On 21 September 2026, the Reserve Bank of India issued its final RBI Basel III market risk capital rules: the Reserve Bank of India (Commercial Banks – Minimum Capital Requirements for Market Risk) Directions, 2026. The Directions take effect on 1 April 2027. They require commercial banks to calculate market risk capital using the Simplified Standardised Approach (SSA), aligned with the revised Basel III framework.
Market risk is the risk of loss when market prices move against a bank’s positions. Picture a treasury desk holding government bonds for trading. If yields rise by 50 basis points, those bonds lose value, and the bank’s capital must absorb the loss.
After the 2008 crisis, the Basel Committee on Banking Supervision (BCBS) rebuilt its market risk rules. It published the Fundamental Review of the Trading Book (FRTB) in January 2016 and revised it in January 2019. Importantly, the 2019 revision added a Simplified Standardised Approach for banks with small or non-complex trading portfolios.
The stakes were significant. According to the BCBS, the revised framework would raise total market risk capital by about 22% on a weighted-average basis, compared with Basel 2.5.
India chose a measured path. RBI released draft guidelines on 17 February 2023, proposing the SSA rather than the more complex FRTB approaches. Meanwhile, intermediate transition scalars have applied since 1 April 2024, so banks could absorb the capital impact gradually. After reviewing industry feedback, RBI issued the final Directions in September 2026, together with a statement on the comments received.
RBI’s press release lists five major changes from the 2023 draft. Each one lands on a different team inside the bank.
The final Directions drop their own trading book definition. Instead, they refer to the Investment Directions, 2025. In practice, every instrument classified as Held for Trading (HFT) sits in the trading book. By contrast, HTM, AFS and non-HFT FVTPL holdings stay in the banking book and attract credit risk capital.
This removes a potential mismatch between accounting and capital classification. Moreover, RBI has closed the door on book-switching. If a reclassification lowers a bank’s total capital requirement, the bank must hold the difference as a disclosed Pillar 1 surcharge.
The forex rules now incorporate RBI’s Tenth Amendment Directions, 2026 on capital adequacy. The capital charge is 9% of the overall Net Open Position (NOP), and forex risk applies across both the trading and banking books. However, banks gain an option to exclude structural forex positions, such as capital invested in overseas branches or subsidiaries. That exclusion is capped at the amount that neutralises the capital ratio’s sensitivity to exchange rates. It must also stay in place for at least six months.
Specific risk captures price moves driven by the issuer, rather than by general interest rates. RBI has revised these tables to match BCBS guidelines, so issuer rating and residual maturity now drive the charge. For instance, RBI’s own illustration applies 1.60% to an AA-rated corporate bond with more than 24 months to maturity.
This is arguably the biggest practical change for Indian treasuries. Qualifying debt funds now receive a look-through treatment based on their underlying holdings. To qualify, an open-ended fund must invest at least 90% of its AUM in debt, disclose full holdings and average modified duration at least monthly, and publish a daily NAV.
RBI’s worked examples show the gap clearly. A qualifying Central Government securities fund attracts zero specific risk, and its general market risk works out to roughly 4% of the investment before netting. Conversely, a ₹300 crore fund with only 88% in debt fails the test. As a result, it attracts equity-style charges of 9% plus 9%, or ₹54 crore before scalars.
Hedge recognition now covers total return swaps permitted under the Credit Derivatives Directions, 2026. A cash bond hedged by a TRS on the exact same reference obligation can receive a full offset. In contrast, a closely matched credit default swap hedge generally receives an 80% offset.
Under the SSA, a bank adds up its interest rate, equity and forex charges after applying scaling factors of 1.30, 3.50 and 1.20 respectively. It then multiplies the total by 12.5 to get risk-weighted assets. Consequently, equity-like positions become expensive, because they carry the 3.50 scalar.
The industry expected an impact from the start. In 2023, bank officials told Business Standard that the draft could raise market risk capital needs by 15–20%. At the time of writing, no estimate for the final rules has been published. Fortunately, Indian banks start from strength. RBI’s Financial Stability Report, June 2026 put the CRAR of scheduled commercial banks at 17.7% and CET1 at 15.3% at end-March 2026. Even so, capital is allocated desk by desk, so high-scalar positions will need to justify their returns.
Banks must meet the requirement continuously, at the close of each business day, on both a standalone and consolidated basis. Therefore, month-end spreadsheets will not suffice. The debt fund look-through also needs monthly holdings and duration data from AMCs, mapped to specific risk buckets. Similarly, any structural forex exclusion must be recalculated every quarter using the CET1 ratio.
Treasury heads will likely revisit how they park surplus liquidity in debt funds under HFT. Qualifying funds now cost far less capital than non-qualifying ones. At the same time, TRS-based hedges become a recognised capital tool, which widens the hedging toolkit.
| Date | Milestone |
| 17 February 2023 | RBI issues draft market risk guidelines proposing the SSA |
| 1 April 2024 | Intermediate transition scalars take effect |
| 21 September 2026 | RBI issues the final Directions |
| 1 April 2027 | Directions come into force |
In short, banks have roughly six months to move from interpretation to production-ready systems.
Basel III’s Pillar 1 sets minimum capital for three risk categories: credit risk, market risk and operational risk. A bank’s capital ratio divides its capital by the sum of all three RWA figures. So a weakness in one category reduces headroom for the others.
This is why 1 April 2027 matters so much. Three RBI frameworks take effect on the same day: these market risk Directions, the Credit Risk Standardised Approach Directions issued in April 2026, and the Expected Credit Loss Directions. In other words, Indian banks will change how they capitalise credit risk, provision for it and capitalise trading risk, all at once.
Credit risk is usually the largest component. Its building blocks are Probability of Default, Loss Given Default and Exposure at Default. Under the ECL Directions, banks model these parameters to set provisions. Staging tests such as a significant increase in credit risk then decide whether a loan carries 12-month or lifetime expected loss. Operational risk, meanwhile, moved to a Business Indicator-based approach after RBI finalised those norms in June 2023.
Consider one event: a corporate bond issuer is downgraded. The HFT bond’s specific risk charge rises. At the same time, the same borrower’s loans may move to a higher ECL stage and a higher risk weight. An analyst who understands only one framework sees a third of the picture. That is why integrated skills across Basel III credit risk requirements and market risk analytics are increasingly valued in Indian banks.
They are the Reserve Bank of India (Commercial Banks – Minimum Capital Requirements for Market Risk) Directions, 2026. These rules set how much capital banks must hold against losses from interest rate, equity and forex price movements.
They take effect on 1 April 2027. RBI issued them on 21 September 2026. Transition scalars have applied since 1 April 2024.
Partly. India has adopted the Simplified Standardised Approach, which BCBS added to the FRTB framework in 2019. Indian banks do not use the full sensitivities-based method or internal models.
They apply to commercial banks. Small Finance Banks, Payments Banks and Local Area Banks are excluded.
Qualifying open-ended funds receive a look-through treatment based on their underlying debt holdings. Funds that fail the eligibility tests are treated like equity, attracting 9% specific and 9% general market risk charges.
The final RBI Basel III market risk capital rules bring India’s trading book framework in line with global standards, while keeping the calculation deliberately simple. For banks, the next six months are about execution: HFT reconciliation, debt fund data feeds, daily capital computation and hedge documentation. For analysts, the message is equally clear. Market risk capital, credit risk capital and ECL provisioning now converge on the same April 2027 date, and employers want people who can connect all three.
