US and Japan Unite in Rare Joint Intervention to Support Yen

The US Treasury and Japan have joined forces for their first joint intervention to support the Japanese yen in nearly three decades. The coordinated action saw a significant drop in the dollar's value against the yen, from approximately 164 yen to around 156-157 yen.

US Treasury Secretary Scott Bessent spearheaded the American involvement, using an unconventional approach by selling euros to purchase yen instead of dollars. President Donald Trump characterized the move as 'a signal of friendship' and noted that the US gained a 'financial benefit' from the operation.

The intervention was motivated by pressing concerns on both sides. Japanese policymakers were worried about the yen's excessive slide, while the US aimed to prevent Japan from selling its substantial US Treasury holdings to support the yen and address concerns about selling pressure on the US Treasury market.

Experts caution that the intervention's effects may be temporary without addressing underlying causes of the yen's weakness, including rising oil prices, uncertainty over government spending, and the slow pace of Bank of Japan rate increases. Chris Turner of ING described it as 'a return to an age of FX activism,' with the US prepared to counter trades opposing its interests.
