The purpose of Regulation Z is to

Regulation Z, part of the Truth in Lending Act (TILA), was enacted to ensure that consumers are fully informed of the true cost of borrowing. It requires lenders to disclose credit terms, including the annual percentage rate (APR), finance charges, payment schedule, and total repayment amount.

The purpose is not to control or limit credit (A), regulate or set interest rates (B or C), but to provide transparency. This allows borrowers to compare loan offers on equal terms.

In Massachusetts, lenders must comply with both federal TILA (Regulation Z) and state consumer protection laws (M.G.L. Chapter 140D – Massachusetts Truth in Lending). Borrowers receive a Loan Estimate and Closing Disclosure summarizing credit costs, ensuring informed financial decisions.
