Kinda depends I guess... The 10 year US bond is often used as a risk free rate and it's about 2.2% right now if I remember correctly, and it's been as high as 3% in the past five years. And of course you can sell bonds too so it's not like they're illiquid, it's generally known as one of the most liquid markets on the planet. But there's a bit more risk than than a 3 month bill of course which is also used as a risk free rate indicator quite a lot, and that's really low with inflation being so low right now. Anyway I wouldn't call 4% incredible but it's definitely good and something many would be quite happy with.
