A broad retreat from technology equities worldwide on Thursday pushed investors toward lower-risk holdings, pulling Treasury yields down sharply and wiping out the upward movement that had followed a stronger-than-anticipated reading on U.S. inflation. Trader expectations for a steady Federal Reserve policy rate at the October gathering held firm, even as fresh concerns about climbing borrowing costs circulated through the market.

The 10-year U.S. Treasury yield settled at 5.104%, a drop of 1.6%, pulling back from a Wednesday evening peak of 5.333%. Across the 20-year maturity, the yield retreated by 1.3 percentage points to settle at 5.503%, and a matching decline of 1.3 percentage points brought the 30-year rate down to 5.455%. In five-year territory, Treasury yields edged down to 4.908%, a drop of 1.7%.

Treasury yields had moved higher on Wednesday after September's consumer price index printed modestly above analyst projections, a development that then weighed on stock prices through the trading session. Data pointing to a firmer economic reading has fed into market talk that the Federal Reserve may lift borrowing costs before 2026 draws to a close. Futures market pricing drawn from CME FedWatch placed the odds of a 25-basis-point rate rise in December at roughly 70.6%.

Inflation figures landed just above forecasts, doing little to shift market expectations for a rate hold when policymakers convene in October. Appetite for U.S. Treasury bonds and gold picked up as questions about the trajectory of technology and artificial intelligence equities left market participants seeking steadier ground.

Concern about the direction of interest rates — and how a prolonged period of elevated borrowing costs might weigh on earnings forecasts for prominent technology and AI companies — pulled equities lower across multiple markets. A number of firms swept up in the AI funding boom are carrying debt levels that leave them exposed should interest rates rise. Valuation concerns and tightening financing conditions prompted a pullback across the technology segment, with share prices retreating as investors adjusted their positions.

The Nasdaq Composite shed roughly 1.9% on Wednesday, a loss that formed part of a broader retreat across equity markets globally. Selling spread widely across Asian markets on Thursday, with South Korea's KOSPI recording a decline of roughly 8% — a move large enough to trigger a lower circuit breaker — led by losses concentrated in semiconductor and technology stocks.

Competing pressures across bond markets came into focus as Treasury yields swung into a notable reversal. Persistent inflationary pressure in the United States has kept rate-hike expectations alive, while turbulence across equity markets has driven fresh appetite for Treasury bonds. The direction of Treasury yields is linked to three variables unfolding in tandem: decisions coming out of the Federal Reserve on monetary policy, the readings that incoming inflation figures produce, and the prevailing mood running through equity markets worldwide.
