Are rising bond yields driven by real yields rather than inflation expectations?
Core argument: US 30-year fixed mortgage rates are back above 7% as bond yields return to 2007 levels, a rise the evidence attributes more to a “good” pickup in growth than to other widely cited causes.
The rise in bond yields looks alarming and has had a horrible effect on US mortgages, with 30-year fixed rates back above 7%. But the evidence is that the overall rise in yields is more a response to a “good” rise in growth, rather than to other widely cited potential causes. Consumers’ inflation concerns have risen since the Iran war drove up oil prices nearly seven months ago, but longer-term market-based inflation expectations have barely budged. Yields can be broken into real and inflation-driven components using the gap between fixed income and inflation-protected bonds (TIPS). Inflation breakevens barely budged over the last five years; real yields are now higher and account for all of the rise of the last five years. To illustrate that differently, negative real yields drove the exceptionally easy financing conditions of 2021. That’s now totally reversed.
