Why does the American tax payer have to pay interest on money loaned to failed banks?

American taxpayers may have to pay interest on money loaned to failed banks due to the government's role in stabilizing the financial system. When banks fail, the Federal Deposit Insurance Corporation (FDIC) or other governmental entities often step in to cover losses and protect depositors, which can involve borrowing funds. The government typically funds these interventions through taxpayers, as they back the financial system. This ensures that the broader economy remains stable, but it can result in taxpayers bearing some of the financial burden.
