Major U.S. Banks Cap CD Returns at 4.00% APY

A depositor earns a promised return rate that remains constant regardless of the broader rate environment. This is the result of the largest U.S. banks, measured by FDIC figures, posting CD APYs that top out at 4.00%. Available terms for these rates range from two to 14 months. To secure this rate, a depositor commits a set amount of money for a specific term. Accessing those funds before the term ends results in early withdrawal penalties.
