This article examines the impact of the new supervisory standards of Basel 2.5 and Basel III for bank trading portfolios with regards to the additional capital requirements developed to mitigate liquidity risk and credit risk. Using the incremental risk charge (IRC), the authors estimate risk measures in several alternate contexts. They find a potentially material increase in capital requirements above and beyond that concluded in the far-ranging impact studies conducted by the international supervisors. This effect is accentuated for financial or sovereign sectors as compared with industrial sectors, and regulatory capital is larger than economic capital. They compare credit risk models and find that the multivariate model reveals larger capital estimates for the financial and sovereign sectors by orders of magnitude versus the industrial sector or the Basel II model. Finally, in a Bayesian experiment, they find that the new requirements may introduce added uncertainty into risk measures as compared with existing approaches.

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value-at-Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR to measure risk and set these requirements. Assuming elliptically distributed asset returns, we show that portfolios on the mean-SCVaR frontier generally lie away from the mean-variance (M-V) frontier. In a plausible numerical example, we find that such portfolios tend to have considerably higher ratios of risk (measured by, e.g., standard deviation) to minimum capital requirement than those of portfolios on the M-V frontier. Also, we find that requirements based on SCVaR are smaller than those based on both VaR and SVaR but exceed those based on just VaR. Finally, we find that requirements based on SCVaR are less procyclical than those based on either VaR or both VaR and SVaR. Overall, our paper suggests that the use of SCVaR to measure risk and set requirements is not a panacea.

In this paper, we provide an overview of the concerns surrounding the variations in the calculation of risk-weighted assets (RWAs) across banks and jurisdictions and how this might undermine the Basel III capital adequacy framework. We discuss the key drivers behind the differences in these calculations, drawing upon a sample of systemically important banks from Europe, North America, and Asia Pacific. We then discuss a range of policy options that could be explored to fix the actual and perceived problems with RWAs, and improve the use of risk-sensitive capital ratios.

In December 2017 the Basel committee finalised its work on the reform of the Basel III framework. Together with requirements already published in 2015 and 2016, the Basel committee changes all approaches for the calculation of RWA and the corresponding Pillar III disclosure rules. This package of new standards from the Basel Committee, which is unofficially called "Basel IV", is now the most comprehensive package of modifications in the history of banking supervision. The banking industry will face major challenges in implementing these new rules. The second edition of the "Basel IV" handbook is updated with all publications up to March 2018 and also extensively enhanced with additional details, examples and case studies. The aim is to convince the reader that we are facing a new framework called "Basel IV" and not just a fine adjustment of the existing Basel III regulations. This book covers all new approaches for the calculation of RWA: - the standardised approach (CR-SA) and the IRB approach for credit risk, - the new standardised approach for counterparty credit risk (SA-CCR), - both the standardised approach and internal models approach from the "fundamental review of the trading book" (SBA and IMA) - the basic approach (BA-CVA) and standardised approach (SA-CVA) for the CVA risk, - all new approaches (SEC-IRBA, SEC-ERBA, SEC-SA, IAA) for securitisations (incl. STS), - the approaches for the calculation of RWA for equity positions in investment funds (LTA, MBA, FBA) - the new standardised approach for operational risk (SA-OpRisk) Because of the strong relation to the Pillar I requirements, the second edition covers the topics of interest rate risk in the banking book (IRRBB), large exposures and TLAC again. Additionally, the book contains a detailed description of the Pillar III disclosure requirements. With the aid of a high-profile team of experts from countries all over the globe, the complexity of the topic is reduced, and important support is offered.

At present, there is no regulatory capital requirement for the market risk exposures a bank takes in its trading account activities. Alternative approaches are being considered for setting regulatory capital requirements on such risks. One proposal would use a regulatory model for measuring such risks, while a second proposal would base market risk capital requirements on risk estimates generated by a bank's internal risk measurement model--the so-called quot;internal models approach.quot; The first of these proposals suffers from the drawback that there is currently no generally acceptable model for measuring market risks and it is questionable whether an efficient quot;regulatory standardquot; model could be developed and maintained over time. In response to criticisms of the first proposal, the quot;internal modelsquot; approach has been developed as an alternative mechanism for setting market risk capital requirements. This paper considers the difficulties inherent in using a bank's internal risk measurement model to estimate the long- horizon risk exposure that determines a regulatory capital requirement for market risk. The analysis suggests that bank internal models are not capable of measuring risk exposures over the relatively lengthy time interval of regulatory interest. Long-horizon risk exposure estimates are compromised by statistical complications surrounding time aggregation of trading portfolio returns and because operational risk measurement models do not adequately capture large options risks, nor do these risk estimates recognize the endogeneity of a bank's risk exposures. In addition to these measurement issues, verification problems plague an internal models approach. When capital requirements are based on estimates of low probability potential loss events, there is no reliable procedure that can be used to validate a bank's reported risk estimate. These results suggest that an internal models approach for setting market risk capital requirements may be less than ideal if the accuracy of risk exposure estimates and the potential for independent verification are valued aspects of the regulatory capital system.

The evolution of risk management has resulted from the interplay of financial crises, risk management practices, and regulatory actions. In the 1970s, research lay the intellectual foundations for the risk management practices that were systematically implemented in the 1980s as bond trading revolutionized Wall Street. Quants developed dynamic hedging, Value-at-Risk, and credit risk models based on the insights of financial economics. In parallel, the Basel I framework created a level playing field among banks across countries. Following the 1987 stock market crash, the near failure of Salomon Brothers, and the failure of Drexel Burnham Lambert, in 1996 the Basel Committee on Banking Supervision published the Market Risk Amendment to the Basel I Capital Accord; the amendment went into effect in 1998. It led to a migration of bank risk management practices toward market risk regulations. The framework was further developed in the Basel II Accord, which, however, from the very beginning, was labeled as being procyclical due to the reliance of capital requirements on contemporaneous volatility estimates. Indeed, the failure to measure and manage risk adequately can be viewed as a key contributor to the 2008 global financial crisis. Subsequent innovations in risk management practices have been dominated by regulatory innovations, including capital and liquidity stress testing, macroprudential surcharges, resolution regimes, and countercyclical capital requirements.

Under the new Basle Guidelines, all financial institutions subject to local banking laws will soon be required to operate under dramatically different risk exposure rules. Risk Management and Capital Adequacy provides details on the key risk approaches under these new guidelines and is the first book to analyze if and how they can be integrated. From conceptual frameworks to analyses of models and approaches, it provides a solid reference source for the information that everyone in risk management will soon need to know.
