Should Banks' Stress Test Results Be Disclosed? an Analysis of the Costs and Benefits


Book Description

Should Banks Stress Test Results be Disclosed? An Analysis of the Costs and Benefits reviews the theoretical literature on disclosure, tying it to the recent policy debate on whether stress-test results should be disclosed. The authors review the nature of stress tests required by the Dodd-Frank act and conducted by the Federal Reserve, an important aspect of which is the public disclosure of the results. Then, it compares the arguments for and against the disclosure of banks stress test results. While the rationale for disclosing stress test results may seem intuitive in the wake of the financial crisis, some argue that disclosing these results may actually have negative unintended consequences. Using insights from recent theoretical models, the authors provide a framework for understanding these negative unintended consequences. The authors argue that the benefits of disclosing stress-test results are clear: stress tests may uncover unique information about banks allowing both bank supervisors and market participants to exercise discipline on the bank s behavior. But because banks operate in second-best environments that are prone to externalities, there are inherent costs associated with such disclosures, and proper understanding of the sources of these costs would better inform the debate and guide regulators when designing stress tests and handling the disclosures. Should Banks Stress Test Results be Disclosed? An Analysis of the Costs and Benefits is organized as follows. After a brief introduction, Section 2 reviews the nature of stress tests and considers the unique information they provide to outsiders. Section 3 explains how disclosures of stress tests could provide regulatory and market discipline, and the positive impact such discipline may have on economic efficiency. The main section, Section 4, provides an in-depth review of the possible costs of disclosure. Building on the previous section, Section 5 shows that there are non-trivial trade-offs associated with disclosure of stress-test result, and provides several policy recommendations for regulators regarding test design and disclosure of results. Section 6 concludes by reiterating the need for the development of a framework that captures the combined effects on all banks, and the challenge this poses for academics and policy makers."




Credibility and Crisis Stress Testing


Book Description

Credibility is the bedrock of any crisis stress test. The use of stress tests to manage systemic risk was introduced by the U.S. authorities in 2009 in the form of the Supervisory Capital Assessment Program. Since then, supervisory authorities in other jurisdictions have also conducted similar exercises. In some of those cases, the design and implementation of certainelements of the framework have been criticized for their lack of credibility. This paper proposes a set of guidelines for constructing an effective crisis stress test. It combines financial markets impact studies of previous exercises with relevant case study information gleaned from those experiences to identify the key elements and to formulate their appropriate design. Pertinent concepts, issues and nuances particular to crisis stress testing are also discussed. The findings may be useful for country authorities seeking to include stress tests in their crisis management arsenal, as well as for the design of crisis programs.

Macroprudential Solvency Stress Testing of the Insurance Sector


Book Description

Over the last decade, stress testing has become a central aspect of the Fund’s bilateral and multilateral surveillance work. Recently, more emphasis has also been placed on the role of insurance for financial stability analysis. This paper reviews the current state of system-wide solvency stress tests for insurance based on a comparative review of national practices and the experiences from Fund’s FSAP program with the aim of providing practical guidelines for the coherent and consistent implementation of such exercises. The paper also offers recommendations on improving the current insurance stress testing approaches and presentation of results.







Stress Testing at the IMF


Book Description

This paper explains specifics of stress testing at the IMF. After a brief section on the evolution of stress tests at the IMF, the paper presents the key steps of an IMF staff stress test. They are followed by a discussion on how IMF staff uses stress tests results for policy advice. The paper concludes by identifying remaining challenges to make stress tests more useful for the monitoring of financial stability and an overview of IMF staff work program in that direction. Stress tests help assess the resilience of financial systems in IMF member countries and underpin policy advice to preserve or restore financial stability. This assessment and advice are mainly provided through the Financial Sector Assessment Program (FSAP). IMF staff also provide technical assistance in stress testing to many its member countries. An IMF macroprudential stress test is a methodology to assess financial vulnerabilities that can trigger systemic risk and the need of systemwide mitigating measures. The definition of systemic risk as used by the IMF is relevant to understanding the role of its stress tests as tools for financial surveillance and the IMF’s current work program. IMF stress tests primarily apply to depository intermediaries, and, systemically important banks.




Reverse Stress Testing in Banking


Book Description

Reverse stress testing was introduced in risk management as a regulatory tool for financial institutions more than a decade ago. The recent Covid-19 crisis illustrates its relevance and highlights the need for a systematic re-thinking of tail risks in the banking sector. This book addresses the need for practical guidance describing the entire reverse stress testing process. Reverse Stress Testing in Banking features contributions from a diverse range of established practitioners and academics. Organized in six parts, the book presents a series of contributions providing an in-depth understanding of: Regulatory requirements and ways to address them Quantitative and qualitative approaches to apply reverse stress testing at different levels – from investment portfolios and individual banks to the entire banking system The use of artificial intelligence, machine learning and quantum computing to gain insights into and address banks’ structural weaknesses Opportunities to co-integrate reverse stress testing with recovery and resolution planning Governance and processes for board members and C-suite executives Readers will benefit from the case studies, use cases from practitioners, discussion questions, recommendations and innovative practices provided in this insightful and pioneering book.




Rules of Thumb for Bank Solvency Stress Testing


Book Description

Rules of thumb can be useful in undertaking quick, robust, and readily interpretable bank stress tests. Such rules of thumb are proposed for the behavior of banks’ capital ratios and key drivers thereof—primarily credit losses, income, credit growth, and risk weights—in advanced and emerging economies, under more or less severe stress conditions. The proposed rules imply disproportionate responses to large shocks, and can be used to quantify the cyclical behaviour of capital ratios under various regulatory approaches.




Into the Great Unknown


Book Description

Stress testing has become the risk management tool du jour in the wake of the global financial crisis. In countries where the information reported by financial institutions is considered to be of sufficiently good quality, and supervisory and regulatory standards are high, stress tests can be of significant value. In contrast, the proliferation of stress testing in underdeveloped financial systems with weak oversight regimes is fraught with uncertainties, as it is unclear what the results actually represent and how they could be usefully applied. In this paper, problems associated with stress tests using weak data are examined. We offer a potentially more useful alternative, the "breaking point" method, which also requires close coordination with on-site supervision and complemented by other supervisory tools and qualitative information. Excel spreadsheet templates of the stress tests presented in this paper are provided.




Next Generation Balance Sheet Stress Testing


Book Description

This paper presents a "second-generation" solvency stress testing framework extending applied stress testing work centered on Cihák (2007). The framework seeks enriching stress tests in terms of risk-sensitivity, while keeping them flexible, transparent, and user-friendly. The main contributions include (a) increasing the risk-sensitivity of stress testing by capturing changes in risk-weighted assets (RWAs) under stress, including for non-internal ratings based (IRB) banks (through a quasi-IRB approach); (b) providing stress testers with a comprehensive platform to use satellite models, and to define various assumptions and scenarios; (c) allowing stress testers to run multi-year scenarios (up to five years) for hundreds of banks, depending on the availability of data. The framework uses balance sheet data and is Excel-based with detailed guidance and documentation.
