Tamura is the most hawkish voice on the BOJ board and his comments will be read as the outer boundary of where policy could go rather than consensus, but the specificity of the 2% neutral rate target and the every few months cadence language directly echoes what appeared in the June Summary of Opinions, meaning he is not an outlier on direction, only on pace. His dissent on the JGB taper pause is the most market-sensitive element for the long end of the curve: a board member actively pushing for faster balance sheet reduction, framing the pause as a mistake, keeps upward pressure on super-long JGB yields and complicates the BOJ’s communication that the halt was a stability measure rather than a policy retreat. The framing of Japan’s situation as fundamentally different from the Fed and ECB, with the policy rate still below neutral and inflation expectations not yet anchored, removes any ambiguity about whether the hiking cycle has further to run. For JPY, the remarks are constructive on the rate differential argument but the yen’s failure to respond to similar language in recent weeks caps the near-term impact.

BOJ board member Tamura said underlying inflation has already reached 2% and called for rate hikes every few months toward a 2% neutral rate, adding the BOJ should not hesitate to accelerate if upside price risks heighten.

Summary:

• BOJ board member Naoki Tamura said it is important to push the policy rate closer to the neutral level to avoid being forced into sharp rate hikes later, and put the neutral rate at around 2%, per his remarks on Wednesday
• Tamura said his preferred pace is a rate hike once every few months toward the 2% neutral level, and that the BOJ should not hesitate to accelerate hikes or move by a larger margin if upside price risks heighten, per his comments
• Tamura said his view is that underlying inflation has already reached 2%, and that upside price risks exist regardless of Middle East developments, per his remarks
• The board member said Japan’s situation differs fundamentally from that of the Fed and ECB in that the BOJ’s policy rate remains below neutral and inflation expectations are not sufficiently anchored, per Tamura
• Tamura said he voted against the BOJ’s decision to pause its JGB purchase tapering from the next fiscal year, arguing the bank should bring its bond holdings to normal levels as soon as possible, per his remarks
• Tamura said the recent rise in long-term interest rates is consistent with fundamentals and reflects market participants’ views on inflation and the monetary and fiscal policy outlook, per his comments

Bank of Japan board member Naoki Tamura delivered his most explicit public case yet for an accelerated tightening cycle on Wednesday, calling for rate hikes at a pace of once every few months toward a neutral rate of around 2% and warning that delaying the journey risks forcing the central bank into sharper moves later.

Tamura said his view is that underlying inflation has already reached the BOJ’s 2% price stability target, removing what he characterised as the remaining justification for maintaining an accommodative policy stance. He said upside risks to prices exist regardless of how Middle East developments unfold, a direct rebuttal to the argument that the Iran conflict’s resolution reduces the inflation threat. If those upside risks intensify, Tamura said the BOJ should not hesitate to accelerate the pace of hikes or move by a larger increment than the market currently expects.

The board member drew a pointed distinction between Japan’s policy position and that of the Federal Reserve and European Central Bank, noting that unlike those institutions the BOJ’s rate remains below neutral and inflation expectations are not yet sufficiently anchored. That framing implies the BOJ’s tightening cycle has structural ground to cover that its peers have already traversed.

Tamura also disclosed that he voted against the board’s decision to pause the reduction of JGB purchases from the next fiscal year, arguing the bank should normalise its bond holdings as quickly as possible. The dissent puts him at odds with the majority on balance sheet policy and keeps upward pressure on long-term yields, which Tamura said are rising in line with fundamentals and reflect market views on inflation and the policy outlook rather than representing any disorderly move.
