USD/JPY Intervention Alert: Yen Surges on BoJ Action Speculation

USD/JPY experienced a dramatic reversal, plummeting from 155.80 to 153.20 in minutes amid strong suspicions of Bank of Japan intervention. The sharp 260-pip decline was accompanied by unusual trading patterns, including massive volume spikes and one-way selling pressure characteristic of official action. Japanese authorities have intensified verbal warnings about excessive yen weakness, with the currency having depreciated over 8% against the dollar year-to-date. The suspected intervention comes as imported inflation pressures mount and public dissatisfaction with weak yen policies grows. EUR/JPY and GBP/JPY also fell sharply, down 1.5% and 1.7% respectively, indicating broad yen strength. Market participants report difficulty executing trades during the volatile period, with spreads widening significantly. Technical damage appears substantial, with USD/JPY breaking below the 154.00 support and 50-day moving average at 153.75, potentially opening the path to 150.00 psychological support.
