The U.S. dollar experienced a weakening trend following the Supreme Court's decision to strike down most Trump-era tariffs, which initially boosted global growth sentiment.

However, gains were tempered by rising geopolitical tensions with Iran and ongoing uncertainty surrounding temporary levies and potential litigation. The dollar's decline was noted against currencies like the euro and Japanese yen.

President Trump has indicated plans to implement alternative tariff measures, including a temporary 15% levy on imports, which has created market debate regarding its potential impact on inflation, Federal Reserve policy, and the risk of de-dollarization. Further complicating the landscape, the European Parliament postponed a vote on a trade deal with the U.S. due to the new import tax.

Traders are also closely monitoring nuclear talks between Iran and the U.S., adding to the cautious market environment.
