The US dollar retreated Monday amid renewed uncertainty over President Donald Trump's trade tariffs following a Supreme Court ruling that his previous tariffs exceeded presidential authority, with markets also reacting to ongoing nuclear negotiations between the US and Iran as the greenback fell against the euro and sterling. At 04:15 ET (09:15 GMT), the Dollar Index, which tracks the greenback against a basket of six other currencies, traded 0.3% lower to 97.487, having last week recorded a weekly gain of around 1%, its strongest performance in more than four months. The Supreme Court found on Friday that Trump's sweeping tariffs exceeded his authority, prompting the US president to lash out at the court and impose a blanket 15% levy on imports, creating additional confusion in global trade relationships. Markets remain cautious as Trump's replacement levies run for 150 days and it remains unclear if the US owes importers refunds on duties already paid, with analysts noting this could result in years of litigation while Trump seeks more permanent solutions. Beyond trade tensions, traders are monitoring a US military buildup in the Middle East as it pressures Iran to drop pursuit of nuclear weapons, with the US and Iran expected to hold more talks later in the week.

Subscribe to InvestingPro for more foreign exchange analysis Trade uncertainty hits greenback The Supreme Court found on Friday that Trump’s sweeping tariffs exceeded his authority, and the U.S. president responded by lashing out at the court and imposing a blanket 15% levy on imports. “This means that the likes of China and Brazil could get lower tariff rates, but countries such as the U.K. and Australia would lose the advantage of their 10% negotiated deals,” said analysts at ING, in a note. “Needless to say, many are now reviewing their trade deals with the U.S., the most important of which is probably the EU.” Trump’s replacement levies run for 150 days and it is not clear if the U.S. owes importers refunds on duties already paid, with the Supreme Court making no ruling on that issue.
