The United States and Japan conducted a coordinated foreign-exchange market intervention on July 31 to curb the rapid depreciation of the yen [1], [2].
This joint action marks a significant shift in monetary cooperation. The move aims to stop excessive volatility that has increased inflation pressures in Japan and threatened to destabilize U.S. financial markets through potential capital outflows [1], [2].
U.S. Treasury Secretary Scott Bentsen and Japanese Finance Minister Satsuki Katayama announced the operation. The intervention is the first joint yen-defense action in 15 years [1], with the previous coordinated effort occurring in March 2011 [1], [3].
Officials sought to prevent a scenario where Japan might dump large amounts of U.S. Treasury securities to fund its own currency stabilization efforts [1], [2]. By coordinating the buy, both nations aimed to signal a unified front to currency speculators.
"This intervention is a signal of the friendship between the United States and Japan," Donald Trump said [1].
Japanese Finance Minister Satsuki Katayama noted the rarity of the event. "Joint action of this kind has not been seen since March 2011," Katayama said [1].
The U.S. Treasury indicated that this may not be a one-time event. "We are keeping the door open for further intervention if needed," Bentsen said [1].
While some reports suggest a longer interval since the last joint action, the official timeline provided by the ministers points to a 15-year gap since the 2011 intervention [1], [3].
“Joint action of this kind has not been seen since March 2011.”
The coordination between the U.S. and Japan suggests that the yen's decline had reached a threshold that threatened global financial stability, specifically regarding the U.S. Treasury market. By acting together, the two powers aim to reduce the cost of intervention and amplify the psychological impact on traders, signaling that they will not allow currency volatility to jeopardize their broader economic partnership.
