As of 5:15pm CDT, two small banks have failed: First National Bank, Rosedale, Mississippi and Arcola Homestead Savings Bank, Arcola, Illinois. The FDIC wasn't able to find a buyer for Arcola Homestead Savings. Thus, the FDIC will be mailing checks to depositors.
Please refer to the FDIC press release page
for more details. I'll have more info on these in my bank failure review post later today.
