The US Treasury bought yen on Friday alongside Japan, according to the Financial Times, marking Washington's first yen-buying intervention with Tokyo in over a decade. The Fed's New York branch sold euros for yen on the Treasury's behalf, and a Treasury notepad showed plans to buy $5-10 billion in yen.
Coordinated US and Japanese action signals a sustained push to weaken the dollar against the yen, which can reduce dollar-based commodity prices and shift import costs. The scale of intervention is modest relative to the broader currency market.
After 1,637 past bearish macro events, US Dollar (Broad) moved a median -0.2% over 5 sessions (39% higher; middle half -0.6% to +0.3%), and -0.2% over 20.
