FRTB Models Find Salvation in US Basel III Proposal – Risk.net
US Basel III Adjustments Revive FRTB Internal Modeling Prospects
US banking regulators’ recent proposals concerning the Fundamental Review of the Trading Book (FRTB) have significantly improved the viability of the Internal Models Approach (IMA) for US banks, reversing a trend of skepticism. The changes, specifically to the Profit & Loss (P&L) attribution test and Non-Modellable Risk Factors (NMRFs), address key concerns that previously hindered widespread IMA adoption. This shift is poised to reshape risk management strategies and create demand for specialized regulatory compliance consulting services as institutions navigate the updated framework.
The initial FRTB implementation, designed to standardize market risk capital calculations, presented substantial hurdles for US banks aiming to utilize internal models. The stringent P&L attribution test, requiring banks to demonstrate a clear link between trading desk profits and losses and underlying risk factors, proved particularly challenging. Simultaneously, the treatment of NMRFs – risks difficult to model quantitatively – added complexity and capital charges. These factors led many US institutions to favor the standardized approach, despite the potential capital efficiency gains offered by IMA.
Though, the proposed revisions, released by the Federal Reserve, the Office of the Comptroller of the Currency (OCC), and the Federal Deposit Insurance Corporation (FDIC) on March 19th, offer a more pragmatic path forward. According to the official proposal documents available on the FDIC website (https://www.fdic.gov/regulations/resources/rules/proposed/2024/2024-00051-P.pdf), the adjustments to the P&L attribution test allow for greater flexibility in demonstrating the link between risk and performance. The revised approach to NMRFs reduces the capital add-ons associated with these factors, making IMA more attractive.
The P&L Attribution Test: A Critical Shift
The original P&L attribution test demanded an almost impossible level of precision, forcing banks to allocate profits and losses to specific risk factors with a degree of accuracy that was often unattainable. The modern proposal introduces a more risk-sensitive approach, acknowledging the inherent limitations of attribution modeling. “The previous framework was overly prescriptive and didn’t reflect the realities of complex trading strategies,” explains Dr. Anya Sharma, Chief Risk Officer at Crestview Capital, in a recent interview. “These changes represent a significant step towards a more practical and effective implementation of FRTB.”
This recalibration is particularly beneficial for banks with diversified trading portfolios, where attributing P&L to individual risk factors can be exceptionally difficult. The revised test allows for a more holistic assessment of risk management practices, focusing on the overall effectiveness of the internal model rather than strict adherence to granular attribution requirements. Banks are now incentivized to invest in robust model validation and governance frameworks, creating opportunities for risk management software providers specializing in model risk management.
NMRFs: Reducing the Capital Burden
The treatment of NMRFs has also undergone a significant overhaul. The original FRTB framework imposed substantial capital charges on banks for risks that could not be readily modeled, such as liquidity risk and counterparty credit risk. The proposed revisions introduce a more nuanced approach, allowing banks to utilize expert judgment and qualitative assessments to manage these risks.
This change is particularly relevant for banks with significant exposure to illiquid or complex financial instruments. According to a recent report by Deloitte (https://www2.deloitte.com/us/en/pages/financial-services/articles/frtb-implementation-challenges.html), the reduction in capital charges associated with NMRFs could free up billions of dollars in capital for US banks, enabling them to support lending and investment activities.
Impact on US Banks and the Broader Market
The implications of these changes extend beyond individual banks. A wider adoption of IMA could lead to a more accurate and risk-sensitive assessment of market risk, enhancing the stability of the financial system. However, it also necessitates significant investment in model development, validation, and data infrastructure.
“The regulatory shift doesn’t eliminate the complexity, it simply reallocates it. Banks will now need to focus on building robust internal model frameworks and demonstrating their effectiveness to regulators. What we have is a significant undertaking that requires specialized expertise and technology.”

The transition to IMA will also require banks to enhance their data management capabilities. Accurate and reliable data is essential for building and validating internal models. This creates a demand for data analytics and data governance solutions, benefiting data management solutions providers. The increased focus on model risk management will drive demand for independent model validation services.
Looking ahead, the success of the revised FRTB framework will depend on effective implementation and ongoing monitoring by regulators. Banks will need to demonstrate a commitment to sound risk management practices and a willingness to invest in the necessary infrastructure and expertise. The coming fiscal quarters will be critical as institutions assess the impact of these changes and develop their implementation strategies. The ability to navigate this evolving regulatory landscape will be a key differentiator for banks seeking to maintain a competitive edge.
