It requires disclosure, not a price. The Act and Regulation DD tell an institution what it must tell you and when, and how to calculate and label the yield. They do not cap fees or set interest rates. An overdraft or minimum balance fee can be any amount, so long as it is disclosed as the rule requires.
The disclosure map.
- At account opening and on request (1030.4). Before the account is opened or a service is provided, the institution must give the account terms, including the rate and annual percentage yield, fees, minimum balances, transaction limits and, for time accounts, maturity and early-withdrawal penalties. A customer who is not present and does not open the account online may instead get them by mail within 10 business days. The institution must also give the terms to anyone who asks.
- Before an adverse change (1030.5(a)). A change that may reduce the yield or otherwise adversely affect you needs notice mailed or delivered at least 30 calendar days before it takes effect. Rate changes on variable-rate accounts, check printing fees and time accounts of one month or less are excepted.
- Before a renewing CD matures (1030.5(b)). For a time account longer than one month that renews automatically, notice must go out at least 30 calendar days before maturity, or at least 20 calendar days before a grace period of at least five days ends.
- On periodic statements (1030.6). If the institution sends one, it must show the "annual percentage yield earned," the interest earned, the fees charged, the length of the period and, where required, total overdraft and returned-item fees for the period and the year to date.
- In how interest is paid (1030.7). Interest must be calculated on the full principal each day, by the daily balance or average daily balance method, with a daily rate of at least 1/365 of the interest rate. The rule does not require any particular compounding frequency.
- In advertising (1030.8). An ad may not be misleading, may not call an account "free" or "no cost" if a maintenance or activity fee may be imposed, and must state any rate of return as an "annual percentage yield."
Who it covers. Regulation DD "applies to depository institutions except for credit unions," though its advertising rules reach anyone who advertises a depository institution's account, including deposit brokers. For credit unions, 12 U.S.C. 4311(b) requires the National Credit Union Administration to issue a substantially similar rule, which it has done at 12 CFR part 707.
Enforcement. The Act is enforced administratively by the federal banking agencies, the NCUA and the CFPB under 12 U.S.C. 4309. The section that let account holders sue an institution for violations, 12 U.S.C. 4310, was repealed by a 1996 law, with the repeal taking effect five years later. A depositor's route under the Act today is a complaint to the institution's regulator.
