Welcome to Defiance State Bank


By operation of federal law, beginning January 1, 2013, funds deposited in a noninterest-bearing transaction account (including Interest on Lawyer Trust Accounts) no longer will receive unlimited deposit insurance coverage by the Federal Deposit Insurance Corporation (FDIC). 

Beginning January 1, 2013, all of a depositor's accounts at an insured depository institution, including all noninterest-bearing transaction accounts, will be insured by the FDIC up to the standard maximum deposit insurance amount ($250,000), for each deposit insurance ownership category.

For more information about FDIC insurance coverage of noninterest-bearing transaction accounts, visit
