Download or read book Next Generation Balance Sheet Stress Testing written by Mr.Christian Schmieder and published by International Monetary Fund. This book was released on 2011-04-01 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Next Generation System Wide Liquidity Stress Testing written by Mr.Claus Puhr and published by International Monetary Fund. This book was released on 2012-01-01 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A framework to run system-wide, balance sheet data-based liquidity stress tests is presented. The liquidity framework includes three elements: (a) a module to simulate the impact of bank run scenarios; (b) a module to assess risks arising from maturity transformation and rollover risks, implemented either in a simplified manner or as a fully-fledged cash flow-based approach; and (c) a framework to link liquidity and solvency risks. The framework also allows the simulation of how banks cope with upcoming regulatory changes (Basel III), and accommodates differences in data availability. A case study shows the impact of a "Lehman" type event for stylized banks.
Download or read book Designing Effective Macroprudential Stress Tests written by Mr.Dimitri G. Demekas and published by International Monetary Fund. This book was released on 2015-06-30 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Giving stress tests a macroprudential perspective requires (i) incorporating general equilibrium dimensions, so that the outcome of the test depends not only on the size of the shock and the buffers of individual institutions but also on their behavioral responses and their interactions with each other and with other economic agents; and (ii) focusing on the resilience of the system as a whole. Progress has been made toward the first goal: several models are now available that attempt to integrate solvency, liquidity, and other sources of risk and to capture some behavioral responses and feedback effects. But building models that measure correctly systemic risk and the contribution of individual institutions to it while, at the same time, relating the results to the established regulatory framework has proved more difficult. Looking forward, making macroprudential stress tests more effective would entail using a variety of analytical approaches and scenarios, integrating non-bank financial entities, and exploring the use of agent-based models. As well, macroprudential stress tests should not be used in isolation but be treated as complements to other tools and—crucially—be combined with microprudential perspectives.
Download or read book Stress Testing at the IMF written by Mr.Tobias Adrian and published by International Monetary Fund. This book was released on 2020-02-05 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Macroprudential Solvency Stress Testing of the Insurance Sector written by Mr.Andreas A. Jobst and published by International Monetary Fund. This book was released on 2014-07-22 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Stress Testing and Risk Integration in Banks written by Tiziano Bellini and published by Academic Press. This book was released on 2016-11-26 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress Testing and Risk Integration in Banks provides a comprehensive view of the risk management activity by means of the stress testing process. An introduction to multivariate time series modeling paves the way to scenario analysis in order to assess a bank resilience against adverse macroeconomic conditions. Assets and liabilities are jointly studied to highlight the key issues that a risk manager needs to face. A multi-national bank prototype is used all over the book for diving into market, credit, and operational stress testing. Interest rate, liquidity and other major risks are also studied together with the former to outline how to implement a fully integrated risk management toolkit. Examples, business cases, and exercises worked in Matlab and R facilitate readers to develop their own models and methodologies. Provides a rigorous statistical framework for modeling stress test in line with U.S. Federal Reserve FRB CCAR (Comprehensive Capital Analysis Review), U.K. PRA (Prudential Regulatory Authority), EBA (European Baning Authorithy) and comply with Basel Accord requirements Follows an integrated bottom-up approach central in the most advanced risk modelling practice Provides numerous sample codes in Matlab and R
Download or read book Rules of Thumb for Bank Solvency Stress Testing written by Mr.Daniel C. Hardy and published by International Monetary Fund. This book was released on 2013-11-11 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book A New Heuristic Measure of Fragility and Tail Risks written by Mr.Nassim N. Taleb and published by International Monetary Fund. This book was released on 2012-08-01 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a simple heuristic measure of tail risk, which is applied to individual bank stress tests and to public debt. Stress testing can be seen as a first order test of the level of potential negative outcomes in response to tail shocks. However, the results of stress testing can be misleading in the presence of model error and the uncertainty attending parameters and their estimation. The heuristic can be seen as a second order stress test to detect nonlinearities in the tails that can lead to fragility, i.e., provide additional information on the robustness of stress tests. It also shows how the measure can be used to assess the robustness of public debt forecasts, an important issue in many countries. The heuristic measure outlined here can be used in a variety of situations to ascertain an ordinal ranking of fragility to tail risks.
Download or read book Credibility and Crisis Stress Testing written by Ms.Li L. Ong and published by International Monetary Fund. This book was released on 2013-08-09 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Macroprudential Stress Tests and Policies Searching for Robust and Implementable Frameworks written by Ron Anderson and published by International Monetary Fund. This book was released on 2018-09-11 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroprudential stress testing (MaPST) is becoming firmly embedded in the post-crisis policy-frameworks of financial-sectors around the world. MaPSTs can offer quantitative, forward-looking assessments of the resilience of financial systems as a whole, to particularly adverse shocks. Therefore, they are well suited to support the surveillance of macrofinancial vulnerabilities and to inform the use of macroprudential policy-instruments. This report summarizes the findings of a joint-research effort by MCM and the Systemic-Risk-Centre, which aimed at (i) presenting state-of-the-art approaches on MaPST, including modeling and implementation-challenges; (ii) providing a roadmap for future-research, and; (iii) discussing the potential uses of MaPST to support policy.
