30-Year Yield at 2007 High: Bond Selloff Halts Equity Rally as Inflation Spikes

The bond market's violent selloff this week marks a critical inflection point for the equity rally that has dominated 2026. Government bond yields surged globally, with the US 30-year climbing to 5.11 percent and two-year yields reaching levels that suggest traders have priced out rate cuts and are beginning to price in hikes.

This repricing of discount rates is particularly punishing for high-growth and mega-cap technology stocks that have benefited from years of low-for-longer yield expectations. Friday's session saw the Nasdaq Composite decline 1.3 percent versus a modest Russell 2000 gain of 0.7 percent, a textbook risk-off move that favors value and small-cap over growth. Semiconductor stocks, which had been leading the AI enthusiasm, sold off sharply, with AMD down 3 percent, Micron down 5 percent, and Broadcom under pressure. Even mega-cap defensive names like Microsoft and Apple found support but showed little conviction.

The implications ripple across asset classes. Credit spreads are widening as investors demand higher yields for risk, corporate bond issuance is being delayed, and currency volatility has picked up. The Morgan Stanley foreign exchange team warned that hedging costs for the euro have compressed, potentially triggering large currency flows that could add to market friction. Private credit markets, which have grown to $1.8 trillion in size, are seeing increased trading activity as investors reassess tail risk and collateral values.

The next critical data point is May CPI, expected the week of May 21, which will either validate or undermine the inflation narrative now priced into yields.
