Global Markets Shaken by AI Capex Skepticism and $100 Oil Surge

Global financial markets experienced a severe sell-off on Thursday as mounting skepticism over Big Tech's massive artificial intelligence expenditures coincided with geopolitical escalations pushing crude oil prices past the $100 threshold. The resurgence of inflation fears sent sovereign yields soaring, driving a rapid risk-off rotation across asset classes.

The AI Reality Check: Alphabet and Tesla Trigger Capex Anxiety

■Despite Alphabet's robust fundamental earnings, its elevated capital expenditure (capex) outlook prompted intense investor scrutiny regarding the actual return on investment for AI.

■Tesla CEO Elon Musk declared 2026 as a "massive capex year" dedicated to Optimus robots, robotaxis, and data centers, further spooking growth-sensitive investors.

■Led by these "Magnificent Seven" heavyweights, the tech-heavy Nasdaq Composite plummeted 2.1%, briefly breaking below the key 25,000 level for the first time since May, while the S&P 500 dropped 1.2%.

Geopolitical Escalation Re-ignites Inflation and Bond Market Sell-Off

■International benchmark Brent crude crossed $100 per barrel following Houthi attacks on Red Sea tankers, raising fears of a wider regional conflict.

■The energy price spike triggered a sharp sell-off in sovereign debt, sending the US 10-year Treasury yield to its highest level in 18 months as inflation expectations surged.

■Adding to the hawkish pressure, US initial jobless claims unexpectedly fell to 187,000—the lowest level since 1969—effectively dampening market bets on imminent Federal Reserve rate cuts.

We are witnessing a classic, high-velocity "risk-off" transition in global capital flows. The premium valuations fueled by the AI narrative are facing their first real structural test as markets begin to penalize aggressive capex guidance that threatens near-term free cash flow. Crucially, the convergence of an energy supply shock and an incredibly tight US labor market is forcing a repricing of the term premium in the bond market. As yields march higher, macro hedge funds are rapidly unwinding leveraged risk positions, driving a liquidity migration toward cash and short-duration assets. This liquidity squeeze is likely to persist until the geopolitical premium stabilizes.
