30-Year US Yields Hit 2007 Highs, Global Bond Rout Halts Equity Rally

The week that started with tech megacaps at all-time highs ended with a violent reversal as global bond markets convulsed in fear of sustained inflationThe rate at which prices rise across an economy.. US 30-year Treasury yields climbed to 5.11%, their highest level since May 2025, and in some international markets even higher, as oil prices spiked on Iran geopolitical tensions and traders abandoned the assumption that central banks would cut rates later this year. The result was a sharp repricing of risk assets, with the Nasdaq down 1.3% Friday while the Russell 2000 actually rose, signaling a dramatic rotation out of growth and into value.

The immediate trigger was a cascade of inflationThe rate at which prices rise across an economy. signals: energy prices surged on Middle East supply concerns, with oil flowing through the Strait of Hormuz facing renewed risk; India, facing its first fuel price hike in four years, warned of more to come; and forecasters slashed their 2026 oil-demand growth expectations in light of the Iran supply shock. Central banks from Tokyo to Frankfurt watched as their long-dated bond yields rose faster than policy rates, inverting traditional relationships and signaling market skepticism that rate cuts will materialize. Treasury futures, the primary hedging tool for bond portfolios, threatened to become dislocated from spot prices, prompting warnings from analysts that the bond market's plumbing could strain under the volume of selling.

Meanwhile, inflationThe rate at which prices rise across an economy.-linked bonds and real assets (including commodities, energy stocks, and defensive plays) suddenly became attractive again. The rotation highlighted that the narrative of "AI capex replacing all other market drivers" was premature; macro risks (inflation, rates, oil) remain dominant. Gold, long-dated TIPS, and energy infrastructure plays are suddenly in demand again, breaking months of tech dominance.

The bull case for equities isn't dead, but it has been materially complicated. If inflationThe rate at which prices rise across an economy. persists and central banks respond with sustained high rates, the profit-margin compression in leveraged equity portfolios could be severe. If, conversely, the oil shock proves transitory and inflation subsides, the selloff offers a tactical entry point for dip buyers.
