Several U.S. government agencies play important roles in regulating and protecting different parts of the financial system. The FDIC focuses on banking and helps protect consumers from bank failures. The SEC oversees the securities markets and works to ensure fair and efficient trading. The IRS is responsible for collecting taxes and enforcing tax laws, while the CFPB monitors how financial institutions interact with consumers, especially in areas like credit cards, loans, and mortgages. Each agency has a distinct mission but contributes to maintaining public trust in the U.S. financial infrastructure. Understanding who does what can help consumers know where to turn when issues arise—whether it’s reporting fraud, understanding taxes, or ensuring their money is safe in a bank. Learning the functions of these institutions is a key step in building confidence and competence in your personal financial life.
