Interest Rate War
Back in Sept. I wrote an little about the interest rate war. Well it has now broken the 4% barrier. Looking at the latest Money Magazine The top five Bank Money-Market Rates range from 4.1% to 4.5%. Given that I like banks I have heard of before, and for most people a small minimum is preferable I'd pick E-Trade Bank from their list (4.1% with $100 minimum).
So it is worth shopping around to see where the best rates are. And given the lag in published magazines, it is possible that somewhere there are rates better than this.
