Answer:
It isn't a violation of FDIC requirements because the amount isn't correct, but if it isn't the official sign it is a violation for that reason. The official sign is 7" by 3" in size, with black lettering and gold background. Use of the temporary sign ($250,000) is optional. If the temporary FDIC sign is not used, institutions are encouraged to post the following statement, or affix a sticker with this statement, next to the official FDIC sign (teller station sign): "FDIC deposit insurance temporarily increased from $100,000 to $250,000 per depositor through December 31, 2013."
