What strategies for optimizing capital requirements can we pursue within the framework of FRTB model validation?
FRTB model validation offers considerable potential for strategic capital optimization beyond pure compliance. An advanced validation approach can directly contribute to reducing capital requirements while simultaneously improving risk management. Capital optimization potential through model validation: Internal vs. standardized models: The difference between internal models and the standardized approach can account for 30–50% of capital requirements depending on the portfolio – successful validation is therefore a direct capital efficiency lever. NMRF optimization: Non-Modellable Risk Factors can account for up to one-third of total capital requirements. Reducing them through improved validation methods and data strategies offers considerable optimization potential. Risk aggregation effects: Validating correlation assumptions and diversification effects can significantly influence capital efficiency, as these feed directly into the Expected Shortfall calculation. Backtesting add-on factors: Avoiding backtesting exceedances through more solid models directly reduces regulatory multipliers and thus capital requirements. ADVISORI's capital optimization framework: Multidimensional capital impact analysis: We develop detailed simulation models that quantify and compare the capital impact of various validation strategies and model designs.
How can we address the regulatory challenges of Expected Shortfall (ES) validation under FRTB?
Validating Expected Shortfall (ES) under FRTB presents a particular methodological challenge, as ES – unlike VaR – cannot be directly validated through simple backtesting. This complexity requires effective approaches that both meet regulatory requirements and ensure model solidness.
📉 Core challenges of ES validation:
•
Lack of direct verifiability: ES, as the average of losses beyond the VaR, cannot be validated by simply counting exceedances as is possible with VaR.
•
Stress period integration: Incorporating stress periods into the ES calculation requires specific validation approaches for stress period identification and calibration.
•
Tail risk sensitivity: The increased sensitivity of ES to tail risks requires particular attention to the validation of tail distributions.
•
Liquidity horizons: The differentiated liquidity horizons in the FRTB ES model impose additional validation requirements, particularly for less liquid risk factors.
