Why U.S. Treasuries Have Become High-Risk Assets Again

U.S. Treasury yields keep climbing as research shows bond prices now move in the same direction as stocks, breaking the classic hedge. This means the foundational framework of global asset allocation faces a structural reset.
How did bonds start behaving like stocks?
Research by Carolin Pflueger, associate professor at the University of Chicago and resident scholar at the Chicago Fed, finds that bonds are showing increasingly "equity-like" behavior — their correlation with stocks has flipped from negative to positive.
In plain terms = stocks and bonds used to move in opposite directions, cushioning each other. Now they rise and fall together.
This means → bonds are no longer a portfolio's "airbag" — they have become another risk exposure.
What does a broken hedge mean for ordinary investors?
If government bonds can no longer offset equity risk, the classic stock-bond portfolio — think the textbook 60/40 mix — loses its core logic.
This means → the entire cross-asset risk-management framework needs rebuilding; investors must find new assets that protect when equities fall.
The safe-haven premium bonds once commanded will also fade. Put simply = the market stops paying extra for "safety" once it is no longer safe.
What is the key variable?
Pflueger points to the Fed's "reaction function" — how the market expects the Fed to trade off between inflation and growth.
The core logic: only when markets believe the central bank will prioritize crushing inflation can bonds resume their hedging role. Once that trust wavers, the equity-like trend in bonds persists or deepens.
This reflects a deeper issue: bond risk properties ultimately hinge on market confidence in central-bank credibility, not on the interest-rate number alone.
Is this sell-off a cyclical blip or a lasting shift?
Government bond markets are under pressure globally, with yields climbing well beyond the U.S.
The core question for the next phase: is the yield rise cyclical volatility, or a structural repricing of bond risk?
In plain terms = if it is cyclical, bonds return to "safe asset" status after the storm. If it is structural, the asset-allocation textbook of the past few decades may need rewriting.
