Analysts are poring over new statistics on debt exposure from the Bank for International Settlements released today. As has become customary with each quarterly release of this data, the report’s (virtual) pages are flipped directly to the section detailing the size of banks’ portfolio of bonds issued by governments on the euro area’s troubled periphery.

French and German banks are the most exposed, by far, to troubled government debt. Although banks have been reducing their exposure—the value of debt from Greece, Ireland, Portugal and Spain held by foreign banks fell by 35% last year—significant holdings remain. German banks, for example, were sitting on more than 40% of the US$54bn in foreign-held Greek government debt at the end of 2010.

The inevitable restructuring of Greek debt will be painful for lenders, although the severity will vary according to the method employed. In the meantime, attempts to cajole banks into a voluntary refinancing of Greece’s daunting debt pile (along the lines of the “Vienna Initiative” in central and eastern Europe) will continue, despite a glaring lack of incentives for lenders to take part.
