The 30-year US Treasury yield has crossed above 5%, a threshold Wall Street views as a fire alarm. The 10-year yield hovers near 4.5%, compounding a selloff that now looks structural.
Sticky inflation is the primary driver. Price pressures have proven resilient, rewriting expectations for monetary policy. Fed rate hike odds have risen sharply, while the probability of cuts in 2026 has fallen. Economist Ed Yardeni notes the bond market is discounting higher inflation and a Fed that may need to tighten further.
The US government's deficit trajectory has ballooned, flooding the market with new Treasury issuance at a time of waning appetite. Higher yields increase government interest costs, widening the deficit and fueling more borrowing-a self-reinforcing cycle.
For investors, 5% on a 30-year Treasury offers the highest income in over a decade. Key variables to watch: inflation data releases and Treasury auction results. If both deteriorate, the 5% level may become a floor, not a ceiling.
