On May 15, 2026, the US stock market faced a sharp decline, with the Dow Jones Industrial Average falling 366 points to close at 49,697, the S&P 500 dropping 0.86% to 7,436, and the Nasdaq Composite sliding 1.25%. This downturn was primarily fueled by renewed inflation fears, as recent US inflation readings exceeded expectations, prompting bond investors to react swiftly. The 10-year Treasury yield surged by 11.3 basis points to 4.57%, raising concerns about rising borrowing costs. The market had been buoyant just a day earlier, reaching record highs, but uncertainty surrounding the Trump-Xi summit in Beijing, particularly regarding the unresolved Taiwan issue and ongoing tensions in the Middle East, dampened investor sentiment. Additionally, the US dollar index climbed to 99.107, further pressuring commodities and multinational earnings. Precious metals also suffered, with gold prices plummeting 2.66% and silver collapsing 8%. Despite the overall market decline, some stocks like Microsoft and Cisco posted gains, indicating a shift in investor focus towards more stable sectors. Looking ahead, market movements will depend on whether Treasury yields stabilize and how geopolitical tensions evolve.
