Dollar surges against the euro after US court blocks Trump's tariffs

On Thursday, the dollar reversed some of those moves and rose 0.72% against the yen to 145.86 and 0.63% against the Swiss franc to 0.8326.

The US dollar rallied on Thursday in a knee-jerk reaction to a court blocking President Donald Trump from imposing his import tariffs on other countries, providing some relief for the currency that has struggled this year due to trade uncertainty.

The Manhattan-based Court of International Trade said the US Constitution gives Congress exclusive authority to regulate commerce with other countries that is not overridden by the president's emergency powers to safeguard the US economy.
