Japanese authorities intervened in the currency market on Thursday to address the yen's rapid depreciation, which saw the currency fall to the upper 160 range against the U.S. dollar, according to government sources [1]. This marks Japan's first market intervention in one year and ten months [1]. Following the intervention, the yen surged nearly 5 yen to the 155 zone against the dollar within hours [1].
Prior to the intervention, the yen had weakened to 160.72 in Tokyo trading, its lowest level since July 2024, amid ongoing uncertainty related to the Middle East crisis [1]. The dollar continued to strengthen due to its status as a safe-haven asset and expectations that the interest rate differential between the United States and Japan would remain wide, as both the U.S. Federal Reserve and the Bank of Japan left their policy rates unchanged earlier in the week [1].
Finance Minister Satsuki Katayama and the vice finance minister for international affairs had both issued warnings of "decisive action" to halt the yen's slide, with Katayama stating, "The time for decisive action, which I have previously mentioned, is finally getting closer" [1]. Atsushi Mimura, Japan's top currency diplomat, declined to comment on the intervention but referred to his warning against speculative movements as "the final evacuation advisory" [1].
Japan's last intervention in the currency market occurred in July 2024, when authorities spent a total of 5.53 trillion yen ($35 billion) to support the currency after it had weakened to a 38-year low near the 162 yen line against the dollar [1].
CONCLUSION
Japan's intervention in the currency market reflects heightened concern over the yen's rapid depreciation and ongoing market volatility. The decisive action, following strong official warnings, led to a sharp appreciation of the yen and signals the government's readiness to act against speculative movements. Market participants are likely to remain alert for further interventions or policy shifts.
