ECB President Lagarde (Q&A): will not comment on the FX intervention action that has been happening from the US, with respect to EUR selling and JPY purchases. The sale of 0.5bln worth of Euros.

The reported action described, US-side selling of EUR and purchases of JPY, would represent an unusual configuration if confirmed, since coordinated or unilateral dollar-selling intervention by US authorities has historically been rare and typically reserved for episodes of acute dollar strength or disorderly moves, often executed jointly with other central banks. The size referenced is small relative to daily EUR and JPY turnover, which in past intervention episodes has meant the signalling weight outweighs the flow itself: the transmission runs through positioning and the perceived official tolerance for a level, not through the volume transacted. The questions that matter are whether the operation is confirmed and by whom, whether it is coordinated or unilateral, and whether follow-through operations materialise, since single-day, one-off actions have historically faded in effect while repeated, coordinated ones have reset trends. Watch the Federal Reserve and Treasury for acknowledgement or silence, and whether Japanese officials frame yen purchases as their own operation. Lagarde's refusal to engage leaves the ECB formally outside it, which is the usual posture unless euro strength begins to bite on the inflation forecast.
