The global bond selloff is accelerating as inflationThe rate at which prices rise across an economy. expectations remain sticky and energy prices refuse to cool. Investors are fleeing government bonds across the US, UK, and Japan simultaneously, a rare coordinated phenomenon that signals a structural repricing of real yields. The backdrop is straightforward: Iran war disruptions have closed the Strait of Hormuz, oil remains above $80-85/barrel, and central banks are signaling they may need to tighten further rather than cut rates as consensus expected just months ago.

The debate centers on whether inflation is transitory (oil shock only) or structural (labor markets tight, supply disruptions persist).

The equity implication is material: rising real yields compress PE multiples, especially for high-multiple growth and AI names that have driven the year's rally. If Treasury yields break above 4.5-5%, equity breadth could deteriorate sharply, particularly in EM and growth-sensitive sectors. The tech-heavy Nasdaq has already shown signs of concentration weakness as bond yields rise.
