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.

The turmoil in financial markets that resulted from the 2007 subprime mortgage crisis in the United States indicates the need to dramatically transform regulation and supervision of financial institutions. Would these institutions have been sounder if the 2004 Revised Framework on International Convergence of Capital Measurement and Capital Standards (Basel II accord)—negotiated between 1999 and 2004—had already been fully implemented? Basel II represents a dramatic change in capital regulation of large banks in the countries represented on the Basel Committee on Banking Supervision: Its internal ratings–based approaches to capital regulation will allow large banks to use their own credit risk models to set minimum capital requirements. The Basel Committee itself implicitly acknowledged in spring 2008 that the revised framework would not have been adequate to contain the risks exposed by the subprime crisis and needed strengthening. This crisis has highlighted two more basic questions about Basel II: One, is the method of capital regulation incorporated in the revised framework fundamentally misguided? Two, even if the basic Basel II approach has promise as a paradigm for domestic regulation, is the effort at extensive international harmonization of capital rules and supervisory practice useful and appropriate? This book provides the answers. It evaluates Basel II as a bank regulatory paradigm and as an international arrangement, considers some possible alternatives, and recommends significant changes in the arrangement.

Basel II is a global regulation, and financial institutions must prove minimum compliance by 2008 The authors are highly sought-after speakers and among the world’s most recognized authorities on Basel II implementation Accompanying CD-ROM includes spreadsheet templates that will assist corporations as they implement Basel II

In the last decade rating-based models have become very popular in credit risk management. These systems use the rating of a company as the decisive variable to evaluate the default risk of a bond or loan. The popularity is due to the straightforwardness of the approach, and to the upcoming new capital accord (Basel II), which allows banks to base their capital requirements on internal as well as external rating systems. Because of this, sophisticated credit risk models are being developed or demanded by banks to assess the risk of their credit portfolio better by recognizing the different underlying sources of risk. As a consequence, not only default probabilities for certain rating categories but also the probabilities of moving from one rating state to another are important issues in such models for risk management and pricing. It is widely accepted that rating migrations and default probabilities show significant variations through time due to macroeconomics conditions or the business cycle. These changes in migration behavior may have a substantial impact on the value-at-risk (VAR) of a credit portfolio or the prices of credit derivatives such as collateralized debt obligations (D+CDOs). In Rating Based Modeling of Credit Risk the authors develop a much more sophisticated analysis of migration behavior. Their contribution of more sophisticated techniques to measure and forecast changes in migration behavior as well as determining adequate estimators for transition matrices is a major contribution to rating based credit modeling. Internal ratings-based systems are widely used in banks to calculate their value-at-risk (VAR) in order to determine their capital requirements for loan and bond portfolios under Basel II One aspect of these ratings systems is credit migrations, addressed in a systematic and comprehensive way for the first time in this book The book is based on in-depth work by Trueck and Rachev

Developing economies can strengthen their financial systems by implementing the main elements of global regulatory reform. But to build an effective prudential framework, they may need to adapt international standards taking into account the sophistication and size of their financial institutions, the relevance of different financial operations in their market, the granularity of information available and the capacity of their supervisors. Under a proportionate application of the Basel standards, smaller institutions with less complex business models would be subject to a simpler regulatory framework that enhances the resilience of the financial sector without generating disproportionate compliance costs. This paper provides guidance on how non-Basel Committee member countries could incorporate banks’ capital and liquidity standards into their framework. It builds on the experience gained by the authors in the course of their work in providing technical assistance on—and assessing compliance with—international standards in banking supervision.

The long-awaited, comprehensive guide to practical credit risk modeling Credit Risk Analytics provides a targeted training guide for risk managers looking to efficiently build or validate in-house models for credit risk management. Combining theory with practice, this book walks you through the fundamentals of credit risk management and shows you how to implement these concepts using the SAS credit risk management program, with helpful code provided. Coverage includes data analysis and preprocessing, credit scoring; PD and LGD estimation and forecasting, low default portfolios, correlation modeling and estimation, validation, implementation of prudential regulation, stress testing of existing modeling concepts, and more, to provide a one-stop tutorial and reference for credit risk analytics. The companion website offers examples of both real and simulated credit portfolio data to help you more easily implement the concepts discussed, and the expert author team provides practical insight on this real-world intersection of finance, statistics, and analytics. SAS is the preferred software for credit risk modeling due to its functionality and ability to process large amounts of data. This book shows you how to exploit the capabilities of this high-powered package to create clean, accurate credit risk management models. Understand the general concepts of credit risk management Validate and stress-test existing models Access working examples based on both real and simulated data Learn useful code for implementing and validating models in SAS Despite the high demand for in-house models, there is little comprehensive training available; practitioners are left to comb through piece-meal resources, executive training courses, and consultancies to cobble together the information they need. This book ends the search by providing a comprehensive, focused resource backed by expert guidance. Credit Risk Analytics is the reference every risk manager needs to streamline the modeling process.

This Detailed Assessment of Compliance on the Basel Core Principles for Effective Banking Supervision on Switzerland discusses that significant portions of guidance and legislation related to qualitative risk management and control standards are not as detailed or comprehensive as in many other major countries and need to be updated and selectively strengthened. Supervisory risk assessments and guidance to auditors, as the extended supervisory arm of the Swiss Financial Market Supervisory Authority (FINMA), need to be further materially improved, beyond what is now envisioned. Additional skilled resources within FINMA are necessary to meet these goals and to conduct more on-site supervisory work. The responsibilities and objectives of FINMA that emphasize protecting creditors, investors and insured persons, as well as ensuring proper functioning of the financial market, should be clearly stated in legislation as pre-eminent. It is recommended to increase FINMA resources, especially for on-site inspection and risk expertise. Clarify and limit the cases in which the Board can become involved in supervisory decisions and improve conflict code.
