The Reserve Bank of India’s 2026 Directions on Market Risk signify a structural shift toward the finalization of the Basel III framework in India. The introduction of stringent boundary restrictions, punitive scalars for non-transparent/equity-like funds, and strict internal hedging rules will require Indian commercial banks to fundamentally rethink their trading book architecture. Banks must utilize the period leading up to April 2027 to upgrade treasury technology, restructure mutual fund holdings, and secure RBI approvals for internal risk transfer desks.
1. Applicable Entities & Effective Date
Based on the issued Directions, these market risk capital norms are applicable to all Commercial Banks. This specifically includes:
- Public Sector Banks (Corresponding new banks and State Bank of India).
- Private Sector Banks.
- Foreign Banks operating in India.
Exclusions: Small Finance Banks, Payments Banks, and Local Area Banks are explicitly excluded from these Directions.
Effective Date: The guidelines come into effect on April 1, 2027, though intermediate transition scalars have been in effect since April 1, 2024, providing a runway for compliance.
2. Specific Changes Required & Management Action Plans
A. Boundary Between Banking Book and Trading Book
Specific Changes Required:
The Trading Book is now strictly defined as instruments classified as ‘Held for Trading’ (HFT). Instruments under HTM, AFS, and FVTPL (non-HFT) are strictly part of the Banking Book. To prevent regulatory arbitrage, any reclassification between books that results in a lower capital requirement will trigger a mandatory Pillar 1 capital surcharge equal to the difference.
A bank holds highly volatile corporate bonds in its HFT (Trading) book, facing high market risk capital charges. The bank decides to reclassify them to AFS (Banking book) to avoid daily mark-to-market capital volatility. Under the new rules, if this move drops their total capital requirement by ₹15 crores, the bank must maintain that exact ₹15 crore difference as a disclosed Pillar 1 capital surcharge.
- Policy Revision: Revise the internal Investment Policy to strictly align trading book definitions with HFT criteria.
- System Upgrades: Configure Treasury Management Systems (TMS) to automatically calculate and lock in the Pillar 1 surcharge upon any reclassification event.
- Pre-Trade Analysis: Mandate a “Capital Impact Assessment” sign-off from the Risk Department before any instrument is allowed to be reclassified.
B. Revised Treatment of Debt Mutual Funds (MFs) and ETFs
Specific Changes Required:
Capital treatment is now granular based on underlying assets. Open-ended debt MFs/ETFs with ≥90% debt get favorable treatment (specific risk based on the underlying assets, and general market risk via standard duration method). Closed-ended funds, or funds with <90% debt, are penalized and treated on par with equity, attracting a flat 9% specific and 9% general market risk charge (Total 18% before scalars).
Bank Alpha holds ₹200 crores in a closed-ended corporate bond fund. Previously, this might have been treated purely as debt. Now, because it is closed-ended, it is treated as equity. It will attract an 18% base charge multiplied by a severe 3.5 scalar, resulting in a massive capital hit compared to holding an equivalent open-ended fund with full daily NAV transparency.
- Portfolio Audit: Immediately audit all trading book holdings of MFs and ETFs. Identify all closed-ended funds or funds failing the 90% debt threshold.
- Divestment Strategy: Liquidate or restructure holdings in non-compliant or closed-ended debt funds before the April 2027 deadline to avoid punitive capital charges.
- Data Integration: Establish API or automated data feeds with Asset Management Companies (AMCs) to fetch underlying constituent debt details, average modified duration, and NAV on a daily/monthly basis for compliance proof.
C. Internal Risk Transfers (Credit & GIRR)
Specific Changes Required:
The RBI has clamped down on unchecked internal hedging. Transferring General Interest Rate Risk (GIRR) or credit risk from the banking book to the trading book is only recognized if it is documented, perfectly matched with an external third-party hedge, and routed through a dedicated, RBI-approved ‘GIRR internal risk transfer desk’.
A bank’s retail lending arm issues 10-year fixed-rate mortgages. To hedge interest rate risk, they execute an internal swap with the bank’s own derivatives trading desk. Under the new rules, this internal swap offers zero capital relief to the banking book unless the trading desk executes an exact matching swap with an external counterparty (like another bank) and records it specifically in the GIRR desk.
- Establish GIRR Desk: Create a formally documented ‘GIRR internal risk transfer desk’ (even if notional) and immediately apply for Department of Supervision (RBI) approval.
- Process Realignment: Implement strict back-to-back trade matching rules in the trading systems. If an external hedge is not found, the system must flag that capital relief in the banking book is nullified.
- Audit Trail: Upgrade risk documentation to ensure the source of the banking book risk and the exact corresponding internal and external hedges are mapped 1:1.
D. Structural Foreign Exchange Positions & Net Open Position (NOP)
Specific Changes Required:
Banks must calculate a 9% capital charge on their Net Open Position (NOP) for Forex. However, a major relief allows banks to exclude “structural” foreign exchange positions (like capital invested in overseas branches, unremitted surplus in foreign subsidiaries) from the NOP calculation, provided the exclusion is designed to neutralize capital ratio sensitivity to exchange rate movements.
An Indian bank has a subsidiary in London with capital in GBP. If the Rupee depreciates against GBP, the INR value of the bank’s total Risk Weighted Assets (RWAs) shoots up, pushing down the CET1 capital ratio. By taking a “structural long position” in GBP and excluding it from the daily NOP capital charge, the bank protects its capital adequacy ratio from forex volatility.
- Identify Eligible Assets: Map all capital investments and unremitted surpluses in IFSC units, OBUs, and overseas branches.
- Sensitivity Modeling: Risk teams must develop quarterly models to calculate the exact amount of structural forex positions required to neutralize CET1 ratio sensitivity.
- Board Approval: Update the internal Forex Risk Management Policy to formally adopt the structural exclusion strategy and ensure all exclusions are held for a minimum of six months as per RBI mandates.
E. Simplified Standardised Approach (SSA) & Market Risk Scalars
Specific Changes Required:
The total capital requirement is the sum of Interest Rate, Equity, and Forex risks multiplied by specific scaling factors: 1.30 for Interest Rate, 3.50 for Equity, and 1.20 for Forex. Total RWAs are then calculated by multiplying this final figure by 12.5.
If a bank’s base calculated capital requirement is ₹100 crore for Interest Rate risk and ₹100 crore for Equity risk, the final regulatory requirement will be ₹130 crore for Interest Rates, but a massive ₹350 crore for Equities. This makes equity trading highly capital intensive compared to forex or debt.
- Capital Allocation Optimization: Re-evaluate Capital Allocation and Return on Risk-Adjusted Capital (RoRAC) limits for the trading desk. Shift trading limits away from high-scalar asset classes (Equities) toward lower-scalar ones (Forex/Debt).
- Parallel Runs: Immediately begin generating dual MIS reports (Current framework vs. SSA Framework) to project capital impact well before April 2027.
