439 U.S. 299 (1978)
Marquette National Bank v. First of Omaha Service Corp is a landmark case in banking law, particularly in how it intersects with federal regulations regarding interest rates.
Can a national bank charge interest rates based on the laws of the state in which it is located, even if those rates exceed the maximum allowed in the borrower's state?
Under the National Bank Act, national banks are allowed to charge interest rates in line with the laws of the state where they are located, thereby precluding state usury laws where the borrower resides if they conflict.
The Supreme Court held that national banks can charge interest rates based on the laws of their home states, thereby allowing First of Omaha to charge Nebraska's permissible rates to borrowers in Minnesota.
The decision in Marquette National Bank v. First of Omaha Service Corp. set a precedent for the interstate operation of credit card and loan interest rates, fundamentally influencing the credit industry and consumer banking. It encouraged banks to relocate to states with more lenient usury laws, which led to increased competition and the growth of the credit card industry. This case is essential for law students as it illustrates the concept of federal preemption and the impact of federal law over state regulations in banking.
