One reason to use a MM is accessibility & no penalties for early withdraw. I assuming most people use a MM in a brokerage account inbetween investments/trades, including IRA’s, and do not want their money tied up.
With that said, the yield on those CD’s are great, especially considering the looming rate cut.
It also shows the desperation for funds that CFC is offering such a high rate, of course its better than paying 11% and it doesn’t convert into equity… 🙂
