LOS ANGELES, Oct 30 (Reuters) - U.S. authorities seized nine failed banks on Friday, the most in a single day since the financial crisis began and the latest stark sign that substantial parts of the nation's banking industry are being crippled by bad loans.

The move brought the total number of failed banks in 2009 to 115 -- their highest annual level since 1992 -- with analysts expecting more to come. Among the lenders seized Friday was Los Angeles-based California National Bank, in what was the fourth-largest U.S. bank failure this year.

The largest institution to fail in the current financial crisis was Washington Mutual, which boasted $307 billion in assets when it was shuttered in September 2008.

U.S. Bancorp (USB.N: Quote, Profile, Research) on Friday acquired the nine banks that had been held by FBOP Corp, picking up $18.4 billion in assets and $15.4 billion of deposits.

Visibly worried employees lined up to file into Cal National's head offices in the heart of a deserted downtown Los Angeles on a chilly Friday evening, where they had their employers' fate explained to them, regulators said.
