The nation’s largest banks are subject to the most stringent liquidity standards among U.S. banks. These standards ensure that the largest U.S. banks have sufficient liquid resources, such as cash, to meet liquidity needs such as when customers withdraw money from their accounts. Since 2009, the U.S. GSIBs have tripled their liquid assets, allowing them to remain strong and continue to lend and support the economy in the face of headwinds.
