Dear Carol,
Thanks for the question.
Most banks will not make that mistake. They cover themselves in the small print with words to the effect that the interest rate is not gauranteed, or is subject to change and or market conditions.
In the event your banks money market account manager did not have you sign those documents or make them available, or in the unlikely event they gaurnateed a rate of return, then you would have cause of actino to sue them to enforce the gauranteed rate.
