Developing a systemic liquidity stress testing tool is challenging due to data constraints and hard-to-model behavioral factors. There has yet to be a uniformly accepted model partly because the nature of systemic liquidity risks differs significantly across countries. This paper offers a simple Excel-based tool to assess the high-level impact of aggregate liquidity stress on the whole economy and gauge its spillover across banks, non-bank financial institutions (NBFIs), and non-financial economic sectors. It primarily uses the balance sheet approach (BSA) data—a sector-aggregate matrix of financial exposure by counterpart—that have become increasingly available for various economies with all income levels. The results can identify systemically important financial linkages to be analyzed further and help calibrate macroprudential measures and a liquidity support framework. When liquidity stress stems from capital outflows, the tool can enrich policy discussion based on integrated policy framework (IPF) and international reserve adequacy perspectives.

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.

We developed a novel Systemwide Liquidity (SWL) framework to identify liquidity stress in the system that goes beyond banks and to assess the role played by non-bank financial institutions (NBFIs) in episodes of liquidity stress. The framework, which complements standard liquidity and interconnectedness analyses, traces the flow of liquidity among various agents in the economy and explores possible transmission channels and amplification mechanisms of correlated liquidity shocks. The framework uses unique balance sheet and asset encumbrance data to demonstrate the importance of assessing liquidity at the system level by allowing for (i) analyses of each agent’s contribution to liquidity stress, (ii) analyses of the impact of different behavioral assumptions (e.g., pecking order of collateral utilization, negative externalities of fire-sales and margin positions), and (iii) policy simulations. Since this framework covers a comprehensive set of financial instruments and transactions, it paves the way for harmonization of systemwide liquidity analysis across countries. We applied this general framework to Mexico in the context of the FSAP. Results for Mexico show that commercial banks safeguard the resiliency of the financial system by backstopping the liquidity needs of other agents. Moreover, certain sectors appear more vulnerable when binding regulatory liquidity constraints trigger risk-averse behavioral responses.

The IMF has had extensive involvement in the stress testing of financial systems in its member countries. This book presents the methods and models that have been developed by IMF staff over the years and that can be applied to the gamut of financial systems. An added resource for readers is the companion CD-Rom, which makes available the toolkit with some of the models presented in the book (also located at elibrary.imf.org/page/stress-test-toolkit).

This paper reviews quantitative tools of financial stability assessments under the Financial Sector Assessment Program (FSAP). A key focus of FSAPs is on methodologies to gauge risks on a system-wide level and propose mitigating measures. Therefore, the paper concentrates on the main elements of the FSAP’s macroprudential stress testing framework:(i) the interaction among solvency, liquidity, and contagion risks in the banking sector, (ii) the assessment of the health of nonbank financial institutions (NBFIs), their interactions with banks and their impact on financial markets, (iii) the assessment of the health of nonfinancial sectors and their links to the financial sector, and (iv) macroprudential policy analysis. The paper also reviews recent improvements in microprudential bank solvency stress testing—an important foundation for the macroprudential stress testing framework—and discusses new tools for emerging risks (climate change, fintech, and cyber).

Central banks have become part of our modern life. Understanding their operations and policies is important, even to a layperson. At the core of their mission is financial stability. The stress test is one of the tools that Central Banks (or monetary authorities) use to assess how sound commercial banks are within their jurisdictions at any point in time. Bank stress testing is designed to test the resilience of banks to severe but plausible shocks. These scenarios are conceived around a fall of asset prices, a shock to interest rates, a reassessment of risk premiums or a large depreciation to correct an external imbalance. Nonetheless, passing a stress test does not provide a blind assurance that a financial institution is safe and outside the reach of collapse. This book aims to educate on the risks tested and the methods often used in stress testing. It is the first book in its field to make a comprehensive and up-to-date analysis of stress testing, including climate risk.

During two visits in 2023-24, the IMF mission implemented a set of recommendations made by a previous technical assistance mission in May 2022 which were aimed at improving the solvency stress model of the Superintendency of Banks, Panama (SBP). The mission also provided training on the design of a cash flow-based liquidity stress tool and another system-level liquidity stress testing methodology. During a follow-up mission, work was carried out on market risk and corporate risk, and the methodology for the liquidity stress test that was used during the 2023 Financial Sector Assessment Program (FSAP) with Panama was anchored at the SBP.

Bank liquidity stress testing, which has become de rigueur following the costly lessons of the global financial crisis, remains underdeveloped compared to solvency stress testing. The ability to adequately identify, model and assess the impact of liquidity shocks, which are infrequent but can have a severe impact on affected banks and financial systems, is complicated not only by data limitations but also by interactions among multiple factors. This paper provides a conceptual overview of liquidity stress testing approaches for banks and discusses their implementation by IMF staff in the Financial Sector Assessment Program (FSAP) for countries with systemically important financial sectors over the last six years.

The book covers alternative lending using the emergence of Debt Funds in the EU as a case study. The book explores the risks that they can pose to financial stability, and the regulatory and supervisory tools available to mitigate these risks. Through this analysis, the book uncovers the risks and potential risk mitigation tools that can be applied to the alternative lenders–including debt funds and other potential alternative lenders. After identifying the reasons behind the growth of alternative lenders (using as example the assets of Alternative Investment Funds (AIFs) and in particular debt funds) and the simultaneous decrease of the banks’ assets, the book analyses the systemic importance of the alternative lenders and the risk channels through which the systemic risk can spread to the banking sector and the financial system. Then, the book deals with the financial innovation-market failure theory and demonstrates that financial innovations (e.g. debt funds, securitisations) can cause market failures, resulting in regulatory interventions. Of interest to banking and financial regulation academics, researchers, and practitioners this book analyses the regulatory provisions in place for both credit institutions and debt funds, including the Basel Accords, the Capital Requirements Directives and Regulations, and the Alternative Investment Fund Managers Directive (AIFMD) and its implementation in various EU jurisdictions, before offering a proposal for a new three-defensive framework applicable to debt funds and to other potential alternative lenders.

Korea faced challenges from inflation, growth slowdown, and financial stress in the wake of the pandemic. Growth started to slow in mid-2022 as global demand for electronics waned and domestic demand weakened but has begun to gradually recover in recent quarters. Headline inflation has declined from last year’s peak, though core inflation has remained more persistent. Pockets of financial vulnerability have emerged, but swift policy measures have helped to stabilize financial and housing markets. Despite having increased, systemic financial risks appear to remain manageable.
