Japan’s Finance Ministry confirmed that it carried out coordinated yen-buying intervention with the United States on Friday to counter what it described as excessive volatility and disorderly movements in the foreign exchange market. Katayama emphasized that Japan will continue to closely watch foreign exchange developments and will not hesitate to take additional measures if market conditions become increasingly unstable. Currency intervention typically involves a central bank or finance ministry buying or selling its own currency to reduce excessive price swings. Market participants will now closely monitor whether the coordinated intervention succeeds in slowing the yen’s recent volatility. With Japan signaling its readiness to intervene again if necessary, traders are expected to remain cautious as authorities seek to prevent further disorderly movements in the yen while preserving confidence in the foreign exchange market.
