Yup and their CMA is better than the big 4 banks offerings. Get HYSA equivalent rates but just use it like normal checking, not having to shuffle stuff around like with Citi or BoA

Fidelity isn't a bank, but they sure act a lot like a bank with the CMA account. Arguably enough like a bank that it will work as a bank for most people.

Other brokerages do the same sorts of things, Fidelity isn't alone in this. Schwab went a different way and decided to just buy a bank. Instead of like the BOA/Chase versions, where they bought a brokerage.
