On Thursday, the U.S. dollar experienced a significant decline against the Japanese yen, dropping by as much as 3% to 155.5 yen. This decline followed reports that Japanese authorities intervened in foreign exchange markets to bolster the yen, which had reached its weakest level against the dollar since July 2024. Japanese Finance Minister Satsuki Katayama indicated that the time for decisive action was nearing, suggesting further intervention could be on the horizon. The dollar index also fell by 0.70% to 98.17, snapping a two-day streak of gains. Meanwhile, Brent crude prices retreated by 3.34% to $114.09 per barrel as geopolitical tensions, particularly the ongoing conflict in the Middle East, continued to influence market dynamics. The Federal Reserve and the European Central Bank both maintained their interest rates, contributing to the dollar's weakened position against other currencies, including a 1.14% drop against the Swiss franc.
