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.

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.

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.

This book uses perspectives of finance and banking to offer predictions on future financial crises, and how we can prepare for them.

The objective of this paper is to present an integrated tool suite for IFRS 9- and CECL-compatible estimation in top-down solvency stress tests. The tool suite serves as an illustration for institutions wishing to include accounting-based approaches for credit risk modeling in top-down stress tests.

This paper updates the IMF’s work on general principles, strategies, and techniques from an operational perspective in preparing for and managing systemic banking crises in light of the experiences and challenges faced during and since the global financial crisis. It summarizes IMF advice concerning these areas from staff of the IMF Monetary and Capital Markets Department (MCM), drawing on Executive Board Papers, IMF staff publications, and country documents (including program documents and technical assistance reports). Unless stated otherwise, the guidance is generally applicable across the IMF membership.

The global financial crisis has placed the spotlight squarely on bank stress tests. Stress tests conducted in the lead-up to the crisis, including those by IMF staff, were not always able to identify the right risks and vulnerabilities. Since then, IMF staff has developed more robust stress testing methods and models and adopted a more coherent and consistent approach. This paper articulates the solvency stress testing framework that is being applied in the IMF’s surveillance of member countries’ banking systems, and discusses examples of its actual implementation in FSAPs to 18 countries which are in the group comprising the 25 most systemically important financial systems (“S-25”) plus other G-20 countries. In doing so, the paper also offers useful guidance for readers seeking to develop their own stress testing frameworks and country authorities preparing for FSAPs. A detailed Stress Test Matrix (STeM) comparing the stress test parameters applie in each of these major country FSAPs is provided, together with our stress test output templates.

Model selection and forecasting in stress tests can be facilitated using machine learning techniques. These techniques have proved robust in other fields for dealing with the curse of dimensionality, a situation often encountered in applied stress testing. Lasso regressions, in particular, are well suited for building forecasting models when the number of potential covariates is large, and the number of observations is small or roughly equal to the number of covariates. This paper presents a conceptual overview of lasso regressions, explains how they fit in applied stress tests, describes its advantages over other model selection methods, and illustrates their application by constructing forecasting models of sectoral probabilities of default in an advanced emerging market economy.

The New York Times bestseller "Blinder's book deserves its likely place near the top of reading lists about the crisis. It is the best comprehensive history of the episode... A riveting tale." - Financial Times One of our wisest and most clear-eyed economic thinkers offers a masterful narrative of the crisis and its lessons. Many fine books on the financial crisis were first drafts of history—books written to fill the need for immediate understanding. Alan S. Blinder, esteemed Princeton professor, Wall Street Journal columnist, and former vice chairman of the Federal Reserve Board, held off, taking the time to understand the crisis and to think his way through to a truly comprehensive and coherent narrative of how the worst economic crisis in postwar American history happened, what the government did to fight it, and what we can do from here—mired as we still are in its wreckage. With bracing clarity, Blinder shows us how the U.S. financial system, which had grown far too complex for its own good—and too unregulated for the public good—experienced a perfect storm beginning in 2007. Things started unraveling when the much-chronicled housing bubble burst, but the ensuing implosion of what Blinder calls the “bond bubble” was larger and more devastating. Some people think of the financial industry as a sideshow with little relevance to the real economy—where the jobs, factories, and shops are. But finance is more like the circulatory system of the economic body: if the blood stops flowing, the body goes into cardiac arrest. When America’s financial structure crumbled, the damage proved to be not only deep, but wide. It took the crisis for the world to discover, to its horror, just how truly interconnected—and fragile—the global financial system is. Some observers argue that large global forces were the major culprits of the crisis. Blinder disagrees, arguing that the problem started in the U.S. and was pushed abroad, as complex, opaque, and overrated investment products were exported to a hungry world, which was nearly poisoned by them. The second part of the story explains how American and international government intervention kept us from a total meltdown. Many of the U.S. government’s actions, particularly the Fed’s, were previously unimaginable. And to an amazing—and certainly misunderstood—extent, they worked. The worst did not happen. Blinder offers clear-eyed answers to the questions still before us, even if some of the choices ahead are as divisive as they are unavoidable. After the Music Stopped is an essential history that we cannot afford to forget, because one thing history teaches is that it will happen again.
