What Are Usury Laws?

Usury laws limit the amount of interest that can be applied to different types of loans, such as credit cards, personal loans, and payday loans. Most states have the authority to regulate and enforce usury laws rather than relying on federal intervention. The laws regarding usury differ among states, meaning interest rates can vary greatly depending on your location. Certain banks charge the highest legal interest rate permissible in the state where they were established, disregarding the interest rates in the state where you reside. This practice has been permitted since a U.S. Supreme Court decision in 1978.


Usury laws in the United States govern the permissible interest rates on loans, safeguarding consumers against excessive charges. Each state individually establishes its usury laws, setting maximum interest limits to protect borrowers.

While the Constitution's commerce clause could potentially encompass such financial activities, Congress historically hasn't prioritized usury regulation. However, the federal government views the collection of usury through violent means as a severe offense.

Ways to Circumvent Usury Laws

Financial institutions, including credit card companies and nationally chartered banks, often use state incorporation to bypass usury laws. They can charge interest rates based on the state where they are incorporated rather than adhering to the usury laws of the borrowers' states. States like Delaware and South Dakota, known for their lenient usury regulations, are particularly favored by these lenders.

Delaware, in particular, attracts numerous financial institutions seeking the freedom to charge higher interest rates. Nearly half of the domestic credit business in the U.S. is conducted by companies incorporated in Delaware, even if they have operational headquarters elsewhere.

Rethinking the Impact of Usury Laws: Supreme Court Rulings and State Strategies

Following landmark decisions by the U.S. Supreme Court, there has been ongoing debate about the effectiveness of usury laws. In the case of Marquette National Bank v. First of Omaha Corp., the Court ruled in favor of credit companies, permitting them to charge customers out-of-state at the same interest rates they could apply in their home states.

Delaware's Financial Center Development Act further intensified financial institutions' interest in moving to the state. By eliminating limits on fees and interest for consumer lending, Delaware became an attractive destination for banks seeking to evade usury laws. To benefit from this favorable regulation, banks merely needed to establish subsidiaries or fulfill specific incorporation conditions in the state. Consequently, some other states responded by modifying their usury laws, granting locally-based financial institutions the authority to charge interest rates comparable to those of out-of-state lenders.


Usury laws set limits on loan interest rates, protecting consumers from excessive charges. States regulate these laws independently, resulting in varying rates across regions. Financial institutions exploit state incorporation to bypass usury restrictions. A 1978 Supreme Court decision permitted this practice, leading to ongoing debates about the laws' effectiveness. Delaware's lenient regulations have attracted a significant share of the credit business, influencing other states to reconsider their usury laws. Overall, usury laws remain a critical topic in the financial landscape.
