It's generally not smart to keep all your money in one bank, especially large amounts, due to FDIC insurance limits ($250k/depositor/institution), risk of technical failures/fraud, and missing out on better rates elsewhere; however, some consolidation offers convenience, better interest rates (with high balances), and streamlined management, so a balanced approach with diversification for large sums and separate accounts for goals is often best.

Should you keep all your money in one bank?

Depositing all of your money in one single bank is never a good idea. If that bank has a problem and the accounts are frozen, you cannot access your money. Worse yet, if that bank is wiped out, your money is gone with it. Diversify. Have as many banks as you can conveniently keep track of. Spread out your money.

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.
