BOJ Sees Inflation Win Yet Holds Rates; Why the Hesitation?

A decade ago, the idea that the BOJ could even find a route to its inflation target was pure fantasy. Yet here we are. The central bank now gets to pronounce inflation defeated. Surely that calls for popping the champagne? Not so fast.

Reaching the destination, it appears, is quite different from persuading the board to act.

Today the BOJ left its policy rate at 1.25% on an 8-1 vote, with Takata once again the solitary hawk on the board. He pushed for a quarter-point increase to 1.50%, yet his colleagues were not persuaded. What lies behind that?

The most striking part of today's decision is the BOJ's statement that underlying inflation now sits at a level largely aligned with the 2% target. Officials also see price growth staying near that mark going forward. For an institution that spent over a decade trying to restore inflation durably, that is a notable milestone.

In addition, the BOJ revised its core inflation outlook for fiscal year 2027 upward to 2.6% from 2.4%.

If price growth is already where officials have been seeking, why the reluctance to accelerate policy moves?

The board's overwhelming majority, it seems, still favours a cautious path. With a rate increase only just delivered in September, there is scant desire to follow up quickly until the effects of earlier tightening on the economy become clearer. So very BOJ, isn't it?

Yet the larger issue, in my view, is the political headache.

The two board members appointed by Prime Minister Takaichi — Asada and Sato — voted against the September rate increase. That stands as a reminder that winning board approval for more hikes may not be easy, even with the BOJ's declared inflation win.

Next year may become even more difficult for the central bank. Takaichi gets the chance to fill two further board seats in 2027. Should those choices prove similarly inclined toward easy policy — as they probably will — Ueda could be facing a more fractured committee.

Despite today's message, market pricing puts around 57% odds on a further 25 bps move in December. That is hardly a strong vote of confidence in the next step, nor does it suggest much faith that the BOJ will accelerate tightening next year.

At his press appearance later, Ueda will probably restate that more tightening remains an option while leaving the timing intentionally unclear, true to form. The key detail to watch is whether he stresses the inflation achievement or the importance of weighing growth, wages and financial conditions.

If he does not give a firmer signal, I suspect investors will enter December still asking the same question.

Having fought for so long, the BOJ has finally checked the inflation box. The tougher task now is bringing everyone along on the next step.
