U.S. financial markets experienced declines in stocks and the dollar amid growing concerns over President Donald Trump's proposed tax-cut bill and its potential impact on the country's fiscal outlook. The S&P 500 ended a six-session winning streak, pressured by rising Treasury yields as investors worried about the expansion of government debt by trillions of dollars if the bill passes. Treasury yields climbed to near their highest levels in 18 months, contributing to the sell-off in both stocks and bonds. The U.S. dollar also weakened, influenced by cautious sentiment regarding the economy and ongoing discussions at the Group of Seven (G-7) meeting, where global leaders considered currency policies amid trade negotiations with the U.S. Market participants remain focused on the implications of the tax legislation and the broader fiscal and trade policies, which have stirred uncertainty about the U.S. economic outlook.
