Ally Bank was paying competitive interest rates on savings and CDs - nothing in the stratosphere for online banks, but competitive nonetheless. Regulators recently proposed rules that restrict troubled banks from paying excessively high rates on deposit accounts as a tactic to gain deposits. Apparently the FDIC and the American Bankers Association (ABA) think Ally Bank may be doing just that.
The ABA wrote a letter to the FDIC asking for more scrutiny of Ally Bank, and it appears that the FDIC is starting to apply pressure.
I don't know the details of Ally Bank's strength, nor of their battle with the ABA, so I don't know if the action is fair or not. I suspect we won't know everything until long after the fighting ends.
