What is the member business loan limit for credit unions?

The lesser of 1.75 times the credit union's actual net worth or 1.75 times the net worth required to be well capitalized, under 12 CFR 723.8. With the 7 percent well capitalized ratio, that equals 12.25 percent of assets for a credit union above that ratio.

Do participations count toward the MBL cap?

Non-member participation interests a credit union buys do not count. Participations it sells without recourse that qualify for true sale accounting reduce its net member business loan balance. Purchased participations still count toward concentration limits in the credit union's own policy.

Can credit unions make commercial real estate loans?

Yes. Commercial real estate loans are commercial loans under Part 723, subject to the credit union's board-approved policy, the single borrower limit, collateral and guarantee standards and, for most, the aggregate MBL cap.

What is the single borrower limit for credit union business loans?

The greater of 15 percent of net worth or $100,000, plus an additional 10 percent of net worth if the excess is fully secured by readily marketable collateral. Insured or guaranteed portions of government program loans are excluded.

Do credit unions require personal guarantees on business loans?

Part 723 does not require one outright. If a credit union does not obtain the full personal guarantee of the controlling principals, it must determine and document in the loan file that other factors offset the risk.

Which credit unions are exempt from the MBL cap?

Credit unions with a low-income designation, those participating in the CDFI program, those chartered to make business loans, and those that had a history of primarily making business loans when the Credit Union Membership Access Act was enacted in 1998.

Is a $250,000 business loan a commercial loan at a credit union?

Size alone does not decide it. Some credit unions market loans above $250,000 as commercial, but under Part 723 any business-purpose loan is a commercial loan once the relationship reaches $50,000, unless an exclusion such as 1 to 4 family security applies.

How does credit union business lending work under NCUA rules?

The short answer

Credit unions make business and commercial real estate loans under NCUA's rule at 12 CFR Part 723. The rule does two jobs. It sets the program a federally insured credit union must have before it lends commercially: board oversight, qualified staff, a written commercial loan policy, collateral and guarantee standards, and construction loan controls. It also carries the statutory cap on member business loans, which limits net member business loan balances to the lesser of 1.75 times the credit union's actual net worth or 1.75 times the net worth required to be well capitalized.

Not every commercial loan counts toward that cap. Fully government-guaranteed loans, non-member loans and non-member participation interests a credit union buys are commercial loans but not member business loans. Loans secured by 1 to 4 family residential property are not commercial loans at all under Part 723. Some credit unions are exempt from the cap altogether. Concentration risk is managed through board-set limits as a percentage of net worth, which examiners test at every exam.

Why do most guides skip the rules?

Search for credit union business lending and the results are product pages: loan programs, rate ranges, terms up to some number of years. They answer a borrower's question. They do not explain why a credit union's commercial lending looks the way it does, which is a function of the regulation as much as of appetite.

For a CRE sponsor, a broker or a bank competing for the same deal, the rulebook explains the behavior: why one credit union holds a $10 million loan and sells half as participations, why another asks for a personal guarantee every time, and why an exempt low-income credit union can grow its book faster than its neighbor.

What is the difference between a commercial loan and an MBL?

Part 723 uses two terms. A commercial loan is any loan, line or letter of credit, including unfunded commitments, to individuals or businesses for commercial, industrial, agricultural or professional purposes. Excluded are loans secured by 1 to 4 family residential property, loans fully secured by shares or deposits, loans secured by vehicles manufactured for household use, loans to other credit unions or CUSOs, and relationships whose aggregate balance is under $50,000.

A member business loan is the subset that counts toward the statutory cap. Section 723.8 takes the commercial loan definition and removes loans a government agency fully insures, guarantees or commits to purchase, non-member loans and non-member participation interests acquired properly, and loans fully secured by a 1 to 4 family dwelling. Household-use vehicle loans used for business are the reverse case: not commercial loans, but MBLs once the aggregate relationship reaches $50,000.

What does NCUA Part 723 require?

The table summarizes each section of the rule and what it means on a commercial lending desk. It is a reading aid, not legal advice; credit unions apply the rule with their counsel and their examiner.

