U.S. Stocks Slide as Global Bond Selloff Sends Yields to Decade Highs

U.S. stocks fell on Monday as a worldwide bond selloff pushed long-term borrowing costs to their highest levels in years. The decline in equities came as investors shifted money away from riskier assets, with the yield on the benchmark 10-year Treasury note reaching a peak not seen in over a decade. Higher bond yields make government debt more attractive compared to stocks, reducing the appeal of shares in technology and other growth companies. This pressure weighed heavily on major indexes, which closed the session lower across the board. The market moves also unfolded as a temporary truce between Iran and its regional adversaries expired, adding a layer of geopolitical uncertainty to the trading day. While no immediate escalation was reported, the lapse kept investors cautious about the potential for supply disruptions and broader instability. Analysts noted that the combination of rising yields and geopolitical friction could keep markets volatile in the near term. However, they emphasized that the primary driver of the selloff remained the bond market, where investors are demanding higher returns to hold long-term debt.
