What share insurance is
Share insurance protects money you keep at a federally insured credit union. The National Credit Union Administration, or NCUA, is an independent federal agency. Congress created it in 1970. It runs the National Credit Union Share Insurance Fund, known as the NCUSIF.
The fund covers all federal credit unions. It also covers the vast majority of state-chartered credit unions. In most states, state law requires state-chartered credit unions to carry this federal insurance. The NCUSIF is backed by the full faith and credit of the United States government.
Credit unions call deposits "shares" because members are part owners. The insurance works the same way for the member, though. If the credit union fails, the fund covers your balance.

The $250,000 limit, explained
Coverage is up to $250,000 per share owner, per insured credit union, per ownership category. Each part of that phrase matters. Change one, and the math changes.
"Per share owner" means coverage follows the person. "Per insured credit union" means each institution is counted separately. "Per ownership category" means the way an account is titled can create separate coverage buckets.
Covered funds include principal and posted dividends through the date of failure. A member with $40,000 in one account has the whole amount insured. A member with $300,000 in a single category at one credit union has $50,000 above the limit.
- Who owns the account
- Which credit union holds it
- How the account is titled
The sources used here do not spell out the individual ownership categories or how each is calculated. The NCUA's rules and its published guidance cover those details, so check them before assuming an account has its own bucket.
What happens if a credit union fails
If a federally insured credit union fails, the NCUSIF covers each member's account balance dollar-for-dollar up to the limit. Insured funds have historically been available to members within a few days after an insured credit union closes.
The fund is built to make that possible. It keeps its reserve at or near 1.30 percent of federally insured deposits. By law, federally insured credit unions maintain one percent of their deposits in the fund. The NCUA Board can levy a premium if necessary.
Prevention is part of the system too. Only credit unions with sound operational standards qualify for coverage. The NCUA regularly reviews federal credit unions. It works with state regulators on federally insured state-chartered ones.
How it compares with FDIC coverage
The FDIC is also an independent agency created by Congress. Its stated purpose is to maintain stability and public confidence in the nation's financial system. It insures deposits at banks, while the NCUA insures them at credit unions.
This article does not compare dollar limits, categories, or fund details between the two. The FDIC material reviewed here did not include coverage figures, so those rules are unconfirmed. Readers who want a side-by-side should read the FDIC's own deposit insurance guidance next to the NCUA's.
One practical point holds either way. Coverage is counted per institution. Money at a credit union and money at a bank sit with different insurers, and each is measured on its own terms.
Checking your own accounts
Start by confirming the credit union is federally insured by the NCUSIF. Do that before you deposit money. The NCUA's consumer pages are the place to verify it.
Then add up your balances at that one institution. Group them by ownership category. If any group passes $250,000, the excess is not covered under the limit described here.
The NCUA says its rules and the Federal Credit Union Act control how accounts are insured. It also says no one may imply a credit union offers coverage that differs from that formal structure. Treat any claim of extra protection with caution.
Review your accounts periodically. Do it again whenever you open or change an account. A new joint account or a retitled balance can shift where your money falls.
- Is this credit union federally insured by the NCUSIF?
- How is each account titled, and what category is it in?
- Do my balances here exceed $250,000 in any category?
