Credit Intermediation & Related Activities

NAICS 522 covers institutions that lend money and service credit — commercial banks, savings institutions, credit unions, mortgage companies, sales finance firms, and non-depository credit intermediaries. JPMorgan Chase, Bank of America, and Wells Fargo anchor the depository side, while non-bank originators like Rocket Mortgage and United Wholesale Mortgage have captured roughly two-thirds of residential mortgage volume since 2020 according to the Urban Institute.

The subsector's economics hinge on net interest margin — the spread between what institutions earn on loans and pay on deposits. After the Federal Reserve's 2022-2023 rate-hiking cycle pushed the federal funds rate above 5%, community banks in states like Texas, Ohio, and Georgia reported margin expansion, but unrealized losses on held-to-maturity bond portfolios triggered the March 2023 failures of Silicon Valley Bank and Signature Bank. Those collapses prompted the FDIC to propose a special assessment on banks with assets above $5 billion and accelerated the Fed's review of supervisory standards for mid-size institutions.

Regulatory architecture is layered: the OCC charters and supervises national banks, the FDIC insures deposits and resolves failures, the Federal Reserve oversees bank holding companies, and the CFPB enforces consumer-protection statutes including the Truth in Lending Act and the Equal Credit Opportunity Act. State banking departments add licensing and examination authority for state-chartered banks and non-bank lenders. The CRA modernization rule finalized in late 2023 updates how regulators assess community reinvestment performance for the first time in nearly three decades.
