Abstract

This study improves upon global flow of funds (GFF) statistics to measure global financial stability at the national and cross-border sectoral levels. After investigating the data sources and rebuilding the statistical framework to establish the GFF statistical matrix of G20 countries, we evaluate their financial risks and influences. We then connect the GFF matrix with the sectoral account data and the flow of funds to establish the sectoral from-whom-to-whom financial stock matrix (FFSM). The FFSM focuses on counterparty national and cross-border exposures of the sectors in China, Japan, and the United States to construct country-specific financial networks and connect each country-level network based on cross-border exposures. The analytical results systematically show the financial relationships among G20 countries in the GFF, the characteristics of overseas investment among China, Japan, and the United States, and external shocks and internal influences.

Notes

  1. They are (1) build-up of risk in the financial sector, (2) cross-border financial linkages, (3) vulnerability of domestic economies to shocks, and (4) improving communication of official statistics.

  2. For the first version of the GFFM, see Zhang and Zhao’s paper (2019, 535–536).

  3. For the calculation method of Table Y refer to Zhang (2020), 108–110.

  4. The ROW sector in the FA is designed from a foreign standpoint, so the assets and liabilities of the ROW sector show an opposite relationship when observed from the domestic standpoint, and the assets of the ROW sector are the liabilities of the domestic.

  5. To avoid double counting, the claims, that is, loans and deposits, of JP to CN in Table A6.2-S banks' cross-border positions on residents of JP in the LBS account are subtracted from the claims of FC by ROW in FFSM (see Table 3).

  6. CPIS: Table 10, Reported Portfolio Investment Assets by Sector of Holder, and Sector and Economy of Nonresident Issuer for Specified Economies, December 2018.
