Interconnectedness and Contagion Analysis: A Practical Framework


Book Description

The analysis of interconnectedness and contagion is an important part of the financial stability and risk assessment of a country’s financial system. This paper offers detailed and practical guidance on how to conduct a comprehensive analysis of interconnectedness and contagion for a country’s financial system under various circumstances. We survey current approaches at the IMF for analyzing interconnectedness within the interbank, cross-sector and cross-border dimensions through an overview and examples of the data and methodologies used in the Financial Sector Assessment Program. Finally, this paper offers practical advice on how to interpret results and discusses potential financial stability policy recommendations that can be drawn from this type of in-depth analysis.




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.




Balance Sheet Network Analysis of Too-Connected-to-Fail Risk in Global and Domestic Banking Systems


Book Description

The 2008/9 financial crisis highlighted the importance of evaluating vulnerabilities owing to interconnectedness, or Too-Connected-to-Fail risk, among financial institutions for country monitoring, financial surveillance, investment analysis and risk management purposes. This paper illustrates the use of balance sheet-based network analysis to evaluate interconnectedness risk, under extreme adverse scenarios, in banking systems in mature and emerging market countries, and between individual banks in Chile, an advanced emerging market economy.




Five Insights for Avoiding Global Collapse


Book Description

Looming environmental and social breaking points, like climate change and massive inequalities, are becoming increasingly apparent and large in scale. In this book, Gaya Herrington puts today’s key societal challenges in perspective. Her analysis, rooted in her research on a 50-year-old model of the world that forecasted the onset of global collapse right around the present time, brings some structure to what otherwise might feel like the overwhelming task of achieving genuine societal sustainability. Herrington's research, first published in 2020 in Yale‘s Journal of Industrial Ecology, went viral after it revealed empirical data tracked closely with the predictions of this world model, which was introduced in the 1972 best seller The Limits to Growth. Her book Five Insights for Avoiding Global Collapse contains an exclusive research update based on 2022 data and is written in a more personable and accessible style than the journal article. Herrington also elaborates more in this book on the many interlinkages between our economic, environmental, and social predicaments, and on what her findings indicate for future global developments. Herington lays out why “business as usual” is not a viable option for global society and identifies the root cause of this unsustainable path. Most importantly, her book teaches us what systemic changes humanity still has time to make to achieve a better tomorrow. A future in which society has transformed beyond the mere avoidance of collapse and is truly thriving. You can read more about the question if we are on the Verge of Global Collapse here.




CoMap: Mapping Contagion in the Euro Area Banking Sector


Book Description

This paper presents a novel approach to investigate and model the network of euro area banks’ large exposures within the global banking system. Drawing on a unique dataset, the paper documents the degree of interconnectedness and systemic risk of the euro area banking system based on bilateral linkages. We develop a Contagion Mapping model fully calibrated with bank-level data to study the contagion potential of an exogenous shock via credit and funding risks. We find that tipping points shifting the euro area banking system from a less vulnerable state to a highly vulnerable state are a non-linear function of the combination of network structures and bank-specific characteristics.




Risks and Vulnerabilities in the U.S. Bond Mutual Fund Industry


Book Description

This paper assesses liquidity risk for the United States (U.S.) bond mutual funds industry and performs a range of analyses to identify which fund categories are more vulnerable to distress than others, and how sales from funds can impact financial stability. We develop a new measure to identify vulnerable categories based on expected outflows labelled ‘Flows in Distress’. Overall, most U.S. mutual funds are resilient yet high yield (HY) and loan funds would face a liquidity shortfall when faced with severe redemption shocks. Combined sales from funds can have a sizeable price impact. Finally, our contagion analysis using data on fund flows and returns shows that Investment Grade (IG) corporate bonds funds, municipal bond funds and government bond funds are more likely to spread distress to other fund categories than HY, EM and loan funds. When the first type of funds experiences stress, other funds categories are likely to experience stress as well.




West African Economic and Monetary Union


Book Description

Since the 2008 Financial Sector Assessment Program (FSAP), the financial sector of the West African Economic and Monetary Union (WAEMU) has undergone major changes that have altered its risk profile. Three structural changes have played a key role since the 2008 FSAP: (i) the financial sector has grown significantly; (ii) regional banking groups have become dominant; and (iii) the high concentration of bank portfolios in sovereign exposures, which accounted for an average of 31 percent of banking assets at end-2020, are almost triple the level observed in 2004. These changes have altered the structure of systemic risks and vulnerabilities and raised the need for implementing reforms to strengthen the effectiveness of the macroprudential policy and banking supervision frameworks.




Systemic Contingent Claims Analysis


Book Description

The recent global financial crisis has forced a re-examination of risk transmission in the financial sector and how it affects financial stability. Current macroprudential policy and surveillance (MPS) efforts are aimed establishing a regulatory framework that helps mitigate the risk from systemic linkages with a view towards enhancing the resilience of the financial sector. This paper presents a forward-looking framework ("Systemic CCA") to measure systemic solvency risk based on market-implied expected losses of financial institutions with practical applications for the financial sector risk management and the system-wide capital assessment in top-down stress testing. The suggested approach uses advanced contingent claims analysis (CCA) to generate aggregate estimates of the joint default risk of multiple institutions as a conditional tail expectation using multivariate extreme value theory (EVT). In addition, the framework also helps quantify the individual contributions to systemic risk and contingent liabilities of the financial sector during times of stress.




Macroprudential Policy - An Organizing Framework - Background Paper


Book Description

MCM conducted a survey in December 2010 to take stock of international experiences with financial stability and the evolving macroprudential policy framework. The survey was designed to seek information in three broad areas: the institutional setup for macroprudential policy, the analytical approach to systemic risk monitoring, and the macroprudential policy toolkit. The survey was sent to 63 countries and the European Central Bank (ECB), including all countries in the G-20 and those subject to mandatory Financial Sector Assessment Programs (FSAPs). The target list is designed to cover a broad range of jurisdictions in all regions, but more weight is given to economies that are systemically important (see Annex for details). The response rate is 80 percent. This note provides a summary of the survey’s main findings.




Cross-Border Interbank Contagion Risk Analysis


Book Description

This Element provides a detailed overview of the structural changes in the Asia-Pacific region from the early 2000s onwards. It reviews the most relevant literature on this important topic. The following two research areas are explored: first, by deploying visual network analysis (VNA), we analyse cross-border interbank claims and liabilities of the individual countries located in the Asia-Pacific region. Such an analysis evaluates interbank exposures to systematically important banks within the specific market. The important advantage of VNA is that it allows us to examine the 'hierarchical' cross-country interbank contagion risk that seems to have been neglected in similar studies. Secondly, we evaluate the contagion risk to the individual countries spreading from the financial centres in Hong Kong, Singapore, Tokyo, New York and London. The analysis unveils links and statistical factors that could be used as a key tool for detecting the potential triggers of systemic risk.
