FX.co ★ Yen Slips as Dollar Rebounds

The Japanese yen weakened to around 155 per dollar on Tuesday, erasing gains from the previous session as the greenback held firm despite persistent uncertainty over US trade policy. Over the weekend, US President Donald Trump threatened to raise global tariffs from 10% to 15% after the Supreme Court struck down his reciprocal tariff measures, and he warned of steeper duties on countries that “play games” with existing trade agreements. In response, Tokyo urged Washington to ensure the ruling would not hurt Japanese companies and reaffirmed its commitment to the bilateral trade deal with the United States.

At the same time, Japanese media reported that US authorities had proactively carried out foreign exchange rate checks last month to support the yen and stood ready to coordinate intervention if requested by Japan. The reports said US Treasury Secretary Scott Bessent led the effort, reflecting concerns that political uncertainty ahead of Japan’s general election could unsettle financial markets.
