Trump Tariffs, Fed Outlook Shift U.S. Markets

U.S. stock index futures dipped after Nvidia briefly reached a $4 trillion valuation, as investors monitored upcoming economic data and U.S. trade policy moves. President Trump imposed a new 50% tariff on copper and threatened similar measures against Brazilian exports, affecting U.S.-listed Brazilian companies. Hopes for trade breakthroughs with India and the EU remain uncertain as nations await official U.S. statements. The Federal Reserve kept interest rates steady in June, with minutes showing most officials expect rate cuts later in the year, though concerns linger over the inflationary effects of new tariffs. A September rate cut is now considered more likely, but the Fed remains cautious amid competing pressures from the White House and economic risks. Market sentiment is shaped by both tariff developments and expectations for future monetary policy.
