Efficient and stable payments systems are of fundamental importance in maintaining an orderly international monetary system. Major disruptions of national and international payments systems would have highly adverse effects on international trade, capital flows, and real activity. A key issue--now being addressed by authorities in a number of major countries--is whether existing institutional arrangements need to be modified in order to reduce the liquidity and credit risks that have arisen as a result of the expansion of international capital flows and the growing integration of major financial markets. This paper examines the nature of these risks and the policies that are being implemented to manage or curb them.
We study liquidity and systemic risk in high-value payment systems. Flows in high-value systems are characterized by high velocity, meaning that the total amount paid and received is high relative to the stock of reserves. In such systems, banks rely heavily on incoming funds to finance outgoing payments, necessitating a high degree of coordination and synchronization. We use lattice-theoretic methods to solve for the unique fixed point of an equilibrium mapping and conduct comparative statics analyses on changes to the environment. We find that banks attempting to conserve liquidity cause an increase in the demand for intraday credit and, ultimately, a disruption of payments. Additionally, we find that when a bank is identified as vulnerable to failure and other banks choose to cancel payments to that bank, there are systemic repercussions for the whole financial system. -- Systemic risk ; financial networks ; high-value payment systems ; precautionary demand
Drawing on wide-ranging contributions from prominent international experts and discussing some of the most pressing issues facing policy makers and practitioners in the field of payment systems today, this volume provides cutting-edge perspectives on the current issues surrounding payment systems and their future.It covers a range of continually im
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.
This book describes various approaches in modelling financial risks and compiling ratings. Focusing on emerging markets, it illustrates how risk assessment is performed and analyses the use of machine learning methods for financial risk assessment and measurement. It not only offers readers insights into the differences between emerging and developed markets, but also helps them understand the development of risk management approaches for banks. Highlighting current problems connected with the evaluation and modelling of financial risks in the banking sector of emerging markets, the book presents the methodologies applied to credit and market financial risks and integrated and payment risks, and discusses the outcomes. In addition it explores the systemic risks and innovations in banking and risk management by analyzing the features of risk measurement in emerging countries. Lastly, it demonstrates the aggregation of approaches to financial risk for emerging financial markets, comparing the experiences of various countries, including Russia, Belarus, China and Brazil.
"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).
This book provides an authoritative overview of the complex practical and policy implications of international payments systems by central bankers from both developed and developing countries, Payments Systems in Global Perspective presents the results of a survey of international central bank practice conducted by the Bank of England.
Banks and financial market infrastructures (FMIs) that are not able to fulfill their payment obligations can be a source of financial instability. This paper develops a composite risk indicator to evaluate the criticality of participants in a large value payment system network, combining liquidity risk and interconnections in one approach, and applying this to the TARGET2 payment system. Findings suggest that the most critical participants in TARGET2 are other payment systems, because of the size of underlying payment flows. Some banks may be critical, but this is mainly due to their interconnectedness with other TARGET2 participants. Central counterparties and central securities depositories are less critical. These findings can be used in financial stability analysis, and feed into central bank policies on payment system access, oversight, and crisis management.
