Mr. Eugenio M Cerutti and Haonan Zhou
Post-crisis dynamics show a shrinkage in the overall amount of crossborder bank lending, which has been interpreted in the literature as a retreat in financial globalization. In this paper, we argue that aggregate figures are not sufficient to support such a claim in terms of the overall structure of the global banking network. Based on a systematic approach to measuring, mapping and analyzing financial interconnectedness among countries using network theory, we show that, despite the decline in aggregate lending volumes, the structure of the network has developed increased connections in some dimensions. Some parts of the network are currently more interlinked regionally than before the crisis, and less dependent on major global lenders. In this context, at a more disaggregate level, we document the characteristics of the increasing regionalization of lending flows, the different evolution of linkages through bank affiliates and direct cross-border claims, as well as the shift in the importance of key borrower and lender nodes. These changes in the banking network have important insights in terms of policy implications since they indicate that the global banking network has evolved, but it has not undergone a generalized retrenchment in financial linkages.

Abstract

Analysis and Plans, presents an assessment of 1997 survey data and a summary of improvements introduced, as a result of countries' participation in the 1997 Coordinated Portfolio Investment Survey, into national systems for collecting data on international (cross-border) portfolio investment The chapter reviews developments that occurred in international financial markets in the 1980s and 1990s, and the Godeaux Report assessment and recommendations about global data on international portfolio investment flows and stocks. The objectives set for the 1997 survey, the scope of survey results, and the process by which results have been assessed in the chapter. Since publication of the Godeaux Report, substantial expansion and evolution have occurred in exchange and over-the-counter markets for financial derivatives covering a range of financial risks. These markets now have the capacity, in effect, to change the currencies, maturities, and marketability of the financial instruments underlying associated derivative contracts. It is recommended that vigorous efforts should be made to secure the participation of more major investing countries in order to address the under-reporting of global portfolio investment assets and to confirm the reliability of the global data on portfolio investment liabilities.
