I remember in 1989, after I changed local banks, I opened a linked MM savings account linked to my checking account. On the monthly statement, it showed the annual interest rate which in May of 1989 was around 7.6%, nice. But, sadly, that rate dropped every month the rest of the year so by the end of the year I remember it being around 2% (if even that high). This, along with my savings being rebuilt after my moving to a co-op apartment I had just bought, led me to begin investing elsewhere with my after-tax dollars, starting with a muni bond fund which not only paid a higher return but was also triple-tax-free.
