Global stock markets ended a week of sharp volatility amid a striking regional divergence in performance, as US and Asian exchanges declined while European markets held firm. These shifts were driven by higher-than-expected US inflation data, which reignited concerns over the massive debt funding the artificial intelligence infrastructure boom.

Global performance divergence and US inflation pressures
According to a detailed analysis by Daniela Hathorn, senior market analyst at Capital.com, global stock markets wrapped up a difficult and grueling week with a measure of relative stability and caution. However, the fundamental difference in financial performance across geographic regions has become sharper and more pronounced than ever before. Stock indexes in both the United States and the Asian continent suffered the heaviest and most severe losses during the week’s trading following the release of US inflation data that came in higher than prevailing expectations among economic analysts.
This sudden spike in inflation rates led to a tangible jump in US Treasury yields, which practically means an increase in the financial return demanded by investors in global markets in exchange for lending to the US government. The impact of this yield surge was not limited to government debt instruments; it also forcefully brought back investors’ deep concerns regarding the extent to which the current AI boom relies heavily and excessively on borrowing and debt financing within a high-interest monetary environment.
Nasdaq decline and CoreWeave’s debt crisis
The analysis showed that the US Nasdaq index, which heavily comprises major and emerging tech companies in its core components, was the most vulnerable and sensitive to these fast-paced financial developments. Investors and fund managers have begun raising fundamental and legitimate questions about whether the future earnings and returns expected from AI technologies will actually be enough to justify the extremely high valuation levels of these tech stocks, especially amid steadily rising borrowing and debt-servicing costs.
Cloud computing specialist CoreWeave sat at the center of this storm of market concerns after required yields on some of its debt instruments and bonds jumped to critical levels clearly indicating strong and mounting financial pressures. This alarming development prompted global financial markets to conduct a comprehensive review and careful reconsideration of the credit and financial standings of AI infrastructure companies that heavily rely on high-cost loans and debt to finance their capital expansion plans and data center construction.
European markets outperform thanks to traditional and defensive sectors
In contrast, European exchanges painted a completely different picture, with financial markets on the continent posting the best regional performance overall during last week’s trading. The striking paradox highlighted by Daniela Hathorn is that Europe benefited this time directly from a structural factor previously viewed as a weakness and strategic shortcoming: the limited exposure of its financial markets to the feverish investment wave in AI and supercomputing centers.
European benchmark indices feature a much higher proportion of companies operating in established traditional and defensive sectors, led by healthcare and pharmaceuticals, financial and banking services, as well as the industrial and manufacturing sectors. These economic sectors are known to be more stable and less vulnerable to the sharp price volatility hitting high-valuation tech stocks. Furthermore, European stock prices and valuations remain relatively less inflated compared to their US counterparts, providing investors with an additional layer of protection and hedging as global bond yields rise.
Despite this positive performance, the report noted that the European continent still faces undeniable structural and economic challenges, including weak macroeconomic growth rates, growing fiscal pressures on member states’ public budgets, and ongoing political uncertainty in several European capitals. Nevertheless, this week’s performance practically demonstrated the utmost importance of portfolio diversification across different economic sectors and geographic markets rather than over-reliance and heavy concentration on a small number of major US tech companies.
Jensen Huang’s reassurances and the decisive test for tech giants’ earnings
Toward the end of the trading week, AI stocks received a dose of support and relative relief after Jensen Huang, CEO of semiconductor giant Nvidia, stepped in to calm escalating market fears regarding CoreWeave’s situation. Huang stated that the company’s financial position is steadily improving, emphasizing that Nvidia does not need to provide any additional financial support or exceptional guarantees to bail it out. Immediately following these reassuring remarks, the company’s stock managed to recover and bounce back from its lowest price levels, while tech stocks in Asian markets regained their footing to post notable gains on Friday.
Capital.com’s analysis concluded that Huang’s remarks successfully eased short-term anxiety and defused the immediate crisis, but they did not provide a definitive answer to the core and more important question currently plaguing Wall Street: can the massive capital expenditure boom on AI infrastructure continue—despite its structural reliance on massive debt—at a time when returns on safe, low-risk investments have surpassed the 5% threshold? Therefore, the upcoming real test will arrive with the kickoff of quarterly earnings season for tech giants, where these companies must prove with numbers that their record AI spending can generate actual revenue and strong cash flows to justify the scale and rising cost of these investments.
