BOJ Rate Hike Expectations Rise Ahead of September Meeting

Bank of Japan policymakers are preparing a series of closely watched speeches ahead of the BOJ’s September 17-18 policy meeting, as expectations grow that the central bank will deliver another interest rate hike.

BOJ board member Kazuyuki Masu is scheduled to give a speech and hold a news conference on September 10, according to an announcement from the central bank on Friday. His appearance will come after Deputy Governor Ryozo Himino speaks on August 27 and hawkish board member Hajime Takata addresses an audience on September 2.

The speeches could provide important clues about the Bank of Japan’s interest rate outlook and the likelihood of a September rate increase. In the past, BOJ officials have often used scheduled public appearances to prepare financial markets for upcoming monetary policy changes.

Expectations for a September BOJ rate hike have strengthened following last week’s coordinated Japan-U.S. intervention in the foreign exchange market to support the yen. Comments from U.S. Treasury Secretary Scott Bessent indicating a preference for an earlier Japanese rate increase have added to speculation that policymakers will act at their next meeting.

Sources have suggested that recent developments have made a September increase increasingly likely as Japanese authorities seek to address persistent weakness in the yen.

The Bank of Japan ended its decade-long era of massive monetary stimulus in 2024 and has gradually tightened monetary policy since then. Its latest rate increase came in June, when the BOJ lifted its policy rate to 1%, the highest level in 31 years.

Despite those increases, critics have argued that the BOJ’s gradual approach to monetary tightening has contributed to continued pressure on the Japanese currency. The wide interest rate gap between Japan and the United States has encouraged investors to favor higher-yielding dollar assets, weighing on the yen.

The yen’s decline to around 40-year lows has increased pressure on Japanese policymakers to respond more aggressively. Investors will therefore closely monitor the upcoming BOJ speeches for signals about the pace of future rate hikes.

USD/JPY could remain particularly sensitive to comments from Masu, Himino and Takata as markets assess whether a September BOJ rate hike is effectively becoming the central bank’s next policy move.
