Market pricing for a Bank of Japan rate increase on September 18 has climbed to 97 percent. A board member stated that underlying inflation is approaching the 2 percent target.

The probability of a Bank of Japan interest rate hike on September 18 stands at 97 percent. This figure reflects strong market confidence in further monetary tightening. BOJ board member Kazuyuki Masu stated that underlying inflation is nearing the 2 percent threshold. He argued that the central bank must continue raising its benchmark rate to prevent inflation from exceeding this level.

Masu described financial conditions as still accommodative. He emphasized the need to adjust the degree of monetary easing. His remarks align with a broader shift toward hawkish policy among BOJ board members. The current benchmark rate sits at 1 percent. The market expects a 0.25 percentage point increase if the hike occurs.

Economic Data Supports Tighter Policy

Japan’s second-quarter gross domestic product growth was revised up to an annualized 1.4 percent. Wage growth in July reached its highest level in approximately 30 years. These data points reinforce the case for additional rate hikes. Masu noted that higher transport costs for imported raw materials are rising. Fertilizer prices are also increasing, which pushes up food costs.

External Factors Drive Inflation Risks

Masu identified the war in Iran as a driver of higher fuel and chemical prices. These gains are spreading across a wide range of goods. He warned that these price increases could become persistent. This trend risks lifting overall inflation beyond temporary shocks. US Treasury Secretary Scott Bessent also called for additional BOJ rate increases.

Market Pricing Reflects Consensus

The swaps market prices the September 18 hike at a 97 percent likelihood. Masu is the last scheduled BOJ board member to speak before the meeting. His previous comments signaled the need for policy adjustment ahead of the June hike. According to GN markets/policy (en-US), this stance bolstered expectations for the upcoming move. The central bank aims to maintain price stability through these measures.
