In March 2023, Silicon Valley Bank depositors woke up to a bank that no longer existed. By Monday, the FDIC had moved every account to a bridge bank, and within weeks First-Citizens Bank & Trust took over the deposits. The depositors got their money. Their interest rates were another story. That weekend is the honest preview of what happens to a CD ladder when a bank fails: your principal and accrued interest survive up to $250,000 per depositor per bank. Your locked-in rate can be gone by Monday morning. Federal rules hand you one consolation: if the new bank lowers your rate, you can pull the whole balance out with no early withdrawal penalty.
The two ways a bank failure gets resolved
The FDIC's favorite move is called a Purchase and Assumption transaction. A healthy bank takes over the failed bank's insured deposits, and you typically become a customer of the new bank overnight. This usually happens over a weekend. You wake up Monday, your CDs are there, and you can access them. Silicon Valley Bank's 2023 collapse followed this script: the FDIC first moved deposits to Silicon Valley Bridge Bank, then First-Citizens Bank & Trust agreed to take over the deposits and loans.
When no acquirer steps in, the FDIC pays you directly out of the Deposit Insurance Fund. Payment usually starts within a few business days. You get a check or direct deposit for your full principal plus accrued interest, capped at the $250,000 limit. Either way, insured money moves fast. It is the uninsured portion where things get slow and uncertain.
What the $250,000 limit means for your rungs
What ladder owners usually miss is that every rung at the same bank counts toward a single $250,000 limit. A $200,000 ladder spread across five CDs at one bank is fully covered. A $300,000 ladder at one bank leaves $50,000 exposed. That excess becomes an unsecured claim against whatever assets remain. You receive a Receiver's Certificate and wait through the liquidation process, which can stretch for months or longer and often returns only a fraction of the excess.
This is one more reason to spread large ladders across institutions. The limit applies per bank, so a ladder split across three banks can be covered up to $250,000 at each. Ownership categories multiply coverage too: a joint account owned by two people is insured up to $250,000 per co-owner, so a couple can protect $500,000 in one joint CD, and that coverage sits separate from each person's individual accounts at the same bank. One trap worth knowing: if a co-owner dies, the surviving owner's share gets reclassified as single ownership after a six-month grace period, so coverage can shrink without you moving a dollar.
The rate reset nobody warns you about
The FDIC protects your money. It does not protect your rate. When an acquiring bank takes over, the original deposit contract ceases to exist. The new bank may create a new contract with a different interest rate, which means the 5-year rung you locked at a great rate can come back at whatever the new bank is posting. Your CD agreement is not binding on the new institution in a failure scenario.
The new bank must notify you of account changes like CD rate adjustments in writing. Once you receive that notice, you can withdraw your full insured balance without paying an early withdrawal penalty, even if the rung has years left. Read the notice, compare the new rate to the market, and if the number is worse, take the money and rebuild the rung elsewhere. No penalty, no waiting for maturity.
Frequently asked questions
Does FDIC insurance protect every rung of a CD ladder?
Yes, as long as the combined balance plus accrued interest stays under $250,000 per depositor, per bank, per ownership category. Every rung counts toward that one limit at that bank, so a $200,000 ladder at a single bank is fully covered but a $300,000 one is not.
Can the new bank change my CD interest rate after a failure?
Yes. When an acquiring bank takes over a failed bank's deposits, the original deposit contract ends. The new bank may set a different rate on your CD. If the new rate is lower, you can withdraw your full insured balance without an early withdrawal penalty.
What happens if no bank buys the failed bank?
The FDIC pays you directly from the Deposit Insurance Fund, usually within a few business days. You receive your full principal plus accrued interest up to the $250,000 limit, by check or direct deposit.
What happens to money above the $250,000 limit?
Anything over the limit becomes an unsecured claim against the failed bank's remaining assets. You get a Receiver's Certificate and wait through the liquidation process, which can take months or longer and often returns only a fraction of the excess.
Does spreading a CD ladder across banks increase FDIC coverage?
Yes. The $250,000 limit applies per institution, so a ladder split across three banks can be covered up to $250,000 at each. Joint accounts and trust accounts are separate ownership categories with their own limits at the same bank.
