Bank Hits Amber Zone: H2 2025 Breaches Trigger Capital Add-on

Groupe BPCE recorded three value-at-risk backtesting breaches in the second half of 2025, pushing the bank into the amber zone under Basel III’s internal models approach and increasing its market risk capital requirements.

The breaches occurred on October 29, December 5 and December 29, 2025, when hypothetical losses — measured before intra-day position changes — exceeded the bank’s value-at-risk estimates.

BPCE attributed the breaches to interest rate moves, according to the bank’s internal analysis disclosed in regulatory reporting.

The incidents placed the bank in the “amber zone” under the Basel III framework, which triggers a presumptive increase in the capital multiplier applied to its market risk models, thereby raising the overall capital add-on for market risk.

Under the internal models approach, banks are permitted to use their own value-at-risk models to calculate capital requirements, subject to strict backtesting rules. Regulators assess model performance by comparing hypothetical profit and loss outcomes against the bank’s own risk estimates over a rolling window.

When a bank records four or more backtesting exceptions over a 250-day period, it enters the “red zone,” indicating a serious model deficiency. Three exceptions place it in the “amber zone,” which still results in a higher capital multiplier but allows time for remediation before potential model disqualification.

The increase in capital requirements directly affects the bank’s risk-weighted assets for market risk, which in turn influences its overall capital ratios under the Basel III framework.

Groupe BPCE, France’s second-largest banking group by balance sheet size, operates across retail, corporate and investment banking divisions, with significant market-making activities in fixed income, currencies and commodities that are subject to market risk capital rules.

The bank has not disclosed the specific size of the capital add-on increase resulting from the amber zone classification, nor has it provided a timeline for when it expects to reduce the number of exceptions through model recalibration or other remedial actions.

Regulatory filings and supervisory dialogues with the European Central Bank and the Autorité de Contrôle Prudentiel et de Résolution are ongoing regarding the bank’s market risk model performance and planned improvements.

As of the reporting date in April 2026, Groupe BPCE remains subject to heightened supervisory scrutiny over its internal models approach for market risk, with the amber zone status requiring enhanced reporting and potential constraints on model usage until performance improves.
