ECB's Nagel Criticizes U.S. for Uncoordinated Use of Euros in Yen Intervention
nashnova research
Bundesbank President Nagel publicly rebuked the US at the G20 for selling euros to prop up the yen without consulting Europe first — this signals a rare crack in transatlantic FX-policy coordination.
What exactly did Nagel say?
Speaking at the G20 finance ministers' meeting in Asheville, Nagel said the US joined a yen-support intervention without any prior coordination or consultation with European partners.
His words: "Advance coordination and consultation is desirable — and that was the usual practice in the past." He added that the issue was formally raised at the meeting.
This means → Europe chose to air the dispute in a multilateral forum, not just behind closed doors.
Why was this intervention unusual?
Japan intervened in FX markets in late July to support the yen. US Treasury Secretary Scott Bessent confirmed in early August that the US took part, citing "disorderly" yen moves.
The key fact: reports indicate the US used euros, not dollars, to carry out its side of the intervention — breaking long-standing convention in what was an unprecedented move.
In plain terms = the US used someone else's currency to intervene in the market and never told the currency's owner — that is the core of Europe's complaint.
How rare is this kind of surprise?
The last time the US and Japan jointly intervened on the yen was in 2011, when the G7 coordinated to curb excessive yen strength — with full advance consultation.
This reflects a coordination norm that held for over a decade and has now been visibly broken for the first time.
Nagel was explicit about the future: "If such measures are taken again, I expect prior mutual coordination" — diplomatic language, but also a clear red line.
What does this mean for markets?
This means → the trust foundation for transatlantic FX policy has cracked; Europe's willingness to cooperate in any future joint intervention may be diminished.
In plain terms = if major economies intervene in currencies without even a phone call, markets cannot gauge how much firepower the next intervention will carry or how long it will hold.
Near-term, the episode adds an uncertainty premium to the euro in similar scenarios — because the market now knows the euro can be "borrowed" without warning.
