Credit Unions (United States) — NAICS 52213

An investor's primer. NAICS (North American Industry Classification System) 2022 code 52213 — a five-digit NAICS industry. This is a short "rollup" page: NAICS 52213 contains exactly one detailed industry, 522130, so the two are effectively the same thing. For full detail, read the 522130 primer.

1. Overview

A credit union is a not-for-profit financial cooperative — a bank-like deposit-taker owned by the members who use it. Members pool their savings (held as "shares" rather than deposits) and the institution lends that money back out as auto loans, mortgages, credit cards, and small-business loans. There are no outside shareholders and no tradable stock; each member generally gets one vote regardless of account size, and any surplus flows back to members through better rates, lower fees, and dividends on share accounts rather than to investors.[1]

At the five-digit level, NAICS 52213 is a rollup category that exists only to group its detailed children. It has one: 522130. So 52213 is not a broader grouping that blends credit unions with anything else — it is the credit union industry. The single most important fact for an investor is unusual and worth stating up front: you cannot buy a credit union. They are member-owned cooperatives with no stock, no ticker, and no direct private-equity stake in the institutions themselves. Investors reach the sector only indirectly — through the public technology, payments, and services vendors credit unions buy from; through credit union subordinated debt and securitized loan pools (a fixed-income route); or by understanding credit unions as competitors and acquirers that shape the community-bank stocks they may already own. Tickers and yields are reserved for Sections 4 and 10.

2. What's inside — and why this level equals its one child

NAICS organizes the economy in a nested hierarchy: sector (2-digit) → subsector (3-digit) → industry group (4-digit) → NAICS industry (5-digit) → national industry (6-digit). NAICS 52213 sits at the five-digit level and contains a single six-digit national industry:

Because there is exactly one child, this rollup carries no aggregation of its own — every establishment, dollar, and employee counted under 52213 is also counted under 522130. NAICS keeps the separate five- and six-digit codes for structural consistency across the classification, not because they describe different populations. The distinctions that matter within the industry — federal versus state charters, single-bond versus community fields of membership, mega-institutions versus tiny volunteer-run shops — all live inside 522130 and are covered there, not at this level.[1]

For reference, credit unions' close cousins sit in neighboring five-digit industries, not here: commercial banking is NAICS 52211, and savings institutions plus other depository intermediation are NAICS 52218. Non-depository lenders (credit-card issuers, sales financing, consumer lending, real-estate credit, loan brokers) fall under NAICS 5222.[1]

3. Size — this level's rollup figures

Because 52213 equals 522130, its ground-truth federal statistics are identical to the child's. The figures below are our ingested official statistics for NAICS 52213 specifically:

The industry's own regulator, the National Credit Union Administration (NCUA), reports a larger and more current tally: about $2.43 trillion in assets, 144.7 million members, and $1.72 trillion in loans at year-end 2025, rising toward $2.48 trillion in assets and 145.8 million members in the first quarter of 2026.[4] Note that assets are a balance-sheet figure, not revenue — the $95.5 billion "receipts" number is the industry's gross income (interest plus fees).

Undercount and mismatch caveats. Two gaps matter. First, a Census "establishment" is a business location, not an insured charter, so the 19,605 establishments span far fewer institutions — NCUA counted roughly 4,250 federally insured credit unions in early 2026, and its call-report system is the authority for charter counts and balance-sheet health.[4] Second, the payroll-based Census frame misses the smallest, volunteer-run credit unions, so the 4,526-firm count understates the true number of charters. Finally, "receipts" is an awkward yardstick for a not-for-profit cooperative whose entire purpose is to return surplus to members through cheaper loans and better savings rates, so a revenue figure understates the sector's real economic footprint.

Concentration is modest and dispersed. The four largest firms took 15.1% of industry receipts in 2022, the top eight 18.6%, the top 20 25.6%, and the top 50 just 35.9% — meaning even the fifty biggest names are barely a third of the industry, with a very long tail of small institutions behind them. The Herfindahl-Hirschman Index (HHI, a standard concentration gauge) was suppressed in the published data, so no value should be inferred.[3]

4. Investable universe — where value concentrates

With only one child industry, all of this level's value concentrates in 522130 — and, as noted, none of it is directly investable equity. The largest credit unions are enormous but member-owned: Navy Federal (~$197 billion in assets, ~15.3 million members) is bigger than the next four combined, followed by names such as State Employees'/SECU (NC), SchoolsFirst (CA), PenFed (VA), and BECU (WA).[5] You cannot buy shares in any of them.

The real public exposure is the ecosystem — the vendors that sell credit unions core software, digital banking, payments, and lending tools. These are ordinary public stocks, though each also serves banks, so exposure is partial: core processors Fiserv (NYSE: FI), FIS (NYSE: FIS), and Jack Henry (NASDAQ: JKHY) — whose "Big Three" systems run roughly half of all credit unions — plus digital-banking and lending specialists Alkami (NASDAQ: ALKT), Q2 Holdings (NYSE: QTWO), MeridianLink (NYSE: MLNK), and nCino (NASDAQ: NCNO), and payment network Visa (NYSE: V).[5] On the private side, cooperative providers such as TruStage (insurance) and Velera (payments and shared branching), plus the wider universe of Credit Union Service Organizations (CUSOs), serve the system. The full lineup and its caveats are in the 522130 primer.

