The FDIC released this press release on 7/21/2010 which announced that the standard maximum deposit insurance amount has been permanently increased to $250,000. Here's an excerpt from the press release:
On July 21, 2010, President Barack Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act, which, in part, permanently raises the current standard maximum deposit insurance amount to $250,000. The standard maximum insurance amount of $100,000 had been temporarily raised to $250,000 until December 31, 2013. The FDIC insurance coverage limit applies per depositor, per insured depository institution for each account ownership category.
The temporary increase from $100,000 to $250,000 was effective from October 3, 2008, through December 31, 2010. On May 20, 2009, the temporary increase was extended through December 31, 2013.
One thing that was not mentioned in the press release was the retroactive increase to Jan. 1, 2008. IndyMac depositors and depositors from a few other banks that failed in 2008 before October will now be able to recover some or all of their money that had been uninsured. Checks will be mailed starting on 7/22/2010.
The deposit insurance change affects credit unions as well - here is the press release by the NCUA.
