Bank of Japan's September Rate Hike Expectations Grow

The Bank of Japan (BOJ) has scheduled a series of speeches by its board members in the lead-up to its next policy meeting on September 17-18, a move that is fueling market speculation about a potential interest rate hike.

Board member Kazuyuki Masu is set to deliver a speech and hold a news conference on September 10, joining previously announced appearances by hawkish board member Hajime Takata on September 2 and Deputy Governor Ryozo Himino on August 27.

The clustering of these events mirrors the BOJ's past practice of using pre-scheduled speeches to signal upcoming policy changes. Takata notably dissented from the July decision to keep rates steady, advocating for a hike to 1.25%. Both Masu and Himino are viewed by markets as leaning toward a near-term rate increase.

Adding to the anticipation, U.S. Treasury Secretary Scott Bessent has indicated he expects to meet BOJ Governor Kazuo Ueda at the G20 finance leaders' meeting on August 31 and September 1. If Ueda holds a press conference after that gathering, it would draw significant attention from investors seeking clarity on the BOJ's next move.

Market sources suggest that last week's joint Japan-U.S. yen intervention and Bessent's comments favoring an early rate hike have all but locked in a September increase. Nomura Securities strategist Mari Iwashita noted that the BOJ has historically followed through with rate hikes after Bessent's remarks on Japanese monetary policy. She also pointed to rising domestic producer prices as a factor supporting a hike.

The BOJ ended its massive stimulus program in 2024 and has since raised rates several times, most recently in June, bringing the policy rate to a 31-year high of 1%. However, the gradual pace of increases has been blamed for the yen's slide to a 40-year low, as the wide Japan-U.S. rate gap continues to weigh on the currency.
