The European Central Bank lent commercial banks 75 billion euros ($104 billion) in three-month funds Wednesday, 25 billion euros more than in a previous operation last month, the bank said on its Web site.

The average interest rate paid was 4.5%, slightly lower than in a previous auction for three-month deposits last month, but the amount allotted shows that commercial banks are still worried that the U.S. subprime crisis could affect money markets.
