U.S. stock markets experienced a significant downturn, with the Dow Jones plunging nearly 900 points, marking the worst day for Wall Street in three months. The declines were largely attributed to escalating tariff threats from the Trump administration regarding Greenland, leading to widespread panic among investors. The S&P 500 and Nasdaq also faced notable drops, with the Nasdaq falling over 2%. This turmoil has led to concerns about economic growth, prompting a flight to safer assets such as gold and silver, which reached record highs. Futures markets showed some stabilization following the selloff, but overall sentiment remains cautious as traders grapple with the uncertainty surrounding trade relations.
