Top European banks face risk of financial trouble, warns ECB.

The European Central Bank (ECB) has warned that the eurozone's top banks could be hit if their financial clients, such as funds, insurers and clearing houses, withdrew their deposits or otherwise ran into trouble. The biggest risk identified was that shadow banks withdrew their funds from banks, such as deposits and repurchase agreements. These account for 13% of all traditional banks' liabilities -- or more for larger banks.
