The stock market experienced significant turmoil as the Dow Jones Industrial Average fell by 800 points, marking its worst day in a month. This dramatic decline came amid rising Treasury yields, which surged past 4.5%, leading to fears of a broader bond market sell-off. Investors are particularly concerned about the implications of a tax bill championed by Trump, causing apprehension over U.S. debt and foreign investment interest. Other major indices, such as the S&P 500 and Nasdaq, also experienced steep declines. Bitcoin reached a record high, partially offsetting the overall negative sentiment in the market, but concerns over fiscal policies and rising yields continue to weigh heavily on investor sentiment, particularly as Asia-Pacific markets brace for similar declines.
