Global Bond Selloff Accelerates: 30-Year Yield Hits 2007 High as Inflation Fears Spike

The bond market rout accelerated sharply at week's end, driven by a toxic cocktail of geopolitical oil shocks, rising inflationThe rate at which prices rise across an economy. data (PPI hit 6%), and the sudden realization that central banks may need to tighten rather than ease. US 30-year yields touched 5.11%, the highest since 2007, while yields across G-7 sovereigns surged in tandem.

In the US, Fed funds futures flipped from pricing rate cuts to pricing a hike by December, reflecting the shift in the inflation narrative. This regime change blindsided consensus: Wall Street had priced in an easy 2026, and the pivot has been swift and brutal.

Semiconductors bore the brunt as their earnings become riskier; yields on corporate bonds are widening, and credit spreads are widening faster than stocks can adjust. The cross-asset hit is pronounced: equities' traditional bull-run narrative (AI capex, soft landing) collides with bond markets' hard-landing narrative (sticky inflationThe rate at which prices rise across an economy., no cuts).
