Kospi Falls 7% as Global Tech Rout Deepens

The context

The sell-off caps a multi-day stretch of pressure on technology shares worldwide. The rout deepened Thursday and carried into Friday's Asian trading session, where the Kospi, heavily weighted toward chipmakers and tech firms, absorbed one of the sharpest declines.

The AI spending boom has been the dominant investment theme in markets for the past three years, drawing enormous capital into chipmakers, data infrastructure and the companies building AI systems. Much of that expansion has been financed with debt. What has shifted, per Axios, is the willingness of Wall Street to keep extending that credit: financiers who once backed the build-out are now questioning whether the returns will justify the borrowing, and banks are stepping back from funding it. The hotter U.S. inflation reading added a second pressure point, reviving concern about where interest rates head from here.

Why it matters

A multi-day global tech rout touches American investors directly through retirement accounts heavy with technology holdings. The episode also tests the investment narrative that has powered markets for three years: that AI spending will eventually pay for itself. If banks continue retreating from AI debt, the companies driving the build-out could face tighter financing conditions. And the inflation data that helped trigger the sell-off feeds into the Federal Reserve's rate deliberations, linking the market turmoil to the broader path of U.S. monetary policy.

What’s next

Watch whether the sell-off extends into subsequent trading sessions or stabilizes, and whether U.S. markets follow Asia's declines. Key open questions include how far banks pull back from AI-related lending and whether major AI spenders adjust their investment plans in response. The Federal Reserve's reaction to the hotter inflation data remains a central variable for markets; the material does not indicate when the Fed next acts.
