Washington and Tokyo officially acknowledge coordinated FX action, signaling sustained support for the yen amid narrowing rate differentials.
The US Treasury and Japan’s Ministry of Finance confirmed Friday’s joint yen intervention, removing prior ambiguity. Both governments pledged further action if needed, reinforcing a near-term floor under the currency.
The move aligns with Washington’s support for Japan’s efforts to correct what Treasury Secretary Scott Bessent termed a “substantial undervaluation” of the yen. While no immediate BOJ rate hike was announced, the intervention bolsters the narrative of a shrinking US-Japan rate gap, which has pressured the dollar-yen pair.
Traders may view the on-record confirmation as reducing the risk of a rapid retreat toward recent 40-year lows, though sustained yen strength hinges on future BOJ policy moves. Plans to expand the FIMA repo facility suggest a longer-term structural backstop.
