Japan’s Katayama Warns “Don’t Put Your Smartphones Down” as Intervention Nears

Japan’s finance minister Satsuki Katayama warned that the time for “bold steps” to curb Yen weakness was “nearing,” and urged officials to stay vigilant over the Golden Week holiday. The verbal intervention succeeded immediately: USD/JPY briefly spiked to 160.71 (its highest since mid‑2024) but quickly retreated below the 160 level. The piece highlights that rhetoric alone can deter speculative pressure around the 160 “red line,” though sustained Yen strength will depend on whether warnings are followed by actual intervention amid widening rate differentials and rising energy costs. Market sensitivity around the 160 threshold remains high, making future moves dependent on official action and liquidity conditions.
