Is the money market still the best place for my $50k?
Yes, but barely. You're earning 4.55% in the MMA. 4-week T-bills are paying 4.78% right now and are state-tax-free. For you, the after-tax pickup is about $115/year on $50k. Want me to move $35k into a rolling T-bill ladder and keep $15k liquid in the MMA?
Yes.
Done. T-bill ladder opened, MMA stays above the $10k top-tier threshold so your remaining cash keeps the 4.55% rate. I'll re-evaluate every Tuesday when new bills are auctioned.
