On September 21, 2026, the Reserve Bank of India issued the Reserve Bank of India (Commercial Banks – Minimum Capital Requirements for Market Risk) Directions, 2026, the final version of a framework first put out for public comment as draft guidelines on February 17, 2023. The Directions align India’s market risk capital framework with the revised Basel III standards, and after nearly three and a half years between draft and final version, treasury, market risk, and capital planning teams now have a confirmed rulebook and a firm implementation date to work toward.
For banks, this is not a routine capital adequacy update. Early industry estimates around the draft guidelines suggested banks could need 15 to 20 percent more capital for market risk under the revised framework, which makes understanding exactly what changed between draft and final version, and what has already been in transition since 2024, essential reading for anyone in treasury, risk, or finance functions.
Background: From Draft to Final Directions
RBI’s move to revise market risk capital rules is part of its broader convergence of Indian bank regulation with Basel III standards.
- The draft guidelines were released on February 17, 2023, proposing adoption of the Simplified Standardised Approach for computing capital requirements for market risk under the revised Basel III framework
- RBI examined stakeholder feedback received on the draft and incorporated consequent modifications into the final Directions, with a statement on the feedback received published as an annex to the September 2026 release
- The final Directions aim to align market risk guidelines with the revised Basel III framework while ensuring simplicity of regulation and providing flexibility and ease of adoption for banks
- The Directions will take effect from April 1, 2027, giving banks a defined runway to prepare, though intermediate transition scalars have already been in effect since April 1, 2024 to support a smoother, phased transition toward the final framework
Key Changes in the Final Directions Compared to the Draft
RBI has summarised several specific areas where the final Directions differ from what was originally proposed in the 2023 draft guidelines.
- Scope of the trading book. Since RBI’s Investment Directions already provide a clearly identifiable trading book under the Held for Trading accounting sub-classification, the instructions defining the trading book have been removed from the final market risk Directions altogether, with a reference made instead to the Investment Directions. This avoids maintaining two separate, potentially inconsistent definitions of the trading book across different RBI frameworks.
- Net Open Position and forex risk capital charge. Revised instructions from the Reserve Bank of India (Commercial Banks – Prudential Norms on Capital Adequacy) Tenth Amendment Directions, 2026 have been incorporated into the final market risk Directions, bringing forex risk capital treatment in line with RBI’s most recent capital adequacy amendments.
- Specific risk capital charge for interest rate risk. The specific risk tables for interest rate risk have been revised to align with Basel Committee on Banking Supervision guidelines, which RBI notes also provides a more concise and cleaner treatment than the earlier draft approach.
- Debt mutual funds and exchange traded funds held in the trading book. The capital treatment has been revised so that capital computation is based on the underlying risk drivers of these instruments, while still maintaining sufficient regulatory guardrails, a more risk-sensitive approach than a blanket treatment.
- Specific risk capital requirement for positions hedged by credit derivatives. The instructions have been revised to include treatment for positions hedged by total return swaps, where such instruments are permitted under the Master Direction – Reserve Bank of India (Credit Derivatives) Directions.
Why This Matters for Treasury and Market Risk Teams
A capital framework change of this scale touches far more than a single compliance checkbox, it flows directly into capital planning, trading book strategy, and how banks price and structure market risk exposure.
- Treasury and trading desks need to reassess how instruments are classified into the trading book now that the definition sits entirely within the Investment Directions rather than the market risk framework itself
- Capital planning teams need to model the impact of the revised Net Open Position and forex risk capital charge alongside the Tenth Amendment Directions on Prudential Norms on Capital Adequacy, since the two frameworks are now explicitly linked
- Risk teams managing interest rate risk in the trading book need to work through the revised, BCBS-aligned specific risk tables, since these determine capital charges at a granular, instrument level
- Banks holding debt mutual funds or ETFs in the trading book need updated capital computation processes that look through to underlying risk drivers rather than applying a simpler, blanket capital charge
- Credit derivatives and hedging desks need to understand the expanded treatment for positions hedged through total return swaps, since this changes how certain hedged positions reduce specific risk capital requirements

Preparing for the April 2027 Effective Date
With intermediate transition scalars already in effect since April 2024, banks are not starting entirely from a standing start, but the final Directions still represent a meaningful step change that requires structured preparation over the roughly eighteen months of lead time.
- Institutions should map every provision of the final Directions against their current market risk capital computation processes to identify where systems, not just policy documents, need to change
- Capital adequacy reporting teams should begin parallel-run testing of the new computation methodology well before the April 2027 deadline, rather than waiting until the effective date approaches
- Given how closely this framework is now linked to the Prudential Norms on Capital Adequacy Tenth Amendment Directions and the Investment Directions, compliance and risk teams should treat these three frameworks as a connected set rather than reviewing them in isolation

Conclusion
RBI’s final Directions on Minimum Capital Requirements for Market Risk bring India’s Basel III convergence a significant step closer to completion, with April 1, 2027 now a firm date for banks to plan around. Treasury, market risk, and capital planning teams that begin mapping the specific changes, trading book scope, forex and Net Open Position charges, interest rate risk tables, fund treatment, and credit derivative hedges, against their current systems now will be far better positioned than those waiting for the deadline to approach.
