The yen exchange rate is nearing the critical 160 level against the US dollar, prompting heightened warnings of potential intervention from Japanese authorities. Markets are holding their breath for the latest remarks from Bank of Japan Governor Kazuo Ueda following the central bank's interest rate decision.
Japan's Finance Minister, Satsuki Katayama, stated at a press conference after a cabinet meeting on Thursday that authorities "maintain a high level of vigilance at all times" and are "fully prepared to respond comprehensively" to currency fluctuations. She emphasized that the impact of exchange rate movements on people's lives is being given full consideration. The yen had previously touched 159.90, its lowest level since July 2024, but stabilized around 159.80 following Katayama's comments.
Subsequently, the Bank of Japan announced its decision to keep the benchmark interest rate unchanged, aligning with broad market expectations. Following the announcement, the yen edged up 0.1% to 159.65, while the Nikkei 225 index fell 2.7%, tracking broader risk-off sentiment in Asia. Multiple analysts pointed out that the tone of Governor Kazuo Ueda's upcoming press conference will be crucial in determining whether the yen can defend the key psychological barrier of 160.
The current phase of yen weakness has been triggered by a combination of negative factors. Federal Reserve Chair Jerome Powell struck a hawkish tone, indicating a need to see more definitive signs of declining inflation before considering rate cuts. Concurrently, reciprocal attacks on key energy infrastructure by Iran and Israel have pushed oil prices higher. The combination of rising oil prices and persistent yen depreciation is intensifying concerns about Japan potentially sliding into stagflation.
Intervention warnings are escalating, with Katayama emphasizing readiness to act. During her press conference, Katayama noted that Thursday presented a day where "speculators might find it easier to exert force," citing the confluence of the BoJ Governor's press conference, a Japan-US leaders' meeting, and the evolving situation in the Middle East as factors creating greater potential for market volatility.
According to Bloomberg reports, Japanese authorities intervened multiple times in 2024, buying yen to support the currency when it breached the 160 level. Katayama's firm stance is being interpreted by markets as a clear signal that authorities remain on high alert. Following the January BoJ meeting, coordinated actions by US and Japanese authorities triggered a strong rebound in the yen, which ultimately appreciated by approximately 7 yen against the dollar.
The Bank of Japan's decision to hold rates steady, with its statement focusing more on the inflationary impact of the Middle East situation and oil prices rather than significant negative shocks to growth prospects, resulted in little overall change to policy guidance. Overnight index swap data indicates traders currently see about a 58% probability of a rate hike in April.
Yujiro Goto, Chief FX Strategist at Nomura Securities, noted that while the statement added descriptions concerning the Middle East and oil prices, it was generally in line with expectations. "The main scenario remains unchanged, and there's no need to hastily adjust the outlook now," he said. Goto pointed out that Katayama's hawkish verbal intervention has temporarily dampened market momentum to test higher levels for USD/JPY. He characterized the meeting outcome as overall neutral but warned that "if Kazuo Ueda's wording leans dovish, a resurgence of yen selling pressure cannot be ruled out."
Hiroshi Namioka, Chief Strategist at T&D Asset Management, believes the BoJ's comments regarding oil's impact on core CPI suggest that even cost-push inflation "leaves room for a possible April hike." He also noted that Kazuo Ueda's press conference "holds the potential to be more hawkish than expected," which would likely strengthen the yen and put pressure on equities.
Eugenia Fabon Victorino, Head of Asia Strategy at SEB, observed that the BoJ's statement focused its description of war risks more on inflationary impacts than growth shocks, resulting in limited substantive changes to policy guidance. She added that if Kazuo Ueda's remarks appear slightly dovish, USD/JPY could likely find buying support.
The 160 level is seen as the most critical psychological barrier for USD/JPY at present, with markets still showing some restraint around this level. Rinto Maruyama, FX and Rates Strategist at SMBC Nikko Securities, stated that a move to 160 for USD/JPY "is not impossible," but he expects it would be difficult for the pair to sustain levels significantly above 160 for an extended period. Due to the strength of Katayama's verbal intervention, traders might be reluctant to hold long positions ahead of a three-day holiday. He also warned that if authorities resort only to verbal intervention after a breach of 160, "USD/JPY would highly likely continue its ascent," though the actual probability of physical intervention currently remains low, making it "difficult for investors to feel truly at ease."
Victorino also pointed out that the current rise in the exchange rate essentially reflects a deterioration in Japan's terms of trade rather than specific speculative attacks targeting the yen.
The simultaneous progression of rising oil prices and yen depreciation is drawing increased attention to Japan's potential stagflation risks. Analysts note that if Japan faces a scenario of economic stagnation coupled with inflation, it could prompt the government to increase fiscal spending, thereby complicating the path for the Bank of Japan's monetary policy tightening.
