TIPS maturing in 2046 or later are yielding slightly above 3% as of last Friday. (And TIPS maturing 2042-2045 aren’t far below 3%.)
It’s important to understand that interest rates are quite hard to predict. And there’s no rule that says that TIPS yields can’t go meaningfully above 3%. So there’s no way to say, “today is the very best time to buy.” But it is fair to say that “inflation + 3%” is a better expected return from the bond side of a portfolio than has been available for quite some time, without using lower-quality bonds.
