External Linkages and Contagion Risk in Irish Banks
February 1, 2007
The large and growing international linkages of big Irish banks expose them to idiosyncratic shocks arising in other countries. We analyze international interdependencies of Irish banks-during both normal times and in periods of large shocks or extreme events-using an existing methodology with distance to default (DD) data constructed from the banks' equity prices. The data covers daily observations from January 1994 to November 2005. We first construct rolling correlations between DDs of Irish banks and those of banks from other European countries and the U.S. to analyze trends in cross-country interdependencies. We then use a multinomial logit model to estimate the number of banks in Ireland that experience a large shock on the same day as banks in other countries ("coexceedances"), controlling for Ireland-specific and global factors. We find evidence of increasing cross-border interdependencies over time; differing interlinkage patterns in the pre-Euro, post-Euro, and the post-September 11th periods; and significant cross-border contagion risk from the United Kingdom, the United States, and the Netherlands.
