US Treasury pivots to euro-yen sales in rare yen support operation

Japan confirmed it conducted joint yen-buying intervention with the U.S. Treasury on Friday, but reports indicate the operation utilized euro-yen crosses rather than standard dollar-yen transactions. Market participants note that this tactical choice prevents the market from interpreting the move as a sign of American desire for a softer dollar. For the Federal Reserve, currently grappling with inflation above its target, an aggressively weak dollar would create unnecessary pressure to maintain higher interest rates.

Data suggests Japan may have deployed approximately $36.58 billion during Friday’s intervention. While the yen has climbed from 40-year lows near 164 to trade around 157 per dollar, the long-term efficacy of these measures remains under scrutiny. The U.S. holds roughly €26 billion available for such operations, a limited reserve that MUFG analysts believe restricts the potential impact on the euro. While the European Central Bank has declined to comment on the specific trades, market observers are now watching for any signs of broader currency accords, noting that direct participation from the ECB would represent a high-impact shift in global monetary cooperation.
