The FDIC report showed that in the third quarter of 2009, the US banking industry posted a net profit of $2.8 billion. However, loan balances declined by the largest percentage since 1984 and 50 banks collapsed, the highest number since 1992. While only large banks were profitable, revenues increased and securities losses decreased, partly offsetting higher loan loss provisions. Troubled loans continued rising but at a slower pace, and net interest margins rose to a four-year high. However, over a quarter of banks remained unprofitable and the FDIC fund insuring deposits fell into the red for the first time since 1992.
