$200 BILLION VANISHED FROM U.S. STOCKS IN JUST 30 MINUTES.

Wall Street was hit by a brutal wave of selling as stocks flashed red across the board.

Higher long-term yields can tighten financial conditions and make equities less attractive, especially expensive growth and technology stocks.

When bond yields move this aggressively, markets pay attention fast.

The question now: is this just a sharp shakeout—or the beginning of something much bigger?
