The Federal Bureau of Investigation (FBI) is America’s top law enforcement agency, tasked with investigating federal crimes ranging from cybercrime to terrorism and financial fraud. While the FBI may investigate illegal activity involving banks — such as embezzlement or wire fraud — it does not provide any kind of insurance for bank deposits. The responsibility for insuring funds in your checking or savings account lies with the FDIC, a specialized agency that protects depositors in the event of a bank’s failure. The FBI may be involved in protecting the financial system from criminal threats, but it won’t refund your money if a bank collapses. That’s the specific domain of the FDIC, which exists solely to promote confidence and security in the U.S. banking system. Confusing the FBI’s law enforcement role with financial insurance can lead to a false sense of protection if you don’t understand which agency does what.