12 CFR Part 723 at a glance
Section	Rule	What it means on the desk
723.1	Scope; credit unions under $250 million in assets with commercial loans under 15% of net worth are exempt from 723.3 and 723.4	Small programs skip the board and policy sections but still face the cap and collateral rules
723.2	Definitions: commercial loan, associated borrower, common enterprise, control (25% voting), loan-to-value	Relationship aggregation drives the single borrower limit
723.3	Board approves and annually reviews the policy; credit union must have qualified staff or a qualified independent third party	The loan decision must stay with the credit union even if a CUSO underwrites
723.4	Written commercial loan policy: loan types, trade area, concentration limits, single borrower limit, approval authority, underwriting, risk rating	Single borrower limit is the greater of 15% of net worth or $100,000, plus 10% more if fully secured by readily marketable collateral
723.5	Collateral commensurate with risk; no full personal guarantee from controlling principals requires documented mitigation	The file must explain why an unsecured or unguaranteed loan is still sound
723.6	Construction and development loans: collateral value is the lesser of cost to complete or prospective market value	Budget review before closing, inspections before each draw, a lien check on every disbursement
723.7	Prohibited loans to senior lending staff and their families; independence of third parties	Insider and conflict checks belong in the credit file
723.8	Aggregate MBL cap: lesser of 1.75x actual net worth or 1.75x the well capitalized minimum; exclusions and statutory exemptions	Participations sold without recourse reduce the net MBL balance
723.10	State-chartered credit unions follow an NCUA-approved state rule where one exists	Check which rule applies before comparing two credit unions

How is the member business loan cap calculated?

The cap is the lesser of 1.75 times the credit union's actual net worth or 1.75 times the minimum net worth required under the Federal Credit Union Act to be well capitalized. NCUA's capital rule sets the well capitalized net worth ratio at 7.0 percent, so for a credit union above that ratio the second test works out to 12.25 percent of assets, and for one below it the first test binds.

The balance measured against the cap is the net MBL balance reported on the Call Report: outstanding balances plus unfunded commitments, less any portion secured by shares, by deposits in other institutions or by a member's primary residence, less government-insured or guaranteed portions, and less participations sold without recourse that qualify for true sale accounting. Selling participations is the main lever a credit union near the cap has, which is why credit unions are steady sellers in participation networks.

Four kinds of credit union are exempt from the cap: those with a low-income designation, those in the CDFI program, those chartered to make business loans, and those with a history of primarily making business loans as of the 1998 Credit Union Membership Access Act.

How do credit unions handle CRE concentration?

Part 723 does not set a numeric CRE concentration ceiling. It requires the board's policy to set maximum amounts, relative to net worth, for commercial loans overall and by category. NCUA's Examiner's Guide expects limits by loan type, including income-producing and owner-occupied commercial real estate, construction and development, and C&I by industry, tied to the strategic and net worth plans. It says concentrations above 100 percent of net worth must be monitored carefully, with a documented board rationale.

In practice, examiners compare the limits in the policy to the actual portfolio, then look at reporting: whether the board receives concentration, risk rating, exception and watch list reports. A credit union that wants to grow CRE starts with the policy and the reporting, then the staffing, because the NCUA exam will test all three.

How do credit unions underwrite CRE loans?

Section 723.4(f) sets the floor: financial analysis deep enough to judge debt service capacity, due diligence on principals and their related interests, borrower projections when history does not support the debt, financial statement quality matched to the relationship, collateral methods with loan-to-value limits, and environmental due diligence. Section 723.4(g) adds covenants, periodic loan review, a credit risk rating at inception, and exception tracking.

For income property, coverage is the first test. A DSCR calculator shows quickly whether NOI supports the proposed debt at the credit union's policy minimum. The rest of the credit file has to show the same discipline the policy promises, because examiners sample against the policy, not against market practice.

faster closings after moving commercial loan closings to a shared workspace

Where do credit union commercial closings slow down?

Credit unions often run commercial lending with a small team that originates, underwrites, closes and services. Closing work competes with everything else, and the file has to satisfy both the borrower and a future examiner. The usual drags are participation documents with partner credit unions, third-party reports, and conditions that live in email.

Many credit unions run origination in an LOS and coordinate the closing elsewhere. The Prodeal vs nCino comparison explains the difference between a loan origination system and a closing workspace that the borrower, title and counsel can work in directly. The NCUA exam preparation guide covers how to keep those files exam-ready.

What should a credit union commercial program get right?

Five things carry most of the weight with examiners and with borrowers alike. None of them requires a new system; all of them require someone to own them, and a credit union commercial team shows that best by naming the owner of each one.

A policy that matches the book
Concentration and single borrower limits the board actually reviews against reports.
Aggregation of associated borrowers
Common enterprise and control tests applied before approval, not after.
A credit file that explains exceptions
Unsecured, unguaranteed or high LTV loans with mitigation written down.
Cap monitoring
Net MBL balance tracked monthly against 1.75x net worth, with participation sales planned ahead.
One closing record
Conditions, documents and approvals in one place, ready for the examiner who asks for the file.
