Key Questions Answered
The Reserve Bank of India issued final directions for the minimum capital requirement for market risk under Basel III, proposing the adoption of the Simplified Standardised Approach for computing risk-weighted assets across interest-rate, equity, and foreign-exchange risk classes, effective April 1, 2027.
The trading book must include all instruments classified as 'Held for Trading', and banks cannot misclassify instruments into the banking book to lower capital requirements. If they do classify such instruments, they must calculate total capital requirements before and after and maintain the difference.
Banks have the option to exclude certain structural foreign currency investments from the Net Open Position on a case-by-case basis, provided the exclusion lasts for at least six months and the exemption is recalculated quarterly.
