The $250,000 Promise
When a bank fails, insured depositors don't lose their money. That's not a marketing claim, it's federal law, and it has specific limits worth knowing exactly.
Who is actually promising what
Deposit insurance is a federal guarantee, not a bank's marketing. If an insured bank fails, the FDIC makes insured depositors whole — historically within a few business days, and no insured depositor has lost insured funds since the FDIC began operating in 1934.
Credit unions have their own version: the NCUA insures share accounts at federally insured credit unions at the same $250,000 level. Different agency, same promise.
The limit is stated in a specific and easily misread way: $250,000 per depositor, per insured institution, per ownership category. Three separate 'per's, and every one of them changes the answer.
The word that trips everyone up: 'category'
Most people read the limit as 'per account'. It isn't. An ownership category is how an account is titled — single, joint, certain trusts, certain retirement accounts.
Every account you hold in the SAME category at the SAME bank is added together first, and then the $250,000 cap is applied to the total. Opening a second account at the same bank in the same category adds no coverage at all.
What does add coverage: a second bank, or a genuinely different ownership category. A joint account, for instance, is its own category, and each co-owner is insured up to $250,000 for their share.
Combine first, then cap. Not cap each account, then add.
It covers failure, not loss
This is the distinction the whole lesson turns on. Deposit insurance protects you against the institution going under. It does not protect you against an investment going down.
Stocks, bonds, mutual funds, ETFs, crypto, and life insurance are never FDIC-insured — not even when you buy them through your bank, at a branch, from someone wearing the bank's badge. The building doesn't determine the coverage; the product does.
Nothing insures you against market losses. That isn't a gap in the system — a guaranteed investment return would be a contradiction in terms.
FDIC (banks) and NCUA (credit unions) each insure $250,000 per depositor, per institution, per ownership category. Investments are never covered.
