U.S. Treasury Secretary Scott Bessent has launched an extraordinary public pressure campaign to boost the Japanese yen, challenging traders and signaling his resolve to push for monetary tightening in Japan. Bessent's direct engagement includes overseeing the first U.S. purchases of yen in three decades and planning buybacks of U.S. Treasuries, suggesting an unprecedented level of intervention and influence on Japanese monetary policy. He stated at a Southern Methodist University event, "I am the house now, so when we intervene with the Japanese yen, I have pretty good insight into what the Japanese, what the Bank of Japan is going to do, what Japanese policymakers are going to do." This aggressive stance is raising expectations for a significant monetary tightening campaign from the Bank of Japan.
Bessent's actions are placing the Bank of Japan under significant duress to accelerate interest rate hikes. After a rare joint U.S.-Japan intervention to prop up the yen, Bessent reportedly told Reuters that recent yen moves were not disorderly, but expressed hope that BOJ Governor Kazuo Ueda would "do the right thing" regarding monetary policy. This effectively locks the BOJ into further rate hikes, with analysts like Izuru Kato of Totan Research stating that the July joint intervention was a message from Bessent for Japan to "get its act together on inflation." Oxford Economics now anticipates the BOJ to raise rates in September and December this year, followed by another hike in April 2027, a faster pace than previously expected.
The U.S. Treasury Secretary's push also signals an end to Japan's long-standing "Abenomics" policy of massive monetary stimulus and big spending, a stance that puts him at odds with dovish Prime Minister Sanae Takaichi. Takaichi, a proponent of Abenomics, has laid out ambitious spending plans, which have unnerved investors and pushed Japanese government bond yields to three-decade highs, potentially affecting U.S. Treasury yields. The divide between Bessent and Takaichi over the optimal path for the BOJ, with Takaichi being wary of rapid rate increases, risks undermining efforts to strengthen the yen despite their rare unity in intervening in currency markets. This tension highlights the delicate balance between international economic cooperation and domestic policy autonomy.
