The Reserve Bank of India has drawn a sharper regulatory line around how banks measure credit risk from derivatives and other complex transactions, setting a Rs 25,000 crore threshold for mandatory adoption of new risk approaches. The framework is designed to bring more sophisticated risk measurement to lenders with substantial exposure to market-linked products, while allowing smaller institutions to retain flexibility in how they assess such risks.
The rule is significant because derivatives and related dealings can create exposures that are not always captured well by conventional credit risk models. For banks with large trading books, cross-border operations or sizeable off-balance-sheet positions, the potential for losses can rise quickly when counterparties weaken or market conditions turn volatile. By tying the requirement to a clear exposure threshold, the central bank is effectively signalling that larger and more complex lenders must upgrade their internal risk systems to match the scale of their business.
Risk Threshold Set
The Rs 25,000 crore benchmark is likely to become the key dividing line in the banking system. Institutions above that level will be expected to adopt the new credit risk approaches, while those below it will have the option to use alternative measurement methods. That distinction matters because it reflects a regulatory preference for proportionality: the RBI is not imposing a one-size-fits-all rule on the entire sector, but instead calibrating compliance to the size and complexity of each bank.
In practical terms, the change should affect banks that have meaningful derivative exposure, active treasury operations or international footprints. Such lenders are more likely to face counterparty risk, valuation swings and settlement-related vulnerabilities. For them, the new framework may require changes to internal models, data systems, governance processes and supervisory reporting. It may also push banks to reassess how they price risk, allocate capital and monitor counterparties across product lines.
Bigger Banks, Bigger Scrutiny
The RBI's move comes at a time when regulators globally are paying closer attention to hidden leverage and interconnectedness in financial markets. Derivatives can be useful tools for hedging interest rate, currency and credit risks, but they can also amplify stress if exposures are poorly measured or concentrated. The central bank's decision suggests that it wants banks to be better prepared for those tail risks, especially as Indian lenders expand their participation in more sophisticated financial products.
For large banks, the new rule may also have strategic implications. Better risk measurement can improve resilience, but it can also reveal higher capital needs or force banks to reduce certain exposures. Institutions with international operations may be particularly affected because cross-border transactions often involve more complex legal, market and counterparty considerations. The threshold-based approach therefore appears aimed at the segment of the banking system most likely to generate systemic spillovers if risk is mispriced or underestimated.
Smaller Lenders Get Flexibility
For banks below the Rs 25,000 crore threshold, the RBI has left room to use alternative methods. That flexibility is important for smaller lenders, which may not have the scale, data depth or technical infrastructure needed to implement more advanced models immediately. It also reduces the risk of overburdening banks whose derivative activity is limited or largely incidental to normal lending operations.
Still, the option to use alternative methods should not be read as a relaxation of supervisory expectations. Even smaller banks will remain responsible for understanding the risks embedded in their transactions and for ensuring that their internal controls are adequate. The central bank's broader message is that risk measurement must be fit for purpose, and that institutions with greater complexity should meet a higher standard.
The new framework is likely to be watched closely by bank treasuries, risk officers and auditors, particularly as lenders prepare for any operational changes needed to comply. It also reinforces the RBI's continuing emphasis on prudential discipline at a time when financial markets are increasingly interconnected. For the banking sector, the message is clear: scale and complexity now come with a more exacting supervisory lens.
