significantly more comprehensive and granular methodology for measuring exposures across four core categories:

• On-balance sheet assets, including derivative collaterals.
• Derivative exposures using refined counterparty credit risk valuation.
• Securities financing transactions (SFTs), such as repurchase agreements (repos) and margin lending.
• Off-balance sheet commitments, subject to specific credit conversion factors.

Under the framework, banks are generally prohibited from using physical or financial collateral, guarantees, or standard credit-risk mitigation techniques to compress their exposure measure, except where explicit carve-outs apply. In exceptional macroeconomic conditions, the RBI retains the power to temporarily exclude central bank balances from the exposure measure to facilitate monetary policy transmission.

Market and Investor Implications

For Indian equity and debt investors, the finalisation of these norms provides greater regulatory clarity for the financial sector. Indian domestic lenders generally maintain leverage ratios above the mandated thresholds, meaning immediate capital-raising pressures are expected to remain minimal. However, by establishing a non-risk-weighted floor against rapid balance-sheet expansion and tightening off-balance sheet treatment, the central bank aims to ensure that balance-sheet growth does not outstrip structural equity capital as credit demand expands. Commercial banks must now reconfigure their internal audit, risk calculation, and regulatory disclosure systems to comply ahead of the April 1, 2027 deadline.
