Nasdaq Sets Record as AI Rally Outruns Rising Yields and France’s Fiscal Strains Hit the Euro

By MediaFare Editorial Desk

The Nasdaq Composite set a record on Monday, October 5, as investors continued buying large technology and artificial-intelligence companies despite a sharp rise in long-term borrowing costs. The advance exposed a striking split in global markets: equity investors remained willing to pay for the expected profits of AI infrastructure and software, while bond and currency markets signaled greater concern about inflation, government borrowing and political risk.

The Nasdaq gained about 1.1% on Monday, according to Associated Press market coverage (https://apnews.com/article/7f89624b604f25f313502c77d4d0b010), setting a record as technology shares led the U.S. session. The Dow Jones Industrial Average rose about 0.2%. A separate Reuters market report (https://www.marketscreener.com/news/nasdaq-hits-record-as-dollar-and-treasury-yields-climb-oil-prices-ease-ce785dd8db8efe27/) also described the Nasdaq reaching a record while Treasury yields held near multiyear highs, the dollar advanced against the euro and oil prices eased.

The rally was led by the market’s continuing enthusiasm for AI-linked growth. Companies building data centers, advanced computing systems and related software continue to attract capital because investors expect demand for computing capacity and AI services to remain strong. That outlook has helped the largest technology companies absorb, at least temporarily, the valuation pressure normally created by higher interest rates.

Corporate deal news added to the positive tone. Schneider Electric’s proposed $22.6 billion cash acquisition of software company PTC helped lift the broader software group, according to Reuters coverage. The transaction reinforced an important feature of Monday’s trading: investors were rewarding companies associated with strategic technology spending even as the cost of capital rose.

That divergence deserves caution. Higher Treasury yields increase the discount rate applied to future corporate earnings, which normally weighs most heavily on richly valued growth stocks. The continued advance in AI-related shares therefore suggests that investors currently regard the expected expansion of AI profits as more important than the immediate valuation effect of higher rates. It does not remove the risk that the relationship could reverse if yields continue climbing or if earnings fail to justify current prices.

The 10-year Treasury yield rose to roughly 5.31% on Monday from 5.28% late the previous week, according to AP. Market data cited by Yahoo Finance (https://finance.yahoo.com/markets/stocks/articles/nasdaq-composite-reaches-high-10-203243452.html) put the session high at about 5.35%. The 30-year yield was also elevated, underscoring that the pressure was concentrated in longer-dated government debt rather than limited to expectations for the Federal Reserve’s next meeting.

Long-term yields can rise for several reasons at once. Investors may expect stronger economic activity, more persistent inflation, heavier government borrowing or a larger supply of Treasury securities. They may also demand greater compensation for holding long-duration bonds when fiscal policy appears less predictable. Monday’s market action reflected that mixed message: U.S. growth and business investment, particularly in AI infrastructure, supported equities, while bond investors demanded higher returns to lend over longer periods.

Recent labor-market data added another layer to the debate. A softer-than-expected payrolls report reduced expectations of an immediate Federal Reserve rate increase, but it did not produce a sustained rally in long-term bonds. A weaker employment report can lower expectations for near-term policy rates, while persistent inflation concerns, strong capital spending or fiscal borrowing can still push longer-term yields higher.

The dollar strengthened as the euro weakened, providing another indication that investors were differentiating between the United States and Europe. The euro fell to a 17-month low against the dollar on Monday as markets focused on France’s budget deficit, political uncertainty and rising borrowing costs. Reuters market coverage published through Euronext (https://live.euronext.com/en/financial-news/euro-hits-17-month-low-dollar-near-pre-liberation-day-highs) said concerns about France’s ability to stabilize its public finances helped drive the currency lower.

France’s difficulties do not amount to an immediate sovereign-debt crisis. But investors are demanding a higher premium to hold French government bonds, and the political environment complicates efforts to reduce spending or raise revenue. France is approaching a 2027 presidential election, making fiscal consolidation more politically difficult at precisely the moment when debt-service costs are rising.

The most closely watched measure is the spread between French and German 10-year government bonds. Germany’s Bund is generally treated as the euro area’s benchmark safer sovereign asset. When French yields rise faster than German yields, the spread indicates that investors are assigning a larger country-specific risk premium to France.

Reuters reported that the French-German spread widened to about 150 basis points on Friday, October 2, its highest level since the euro-area sovereign-debt crisis in 2011, before narrowing to roughly 140 basis points on Monday. A related Reuters report (https://www.investing.com/news/economy-news/french-bond-contagion-fears-are-rattling-the-euro-4932638) said the stress was beginning to affect broader euro-area risk pricing, with the Italian-German spread also rising sharply.

The concern is less about France suddenly losing market access than about a feedback loop. Higher yields increase the cost of refinancing maturing debt. Rising interest expenses make it harder for the government to meet deficit targets. Political resistance to austerity can then weaken investor confidence further, producing still-higher yields. If that process spreads to other highly indebted euro-area countries, the European Central Bank could face a difficult balance between containing market fragmentation and maintaining its inflation-fighting stance.

The euro absorbs some of that stress because it trades continuously and reacts quickly to changes in expectations. A weaker currency can support exporters, but it also raises the local-currency cost of imported energy and other commodities. That matters when oil prices remain volatile. Oil prices eased on Monday after recent gains, according to Reuters’ market summary, offering some relief to consumers and importers. The decline did not eliminate the broader inflation and fiscal risks associated with energy costs.

For U.S. markets, the central question is whether the AI rally can remain insulated from the bond market. Technology companies may continue to outperform if earnings growth and capital spending confirm the investment thesis. But rising yields eventually affect corporate financing, household borrowing and equity valuations across the market. A stronger dollar can also reduce the value of overseas earnings for multinational companies and tighten financial conditions for borrowers outside the United States.

Investors are therefore watching several indicators together: the 10-year and 30-year Treasury yields, inflation data, corporate earnings revisions, AI-related capital expenditure and credit-market spreads. In Europe, the French-German bond spread and the euro’s exchange rate will provide a running measure of whether France’s fiscal concerns remain contained or begin influencing broader euro-area risk pricing.

Monday’s action was bullish on the surface but not uniformly reassuring. The Nasdaq’s record showed that investors still had strong appetite for AI-linked growth. The bond market’s selloff showed that the cost of money remains a constraint. The weaker euro and elevated French risk premium showed that political and fiscal credibility are becoming increasingly important in the global allocation of capital.

The immediate lesson is not that equities have defeated interest rates. It is that markets can reward a narrow group of companies for a compelling growth story while simultaneously charging governments and borrowers more to access capital. That divergence can persist, but the next phase of the rally will depend more heavily on evidence: sustained AI earnings, manageable inflation, stable Treasury demand and a credible French budget strategy.
