US 30Y Yield Hits 5.11 pct; Highest Since May 2025: AI Stock Frenzy Threatened

The bond market delivered a sharp warning to equity traders this week as the US 30-year Treasury yield surged to 5.11 pct, the highest level since May 2025, amid a global selloff sparked by war-driven oil prices and sticky inflationThe rate at which prices rise across an economy. readings. JPMorgan's chief investment officer noted that 'bond vigilantes' are back, actively pricing in expectations that central banks will delay or abandon rate cuts. The selloff in sovereign bonds has rippled through equities, with investors cognizant that rising yields compress valuation multiples on high-growth tech stocks that have anchored the recent rally.

UBS warned that global oil stockpiles could hit record lows if the waterway remains closed, creating stagflationary pressure that the Fed cannot easily offset with stimulus.

Friday saw a sharp repricing: the S&P 500 pulled back as yields accelerated, with semiconductors (AMD down 3 pct, NVDA down 3 pct) and growth names absorbing losses while the Russell 2000 gained 0.7 pct. This rotation signals a shift from mega-cap concentration risk toward cyclicals and value. Goldman Sachs cautioned that the equity rally, while underpinned by AI fundamentals, has also been goosed by multiple expansion that is now vulnerable to yield volatility. Morgan Stanley noted that hedging costs in FX and rates markets have shifted, potentially redirecting $200 billion in flows away from equities into fixed income.

The debate centers on whether this is a healthy correction or a warning shot.

However, traders in fed funds futures are now pricing the first rate hike as soon as December, removing the soft-landing narrative that had supported AI valuations. The CME FedWatch tool shows zero probability of a June cut and rising odds of a December hike.
