US Treasury yields tumbled sharply on Thursday as investors moved into government bonds amid growing concerns about artificial intelligence spending, technology stock valuations and Europe’s worsening fiscal outlook.
The benchmark 10-year US Treasury yield fell below 5%, closing at its lowest level in more than a month as demand for safe-haven assets intensified.
Selling pressure across global equity markets, combined with mounting uncertainty surrounding France’s public finances, encouraged investors to shift capital toward relatively safer government securities.
US Treasury Yields Record Sharp Declines Across Bond Market
The selloff in yields extended across the US Treasury market, affecting short-, medium- and long-term government bonds.
The 10-year Treasury yield dropped 19.8 basis points to 4.951%, marking its lowest closing level since September 17.
Meanwhile, the 30-year Treasury yield declined 15.1 basis points to 5.286%, its lowest close since September 9.
The shorter-term, interest-rate-sensitive two-year yield also weakened significantly, falling 17.5 basis points to 4.648%.
Because bond prices move inversely to yields, the sharp declines reflected increased demand for US government debt.
The widespread rally highlighted a shift in investor sentiment as market participants reduced exposure to riskier assets.
AI Spending Concerns Trigger Flight to Safe-Haven Bonds
A broad decline in technology and communication services stocks contributed to Thursday’s defensive market environment.
Investors became increasingly concerned about the enormous capital expenditures required to develop artificial intelligence infrastructure, including data centers, advanced computing equipment and related technologies.
Questions surrounding the potential returns on these investments intensified following disappointing earnings developments across parts of the technology sector.
Meta Platforms added to the discussion after updating its capital spending outlook and announcing plans to establish a new class of nonvoting shares.
The proposed share structure would provide additional financing flexibility as the company continues expanding its artificial intelligence operations.
However, investors remain concerned about the financial implications of substantial AI investments, particularly when companies rely on debt or additional capital raising to support expansion.
Technology Stocks Decline as Defensive Sectors Outperform
The shift in market sentiment produced a familiar risk-off pattern across Wall Street.
Investors reduced exposure to high-growth technology companies while increasing allocations to government bonds and traditionally defensive stock market sectors.
José Torres, senior economist at Interactive Brokers, attributed the movement to disappointing technology earnings and growing uncertainty about the returns generated by major artificial intelligence investments.
According to his assessment, stronger demand for safe-haven Treasuries contributed to falling yields while providing support for more defensive areas of the equity market.
The performance of the S&P 500 reflected this change in positioning.
Consumer staples stocks advanced more than 3%, leading gains among the index’s 11 major sectors.
Utilities followed with an increase of approximately 2%, while healthcare stocks climbed 1.3%.
These sectors typically attract greater investor interest during periods of market uncertainty because demand for their products and services tends to be less sensitive to economic conditions.
French Debt Crisis Pushes European Bond Yields Higher
Political uncertainty and growing fiscal pressures in France introduced another major source of volatility into international bond markets.
French government bond yields surged above 5%, reaching their highest levels in approximately 24 years as investors demanded higher returns to compensate for increasing sovereign credit risk.
The spread between benchmark 10-year French government bonds, known as OATs, and German Bunds widened sharply.
The difference exceeded 170 basis points during Thursday’s trading, approaching levels associated with the European sovereign debt crisis of 2011.
The widening spread reflected growing concerns about France’s fiscal stability and its ability to manage government borrowing costs.
Shorter-term French borrowing costs also increased, with the two-year government bond yield reaching approximately 3.754%, a two-week high.
France’s Budget Deficit Raises Sovereign Debt Concerns
France’s fiscal difficulties have intensified as political divisions complicate efforts to introduce spending reductions.
President Emmanuel Macron’s administration faces significant challenges in addressing a budget deficit equivalent to approximately 5.4% of gross domestic product.
Nationwide protests and disagreements over fiscal reforms have further complicated the government’s ability to strengthen public finances.
Investors are increasingly concerned that elevated borrowing costs could make France’s debt burden more difficult to manage.
Elias Haddad, senior markets strategist at Brown Brothers Harriman, warned that the yield spread between French and German government debt could potentially expand toward 250 basis points, drawing comparisons with Italy’s 2018 budget crisis.
He also highlighted the difficulties France faces in financing government spending and interest payments while attempting to stabilize its debt-to-GDP ratio.
The uncertainty has encouraged some international investors to favor US Treasuries and German government bonds over higher-risk European sovereign debt.
Italian, Greek and German Bonds Show Greater Resilience
Despite the sharp deterioration in French debt markets, several other European government bond markets demonstrated comparatively stable performance.
Italian 10-year government bond yields remained near 4.594%, supported by perceptions of a relatively more disciplined fiscal approach.
Greek 10-year yields experienced limited movement, benefiting from recent credit rating improvements and comparatively stable fiscal management.
Meanwhile, benchmark German 10-year Bund yields hovered around 3.42%, maintaining their traditional safe-haven appeal within European fixed-income markets.
The contrasting performance highlighted how investors were increasingly differentiating between European governments based on fiscal conditions, political stability and perceived credit risk.
Federal Reserve and ECB Interest Rate Decisions in Focus
Attention is now shifting toward major monetary policy decisions scheduled for October 28–30.
The Federal Reserve is widely expected to leave its benchmark interest rate unchanged at 3.75%–4.00% during its October 28 meeting.
Falling Treasury yields have already contributed to an easing of certain financial conditions by reducing market-based borrowing costs.
Meanwhile, the European Central Bank is expected to maintain its policy rate at 2.50% at its upcoming meeting.
Investors are also evaluating the possibility of additional monetary tightening later in the year.
According to market expectations described in the report, traders were pricing a probability exceeding 80% of a 25-basis-point ECB rate increase in December, potentially bringing the policy rate to 2.75%.
However, persistent energy-driven inflation and worsening financial conditions across parts of Europe could complicate the central bank’s policy decisions.
US Treasury Market Outlook Depends on Risk Sentiment
The sharp decline in US Treasury yields illustrates how quickly investor demand can shift toward government debt during periods of financial uncertainty.
Concerns surrounding artificial intelligence investment returns, weaker technology stocks and France’s sovereign debt difficulties have collectively increased demand for relatively safer assets.
At the same time, upcoming Federal Reserve and European Central Bank decisions could influence borrowing costs and investor expectations across global bond markets.
For now, the 10-year Treasury yield’s decline below 5% represents a significant development, reflecting growing caution among investors despite continued uncertainty surrounding inflation and monetary policy.
Further developments in technology earnings, European fiscal conditions and central bank guidance will likely shape the next major moves in US Treasury yields.
