Global Bond Selloff Accelerates: US 30Y Yield at 2007 High, Inflation Fears Drive Risk-Off

The bond market staged a historic reversal Friday, and equities felt the sting. US Treasury yields spiked across the curve, with the 30-year settling at 5.11 percent, the highest since May 2025 and nearing levels not seen since the 2007 credit crisis. The sell-off was synchronized globally: UK gilt yields climbed, euro-zone bunds rallied, and Japanese JGBs sold off. What triggered the rotation was not dovish Fed surprise; it was inflationThe rate at which prices rise across an economy.. Oil prices remained elevated on Iran supply risks, CRB commodities stayed bid, and inflation-expectations indices ticked higher. Consensus flipped overnight: instead of pricing Fed rate cuts, traders now model a real possibility of rate hikes over the next 12 months.

The mechanical impact on equities was swift and brutal. On Friday, May 15, SPY and QQQ both posted losses as higher rates depress terminal multiples and make risk-free Treasury yields competitive again with stock dividends. Semiconductor and mega-cap tech names that had led the prior six weeks of rallies (NVDA up 20 percent since May 5, but down 2-3 percent on the day; TSLA off 3.5 percent) felt the worst pressure. Even names with strong earnings visibility, like AAPL, retraced as durationBond price sensitivity to interest rate changes. became toxic. The rotation was brutal: Russell 2000 outperformed large-cap benchmarks as lower-duration, higher-dividend small-cap plays offered shelter from yield shock. Gold (GC) remained supported as inflationThe rate at which prices rise across an economy. hedge, but silver (SI) collapsed, a sign of forced liquidations in growth portfolios.

The macro narrative is now inverted. For weeks, traders bet on a soft landing and AI capex boom insulating equities from rates. That thesis broke when real yields climbed sharply, signaling the bond market is not convinced inflationThe rate at which prices rise across an economy. will fade. Fed officials, including incoming Chair Kevin Warsh, face a regime change: instead of managing a pivot to cuts, Warsh inherits a market pricing hikes. JPMorgan strategists warned that 5 percent yields would challenge equity bull cases. Bank of America's Hartnett flagged June as a danger month for profit-taking. Goldman Sachs moved up rate hike odds. The 30Y at 5.11 percent is a hard ceiling for P/E multiples; no amount of AI enthusiasm can paper over that math.

The downside risk: if inflationThe rate at which prices rise across an economy. stays sticky (driven by war, energy, or broad wage-price loop), central banks will have no choice but to hike or hold, crushing the equity rally's foundation. Conversely, if oil prices fall and energy supply recovers, yields could reverse. But for now, the bond vigilantes are back, and equities are repricing risk.
