Euro Surges to Six-Week High as Suspected Japanese Intervention Weakens Dollar

The euro surged to a six-week high against the US dollar on Wednesday after market participants suspected that Japanese authorities had intervened in currency markets. The move pushed EUR/USD above 1.0900 for the first time since early April, as the dollar weakened broadly against major currencies.

The suspected intervention caused a rapid reversal in the dollar's strength, dragging EUR/USD higher as the greenback lost ground across the board. Traders noted that the move was amplified by thin liquidity during the Asian session, typical of intervention events.

When Japan intervenes to sell dollars and buy yen, the dollar weakens against the yen, often spilling over into other major pairs. The euro benefits directly as the dollar's primary counterpart.
