The U.S. dollar opened higher on March 12 and 13, 2025, as inflation data and tariffs imposed by President Trump drew investor attention. On March 12, the dollar gained against major currencies, including the yen and the euro, with the dollar index rising 0.13% to 103.57. The dollar strengthened to 148.31 yen, reflecting a 0.37% increase. However, on March 13, the dollar faced challenges as concerns about the impact of an escalating global trade war on U.S. inflation and growth emerged. Despite this, the dollar opened slightly higher amid ongoing tensions in trade and key U.S. economic data being closely monitored by investors.
