US euro sale to prop up yen blindsided ECB - Financial Times

According to a Financial Times report, the U.S. recently sold euros in the foreign exchange market to help support the yen, a move that took the European Central Bank (ECB) by surprise. The intervention appears to have been executed without prior coordination with the ECB, even though the euro was the funding currency for the sale. Such operations are typically arranged jointly among major central banks to maximize impact and minimize market confusion.

The episode is notable because it signals Washington’s growing discomfort with yen weakness, which has been driven by wide interest-rate differentials between Japan and the U.S. For markets, an uncoordinated intervention raises questions about official sector tolerance for further currency moves. Traders and analysts will be watching whether the ECB responds in kind, and whether this action marks a broader shift in U.S. policy toward active FX management. The key takeaway is that the dollar-yen and euro-dollar exchange rates are no longer solely a function of monetary policy divergence; they are now subject to the unpredictable influence of direct official selling.
