The legislative program established during the Great Depression that helped shape consumer lending policies and convinced commercial banks that consumer credit could be a profitable industry was the National Housing Act of 1934.

What the program did

The National Housing Act created the Federal Housing Administration (FHA) , which insured mortgages for banks and other lenders. By reducing the risk that lenders would lose money on home loans, the FHA made it safer and more attractive for commercial banks to extend consumer credit, especially for home purchases.

How it shaped lending and helped consumers

  • It standardized mortgage terms and appraisal practices, which made consumer lending more predictable and less risky.
  • Lower down‑payment requirements and longer repayment periods made homeownership more accessible, encouraging banks to see installment and mortgage lending as a stable, profitable business line.

In short, the National Housing Act of 1934 turned consumer credit—particularly mortgage lending—into a mainstream, bank‑driven industry rather than a niche or high‑risk sideline.
