AI Selloff, French Debt Crisis, and Oil Spike Ignite Biggest Treasury Rally Since SVB

AI Selloff, French Debt Crisis, and Oil Spike Ignite Biggest Treasury Rally Since SVB

TREE NEWS reports: A sharp selloff in AI-linked technology stocks on Thursday triggered the most powerful single-day rally in U.S. Treasuries in more than three years, as investors scrambled for safety amid a confluence of mounting risks. The yield on the 10-year Treasury note plunged 19.3 basis points to 4.952%, falling back below the 5% threshold and marking its largest one-day decline since March 10, 2023, when the Silicon Valley Bank crisis roiled markets. Only 15 trading days in the past decade have seen moves of this magnitude, encompassing events such as the 2020 pandemic crash, the 2023 regional banking crisis, the April 2025 tariff shock, and the February 2026 U.S.-Israel conflict with Iran.

The rally was not confined to the long end. The 2-year yield fell 18.8 basis points to 4.635%, its biggest daily drop since August 1, 2025, while the 30-year yield declined 15.1 basis points to 5.286%, the largest since August 2024. The 5-year and 7-year maturities each fell by as much as 20 basis points.

Three Forces Converge

Market participants pointed to a rare simultaneous eruption of three distinct pressures. “Middle East escalation, France’s deteriorating situation, and rising doubts about AI—you’re seeing multiple stresses blow up at once,” said Robert Tipp, global head of credit at PGIM. “On a normal day, a decent move is a few basis points. Today you’re seeing triple that.”

First, the AI earnings season has delivered a series of disappointments. Lam Research posted strong results but failed to exceed implicit expectations, with no clear upside to guidance. Tesla cut its full-year capital expenditure guidance from over $25 billion to about $20 billion. Meta raised the lower bound of its full-year capex guidance to $135 billion, implying fourth-quarter spending alone of $49-59 billion—raising doubts about execution. Meta has now joined Amazon in negative free cash flow territory.

Second, France’s sovereign debt crisis deepened. The French 10-year yield briefly hit 5.142%, the highest intraday level since June 2002, before closing at 5.082%. The spread over German Bunds widened to more than 170 basis points, the highest since the 2011 euro crisis. More strikingly, the French 10-year yield briefly traded about 50 basis points above Italian debt—a historically unprecedented inversion. French credit default swaps exceeded 100 basis points for the first time since 2012.

Third, oil prices surged amid escalating Middle East tensions. Houthi attacks on Saudi Arabia and a drone strike on Saudi Aramco’s Shaybah field pushed WTI crude toward its Iran-war high of $100 per barrel, while Brent crude reclaimed $112.

Market Implications: Growth Shock, Not Inflation

The simultaneous surge in oil and Treasuries signals that investors are interpreting higher energy prices as a threat to growth rather than a driver of inflation—a more ominous sign for risk assets than the index declines themselves. Rate hike expectations have also moderated; markets now fully price a 25-basis-point hike in January rather than December.

“If these pressures hit a market that wasn’t pricing persistent Fed hikes, it would be different,” Tipp said. “But now that the market has priced several hikes, you have a situation where the market will start to question whether the Fed can continue hiking in coming quarters.”

Equities reflected the rotation. The Nasdaq fell 2.6%, the Philadelphia Semiconductor Index dropped over 7%, with Intel and AMD down more than 8%. The S&P 500 lost 1.5%, but the equal-weighted index posted its best day relative to the cap-weighted benchmark since July 2024, as defensive sectors like healthcare and utilities rallied. Hedge fund data showed the most crowded long-short portfolios fell about 4.2%, the worst single-day drop since 2011.

In credit markets, the AI capital expenditure retrenchment is reducing potential bond supply. “The reflexivity is remarkable—the very thing causing problems in stocks is helping to solve the problem in rates,” noted Rich Privorotsky of Goldman Sachs. However, data center CDS spreads have surged to record highs, and the iTraxx Europe Crossover index rose to 329 basis points, the highest in nearly seven months, indicating contagion to broader credit.

Key Takeaways for Investors

• Safety bid intact: Despite recent yield volatility, Treasuries remain a haven. The flight to quality is likely to persist as long as French political risk and Middle East tensions remain unresolved.
• AI trade under pressure: The market is repricing the AI capex cycle. Companies reliant on external financing may face higher costs, and free cash flow will become a key differentiator.
• Growth concerns dominate: The bond market’s reaction to higher oil prices suggests investors fear a growth slowdown. Watch for further moderation in rate hike expectations.
• Credit contagion risk: Rising CDS spreads for data centers and hyperscalers warrant monitoring, as credit stress could spill over into broader markets.
• Rotation underway: Defensive sectors are outperforming, and hedge fund positioning suggests further de-risking in crowded AI trades.
