In many respects, the “London whale” scandal at JPMorgan Chase is similar to other “rogue trading” events, in that a group of traders took large, speculative positions in complex derivative securities that went wrong, resulting in over US$6 billion of trading losses to the firm. As in other rogue trading cases, there were desperate attempts to cover up the losses until they became too big to ignore and eventually had to be recognized in the financial accounts of the bank. However, the whale case, so-called because of the sheer size of the trading positions involved, differs in several important respects from other rogue trading cases, not least because the sheer size and riskiness of the positions were well-known to many executives within JPMorgan, a firm that prided itself on having advanced risk management capabilities and systems. The role of Model Risk in this scandal, while not the primary cause, is important in that at least part of the impetus to take huge positions was due to incorrect risk modeling. Various external and internal inquiries into the events have concluded that critical risk management processes in the bank broke down, not only in the Chief Investment Office, the division in which the losses occurred, but across the bank. In particular, deficiencies in the firm’s Model Development and Approval processes allowed traders to trade while underestimating the risks that they were running. Under Basel II regulations, losses due to process failure are classified as operational risk losses and hence this case demonstrates a significant failure of operational risk management in JPMorgan. This paper dissects the whale scandal from an operational risk perspective using the late Professor Barry Turner’s framework for analyzing organizational disasters. The paper also makes suggestions as to how model risk may be managed to prevent similar losses in future.
期刊介绍:
In December 2017, the Basel Committee published the final version of its standardized measurement approach (SMA) methodology, which will replace the approaches set out in Basel II (ie, the simpler standardized approaches and advanced measurement approach (AMA) that allowed use of internal models) from January 1, 2022. Independently of the Basel III rules, in order to manage and mitigate risks, they still need to be measurable by anyone. The operational risk industry needs to keep that in mind. While the purpose of the now defunct AMA was to find out the level of regulatory capital to protect a firm against operational risks, we still can – and should – use models to estimate operational risk economic capital. Without these, the task of managing and mitigating capital would be incredibly difficult. These internal models are now unshackled from regulatory requirements and can be optimized for managing the daily risks to which financial institutions are exposed. In addition, operational risk models can and should be used for stress tests and Comprehensive Capital Analysis and Review (CCAR). The Journal of Operational Risk also welcomes papers on nonfinancial risks as well as topics including, but not limited to, the following. The modeling and management of operational risk. Recent advances in techniques used to model operational risk, eg, copulas, correlation, aggregate loss distributions, Bayesian methods and extreme value theory. The pricing and hedging of operational risk and/or any risk transfer techniques. Data modeling external loss data, business control factors and scenario analysis. Models used to aggregate different types of data. Causal models that link key risk indicators and macroeconomic factors to operational losses. Regulatory issues, such as Basel II or any other local regulatory issue. Enterprise risk management. Cyber risk. Big data.
