American Express Bank offers a high yield savings account that can be described in one word: convenient. One can access their account by phone or online any time of the day, with very few fees or penalties to have to deal with. What is especially great about the savings account offered by American Express Bank is that there is no minimum deposit requirement. For a high yield savings account one does not find this feature very often. With everything being done electronically, the transfer times are some of the fastest in the industry. One cannot go wrong with opening a savings account from American Express Bank.
