A for-profit service run by the Promontory Interfinancial Network, the Certificate of Deposit Account Registry Service (CDARS) allows investors to purchase certificates of deposit (CDs) across a network of multiple banks in order to access FDIC insurance beyond the $250,000 single-institution limit. When investors are looking to make a CD purchase that exceeds the limit, the bank they are using will employ the CDARS system in order to locate multiple CDs that can accommodate the customer’s needs.
