Of particular interest, demand for Italian bonds dropped significantly. This matters because European banks are exposed very heavily to Italian sovereign debt – the top 91 banks own €100bn of the stuff in their trading books. This is quadruple the trading holdings of Spanish debt, and 22 times holdings of Irish debt. Indeed, Italian debt is held in the trading books of Europe’s banks more than any other European sovereign – even German-issued debt totals just $70bn.
Italian banks Intesa and Unicredit carry the greatest trading exposure to Italy, as we would expect. After that come Deutsche Bank and Credit Agricole, each with about €10bn. See the data, split by bank, below:
