The Bank of Japan raised interest rates as expected, yet uncertainty surrounding the ultimate policy destination has grown. Deputy Governor Shinichi Uchida explicitly stated that the estimated range for the neutral rate is too broad to be useful for practical policy decisions. This remark implies that even if the policy rate has reached the lower bound of the neutral rate range published by the central bank, it is insufficient to prompt a slowdown in the pace of rate hikes.
In a research report released on June 16th, the Bank of Japan raised its policy rate by 25 basis points to 1% at this meeting, aligning with widespread market expectations. With Governor Kazuo Ueda absent from the meeting, the vote was conducted by eight board members. Asada, the first board member appointed by the government of Sanae Takaichi, cast the sole dissenting vote, citing downside risks to production and employment.
Regarding government bond purchases, the central bank decided to maintain its current reduction plan until March 2027, after which it will suspend further cuts and keep monthly purchases at approximately 2 trillion yen. According to the Wind trading desk, JPMorgan's latest report suggests this rate hike will not exert significant downward pressure on the economy and anticipates the central bank will raise rates again in October, by which time inflationary pressures are expected to be more pronounced.
Uncertainty Surrounding the Neutral Rate
The market's most closely watched statement from this meeting came from Deputy Governor Shinichi Uchida's characterization of the neutral rate.
He clearly stated that the "estimated range for the neutral rate is too broad to be used for actual policy decisions." He framed the current rate hikes as a "policy calibration toward the neutral level," adding that "we cannot judge in advance when we will reach a neutral stance; we will only know after we have arrived."
This phrasing is more direct than Governor Kazuo Ueda's previous statements. While Ueda has long emphasized the uncertainty in estimating the neutral rate, Uchida's remarks were more explicit. The practical implication is that even though the policy rate has risen to the lower bound of the central bank's published neutral rate estimate, this fact alone does not mean the central bank will become more cautious about further rate increases.
Internal Divisions Over Inflation Assessment
The overall stance conveyed in the policy statement and press conference was that core inflation is in a process of approaching 2%. However, there is disagreement within the board on this assessment.
Board members Takada and Tamura dissented from this view, arguing that core inflation has already reached the 2% level. Uchida stated at the press conference that most other members believe this target will be achieved between the second half of fiscal 2026 and the first half of fiscal 2027.
Regarding the characterization of inflation risks, the policy statement noted "risks of core CPI inflation deviating upward from the 2% price stability target." However, JPMorgan pointed out this is not new information—the core inflation forecast (excluding fresh food and energy) in the central bank's April Outlook Report already implied inflation persistently above 2% throughout the projection period (to fiscal 2028). Uchida also stated that the primary background for proceeding with the rate hike at this meeting, compared to April, was the subsiding of downside economic risks.
Quantitative Tightening: Path Maintained, Pace to Slow
On government bond purchase arrangements, the central bank decided to maintain its current reduction plan until March 2027, after which monthly purchases will be stabilized at around 2 trillion yen with no further cuts. The central bank also indicated this arrangement could be adjusted if circumstances warrant.
JPMorgan analysis suggests that if this policy is maintained, the central bank's balance sheet will continue to shrink, but the pace of contraction will slow from 2028 onward.
Uchida's explanation for the bond purchase decision was relatively brief, stating only that "market functioning has continued to improve steadily, so we decided to maintain the status quo for the time being." JPMorgan noted this explanation appeared somewhat cursory compared to the rigorous logic applied to other topics.
Political Variables: Dissenting Vote and Governor's Absence
Two noteworthy political signals emerged from this meeting. First, Asada, the first central bank board member appointed by the Sanae Takaichi government, cast a dissenting vote. JPMorgan noted that although this decision followed thorough prior communication and was fully priced in by markets, this dissenting vote may indicate that strong resistance to central bank policy normalization persists within the government.
Second, Governor Kazuo Ueda was absent from this meeting and did not participate in the vote. It is notable that Uchida participated remotely and retained his voting rights during a previous hospitalization, whereas Ueda was unable to vote this time. Uchida stated only that the reason was "related to medical treatment," offering no further details.
Additionally, Uchida avoided questions regarding the consistency of central bank policy with the Takaichi government's fiscal policy.
JPMorgan Anticipates Another Rate Hike in October
JPMorgan maintains its previous assessment, expecting this rate hike will not generate significant downward economic pressure.
The firm anticipates that as inflationary pressures become more evident around summer, the Bank of Japan will raise rates again in October.
Uchida reiterated at the press conference that the central bank will continue to advance rate hikes as core inflation approaches 2%, emphasizing that "it will be crucial to keep inflation stable around 2% going forward." With the neutral rate lacking a clear anchor, the trajectory of inflation data will become the core basis for the market to judge the central bank's policy path.
