Research Question

Which US industries draw the most Small Business Administration lending activity, and how does SBA concentration relate to industry margin and payroll?

Methodology

We queried PlainBizBench's sba_industry and sba_lenders tables — the former is the NAICS-keyed aggregate (total_loans, total_amount, avg_loan_amount, total_jobs_supported, top_lender), the latter is the 92,214-row lender-level breakdown. We joined SBA activity against the industries table to compare lending intensity with IRS SOI margins and Census CBP payroll per employee.

Banking-regulatory and capital-formation reference notes

Banking framework governing small-business lending: Federal Reserve Regulation H, Regulation O, and Regulation Y govern member-bank operations and bank-holding-company permissible activities. Office of the Comptroller of the Currency (OCC) supervises national banks; FDIC supervises state-chartered nonmember banks; Federal Reserve supervises state-chartered member banks and bank holding companies. National Credit Union Administration (NCUA) supervises federally-chartered credit unions; state regulators supervise state-chartered credit unions. Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 created the Consumer Financial Protection Bureau (CFPB), reorganized regulatory authority across primary federal regulators, and established stress-testing requirements under the Comprehensive Capital Analysis and Review (CCAR) and Dodd-Frank Annual Stress Test (DFAST) frameworks. Basel III capital rules apply standardized and advanced-approaches risk-weighting to credit exposures including small-business loans (typically 100% standardized risk weight versus 75% for qualifying retail exposures under Basel II). Community Reinvestment Act (CRA) of 1977 evaluates bank performance in meeting credit needs of low-and-moderate-income (LMI) communities through Lending, Investment, and Service tests; the 2023 CRA modernization rule expands assessment areas to include digital-deposit jurisdictions. Equal Credit Opportunity Act (ECOA) Regulation B Section 1071 small-business lending data collection requires covered lenders to report 81 data points per credit application including applicant demographics, principal-owner race/ethnicity/sex, gross annual revenue, and credit decision. Regulation 1071 phased compliance dates depend on lender size: tier-1 (highest-volume) lenders begin reporting October 2024, tier-3 (smallest covered lenders) begin January 2026. Truth in Lending Act (TILA) and Regulation Z disclosure requirements apply to consumer-purpose credit but generally exempt commercial credit. Uniform Commercial Code (UCC) Article 9 governs secured-transaction perfection through UCC-1 financing-statement filings at the state secretary-of-state office. Bankruptcy Code Chapter 7 (liquidation), Chapter 11 (reorganization including Subchapter V small-business reorganization), and Chapter 13 (individual debt-adjustment) provide debtor-protection and creditor-recovery frameworks. Securities Act of 1933 Regulation D Rule 506(b)/(c) and Regulation Crowdfunding (Reg CF) under the JOBS Act of 2012 provide securities-registration exemptions for small-business equity capital formation. Regulation A+ Tier 1 (up to $20M) and Tier 2 (up to $75M) offerings allow mini-public offerings without full S-1 registration.

What this analysis cannot tell us

SBA 7(a) and 504 loan data reflects loan approvals, not disbursements or repayment performance. The top_lender field records the single lender with the most 7(a) approvals per NAICS code but does not capture market share or loan dollar volume by lender. Charge-off rates in sba_industry reflect historical cumulative rates across the 2020-2026 fiscal-year window and do not isolate single-year performance. NAICS 425120 (Business to Business Electronic Markets) is a specialized code with structural lending needs that do not generalize to all Wholesale Trade.
