The ECB was notified only after euros were sold to fund yen purchases, signaling limited coordination among major central banks.
The European Central Bank was informed of the US-Japan yen intervention only after the trade was executed, highlighting a narrowly coordinated effort. The operation involved selling euros to buy yen, a move that excluded prior ECB input and may fuel uncertainty in currency markets about central bank alignment.
Last week’s intervention marked a rare joint effort by the US and Japan to support the yen, which hit 40-year lows. Both nations indicated further action could follow if needed, underscoring the scale of the intervention and its potential market impact.
The lack of advance ECB involvement may raise questions about future euro positioning, as traders assess the implications of unannounced currency interventions. Markets are now on alert for possible repeat actions, given the historic nature of the move.
