Regulation DD, 12 CFR pts. 230 and 1030 (full-text)..
Regulation DD requires disclosures about fees, annual percentage yield (APY), interest rate, and other terms. Under Regulation DD, a depository institution may not advertise deposit accounts in a way that is misleading or inaccurate or misrepresents the depository institution's deposit contract.
If an electronic advertisement displays a triggering term, such as "bonus" or "APY," then Regulation DD requires the advertisement to clearly state certain information, such as the minimum balance required to obtain the advertised APY or bonus. For example, an electronic advertisement can provide the required information via a link that directly takes the consumer to the additional information.
