Japan’s currency experienced its most dramatic single-day surge in more than three years on Thursday, climbing 3% after government officials issued stern warnings about possible intervention to support the struggling yen.
By 1250 GMT, the dollar had dropped to 155.94 yen as Japan’s currency made significant gains. The American dollar was heading toward its steepest daily decline since December 2022, when it plummeted 3.8% in one trading session.
Finance Minister Satsuki Katayama delivered her most forceful indication yet that currency intervention might be approaching, stating earlier Thursday that the moment for “decisive action” in financial markets was drawing near.
Market analysts noted that the sharp decline, which began around 1026 GMT, showed characteristics typical of government purchasing activity. However, previous instances of official intervention have typically resulted in even more rapid dollar-to-yen movements.
Societe Generale currency strategist Kenneth Broux weighed in on whether Bank of Japan intervention might be driving the yen’s movement, saying: “It certainly looks like it and short covering.”
“The ‘final warning’ comment has rattled a few accounts for sure,” he added.
Recent positioning data reveals that investors currently maintain their largest short position against the yen since July 2024, betting the currency will continue to weaken.
Officials at Japan’s finance ministry foreign exchange division were unavailable for immediate response.
The last time Tokyo stepped into currency markets was in July 2024, when the yen had weakened to nearly 162 against the dollar.
Market participants have remained cautious about intervention possibilities ever since the New York Federal Reserve reportedly conducted a rate check in January, which traders interpreted as at least implicit U.S. support for yen strengthening.
Bank of America senior FX strategist Kamal Sharma noted: “There’s been no confirmation from the BOJ but there is a heightened sense of urgency this morning on the willingness to intervene.”
“I suspect the market was poised for a move once we got over 160 yesterday and now we are back down near 157. In real terms the yen is trading near record lows,” Sharma explained.
The yen has weakened against the dollar amid ongoing Middle East tensions involving the U.S. and Israel’s conflict with Iran, with Prime Minister Sanae Takaichi’s government emphasizing the economic consequences.
Japan’s weakened currency has made imported fuel costs even more expensive for the nation.
The Bank of Japan maintained current interest rates this week, though three of its nine board members pushed for rate increases, reflecting concerns about inflation pressures stemming from the regional conflict.