5. How the money works

Credit unions earn like banks but optimize differently. The core model is spread lending: members provide shares (economically like bank deposits); the institution earns interest on loans and investments, pays dividends on shares, subtracts credit losses and operating costs, and recycles whatever remains into capital or better member pricing. Because they pay no federal income tax and answer to members rather than shareholders, they can run a thinner margin than banks and still be sound. The metrics that matter are net interest margin (the spread on loans versus shares — about 3.44% of average assets in early 2026), the net worth or capital ratio (retained earnings as a share of assets — a strong 11.26% at year-end 2025, well above NCUA's 7% "well capitalized" bar), the loan-to-share ratio (about 81.5%), delinquency and charge-off rates (roughly 1% and 0.8%), and return on average assets. There is no earnings per share, book value per share, or dividend yield in the equity sense — a member's "return" shows up as cheaper borrowing and higher savings yields.[4] See 522130 for the full walk-through.

6. Demand drivers

The same forces drive the whole level because it is one industry: consumer lending appetite (auto loans and mortgages are the backbone; loans grew 4.6% in 2025), the interest-rate cycle (which widens or compresses margins), membership growth (the sector added about 2.4 million members in 2025), a "flight to member-owned" narrative during banking scares, rising demand for digital capability (which is exactly why the vendor ecosystem is growing), and shared cooperative infrastructure that lets small institutions offer broad access.[4] Full detail is in 522130.

7. Regulation

The industry runs on the Federal Credit Union Act of 1934. Federal credit unions are chartered and examined by the NCUA, which also runs the National Credit Union Share Insurance Fund (NCUSIF) — the credit union analogue to the FDIC (Federal Deposit Insurance Corporation) — insuring at least $250,000 per member per ownership category, backed by the full faith and credit of the United States. State-chartered credit unions are supervised by state regulators, usually alongside NCUA insurance. The defining and most contested feature is the federal corporate income-tax exemption: credit unions pay none because they are not-for-profit cooperatives, a benefit banks argue is unfair and that recurs as a political flashpoint in every tax cycle. Other key rules include field-of-membership limits, an interest-rate ceiling (temporarily 18% through September 10, 2027), and bank-style capital, anti-money-laundering, and consumer-protection supervision. All of this is covered in full in 522130.[1][4]

8. Consolidation

The number of credit unions falls every year — from roughly 4,455 to 4,287 federally insured institutions during 2025, and toward about 4,250 by early 2026 — even as assets and membership rise. The driver is steady, non-distress merger: small credit unions lacking the scale to afford modern technology and compliance fold into larger ones. The headline trend is credit unions buying banks: cash-rich, tax-advantaged credit unions became aggressive acquirers of small community banks, hitting a record 22 announced deals in 2024 before easing slightly in 2025. On the trade-association side, the two historic lobbies merged on January 1, 2024 into America's Credit Unions.[4] Because the level equals its one child, these dynamics are the industry's dynamics; the 522130 primer has the specifics.

9. Risks

The risks are those of the single child industry: interest-rate and margin risk (a mismatch between long fixed loans and rate-sensitive shares); credit risk (harder to absorb than at a bank, since capital can only be rebuilt from retained earnings); liquidity risk; the existential policy risk that the tax exemption is repealed, which would raise every institution's cost structure overnight; technology and vendor-concentration risk (heavy reliance on a few core processors); and top-end concentration (Navy Federal alone is roughly 8% of industry assets, though the NCUSIF backstops members). See 522130 for the complete list.[4]

10. How to invest and the outlook

There is no direct-equity way in. The practical routes are all indirect: vendor stocks (Fiserv, FIS, Jack Henry, Alkami, Q2, MeridianLink, nCino, Visa) as the cleanest public proxy — though each also serves banks, so exposure is partial; community-bank stocks as the mirror trade, since credit union acquisitions support takeover premiums while shrinking the listed universe; and fixed-income and private routes — subordinated debt from large credit unions, auto/consumer loan securitizations (ABS), CUSO equity or debt, and private cooperative providers such as TruStage and Velera. Deposits are a product, not an investment.[4][5]

Outlook. The base case is more of the same: steady asset and membership growth, relentless consolidation of small institutions, and continued bank acquisitions by the larger players — a tailwind for both the vendor ecosystem and community-bank sellers. Near-term earnings hinge on the rate cycle (margin) and the consumer credit cycle (charge-offs, which bear watching after a 2025 uptick). The wildcard is Washington: any serious move against the tax exemption would reprice the sector's economics. For most investors, NAICS 52213 — like its one child, 522130 — is a large, healthy, growing industry you participate in around the edges, never head-on. Own the picks-and-shovels, not the miners.
