Bank Network Analysis In The Eccu

This paper applies network analysis to assess the extent of systemic vulnerabilities in the ECCU banking system. It includes two sets of illustrative stress tests. First, solvency and liquidity shocks to each individual bank and the impact on other banks in the network through their biltareal net asset exposures. Second, country and region-wide tail shocks to GDP affecting capital and liquidity of all banks in the shocked jurisdictions, followed by the rippling effects through the regional network. The results identify systemic institutions that merit hightened attention by the regulator, as determined by the degree of connectivity with the rest of the system, and the extent to which they are vulnerable to the failure of other banks.

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.

In this paper we explore the properties of the global banking network using cross-border bank lending data for 184 countries over 1978-2009. Specifically, we analyze financial interconnectedness using network metrics of centrality, connectivity, and clustering. We document a relatively unstable global banking network, with structural breaks in network indicators identifying several waves of capital flows. Interconnectedness rankings, especially for borrowers, are relatively volatile over the period. Connectivity tends to fall during and after systemic banking crises and sovereign debt crises. The 2008-09 global financial crisis stands out as an unusually large perturbation to the cross-border banking network.

Shortly after the financial crisis of 2007-2008 many authors began to write about certain “huge institutions” potentially able to damage the entire financial system through negative shocks, approaching the issue of systemic risk in banking through the evaluation of the so called “Too-Big-to-Fail” actors. While the size of a bank is certainly a factor of risk when considering systemic implications, this book also explores the properties of some deeply interconnected institutions. The author’s main intuition is based on the renowned work by Mark Granovetter on “The Strength of Weak Ties” and “Economic Action and Social Structure: The Problem of Embeddedness”: dangerous flows, like financial shocks, may travel very quickly through networks in unexpectedly efficient ways thanks to “Weak Ties”. The existence of weaker yet longer ties implies a naturally “robust yet fragile” network where even distant actors are closely interconnected, sharing both opportunities and risks. As a consequence, some nodes may act as key actors under the structural perspective. It is therefore critical for the central authority to identify and closely monitor said institutions. Thanks to a journey through the history of Social Network Analysis this book offers a complete overview on the evolution of the methodology and the most recent applications to systemic risk assessment, which are completed by a critical approach towards the “Too-Interconnected-to-Fail” perspective.

This global handbook provides an up-to-date and comprehensive overview of shadow banking, or market-based finance as it has been recently coined. Engaging in financial intermediary services outside of normal regulatory parameters, the shadow banking sector was arguably a critical factor in causing the 2007-2009 financial crisis. This volume focuses specifically on shadow banking activities, risk, policy and regulatory issues. It evaluates the nexus between policy design and regulatory output around the world, paying attention to the concept of risk in all its dimensions—the legal, financial, market, economic and monetary perspectives. Particular attention is given to spillover risk, contagion risk and systemic risk and their positioning and relevance in shadow banking activities. Newly introduced and incoming policies are evaluated in detail, as well as how risk is managed, observed and assessed, and how new regulation can potentially create new sources of risk. Volume I concludes with analysis of what will and still needs to happen in the event of another crisis. Proposing innovative suggestions for improvement, including a novel Pigovian tax to tame financial and systemic risks, this handbook is a must-read for professionals and policy-makers within the banking sector, as well as those researching economics and finance.

This book provides a diagnosis of the central economic and financial challenges facing Caribbean policymakers and offers broad policy recommendations for promoting a sustained and inclusive increase in economic well-being. The analysis highlights the need for Caribbean economies to make a concerted effort to break the feedback loops between weak macroeconomic fundamentals, notably pertaining to fiscal positions and financial sector strains, and structural impediments, such as high electricity costs, limited financial deepening, violent crime, and brain drain, which have depressed private investment and growth. A recurring theme in the book is the need for greater regional coordination in finding solutions to address the Caribbean’s shared and intertwined macroeconomic and structural challenges. The analysis suggests that strengthening regional and global market integration of Caribbean economies would provide an impetus to sustained growth in incomes and jobs. Greater regional and global economic integration would also facilitate structural transformation and a shift toward new economic activities, resulting in more diversified and less vulnerable economies. A central challenge for the Caribbean is thus to come together as a region, overcome the limitations posed by size, and garner the benefits of globalization. Efforts should build on existing regional arrangements; accelerating progress in implementing these agreements would stimulate trade. Policymakers could also promote deeper integration with Latin America and the rest of the world by pursuing new trade agreements, leveraging current agreements more effectively, or deepening them to include areas beyond traditional trade issues, and developing port and transport infrastructure.

Financial sector linkages have increased continuously in the Caribbean with cross border capital flows and financial conglomerates dominating the financial system. While the greater interconnectedness can heighten systemic risks and likelihood of contagion, it can have positive impacts provided the regional authorities take steps to prevent the systemic risk. In this context, financial sector reform measures aimed at bolstering and harmonizing prudential regulations in line with international best practices, the strengthening and enhancement of financial sector supervision to include cross border linkages through consolidated supervision, increased cooperation across supervisors in the region, and the establishment of deposit insurance and crisis resolution frameworks will be critical to maintain financial sector stability and minimize the repercussions of any negative shocks.
