币界网报道：The U.S. dollar rebounded on Tuesday as comments from former President Donald Trump injected fresh uncertainty into financial markets. Trump suggested he might impose tariffs on all imports if re-elected, sparking concerns about potential trade wars and economic disruptions. The dollar index, which measures the greenback against a basket of major currencies, rose 0.3% to 104.50, recovering from earlier losses. Analysts noted that Trump's remarks reignited fears of protectionist policies, prompting investors to seek refuge in the dollar as a safe-haven asset. Meanwhile, global stocks wavered, with the S&P 500 and Nasdaq Composite dipping slightly amid the renewed trade tensions. Treasury yields also edged higher as markets weighed the implications of potential policy shifts under a second Trump administration. The euro and yen weakened against the dollar, reflecting broader risk aversion. Economists warn that a return to aggressive trade measures could disrupt supply chains and fuel inflation, complicating central banks' efforts to stabilize economies. Market participants are closely monitoring political developments for further clues on future trade and monetary policies.
