Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a unified mathematical framework for the transmission channels for damaging shocks that can lead to instability in financial systems. As the title suggests, financial contagion is analogous to the spread of disease, and damaging financial crises may be better understood by bringing to bear ideas from studying other complex systems in our world. After considering how people have viewed financial crises and systemic risk in the past, it delves into the mechanics of the interactions between banking counterparties. It finds a common mathematical structure for types of crises that proceed through cascade mappings that approach a cascade equilibrium. Later chapters follow this theme, starting from the underlying random skeleton graph, developing into the theory of bootstrap percolation, ultimately leading to techniques that can determine the large scale nature of contagious financial cascades.

This book was released on 2018-05-15 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the interconnectedness of the global financial system and its susceptibility to shocks. A novel multilayer network framework is applied to link debt and equity exposures across countries. Use of this approach—that examines simultaneously multiple channels of transmission and their important higher order effects—shows that ignoring the heterogeneity of financial exposures, and simply aggregating all claims, as often done in other studies, can underestimate the extent and effects of financial contagion.The structure of the global financial network has changed since the global financial crisis, impacted by European bank’s deleveraging and higher corporate debt issuance. Still, we find that the structure of the system and contagion remain similar in that network is highly susceptible to shocks from central countries and those with large financial systems (e.g., the USA and the UK). While, individual European countries (excluding the UK) have relatively low impact on shock propagation, the network is highly susceptible to the shocks from the entire euro area. Another important development is the rising role of the Asian countries and the noticeable increase in network susceptibility to shocks from China and Hong Kong SAR economies.

Available in PDF, EPUB and Kindle. Book excerpt: The recent crisis has highlighted the crucial role that existing linkages among banks and financial institutions plays in channeling and amplifying shocks hitting the system. The structure and evolution of such web of linkages can be fruitfully characterized using concepts borrowed from the theory of (complex) networks. This paper critically surveys recent theoretical work that exploits this concept to explain the sources of contagion and systemic risk in financial markets. We taxonomize existing contributions according to the impact of network connectivity, bank heterogeneity, existing uncertainty in financial markets, portfolio composition of the banks. We end with a discussion of the most important challenges faced by theoretical network-based models of systemic risk. These include a better understanding of the causal links between network structure and the likelihood of systemic risk and increasingly using the empirical knowledge about real-world financial-network structures to calibrate theoretical models.

This book was released on 2019-10-11 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Network models of interbank exposures allow the mapping of the complex web of financial linkages among many institutions and address issues of system stability and contagion risk. Although existing models cover a fair amount of ground in explaining how network structure can lead to default cascades and in quantifying the likelihood and the impact of default cascades through balance-sheet mechanics, the literature has shortcomings in explaining how shocks are potentially amplified through the network of exposures. These amplification mechanisms seem to be very important in financial crises. This review discusses the main conceptual ideas behind network models of contagion, the major findings of this literature, as well as some limitations of existing models.

Book excerpt: An intricate web of claims and obligations ties together the balance sheets of a wide variety of financial institutions. Under the occurrence of default, these interbank claims generate externalities across institutions and possibly disseminate defaults and bankruptcy. Building on a simple model for the joint determination of the repayments of interbank claims, this paper introduces a measure of the threat that a bank poses to the system. Such a measure, called threat index, may be helpful to determine how to inject cash into banks so as to increase debt reimbursement, or to assess the contributions of individual institutions to the risk in the system. Although the threat index and the default level of a bank both reflect some form of weakness and are affected by the whole liability network, the two indicators differ. As a result, injecting cash into the banks with the largest default level may not be optimal.

Available in PDF, EPUB and Kindle. Book excerpt: We propose a flexible CoVaR-based measure to estimate the tail risk contagion across financial institutes in a high dimensional framework. Considering potential nonlinearity and interaction among the financial institutes, a single-index indicator representing directed spillover is derived from Gradient Boosting Machine based generalized quantile regression. Our approach can be utilized to monitor risk spillover channels for risk supervision. Empirically, we investigate 16 publicly-listed banks in China with our proposed method. We show the outperformance of our method over the linear model. The empirical study suggests that the tail risk is inclined to spill over into the same type of banks. Besides, we find that not only state-owned banks are systemically important, but small and medium banks can play key roles in tail risk contagion, too. The total connectedness peaks when the financial system is under distress.

We propose to supplement ratings with indicators of downgrade risk. To overcome some of the drawbacks of existing rating methods, we suggest a risk-based rating procedure for structured products. Finally, we formulate a series of recommendations regarding the use of credit ratings for CDOs and other structured credit instruments.

This book was released on 2017 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate systemic risk and how financial contagion propagates within the euro area banking system by employing the Maximum Entropy method. The study captures multiple snapshots of a dynamic financial network and uses counterfactual simulations to propagate shocks emerging from three sources of systemic risk: interbank, asset price, and sovereign credit risk markets. As conditions deteriorate, these channels trigger severe direct and indirect losses and cascades of defaults, whilst the dominance of the sovereign credit risk channel amplifies, as the primary source of financial contagion in the banking network. Systemic risk within the northern euro area banking system is less apparent, while the southern euro area banking system is more prone and susceptible to bank failures provoked by financial contagion. By modelling the contagion path the results demonstrate that the euro area banking system insists to be markedly vulnerable and conducive to systemic risks.
Download or read book Financial Contagion and Investor Learning written by Ritu Basu and published by International Monetary Fund. This book was released on 2002-12 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been several episodes of financial market "contagion" in the 1990s. Is contagion driven by herd behavior? Does it reflect fundamental economic linkages between countries? Or are episodes of contagion driven by investor learning and risk reassessment about a select group of countries? We pursue these questions by studying the persistence in the spillover of shocks following the bond market developments in Hong Kong SAR in 1997. Our results suggest that this contagion, at least for a few countries, was a consequence of adverse sentiment shifts arising from investor learning and was not merely driven by changes in fundamentals.

Book excerpt: I develop a model of financial networks in which linkages not only spread contagion, but also induce private sector bailouts, where liquid banks bail out illiquid banks because of the threat of contagion. Introducing this bailout possibility, I show that linkages may be optimal ex ante because they allow banks to obtain some mutual insurance even though formal commitments are impossible. However, in some cases (e.g., when liquidity is concentrated among a small group of banks), the whole network may collapse. I also characterize the optimal network size and apply the results to joint liability arrangements and payment systems.
