After a sharp yen rally, Japanese authorities declined to confirm whether they intervened in overnight FX trading but signalled overseas assistance, including from the United States. Finance Minister Satsuki Katayama avoided confirming intervention, saying authorities will "remain highly vigilant and respond appropriately as the situation requires."
