Credit Union Capital Requirements and Net Worth Categories

Every federally insured credit union has to hold a minimum amount of capital relative to its size, and the credit union capital requirements set by the National Credit Union Administration (NCUA) turn on a single number: the net worth ratio. A credit union needs a net worth ratio of at least 7% to be classified as Well Capitalized, and anything below that triggers progressively stricter federal oversight. Below 2%, the NCUA can step in and take over.¹ Large credit unions face a second test on top of the net worth ratio.

The Five Capital Categories

Federal regulations sort every credit union into one of five tiers based on its net worth ratio. The tier determines what the institution can and cannot do.¹

Well Capitalized. Net worth ratio of 7.0% or higher. The credit union operates with minimal restrictions.
Adequately Capitalized. At least 6.0% but below 7.0%. The credit union must start rebuilding net worth by at least 0.1% of total assets each quarter until it returns to Well Capitalized.²
Undercapitalized. At least 4.0% but below 6.0%. Asset growth and lending restrictions kick in, and the credit union must file a formal restoration plan.
Significantly Undercapitalized. At least 2.0% but below 4.0%. Tighter restrictions apply and the NCUA gains broader discretionary authority.
Critically Undercapitalized. Below 2.0%. The most restrictive oversight applies, and conservatorship or liquidation become real possibilities.

One trap worth knowing: a credit union whose ratio sits between 4.0% and 5.0% can be dropped into the Significantly Undercapitalized tier if it misses the deadline for its restoration plan or materially fails to follow an approved one.¹

How the Net Worth Ratio Is Calculated

The ratio itself is simple: net worth divided by total assets, expressed as a percentage rounded to two decimal places.³ What goes into each half is where the detail lives.

Net worth, for regulatory purposes, is essentially the credit union’s retained earnings balance under generally accepted accounting principles. It includes undivided earnings and reserve accounts that represent the institution’s ownership equity.⁴ It is not the same as total assets. Total assets are everything on the books — loans, investments, cash. Net worth is only the portion the credit union owns free of liabilities, the cushion that absorbs losses before members or the share insurance fund are exposed.

Credit unions with a low-income designation get extra room. They can count the outstanding principal of subordinated debt and grandfathered secondary capital toward net worth, as long as those instruments are uninsured and subordinate to every other claim, including depositors and the National Credit Union Share Insurance Fund.³ The recognized amount of that debt phases out in the five years before maturity, so a credit union cannot lean on debt that is about to come due.⁵

For the denominator, a credit union can choose among four measures of total assets each quarter: the quarter-end balance, the average daily balance, the average of the three month-end balances, or the average of the current and three preceding quarter-end balances.³ The choice matters. A credit union with a temporary spike near quarter-end may prefer an averaging method to avoid a distorted ratio. The selected method applies to all net worth ratio purposes that quarter.

Risk-Based Capital for Credit Unions Over $500 Million

Credit unions with total assets above $500 million are classified as “complex” and face a second capital test alongside the net worth ratio.⁶ They must also calculate a risk-based capital ratio, which weights assets by how risky they are. Cash and government securities carry low weights; commercial loans and certain long-term investments carry higher ones.

A complex credit union needs both a 7.0% net worth ratio and a 10% risk-based capital ratio to qualify as Well Capitalized.⁷ Meeting the first but missing the second drops it to Adequately Capitalized. The rule is meant to keep large credit unions from loading up on risky assets while still showing a healthy overall ratio.

The CCULR Shortcut

Risk-weighted asset calculations are burdensome, so the NCUA offers a simpler alternative called the Complex Credit Union Leverage Ratio (CCULR). A qualifying complex credit union can skip the full risk-based capital calculation if it maintains a CCULR of 9.0% or higher. The CCULR is calculated the same way as the standard net worth ratio.⁸

Eligibility requires meeting all four of these conditions on the most recent Call Report:

CCULR of 9.0% or greater
Off-balance-sheet exposures at 25% or less of total assets
Combined trading assets and liabilities at 5% or less of total assets
Goodwill and other intangible assets at 2% or less of total assets

A credit union can opt in or out at the end of any quarter. If it later falls out of compliance, it gets a two-quarter grace period and remains Well Capitalized as long as its CCULR stays at or above 7%. The grace period does not apply if eligibility is lost through a non-supervisory merger or acquisition; in that case the standard risk-based capital rules apply immediately.⁸

What Happens When Capital Falls Short

The NCUA is required by law to impose progressively stricter measures as capital erodes, a framework called Prompt Corrective Action. The restrictions escalate at each tier, and credit unions have limited room to negotiate them away.

Earnings Retention

From the Adequately Capitalized level downward, a credit union must grow its net worth by at least 0.1% of total assets each quarter until it is back above 7.0%.² The requirement sounds modest, but for an institution with thin margins and a cap on growth, carving out that reserve each quarter can squeeze operations hard.

Net Worth Restoration Plans

Any credit union classified as Undercapitalized or worse must file a written Net Worth Restoration Plan with its NCUA Regional Director within 45 calendar days of the classification taking effect.⁹ The plan has to lay out a quarterly timetable for reaching at least 6.0% and staying there for four consecutive quarters. If the classification worsens and the NCUA asks for a revised plan, the window shrinks to 30 days, followed by a final 15-day notice before further consequences.

Asset Growth and Lending Limits

Once a credit union is Undercapitalized, total assets cannot exceed the prior quarter’s level unless the NCUA has approved its restoration plan and the growth fits that plan.¹⁰ Without an approved plan, growth is permitted only in narrow categories like cash, receivables, and existing loan commitments. The credit union also cannot pay above-market share rates or open new branches. Member business lending is frozen at the current level of outstanding loans and unused commitments.

Dividend Restrictions

The board cannot pay a dividend or interest refund that would push the credit union’s classification below Adequately Capitalized unless the Regional Director gives prior written approval.¹¹ A request for that approval must include a plan for eliminating any negative retained earnings. Dividends can only come from net worth after special reserves are subtracted, so a credit union running thin has very little to distribute.

Critically Undercapitalized

Below 2.0%, everything above applies plus more. Starting 60 days after classification, the credit union cannot make principal or interest payments on any subordinated debt.¹² The NCUA gains broad discretionary powers: it can prohibit asset growth outright, restrict transactions with credit union service organizations, order new board elections, dismiss directors or senior executives, and require the institution to shut down lines of business that pose excessive risk. If the trajectory does not improve, the NCUA can place the credit union into conservatorship or liquidation.

A Healthy Ratio Is Not a Guarantee

Capital classification is not driven by the ratio alone. The NCUA can reclassify a Well Capitalized credit union down to Adequately Capitalized, or push an Adequately Capitalized or Undercapitalized institution one tier lower, based on supervisory findings.¹ This happens when the agency determines the credit union is operating in an unsafe or unsound condition, or when the credit union has failed to correct a material unsafe or unsound practice it knew about or should have known about. The institution gets notice and a hearing before any reclassification, but the point stands: a strong net worth ratio does not override deteriorating operations.

Different Rules for New and Small Credit Unions

Credit unions less than ten years old with $10 million or less in total assets are classified as “new” and fall under a separate set of capital categories with different thresholds.¹³ Once a credit union reports more than $10 million on any Call Report, it permanently graduates to the standard framework, even if assets later drop back below that line. Credit unions under $10 million, regardless of age, can request NCUA help preparing required business plans, and “new” credit unions are eligible for the agency’s Small Credit Union Program for additional compliance support.
