Trump claims US intervened to prop up yen out of friendship for Japan as yen hits near‑40‑year low
Executive summary: Donald Trump claimed the United States intervened in currency markets to support the Japanese yen out of friendship for Japan, citing an unprecedented euro‑sale by the New York Federal Reserve to buy yen while the yen hovered near a 40‑year low. Alleged FX intervention could move currency markets, affect trade balances, and signal rising currency‑policy tensions between the United States and Japan, potentially influencing monetary policy expectations and trade negotiations.
Who is involved: Donald Trump (former US president), the New York Federal Reserve (implied actor), Japanese authorities (implicitly involved), and foreign‑exchange market participants.
Likely next: Market participants will watch for any official confirmation or denial from the Fed and Japanese Ministry of Finance; if confirmed, the yen could experience heightened volatility and prompt diplomatic discussions between Washington and Tokyo.
Donald Trump asserted that the United States intervened in foreign‑exchange markets to support the Japanese yen, citing an unprecedented euro‑sale by the New York Federal Reserve to buy yen while the currency hovered near a 40‑year low. The New York Fed has not publicly confirmed such an operation, and Japanese officials have not commented on any alleged intervention. If true, the move could signal heightened currency‑policy tensions between the United States and Japan and influence market expectations for future FX policy.
