Every CD you own has a day when it stops being a decision you made and becomes a decision the bank makes for you.
That day is maturity. If you did the sensible thing this year and kept your money in six and twelve month CDs, one of them is coming due soon. What happens next is mostly automatic, and the automatic outcome is bad for you.
Most CDs carry an automatic renewal feature. The OCC’s consumer site describes the consequence in one flat sentence: if your CD had that feature, the bank “may roll the funds into a new CD when the grace period expires,” and “the interest rate on the new CD would be at the current rate offered.” Current rate offered by that bank. Not the rate you shopped a year ago, and not the best rate in the country.
Now the part that decides whether you see it coming.
Truth in Savings, better known as Regulation DD, splits the notice rule in two. For an automatically renewable CD longer than one year, section 1030.5(b)(1) makes the bank mail or deliver a notice at least 30 calendar days before maturity, carrying the full account disclosures for the new term. Thirty days is genuine warning.
For a CD of one year or less, section 1030.5(b)(2) hands the bank a shortcut. It can send that same 30 day notice, or it can simply disclose “before maturity” the maturity dates, the new rate if it knows it, and any change in terms. No minimum number of days is attached to that option. Before maturity. That is the entire timing requirement.
Guess which term most people actually buy.
Here is what the shortcut costs. The FDIC’s deposit-weighted national average for a 12 month CD was 1.71 percent as of August 17. The most competitive CDs on the market reach 4.50 percent APY, per Curinos data published September 1. On $25,000 that spread is roughly $700 over a year, for a deposit carrying the identical federal insurance.
Your bank is not going to renew you at 4.50 percent. It is going to renew you at its own number, and it is betting the notice arrives late, goes unopened, or lands in the middle of a grace period you didn’t know you were in.
The grace period belongs to the bank too. Federal law does not hand you one. The OCC says you “may have a grace period” and that it is “established by the bank.” Seven days is common. Ten happens. Nothing is possible.
So do this before the envelope shows up.
Log into every CD you hold and write down the maturity date. Not the month. The date.
Set two alerts, one at 45 days out and one on maturity day itself. Forty-five days gives you time to open the account the money is moving to, because an interbank transfer takes days and the yield you lose sitting in limbo is real money.
Then tell the bank in writing not to renew, and ask exactly where the funds go on maturity day. A secure message you can screenshot counts. “We’ll take care of it” does not.
Check what the top accounts pay on our best savings accounts page and run the balance through the savings calculator before you pick the destination. On term length, the curve is flat enough that a five year lock is buying you almost nothing right now.
The renewal is the bank’s default. Maturity day is yours. Put it on the calendar.
