Japan's Ministry of Finance stepped back into the FX market on Oct. 21, marking its second intervention this month and the second of the year, in a bid to stem a sharp selloff in the yen. USD/JPY had climbed to 151.94, the highest level in 32 years, before dropping quickly to 144.50 after the suspected action—a near 600-pip intraday swing. The move is widely seen as a direct response to persistent yen weakness tied to the Bank of Japan's commitment to negative rates and its yield curve control (YCC) policy. While officials stopped short of a formal confirmation, MoF comments pointed to "stealth intervention" and reiterated zero tolerance for "excessive volatility."
