The Retreat from Risk Modeling: A Looming Shift in Financial Regulation
The financial industry is witnessing a notable pullback from complex internal models for market risk, a trend gaining momentum as regulatory scrutiny intensifies. This shift, impacting banks globally, raises questions about the future of risk management and the potential consequences for market capacity and stability.
FRTB’s Unfulfilled Promise and the Rise of Standardized Approaches
The Fundamental Review of the Trading Book (FRTB) framework, intended to overhaul market risk regulation, is facing headwinds. Instead of widespread adoption of internal models, many institutions are opting for standardized approaches. This represents driven by the increasing cost and complexity of maintaining and validating these models, coupled with a more cautious stance from regulators.
Canada’s Cold Shoulder to Internal Models
Canada provides a clear example of this trend. Authorities are demonstrating a preference for standardized approaches, signaling a broader reluctance to embrace the intricacies of internal modeling. This decision impacts how Canadian banks manage market risk and aligns with a global move towards simpler, more transparent methodologies.
FSB Concerns and the Basis Trade
The Financial Stability Board (FSB) has recently expressed concerns regarding leveraged basis trading, particularly its potential to contribute to market volatility, as highlighted by events in the US Treasury market. However, the industry appears to disagree with the extent of the FSB’s concerns, anticipating that tougher haircut regulations could restrict market capacity as debt issuance rises.
Haircuts and Market Capacity: A Delicate Balance
The debate centers around haircuts – the percentage reduction applied to the value of collateral. Increased haircuts, intended to mitigate risk, could inadvertently reduce the amount of leverage available in the market, potentially hindering liquidity and increasing transaction costs. This is a key point of contention between regulators and industry participants.
Non-Cash Variation Margin Gains Traction
Amidst these regulatory shifts, there’s growing support for the utilize of non-cash variation margin. This approach could offer greater flexibility and efficiency in managing collateral, potentially alleviating some of the pressures associated with stricter haircut requirements.
CCP Resolution Toolboxes: A Call for Prudence
Regulators are as well being urged to exercise caution when expanding the tools available for resolving central counterparties (CCPs). An overly complex toolbox could introduce new risks and uncertainties, potentially undermining the stability of the financial system.
The Impact on Risk Management
The move away from internal models necessitates a re-evaluation of risk management strategies. Institutions will need to invest in robust standardized approaches, enhance data quality and strengthen their understanding of market dynamics. This shift also emphasizes the importance of stress testing and scenario analysis.
