Per a note on statement, Southern Bank (Missouri, Arkansas, Illinois) has renamed their Kasasa Cash account to Southern Cash. Quote:
"Your Kasasa Cash account has been renamed to Southern Cash. Don't worry, nothing else has changed. You'll continue to enjoy all the current features of the account."
The Southern Bank website does not display any info on the old Kasasa Cash or the new Southern Cash accounts. And therefore there are no interest rates listed for these, which means they can easily change the interest rate behind your back.
There is a new account called Southern Advantage, paying 2.01% up to $25k if 20 transactions. https://bankwithsouthern.com/checking-and-savings/southern-advantage/
Account available to residents of Missouri, Arkansas, and Illinois only.
