IMF Working Papers, April 1, 2011

Source details

Study period: 1978-2009.
Coverage: cross-border bank lending data for 184 countries.
Analytical focus: network metrics of centrality, connectivity, and clustering.
Publication: IMF Working Paper No. 2011/074, Issue 074, Volume 2011, Pages: 41, ISBN: 9781455227051, ISSN: 1018-5941.

The global banking network is documented as relatively unstable over 1978-2009.
Structural breaks in network indicators identify several waves of capital flows.
Interconnectedness rankings are relatively volatile over the period, with borrower rankings especially volatile.
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.

Centrality: used to assess relative importance of nodes in the cross-border banking network.
Connectivity: tracked over time and shown to decline around crises.
Clustering: examined to characterize local concentration and grouping within the network.
