Credit Union

A credit union is a member-owned, not-for-profit depository institution. The Federal Credit Union Act defines a federal credit union at 12 USC 1752(1) as "a cooperative association organized in accordance with the provisions of this chapter for the purpose of promoting thrift among its members and creating a source of credit for provident or productive purposes." State-chartered credit unions are organized under comparable state statutes and are supervised by their state regulator, usually alongside the National Credit Union Administration where they carry federal share insurance.

The ownership structure is not a marketing distinction, and it drives the vocabulary. Under 12 USC 1759(a) a member must "subscribe to at least one share of its stock and pay the initial installment thereon," so joining is a purchase of an ownership interest, usually a small par-value share that stays on deposit for as long as you are a member. What a bank would call a savings account is legally a share account, and what a bank would call a checking account is a share draft account: 12 USC 1752(5) defines a member account as "a share, share certificate, or share draft account." For the same reason, a credit union may describe what it pays on savings as a dividend rather than as interest. The asymmetry in the names reflects a real difference in what you hold, not a cosmetic one.

Governance is where the cooperative form is most visible, and the rule is categorical. 12 USC 1760 provides that "irrespective of the number of shares held, no member shall have more than one vote," and that no member may vote by proxy, although a member that is not a natural person may vote through a designated agent. Under 12 USC 1761 the board consists of an odd number of directors, at least five of them, elected annually by and from the members, and 1761(c) provides that no member of the board or of any other committee is compensated as such, with reimbursement of reasonable expenses and certain insurance protection excluded from that. In a shareholder-owned bank, influence scales with shares owned and the board answers to that ownership. Here it does not scale at all, which means a member with a very large balance has no more formal say than one with the minimum.

Membership is a legal condition of the charter rather than a preference. 12 USC 1759(b) limits a federal credit union's field of membership to one of three categories: a single group with a common bond of occupation or association; multiple such groups, subject to size limits; or persons and organizations "within a well-defined local community, neighborhood, or rural district." That is why every credit union has an eligibility page and why the eligible routes are often broader than they first look, since employment, an employer's retirees, family members of existing members, residence, and membership of an associated organization can all qualify depending on the charter. Anyone can find a credit union they are eligible to join; not everyone can join any given one.

The economics follow from two things being absent. There are no outside shareholders with a claim on earnings, and the institution's income is not subject to federal income tax: 12 USC 1768 exempts federal credit unions from all federal, state, and local taxation other than on real and tangible personal property, and 26 USC 501(c)(14)(A) exempts "credit unions without capital stock organized and operated for mutual purposes and without profit." So a dollar of operating surplus at a bank has to pass through corporate tax and can be paid out to shareholders before any of it reaches pricing, while at a credit union the same dollar goes to retained capital or back to members through rates and fees.

That is a structural argument and it should be stated as one. It explains why the pricing reputation exists; it does not establish that any particular credit union is cheaper than any particular bank on any particular product. Efficiency, scale, local competition, and management choices all sit between the structure and the price on the shelf, so the comparison is worth making institution by institution rather than category by category.

The insurance question is the one place a reader can be materially misled, and the answer requires care. Credit union deposits are covered by share insurance under 12 USC 1787(k), administered by the NCUA at the same $250,000 standard amount as bank deposit insurance under 12 USC 1821(a)(1)(E), and the same discretionary five-yearly joint review governs whether either figure moves. The NCUA states that its Share Insurance Fund is backed by the full faith and credit of the United States and covers account holders at all federal credit unions and the overwhelming majority of state-chartered ones.

It does not cover every credit union. The NCUA's own consumer page states that "there are several state-chartered credit unions that are insured by private insurers," and that "these private insurers provide non-federal share insurance coverage of deposits that are not backed by the full faith and credit of the United States." The agency's recommended check is its own Credit Union Locator, which shows whether an institution is federally insured. So "credit unions have an equivalent federal guarantee" is true of almost all of them and not of all of them, and the difference is not something a branch's signage will resolve for you.

One further difference is temporary and dated. The NCUA's rules for how share insurance applies to trust accounts are being brought into line with the FDIC's, by an amendment effective 1 December 2026, so until then the two agencies compute trust coverage differently. A household that has arranged accounts around the FDIC's consolidated trust rule should confirm how the calculation currently works at a credit union rather than assume the answer carries across.

The honest trade-offs are about scale rather than about form. Credit unions range from a single-branch institution serving one employer to nationwide operations with tens of billions in assets, so any claim about branch networks, technology, or product breadth is a claim about a specific institution. Where an institution is small, a narrower product range and a smaller technology budget are real constraints, and the usual answer to the branch and ATM question is cooperative rather than internal: shared-branch and surcharge-free ATM networks let members of participating credit unions transact at other institutions' locations, which is a benefit of the cooperative structure and also something to confirm before assuming it applies.

You confirm you fall inside the field of membership, open a share account, and fund the minimum share that constitutes your ownership stake. From there the accounts behave like their bank equivalents: a share draft account pays third parties, a share account holds savings, and both are covered by share insurance at a federally insured institution. Loan applications are underwritten in the ordinary way; being an owner does not entitle a member to credit.

A hypothetical example of what the governance rule actually means. Ana and Bo belong to the same credit union. Ana holds $400 in total, of which the minimum $25 par-value share is her ownership stake. Bo holds $180,000, which is 450 times Ana's balance ($180,000 ÷ $400). At the annual meeting each of them casts exactly one vote, because 12 USC 1760 provides that no member has more than one vote irrespective of the number of shares held, and neither can vote by proxy. In a shareholder-owned institution, influence tracks the size of the holding, so a 450-fold difference in ownership would ordinarily mean a 450-fold difference in votes.

The one figure worth checking before any of this matters is not on the account agreement. Whether the institution is federally insured is confirmed through the NCUA's Credit Union Locator, and a state-chartered credit union carrying private share insurance instead has coverage that the NCUA says is not backed by the full faith and credit of the United States.

Pros

• Members are owners, so there is no outside shareholder with a competing claim on the institution's earnings.
• Governance is one member, one vote, regardless of balance, and the board is elected by the membership.
• No federal income tax on the institution's income, which leaves operating surplus available for retained capital or member pricing.
• Federally insured credit unions carry the same $250,000 standard amount as insured banks, under a parallel statute and the same review schedule.
• Shared-branch and surcharge-free ATM networks let members of participating institutions transact well beyond their own branches.

Cons

• Membership is restricted by charter, so you have to qualify before you can open anything.
• The federal guarantee is not universal: several state-chartered credit unions carry private share insurance with no federal backing, and confirming which is on you.
• The NCUA's trust-account coverage rules are not yet aligned with the FDIC's, so account titling arranged around bank rules may not produce the same result until the amendment takes effect on 1 December 2026.
• Institution size varies enormously, and at a small one a narrower product range and a smaller technology budget are genuine constraints.
• Being an owner confers a vote, not preferential lending, and not a claim on any particular rate.
• The vocabulary differs from a bank's in ways that make direct comparison harder than it needs to be.
