US dollar weakens against safe-haven currencies in rattled markets
The U.S. dollar weakened against safe-haven currencies including the yen and the Swiss franc while the euro strengthened on Wednesday as markets grappled with tit-for-tat measures by major countries in response to U.S. tariffs. President Donald Trump's "reciprocal" tariffs on dozens of countries took effect on Wednesday, including massive 104% duties on Chinese goods. EU countries also approved on Wednesday the bloc's first countermeasures against U.S. tariffs.
