This market will resolve to "Yes" if the United States government announces that it has intervened in the foreign exchange market to support the Japanese yen between market creation and the listed date, 11:59 PM ET. Otherwise, this market will resolve to "No". A qualifying announcement must establish that (i) the United States purchased Japanese yen in the foreign exchange market and (ii) the purchase was undertaken as an exchange-rate intervention, whether stated explicitly or clearly established through context. The intervention may be unilateral or coordinated with other governments, but the United States must participate directly. Any qualifying announcement made within this market's time frame will count, provided the underlying yen purchase occurred after July 31, 2026. Statements of concern, readiness, or intent to intervene; swap lines or other currency arrangements absent a qualifying yen purchase; and intervention by other governments without US participation will not qualify. A qualifying announcement must be made through official channels, by an individual acting in an official capacity. Statements made incidentally or informally in a context not intended for official communication do not qualify. Resolution will be based on official statements from the US Treasury, Federal Reserve, White House, or their official representatives acting in an official capacity.**Recent yen weakness driven by wide U.S.-Japan interest rate differentials and domestic fiscal pressures has kept traders alert for further coordinated action.** Following the rare late-July joint U.S.-Japan intervention that lifted the yen from 40-year lows near 164 to the mid-150s, USD/JPY has traded back toward 158-160 as of early September, with a sharp yen rally on September 2 prompting fresh speculation of official checks or intervention. Japan’s Ministry of Finance has already deployed tens of billions this year, while U.S. participation—via euro sales and signaling—aimed to curb disorderly moves and limit potential Japanese Treasury selling. Key near-term catalysts include the Bank of Japan’s September 17-18 policy meeting and any renewed pressure on the yen from carry-trade unwinds or energy-price volatility. Market-implied odds reflect ongoing sensitivity to these levels, with authorities having signaled willingness for additional steps if volatility reemerges.
