The Japanese yen strengthened to a nearly one-month high against the dollar amid chatter that authorities could again intervene in foreign-exchange markets. Traders are monitoring for signs of official action to support the currency, which has faced pressure from divergent monetary policies between Japan and the United States. The yen’s gain reflects growing speculation that Japanese officials may step in to prevent further depreciation, especially as the dollar remains strong amid elevated U.S. interest rates.

Market participants are closely watching statements from Japanese financial authorities for any indication of intervention intent.
