It's been a turbulent stretch for markets. Even after a hotter-than-expected US inflation report, investors have been buying up US Treasuries, sending bond prices higher and yields lower. At the same time, AI-linked stocks have been sliding, and credit spreads—the extra yield investors demand to hold corporate bonds instead of safe government debt—have been widening.
That combination is unusual. Typically, hot inflation data pushes bond yields up (and prices down) because it raises expectations that the Federal Reserve will keep interest rates higher for longer. But this time, the opposite happened. The move suggests something deeper is going on: a growing skepticism about the debt-fueled expansion of artificial intelligence infrastructure.
Why are AI stocks stumbling?
Over the past couple of years, AI has been the market's main engine of growth. Tech giants and startups alike have poured billions into building massive data centers, often funded by borrowing. The logic was simple: AI would generate enough revenue and productivity gains to justify the spending. But now, investors are starting to ask whether that payoff will come quickly enough—especially with inflation still sticky.
The concern is that if AI projects don't generate returns fast, the debt taken on to finance them could become a burden. That's why we're seeing AI stocks slide, even as the broader market holds up relatively well. The Nikkei plunged nearly 5% recently, driven by AI stock losses and fears about debt at CoreWeave, a cloud computing company that has borrowed heavily to build AI infrastructure. Similar pressure has hit Chinese tech stocks and other Asian tech markets.
Bonds are acting like hedges again
For much of the past few years, bonds and stocks often moved in the same direction—both falling when inflation surged, because higher rates hurt both. That made bonds a poor hedge. But this week, Treasuries rallied even after hot CPI, which is a sign that investors are treating them as a safe haven again.
Why? Because the fear isn't just about inflation anymore. It's about credit risk—the risk that companies that borrowed heavily to fund AI projects might struggle to repay. When that worry grows, investors flee riskier assets and pile into the safest thing they can find: US government bonds. That's why yields fell despite the inflation data.
Credit spreads widening is another tell. When spreads widen, it means investors are demanding higher compensation for holding corporate debt. That's a classic sign of rising anxiety about corporate health. If AI-related companies start to see their borrowing costs rise, it could put further pressure on their stocks.
What does this mean for investors?
For everyday investors, this shift is a reminder that the AI trade isn't a one-way bet. While AI has enormous long-term potential, the companies building the infrastructure are taking on significant debt. If that debt becomes harder to service—because of higher interest rates or disappointing revenue—the stocks could keep falling.
It also highlights the importance of diversification. If bonds are once again acting as a hedge against stock market turmoil, having some allocation to Treasuries or bond funds could help cushion your portfolio during periods of volatility. That's a lesson many investors relearned the hard way in 2022, when bonds and stocks fell together.
But it's not all doom and gloom. The fact that Treasuries are rallying suggests that investors still see the US government as a safe haven, and that the broader economy isn't in immediate danger. The widening credit spreads are a warning sign, but not necessarily a signal of an imminent crisis.
What to watch next
Investors will be watching several things in the coming weeks. First, how AI companies report their earnings—especially any updates on data center spending and revenue growth. Second, whether credit spreads continue to widen, which would indicate growing stress in corporate debt markets. Third, any signals from the Federal Reserve about the path of interest rates, given the sticky inflation.
Also keep an eye on foreign selling in markets like India, which has hit record levels as global investors adjust to higher US rates. And Berkshire Hathaway's recent move to add to its stake in Bending Spoons while chip stocks slide shows that some value investors are finding opportunities outside the AI hype.
For now, the key takeaway is that the market is in a period of recalibration. The easy money in AI may be over, and investors are demanding more proof that the spending will pay off. That's a healthy process, even if it's uncomfortable for those holding AI stocks.
As always, it's important to remember that markets move in cycles. What looks like a setback today could be a buying opportunity tomorrow—or a sign of deeper problems. The best approach is to stay informed, keep a diversified portfolio, and avoid making impulsive decisions based on short-term market moves.
