Tokyo stepped into the currency markets with a hefty yen-buying operation, estimated around ¥8.45 trillion or $52.8 billion, making it potentially the largest single-day intervention ever. This move aimed to halt the yen's rapid slide toward four-decade lows against the US dollar.
The intervention unfolded during New York trading hours, pushing the yen up by nearly 3%. USD/JPY plunged from near 164 down to below 158. Yet, the Bank of Japan's decision to keep interest rates steady at 1% cooled the rally, letting the dollar bounce back above 160 before settling near 159.
Behind the Scenes and Global Ripple Effects
Japanese officials, including Finance Minister Satsuki Katayama and top currency official Atsushi Mimura, refrained from confirming the intervention outright. However, Mimura hinted at US support that extends beyond mere words, suggesting possible rate checks an indication of behind-the-scenes coordination. US Treasury Secretary Scott Bessent echoed the yen's undervaluation concerns, fueling speculation about Washington’s tacit approval.
Meanwhile, South Korea joined the fray, selling dollars to prop up its won, which surged almost 2% to a nine-month high before retreating. This regional currency activity coincided with rising import costs driven by elevated oil prices amid Middle East tensions, further pressuring Asian currencies.
The Bank of Japan remains cautious, with only one board member favoring a rate hike to 1.25%. Markets now watch Governor Kazuo Ueda’s future guidance closely as the yen’s trajectory hinges on potential changes in Japan’s monetary policy stance.
