A saver who spread money across a Capital One account and a Discover account to keep each balance under the FDIC’s $250,000 line may no longer have two limits. Capital One’s own savings disclosure says that “any Capital One or Discover Bank deposit accounts opened on or after May 18, 2025 are immediately counted with your other Capital One deposit accounts for determining deposit insurance coverage by the FDIC.” That single sentence, on the product page for Capital One 360 Performance Savings, is the controlling record for this claim.
The disclosure sentence and what it covers
The wording sits in the deposit-insurance disclosure on the 360 Performance Savings page, which showed rates effective as of 9/29/2026 when it was re-read on the eve of this article’s publication. It is Capital One’s statement of how it counts deposits for FDIC purposes, not an FDIC ruling,. The rule turns on an account’s opening date: any account, at either brand, opened on or after May 18, 2025 is “immediately counted” together with the saver’s other Capital One deposit accounts.
May 18, 2025 is the day the merger closed. Capital One’s completion announcement carries that date, and founder and chief executive Richard D. Fairbank said in it that the deal “brings together two innovative, mission-driven companies that together are poised to deliver breakthrough products and experiences to consumers, businesses, and merchants.” The release reported $367.5 billion in Capital One deposits as of March 31, 2025, and it does not mention the FDIC, so it does not settle the insurance question on its own.
How the $250,000 limit works
The FDIC states the standard rule in one line on its deposit insurance page: coverage is “$250,000 per depositor, per FDIC-insured bank, for each account ownership category.” Two words carry the weight here. “Bank” means a legally separate insured institution, and that is the reason holding money at a Capital One and a Discover account once doubled the protection. “Category” means single accounts, joint accounts and the other recognized ownership types, and the FDIC notes that using different categories at one bank creates separate $250,000 protections.
The disclosure changes the first word, not the second. Once accounts at the two brands are counted together, the balances add up inside each ownership category. Single-owner balances at the two brands that once each sat under $250,000 now add together, and any combined total above $250,000 in that category is above the standard limit. Deposits in different categories, such as a joint account, are counted separately from that single-owner total.
The later date on both banks’ own pages
The May 18, 2025 date is not the only one in the banks’ own materials. Capital One’s Discover FAQ says “On May 18, 2025, Discover merged into Capital One,” and then states: “Starting November 18, 2025, if you have both Capital One and Discover deposit accounts, they’ll be jointly insured by the Federal Deposit Insurance Corporation (FDIC) up to the allowable limits.” Discover’s FDIC coverage page repeats that sentence word for word.
Read together, the pages describe two tracks. Accounts opened on or after May 18, 2025 were combined immediately, per the savings disclosure. Accounts opened before that date kept separate coverage for a transition period, and by both banks’ wording the combined treatment applies to deposit accounts from November 18, 2025 onward. That date is now past, so a saver reading the FAQ in late September 2026 would find that both brands’ balances are expected to count toward a single limit for a given ownership category. The article’s headline claim, about accounts opened since May 2025, is the narrower and earlier-effective piece of that picture; it should not be read as saying that older Discover accounts were never affected.
Certificates of deposit and the staggered end dates
Both FAQ pages add an exception for certificates of deposit, and it is written in terms of maturity dates. A CD that matures after Nov. 18, 2025 “will remain separately insured by the FDIC until their maturity date after Nov. 18, 2025.” A CD that matured before that date and was renewed for a different term or dollar amount “will remain separately insured only until Nov. 18, 2025.” One renewed for the same term and amount stays separate “until the first maturity date after Nov. 18, 2025.”
The date to check on a specific certificate is its own maturity or renewal date, which appears on the account’s disclosure and statements. The consequence is practical for retirees who ladder CDs at more than one bank and count each rung as separately protected.
What the pages do not say
Neither bank’s page gives a dollar figure for how many savers are near the limit, and neither says that an over-limit balance is at immediate risk. FDIC coverage matters only if the insured institution fails. The FDIC’s deposit insurance page is the free official source for the standard amount and for the ownership categories. Capital One’s disclosure page and Discover’s coverage page are the two bank records that determine how the two brands’ accounts are being counted.
The controlling record for the title remains one sentence on Capital One’s own 360 Performance Savings page, dated by its 9/29/2026 rate line: accounts at either brand opened on or after May 18, 2025 are counted with the saver’s other Capital One deposit accounts.
Keeping a plan ready for a locked bank account
Savers who hold most of their cash at one bank are the readers most exposed when a creditor freezes an account. The kit is for people who want a set order of steps for that situation before it happens.
The Bank Account & Debt Protection Kit includes the frozen-account response and the debt-validation steps, which lay out a task order for answering a freeze or a collector’s letter.
