Regulation DD implements the Truth in Savings Act through standardized U.S. consumer deposit disclosures for rates, APY, fees, terms, and advertising.
Regulation DD is the Consumer Financial Protection Bureau rule at 12 CFR Part 1030 that implements the Truth in Savings Act. It requires covered depository institutions to give consumers standardized information about deposit-account rates, annual percentage yield (APY), fees, balance rules, and other terms so accounts can be compared more meaningfully.
Regulation DD is not another name for the statute. The Truth in Savings Act is the law; Regulation DD is the implementing rule.
Regulation DD applies to accounts held by, or offered to, consumers for personal, family, or household purposes. It generally covers checking, savings, money market deposit, and time-deposit accounts when the rule’s definitions are met.
Important boundaries include:
Section 1030.4 requires account disclosures before a consumer opens an account or receives a covered service, subject to specific delivery rules. Disclosures must address applicable terms such as:
| Area | Examples of required information |
|---|---|
| Rate | Interest rate, APY, fixed-rate period, or variable-rate mechanics |
| Compounding | How often interest compounds and is credited |
| Balance | Minimum balances and the method used to calculate interest |
| Fees | Amount or calculation method and conditions for covered account fees |
| Transactions | Applicable limits on deposits or withdrawals |
| Time accounts | Maturity, early-withdrawal penalties, renewal, and grace-period terms |
| Bonuses | Amount or type and the balance or time conditions needed to earn it |
Not every item applies to every account. The purpose is to disclose the terms that actually control the offered product.
Under Regulation DD, the interest rate is an annual rate that does not reflect compounding. APY is an annualized percentage yield calculated under Appendix A using the interest rate and compounding assumptions.
This distinction helps consumers compare deposit earnings, but APY is not an after-tax return and does not eliminate the need to review fees, balance tiers, introductory periods, and withdrawal restrictions.
Assume two hypothetical accounts show these disclosures:
| Term | Account A | Account B |
|---|---|---|
| APY | 4.05% | 4.20% |
| Monthly maintenance fee | USD 0 | USD 10 unless a USD 5,000 daily balance is maintained |
| Balance used for interest | Daily balance | Daily balance |
| Rate behavior | Variable | Variable |
The higher APY does not prove Account B will produce the higher net result. A consumer expecting to keep USD 2,000 would compare expected interest with USD 120 of potential annual maintenance fees, while also checking whether either APY can change. The disclosure makes these inputs visible; it does not choose the account for the consumer.
If an institution sends a periodic statement, section 1030.6 requires applicable information such as the APY earned during the statement period, dollar interest earned, covered fees debited, and the statement period dates. The rule does not itself require an institution to provide periodic statements for every account.
For a disclosed term that may reduce APY or adversely affect the consumer, section 1030.5 generally requires notice at least 30 calendar days before the effective date. Exceptions include certain variable-rate changes, check-printing fees, and short-term time accounts. Automatically renewing time accounts have separate maturity-notice provisions.
Deposit advertising must not be misleading or inaccurate. When an advertisement states a rate of return, Regulation DD generally requires use of the term “annual percentage yield” and can trigger additional disclosures. Advertisements mentioning bonuses, minimum deposits, time accounts, or overdraft services can have specific requirements.
Covered institutions must retain evidence of compliance for at least two years after the relevant disclosure or action was required. The record need not always be a paper copy, but the institution must be able to demonstrate or reconstruct its compliance.
