30-Year Treasury Yield Hits 5.11%; Global Bond Rout Halts Equity Rally

A violent global bond selloff dominated Friday's session, with U.S. 30-year Treasury yields jumping to 5.11 percent, the highest level since May 2025. The rout extended across developed markets: gilts tumbled in the UK, Bunds weakened in Germany, and Japan's 10-year rose sharply, signalling a broad retreat from government debt. The trigger was a combination of Iran war supply concerns pushing oil prices higher, persistent inflationThe rate at which prices rise across an economy. signals, and growing conviction that central banks will hold rates elevated longer than previously priced.

Equity markets buckled under the pressure. S&P 500 futures fell approximately 1 percent at the open Friday, halting a weeks-long rally that had pushed the index to record highs. Nasdaq futures underperformed as growth and technology stocks, which benefit most from lower rates, bore the brunt of selling pressure. Semiconductor stocks, which had led the AI-driven rally (with Nvidia up 20 percent in just ten days), sold off sharply: AMD fell 3.3 percent, Nvidia retreated 2.2 percent, and Memory chip names like Micron declined 5 percent. The Russell 2000 was the day's relative winner, up 0.7 percent versus Nasdaq's 1.3 percent decline, reflecting a rotation away from durationBond price sensitivity to interest rate changes.-sensitive mega-cap growth into value and cyclical exposure.

The macro implication is stark: the "Fed put" and low-rate environment that had underpinned the AI rally is now in question.

JPMorgan and other banks noted that 5 percent yields would challenge stock valuations; RBC's Lori Calvasina warned that multiple compression is likely if yields sustain above that level. The bond market is now the driver of equity repricing, not corporate earnings or AI optimism.

The question for traders is whether this is a healthy correction within a bull market (a pullback in stretched valuations) or the start of a regime shift toward durationBond price sensitivity to interest rate changes. risk and stagflation. Historical precedent suggests that when 30-year yields approach 5 percent, equities typically struggle until either growth disappoints enough to force Fed cuts or fiscal policy changes.
