Can banks seize your money if the economy fails?

While the FDIC insures deposits up to $250,000, meaning your money is generally safe if a bank fails in a crisis, a legal mechanism called "bail-in" authority exists under U.S. law (Dodd-Frank Act) that could allow failing banks to convert large deposits into equity (essentially seizing funds to recapitalize the bank). Although not implemented in the U.S. yet, this "bail-in" concept has been used elsewhere, creating concern, though many experts believe regulators would prevent the system collapse it would cause. For typical accounts, deposits are protected, but large, uninsured amounts carry more risk in extreme scenarios, making diversification across banks a wise precaution.
