Japan’s Yen Crisis: How Tokyo, the BOJ, and Washington Are Joining Forces to Stop the Currency Collapse

This analysis examines Japan’s escalating efforts to defend the yen against a combination of global oil shocks, widening interest-rate differentials between Japan and the United States, and intensifying speculative currency trading. Tokyo has moved beyond traditional market intervention, coordinating closely with the Bank of Japan under Governor Kazuo Ueda’s increasingly hawkish leadership, while simultaneously seeking tacit support from Washington ahead of U.S. Treasury Secretary Scott Bessent’s upcoming visit. The report traces how Japan’s currency strategy has evolved from reactive, episodic interventions into a broader geopolitical and monetary-policy campaign, and assesses whether this approach can deliver lasting yen stability or merely buy time against structural pressures.