Download or read book Global Corporate Stress Tests Impact of the COVID 19 Pandemic and Policy Responses written by Mr. Thierry Tressel and published by International Monetary Fund. This book was released on 2021-08-06 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corporate sector vulnerabilities have been a central policy topic since the outset of the COVID-19 pandemic. In this paper, we analyze some 17,000 publicly listed firms in a sample of 24 countries, and assess their ability to withstand shocks induced by the pandemic to their liquidity, viability and solvency. For this purpose, we develop novel multi-factor sensitivity analysis and dynamic scenario-based stress test techniques to assess the impact of shocks on firm’s ability to service their debt, and on their liquidity and solvency positions. Applying the October 2020 WEO baseline and adverse scenarios, we find that a large share of publicly-listed firms become vulnerable as a result of the pandemic shock and additional borrowing needs to overcome cash shortfalls are large, while firm behavioral responses and policies substantially help overcome the impact of the shock in the near term. Looking forward, while interest coverage ratios tend to improve over time after the initial shock as earnings recover in line with projected macroeconomic conditions, liquidity needs remain substantial in many firms across countries and across industries, while insolvencies rise over time in specific industries. To inform policy debates, we offer an approach to a triage between viable and unviable firms, and find that the needs for liquidity support of viable firms remain important beyond 2020, and that medium-term debt restructuring needs and liquidations of firms may be substantial in the medium-term.
Download or read book Bank Solvency and Funding Cost written by Mr.Stefan W. Schmitz and published by International Monetary Fund. This book was released on 2017-05-15 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents new evidence on the empirical relationship between bank solvency and funding costs. Building on a newly constructed dataset drawing on supervisory data for 54 large banks from six advanced countries over 2004–2013, we use a simultaneous equation approach to estimate the contemporaneous interaction between solvency and liquidity. Our results show that liquidity and solvency interactions can be more material than suggested by the existing empirical literature. A 100 bps increase in regulatory capital ratios is associated with a decrease of bank funding costs of about 105 bps. A 100 bps increase in funding costs reduces regulatory capital buffers by 32 bps. We also find evidence of non-linear effects between solvency and funding costs. Understanding the impact of solvency on funding costs is particularly relevant for stress testing. Our analysis suggests that neglecting the dynamic features of the solvency-liquidity nexus in the 2014 EU-wide stress test could have led to a significant underestimation of the impact of stress on bank capital ratios.
Download or read book Powering the Digital Economy Opportunities and Risks of Artificial Intelligence in Finance written by El Bachir Boukherouaa and published by International Monetary Fund. This book was released on 2021-10-22 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the impact of the rapid adoption of artificial intelligence (AI) and machine learning (ML) in the financial sector. It highlights the benefits these technologies bring in terms of financial deepening and efficiency, while raising concerns about its potential in widening the digital divide between advanced and developing economies. The paper advances the discussion on the impact of this technology by distilling and categorizing the unique risks that it could pose to the integrity and stability of the financial system, policy challenges, and potential regulatory approaches. The evolving nature of this technology and its application in finance means that the full extent of its strengths and weaknesses is yet to be fully understood. Given the risk of unexpected pitfalls, countries will need to strengthen prudential oversight.
Download or read book Introduction to Applied Stress Testing written by Martin Cihák and published by International Monetary Fund. This book was released on 2007-03 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress testing is a useful and increasingly popular, yet sometimes misunderstood, method of analyzing the resilience of financial systems to adverse events. This paper aims to help demystify stress tests, and illustrate their strengths and weaknesses. Using an Excel-based exercise with institution-by-institution data, readers are walked through stress testing for credit risk, interest rate and exchange rate risks, liquidity risk and contagion risk, and are guided in the design of stress testing scenarios. The paper also describes the links between stress testing and other analytical tools, such as financial soundness indicators and supervisory early warning systems. Furthermore, it includes surveys of stress testing practices in central banks and the IMF.
Download or read book Basel IV written by Martin Neisen and published by John Wiley & Sons. This book was released on 2018-07-26 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Spain written by International Monetary Fund and published by International Monetary Fund. This book was released on 2012-06-08 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the findings of the Financial Sector Assessment Program (FSAP) Update for Spain. Although there is a core of strong banks that are well managed and appear resilient to further shocks, vulnerabilities remain. Substantial progress has been made in reforming the former savings banks, and the most vulnerable institutions have either been resolved or are being restructured. Recent measures address the most problematic part of banks’ portfolios. Moving ahead, a further restructuring and recapitalization of some of the remaining weaker banks may be needed as a result of deteriorating economic conditions.
