Tech Stocks Slide as Surge in Treasury Yields and Geopolitical Tensions Weigh on AI Sentiment

Macroeconomic pressure and escalating conflict in the Middle East dragged major Wall Street indexes to two-week lows on Tuesday, with technology equities taking the brunt of the selloff as long-term U.S. Treasury yields hovered near historic peaks. First reported by Yahoo Finance, the Nasdaq Composite dropped 1.05 percent as high borrowing costs rattled equity investors and heightened scrutiny over capital expenditures across the tech sector.

U.S. government bond yields pulled back slightly during Tuesday trading but remained around multi-year high points. The yield on the 30-year U.S. Treasury bond traded down 2.32 basis points at 5.2868 percent after spiking earlier to 5.3371 percent, reaching its highest level since 2007. Meanwhile, benchmark 10-year Treasury note yields dropped 1.6 basis points to 4.708 percent after hitting 4.7478 percent, their highest level since January 2025.

The climb in yields persisted despite recent soft economic data in the U.S. that had previously muted expectations for near-term interest rate hikes by the Federal Reserve. Financial market traders currently price in a 35 percent probability of a rate increase at the Fed's September policy meeting, alongside a 68 percent chance of a rate hike by December. However, fresh energy-driven supply shocks could reinvigorate inflationary pressures and prompt central bankers to resume interest rate hikes.

Energy markets reflected intensifying geopolitical risks on Tuesday, as U.S. crude futures gained 0.82 percent to reach $85.17 per barrel and Brent crude increased 0.55 percent to $91.37 per barrel, marking three consecutive sessions of gains. Crude prices pushed upward after diplomatic prospects for a U.S.-Iranian deal weakened, following statements from Tehran indicating a more aggressive stance and Washington ruling out any extension of ceasefire terms.

"We're living in this world where we're going to have supply shock after supply shock," said Will Compernolle, macro strategist at FHN Financial. Analysts also noted that escalating expenditures linked to the ongoing conflict with Iran are adding to wider market concerns regarding the overall path of the U.S. fiscal deficit.

Global bond dynamics added further upward pressure on yields, as Japanese government bond yields surged to 30-year peaks. Yields on Japan's 10-year note approached the 3 percent mark for the first time since the mid-1990s, while European sovereign yields also remained near multi-year highs. Analysts warned that higher domestic yields could prompt Japanese institutional funds to reallocate capital out of U.S. Treasuries and back into home-country bonds.

The sustained rise in debt yields has created a challenging backdrop for public technology companies, which rely on low-cost capital to finance long-term buildouts in artificial intelligence and cloud computing infrastructure. High yields diminish the relative attractiveness of growth equities while raising borrowing expenses for capital-intensive enterprises.

"The yields are troubling people because it portends a tighter environment and it's going to be more expensive to borrow money," said Kim Forrest, chief investment officer at Bokeh Capital Partners. "Especially in this whole AI thing where time to pay it back is uncertain. It makes for a nervous investor environment."

Beyond the tech-heavy Nasdaq, the Dow Jones Industrial Average dropped 0.12 percent and the S&P 500 shed 0.50 percent, while the CBOE Volatility Index touched its highest level in more than a week. Investors are now awaiting Wednesday's release of the Federal Open Market Committee's meeting minutes and next week's Jackson Hole conference. Jonas Goltermann, chief markets economist at Capital Economics, noted that "given the reduced information content of the FOMC's policy statement and Fed chair (Kevin) Warsh's press conferences, the minutes from the FOMC meetings arguably have become more important in conveying the balance of views among policymakers."
