The Reserve Bank of India has moved to tighten how banks measure credit risk from derivatives and other complex dealings, setting a Rs 25,000 crore threshold that will determine which lenders must adopt the new approach. The change is designed to bring larger and more sophisticated institutions under a more rigorous framework, particularly those with substantial derivatives books or cross-border operations.
Risk Rules Tightened
Under the new rule, banks with assets of Rs 25,000 crore or more will be expected to use the updated credit risk methodology. The central bank's move reflects a broader supervisory push to ensure that institutions with larger and more complex balance sheets are measuring exposures in a way that better captures the risks embedded in derivatives, structured transactions and similar instruments.
For banks below the threshold, the RBI has allowed flexibility. These lenders may continue to use alternative risk measurement methods, giving smaller institutions room to adopt frameworks that are more proportionate to their scale and business model. The distinction suggests the regulator is seeking to avoid imposing the same compliance burden on banks with limited exposure to sophisticated market products.
Focus On Complex Exposure
The rule is especially relevant for banks with considerable derivatives exposure or international presence. Such institutions typically face more varied counterparty, market and settlement risks than purely domestic lenders. By tying the requirement to size and complexity, the RBI is signalling that risk measurement must keep pace with the growing sophistication of bank balance sheets.
Derivatives have long been a focus area for regulators because they can amplify losses if exposures are not properly tracked and collateralised. In periods of market stress, even well-capitalised banks can face sudden strains if counterparties default or if hedges fail to perform as expected. The RBI's latest step appears aimed at improving the quality of risk capture before such vulnerabilities build up.
The threshold-based design also indicates a calibrated regulatory approach. Rather than mandating a single model for the entire banking system, the central bank is differentiating between institutions based on size and likely exposure profile. That could help reduce unnecessary compliance costs for smaller banks while pushing larger lenders toward more advanced risk management standards.
Implications For Banks
For major banks, the new rule may require changes in internal systems, data collection and model validation. Institutions that operate across markets or maintain active derivatives desks will likely need to review how they classify exposures, estimate credit risk and report those risks to management and supervisors. The shift may also influence capital planning, since more precise risk measurement can affect the amount of capital banks must hold against certain exposures.
The move comes at a time when Indian banks are expanding their use of treasury products and increasingly engaging with global financial markets. As balance sheets become more complex, regulators have been pressing lenders to strengthen governance, improve stress testing and build more resilient risk frameworks. The RBI's latest measure fits into that wider supervisory agenda.
For smaller banks, the option to use alternative methods may provide operational relief, but it also places the onus on management to ensure that simpler frameworks remain robust and transparent. Even where the new rule is not mandatory, the central bank's direction of travel is clear: banks are expected to demonstrate that they understand the risks they are taking, especially when those risks arise from instruments that can move quickly and unpredictably.
The threshold may also shape competitive dynamics. Larger banks with stronger systems may absorb the compliance burden more easily, while smaller lenders could retain simpler operating models for longer. Over time, however, the RBI's emphasis on risk sensitivity may encourage broader adoption of more sophisticated measurement tools across the sector.
The latest step underscores the central bank's continuing effort to align banking supervision with the realities of modern finance. In a market where derivatives and cross-border exposures are increasingly part of routine business, the RBI is drawing a clear line: the bigger and more complex the bank, the more exacting the risk framework must be.
