Quote from drsteph:
I keep my accts with BOA largely because of their excellent online payments capability. Of course, when I noticed that my brokerage MM accts were paying, oh, say 3% MORE than my cash accounts at BOA, you can be pretty sure that most of those funds didn't stay there.
BOA is really quite niggardly on their interest payments. That's where they seem to be making their $$, along with other fees ($9.95 a month to use quicken with them - FOR WHAT?).
I did a little parusing for the sake of one of my swing accounts. BofA offers the Columbia family of funds for money market sweeps, currently yielding 5.15% which isn't too shabby (better than most). Margin rates were slightly lower than their ilk, but obviously not near FedFunds+100bp. All in all, worth checking out for the non-active trader.
