Basel Rules Force Banks to Rethink Profit and Capital

Banks are entering what one Chief Risk Officer described as a “regulatory revolution,” as the implementation of Basel 3.1 forces institutions to reassess how they price risk, allocate capital, and structure their portfolios.

“It is a compromise, but it is also a transformation,” said the CRO at a European bank. “The level of complexity we are facing is unprecedented, and it requires strategic decisions at every level of the organization.”

The upcoming reforms introduce a range of changes that will fundamentally alter how banks measure and manage risk.

Among the most significant is the output floor, which limits the extent to which internal models can reduce capital requirements.

While intended to improve consistency and comparability, it also reduces flexibility for banks that have invested heavily in advanced modeling capabilities.

The CRO explained that this shift is forcing institutions to reconsider the value of their internal models. Maintaining these models comes with significant operational costs, and the benefits are now constrained by regulatory limits. As a result, some banks are evaluating whether to simplify their approaches or move toward standardized methods.

“At some point, you have to ask whether the investment still makes sense,” she said. “That is not just a technical question, but a strategic one.”

Another key challenge lies in the treatment of credit risk, particularly in real estate portfolios.

Differences in property valuation methodologies across jurisdictions create inconsistencies in risk-weighted assets, making it difficult for banks to achieve a uniform approach.

The CRO noted that this requires a detailed reassessment of portfolios, including segmentation and assumptions.

Pricing is also coming under increased scrutiny. As capital requirements rise, banks must ensure that pricing reflects the true cost of risk. This creates tension between maintaining competitiveness and preserving profitability.

“Pricing is directly linked to capital,” the CRO said. “If you get it wrong, you either lose business or destroy value.”
