My bank had a promotional 7 month CD offering a few months ago and this product was set as single maturity. Mgmt now wants to make the CDs automatically renewable. Can this be a subsequent change under TISA with a 30-day notification? I would think single maturity vs. auto renewable is a preference and couldn't necessarily be considered "to the customer's benefit". Any suggestions?!?

Sounds like the old asset-liability committee is getting a little greedy. The 7 month CD probably carried a high rate of interest and if it will renew into a significantly lower interest rate, you will have some dissatisfied customers on your hands looking for the address of your regulator. Each customer should be given a notice prior to renewal of the change.
