To mitigate systemic risk, some regulators have advocated the greater use of centralized counterparties (CCPs) to clear Over-The-Counter (OTC) derivatives trades. Regulators should be cognizant that large banks active in the OTC derivatives market do not hold collateral against all the positions in their trading book and the paper proves an estimate of this under-collateralization. Whatever collateral is held by banks is allowed to be rehypothecated (or re-used) to others. Since CCPs would require all positions to have collateral against them, off-loading a significant portion of OTC derivatives transactions to central counterparties (CCPs) would require large increases in posted collateral, possibly requiring large banks to raise more capital. These costs suggest that most large banks will be reluctant to offload their positions to CCPs, and the paper proposes an appropriate capital levy on remaining positions to encourage the transition.

In the aftermath of the recent financial crisis, the federal government has pursued significant regulatory reforms, including proposals to measure and monitor systemic risk. However, there is much debate about how this might be accomplished quantitatively and objectively—or whether this is even possible. A key issue is determining the appropriate trade-offs between risk and reward from a policy and social welfare perspective given the potential negative impact of crises. One of the first books to address the challenges of measuring statistical risk from a system-wide persepective, Quantifying Systemic Risk looks at the means of measuring systemic risk and explores alternative approaches. Among the topics discussed are the challenges of tying regulations to specific quantitative measures, the effects of learning and adaptation on the evolution of the market, and the distinction between the shocks that start a crisis and the mechanisms that enable it to grow.

Recovery and resolution regimes are being developed for central counterparties (CCPs). We analyse current resolution tools in the context of policy, which is to restore the critical functions of a failed CCP. We conclude that the toolkit is insufficient to avoid the costs of resolution being borne by taxpayers, and propose alternative policy suggestions for addressing the problem of a failed CCP.

Financial network analysis is used to provide firm level bottom-up holistic visualizations of interconnections of financial obligations in global OTC derivatives markets. This helps to identify Systemically Important Financial Intermediaries (SIFIs), analyse the nature of contagion propagation, and also monitor and design ways of increasing robustness in the network. Based on 2009 FDIC and individually collected firm level data covering gross notional, gross positive (negative) fair value and the netted derivatives assets and liabilities for 202 financial firms which includes 20 SIFIs, the bilateral flows are empirically calibrated to reflect data-based constraints. This produces a tiered network with a distinct highly clustered central core of 12 SIFIs that account for 78 percent of all bilateral exposures and a large number of financial intermediaries (FIs) on the periphery. The topology of the network results in the “Too- Interconnected-To-Fail” (TITF) phenomenon in that the failure of any member of the central tier will bring down other members with the contagion coming to an abrupt end when the ‘super-spreaders’ have demised. As these SIFIs account for the bulk of capital in the system, ipso facto no bank among the top tier can be allowed to fail, highlighting the untenable implicit socialized guarantees needed for these markets to operate at their current levels. Systemic risk costs of highly connected SIFIs nodes are not priced into their holding of capital or collateral. An eigenvector centrality based ‘super-spreader’ tax has been designed and tested for its capacity to reduce the potential socialized losses from failure of SIFIs.

Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience interested in economic policy issues. This Web-only series replaced Staff Position Notes in January 2011.

Changes to the regulatory system introduced after the financial crisis include not only mandatory clearing of OTC derivatives at central counterparties and margining of uncleared derivatives, but also prudential measures, including notably a “Liquidity Coverage Ratio” which obliges firms to set aside high-quality liquid assets (HQLA) as a stopgap against anticipated cash outflows. We examine factors which may affect the demand for HQLA in a severely stressed market following a hypothetical default of a major clearing member. Immediately following a major default, the amount of HQLA demanded by the whole market would spike. We estimate the size of the spike and draw conclusions as to whether the depth of the market is adequate to absorb it.

"This book is designed to provide the reader with an insight into the main concepts involved in the handling of payments, securities and derivatives and the organisation and functioning of the market infrastructure concerned. Emphasis is placed on the general principles governing the functioning of the relevant systems and processes and the presentation of the underlying economic, business, legal, institutional, organisational and policy issues. The book is aimed at decision-makers, practitioners, lawyers and academics wishing to acquire a deeper understanding of market infrastructure issues. It should also prove useful for students with an interest in monetary and financial issues."--Introduction (Pg. 20, para 8).
