US dollar weakens sharply against Japanese yen after market interventions

The US dollar experienced a sharp decline against the Japanese yen on Monday after both the United States and Japan officially confirmed they had intervened in currency markets. This intervention aimed to curb the dollar's rapid ascent, which had seen it trading above 163 yen, reaching levels not seen in 40 years.

Prior to the official announcement, the dollar had already fallen below 160 yen, a level regulators were suspected of influencing. Following the confirmation of coordinated market action, the dollar dropped further, reaching nearly 155.20 yen early Monday. By late afternoon Tokyo time, it was trading around 156.75 yen.

Despite the yen's weakness attracting tourists, it has become a source of frustration for Tokyo due to rising import costs, particularly for oil, which exacerbates the cost of living. Japanese Prime Minister Sanae Takaichi's administration faces pressure to address these concerns.

Factors such as the significant interest rate gap between the US and Japan have driven investors to sell yen and buy dollars for higher yields. Both the Bank of Japan and the Federal Reserve maintained their interest rates last week, keeping this gap intact. The confirmation of intervention, including statements from US President Donald Trump and Japanese Finance Minister Satsuki Katayama, marks a rare overt acknowledgment of such actions, with Katayama stating, "We will not hesitate to conduct further joint intervention."
