Tokyo – Japanese authorities are signaling a potential shift towards allowing further depreciation of the yen, as the currency continues to fall to multi-year lows amid a widening interest rate differential with the United States and escalating geopolitical concerns in the Middle East. Atsushi Katayama, a top currency diplomat, stated Friday that Japan is prepared to take “all necessary steps” to address excessive volatility in the foreign exchange market, a statement widely interpreted as a warning against speculative trading.
The yen recently hit a latest low against the Singapore dollar, a move coinciding with a surge in oil prices triggered by the ongoing crisis in the Middle East, adding further pressure on the Japanese currency. The Nikkei Asia reported the yen weakened to 159 per dollar despite a reserve release intended to stabilize prices. This depreciation has prompted increased scrutiny from international partners, including the United States.
Finance Minister Satsuki Katayama recently affirmed that Prime Minister Sanae Takaichi did not specifically emphasize the benefits of a weaker yen, a clarification issued in February following earlier remarks that appeared to suggest a tolerance for currency weakness. This attempt to recalibrate messaging comes as Japanese officials navigate a delicate balance between supporting export-oriented industries and mitigating the inflationary impact of a weaker yen.
Concerns over the yen’s decline were also discussed between Katayama and U.S. Treasury Secretary Scott Bessent, with both officials expressing shared anxieties over the “one-sided depreciation,” according to statements released in January. Japan’s top currency diplomat, Atushi Mimura, traveling with Katayama, indicated a commitment to coordinate on foreign exchange rates as needed. Though, historically, Japan has been reluctant to intervene directly in the foreign exchange market due to potential diplomatic repercussions with its G7 partners.
The divergence in monetary policy between Japan and the U.S. Remains a key driver of the yen’s weakness. Even as the Federal Reserve has maintained elevated interest rates to combat inflation, Japan has only recently begun to move away from its long-standing negative interest rate regime. This gap has encouraged carry trades, where investors borrow yen at low interest rates to invest in higher-yielding assets elsewhere, further exacerbating the downward pressure on the currency.
Katayama emphasized that while exchange rates should ideally reflect economic fundamentals, recent movements have been driven by speculative behavior. He also stressed that extreme fluctuations create uncertainty for businesses and complicate long-term planning for Japanese corporations. The Ministry of Finance is closely monitoring the situation and maintaining communication with international counterparts to ensure market stability.
