People are really starting to worry the Fed is going to invert the curve. Historically, an inverted curve (short rates above long rates) has been a pretty good recession indicator. I don’t have a particularly strong opinion about the direction of interest rates, especially now that we are above 2% on the 2-Year. But I do think this chart is telling us something.
If the curve is basically flat from 7 years on out to 30 years, that is not exactly a ringing endorsement of long-term growth and inflation prospects. I’ve heard from some fixed income people that it’s demand for long-dated paper from overseas buyers holding the 30-year yield down. I’ll buy that. But it’s still telling us something about supply and demand for capital along various time horizons.
Namely: we’ve got an awful lot of long duration capital out there looking for a home, and not enough opportunities to absorb it all.
