Japan Intervenes to Prop Up Yen for First Time Since 2024, Sending USD/JPY Down 3%
The Bank of Japan's dramatic return to the currency markets signals a new phase in its battle against a weakening yen, with significant implications for global financial stability.
Japan's central bank intervened in the foreign exchange market on Thursday for the first time since 2024, buying the yen to pull it back from a multi-decade low against the dollar. The move sent the USD/JPY pair plummeting by as much as 3%, its largest one-day drop since December 2022, after the currency had earlier touched its weakest point since July 2024.
"The timing to take 'decisive action' in the market was nearing," Japanese Finance Minister Satsuki Katayama said earlier on Thursday, in her strongest signal yet of potential currency intervention. Top currency diplomat Atsushi Mimura echoed this sentiment, stating that "extremely speculative" moves were increasing and that it was their "final evacuation warning to markets."
The intervention, confirmed by a government source cited by Nikkei, saw the dollar fall sharply from a high above 160 yen to as low as 155.01. The U.S. currency was last trading at 156.665 yen, down 2.3% on the day. The aggressive move comes after weeks of verbal warnings from Japanese officials failed to stem the yen's slide, which has been driven by the wide interest rate differential between the ultra-low rates in Japan and rising rates in the U.S.
This direct intervention marks a major escalation in Japan's efforts to combat yen weakness, which has been inflating import costs and squeezing household and corporate budgets. The move raises questions about the sustainability of the Bank of Japan's ultra-loose monetary policy and whether this is a one-off action or the start of a more concerted campaign to support the currency. The focus now shifts to whether the intervention will have a lasting effect and how the U.S. Treasury will react, given that unilateral interventions are often frowned upon.
A Shift in a Multi-Decade Battle
The intervention on April 30th, as reported by Nikkei, marks a significant turning point. For months, the Ministry of Finance has been issuing warnings, but the yen continued its slide. The move to directly buy yen and sell dollars is a tactic not seen since 2024, highlighting the severity of the situation in the eyes of Japanese policymakers. The yen had depreciated by over 10% against the dollar in 2026 alone before the intervention.
The Ripple Effect on Global Markets
The sharp reversal in the USD/JPY has sent ripples across global financial markets. The yen's sudden strength could impact Japanese exporters, who have benefited from a weaker currency. It also puts the spotlight on other central banks and their own currency challenges. The intervention could lead to a period of heightened volatility in currency markets as traders assess the resolve of the Bank of Japan and the potential for further action. The next policy meeting of the Bank of Japan will be closely watched for any changes in its stance, though a specific date for the next meeting was not yet announced.
