In the early morning of March 19, all three major U.S. stock indexes tumbled sharply, with the Dow falling 1.63%, S&P 500 1.36%, and Nasdaq 1.46%, as risk aversion surged.

The Fed’s hawkish stance and Middle East risks were the main triggers. Expectations of higher rates for longer directly pressured high‑valuation technology and growth stocks. Micron Technology, which had hit record highs, dropped nearly 6% after earnings, weighing on the entire chip sector. Large tech stocks fell broadly, with capital rotating away from risky assets toward cash and defensive sectors.

European markets also declined, with Germany’s DAX, France’s CAC, and the UK’s FTSE 100 all closing lower. Asian stock markets opened lower in early trading. The VIX fear index jumped sharply, signaling a rapid rise in market volatility.

Institutions warn that U.S. stocks have entered a high‑volatility phase. Under dual pressure from geopolitical risks and monetary policy, further short‑term corrections are likely, with a focus on defensive sectors and companies with stable cash flow.
