US-Japan Currency Intervention Marks Shift Away from Multilateral Coordination

The US-Japan currency intervention has sparked questions about the future of international coordination on global exchange rates.

Last week's joint operation between Washington and Tokyo to support the Japanese yen was notable for its lack of broader participation from other G7 economies.

The intervention aimed to strengthen the yen, which had weakened to multi-decade lows against the US dollar. US Treasury Secretary Scott Bessent and Japanese Finance Minister Satsuki Katayama defended the operation, citing concerns over the US Treasury market.

One key factor behind US involvement was reportedly the need to prevent a large unilateral intervention by Japan that could have disrupted volatile bond markets.
