US stock futures are experiencing declines as markets react to multiple factors, including newly imposed tariffs by Trump, the upcoming Federal Reserve meeting, and falling oil prices due to increased output by OPEC+. After setting a record with the longest winning streak in 20 years, stocks are poised to open lower, with investors bracing for potential impacts on trade and economic policy. Key indices such as the Dow Jones, S&P 500, and Nasdaq are all showing negative premarket trends, reflecting concerns about economic indicators and trade negotiations. Asian currencies have risen slightly against a weaker dollar, but overall market sentiment remains cautious ahead of significant economic updates.
