Glen's Verdict

Former hedge fund manager, current index fund enthusiast

High-yield savings for most people. Here's why: the rate difference between a top HYSA and a CD is usually tiny — maybe 0.25-0.50% — and you give up all liquidity for that marginal gain. If you have money you absolutely won't need for 12+ months, a CD ladder makes sense to lock in rates. But your emergency fund? Never put that in a CD. I keep 6 months of expenses in a HYSA at an online bank and don't overthink it. The difference between 4.5% and 5.0% on $30,000 is $150 a year. Not worth losing sleep — or access to your cash — over.
