The Bank of Japan held its monetary policy meeting last week, deciding to raise its policy rate to the highest level since 1995. The summary of opinions from the June 15-16 meeting released this Wednesday shows the central bank clearly signaling that further increases to the benchmark interest rate are necessary.

The summary cited the view of one board member, stating: "Regarding the future conduct of monetary policy, given that core CPI inflation is gradually approaching 2% and overall financial conditions remain accommodative, the Bank should continue raising the policy rate in accordance with changes in economic, price, and financial conditions." This reflects the position held by some of the nine board members.

While last week's hike was the Bank of Japan's first since December and it already indicated a continued upward trajectory for rates, the latest summary did not provide a clear hint on the timing of the next increase. Nevertheless, this document may further solidify market expectations for another rate hike within the year.

Following the decision last week, a survey of economists showed about 90% of respondents expected the central bank to act again before December, with over one-third pointing to October as the likely window for the next adjustment. Economists currently project the terminal rate for this cycle to reach 1.75%, higher than the 1.5% forecast in an earlier survey this month.

Although the summary does not name specific speakers, the content indicates that some members—likely the more hawkish Naoki Tamura or Hajime Takata—believe that with the latest hike to 1%, the Bank of Japan's rate remains significantly below those of other major economies, necessitating further increases in the coming months.

The summary noted one member said, "The neutral interest rate is estimated to be around 2%," adding that "it is desirable to consider, at appropriate times with intervals of several months, whether to further raise the policy rate." Another view suggested rates should be raised "as soon as possible" to a level closer to the neutral range. The Bank of Japan estimates the neutral rate to be roughly between 1.1% and 2.5%.

The meeting was held after Governor Kazuo Ueda was hospitalized on June 9 due to a liver cyst infection, marking the first policy meeting since 2010 to be held in the governor's absence. Ueda was discharged from the hospital early last week.

The summary was released as the yen hovered near its lowest level against the U.S. dollar since 1986, with market expectations for a Federal Reserve rate hike this year gaining traction. As of Wednesday, the yen traded around 161.60 per dollar, with traders remaining alert to potential intervention by Japanese authorities. The Bank of Japan has stated it will closely monitor the impact of exchange rate movements on inflation and the economy. For resource-importing Japan, a weaker yen exacerbates inflationary pressures.

A separate Bank of Japan report released the same day showed corporate service prices remained elevated in June, rising 3.3% year-on-year, marking the third consecutive month at this pace of increase and matching economists' expectations.

Prime Minister Sanae Takaichi is seen as a potential obstacle to Governor Ueda's efforts to normalize interest rates. Takaichi's nominated board candidate, Toichiro Asada, voted against the rate hike at last week's meeting. Another candidate she nominated, Ayano Sato, is set to join the policy board officially at the end of this month.

Ahead of last week's meeting, Minoru Kiuchi, the minister in charge of economic policy who was scheduled to attend the discussions as a government representative, had "strongly" hoped for the central bank to enhance policy coordination with the government.

The summary also revealed that a Cabinet Office official reminded the board of its communication responsibilities regarding interest rate decisions—a statement interpreted as a sign of growing tension between the government and the central bank. The official stated in the summary: "It is important for the Bank to fulfill its accountability regarding the decision to raise rates at this meeting, and also to proactively take appropriate measures when excessive fluctuations occur in economic activity."
