BOJ’s December Hike Is Consensus. The Yen Is Already Looking Past It

BOJ’s December Hike Is Consensus. The Yen Is Already Looking Past It.

TOKYO — The October 29-30 meeting minutes, published Tuesday, removed whatever ambiguity remained. One board member put it plainly: the central bank should decide on the next hike “at a feasible timing without being excessively cautious” . Another went further, saying underlying CPI has hit 2% and the BOJ “needs to raise the policy rate to neutral as soon as possible” . Swap markets now assign roughly 70% odds to a December move . Mizuho Securities expects 25bp increments in December, March, and June, taking the policy rate from 1.25% to 2.00% .

Governor Ueda did nothing to push back against any of this. At his post-meeting press conference on October 30, he said the board would evaluate the economy and risks “at every policy meeting, including the next one” . That is BOJ-speak for yes.

And yet dollar-yen sits at 157.95, essentially unchanged from where it traded a week ago, and up 3.17% from a year earlier . The currency has absorbed the hawkish guidance, the minutes, the Mizuho call for a 2% terminal rate, and decided none of it matters enough to bid the yen.

The arithmetic explains why. A hike to 1.5% in December leaves Japan’s policy rate 300 basis points below the Fed’s target range, assuming the December FOMC delivers the 25bp move that markets price at 90% probability . The spread narrows by 25bp. The carry trade does not die. It adjusts its spreadsheets and waits for the next meeting.

What the yen is actually trading is not the December decision. It is the question of what comes after. The BOJ’s own communication has been deliberately vague on the terminal rate. Ueda has acknowledged that neutral is somewhere between 1.1% and 2.5%, an unobservable range wide enough to drive a truck through. Mizuho’s 2% forecast implies three more hikes after December. The BOJ has not endorsed that path, and the minutes offer no guidance on pace beyond “feasible timing.”

This is the gap that matters. The market is pricing a December hike with near-certainty and treating everything beyond it as a data-dependent mystery. If Ueda’s post-meeting guidance on December 18 is as noncommittal as his October performance, the hike will land and the yen will sell off. A tightening delivered with a shrug is not a tightening at all. It is a confirmation that the BOJ is still feeling its way toward neutral while the Fed sits at 4.50%-4.75% and the ten-year Treasury yields 5.15% .

The domestic data does not force the BOJ’s hand in either direction. October Tokyo core CPI came in at 2.6% year-on-year, down from 2.7% but still above target . Core-core, the measure that strips out fresh food and energy, printed 2.6% after September’s 2.9% . The softening is marginal. It does not argue for pause. It does not argue for acceleration either.

The one variable that could change the calculus is the global risk backdrop. Ueda said on November 6 that the BOJ “may be obliged to deploy unconventional policy tools again depending on the severity of the economic shock” that could hit Japan . That sentence, delivered at an IMF seminar, was read in some corners as a hedge against a disorderly market. It is more accurately read as a reminder that the BOJ’s toolkit is asymmetric. It can hike from 1.25% to 1.5%. If the AI trade cracks and global risk assets sell off in a disorderly fashion, the BOJ has no conventional room to respond. Unconventional tools are what remain.

That asymmetry is why the yen refuses to strengthen on hawkish guidance. The market is not betting against a December hike. It is betting that a December hike is the last clean one the BOJ gets before it has to start worrying about the other side of the cycle. A central bank that hikes once and then starts muttering about unconventional easing is not a central bank that deserves a stronger currency.

December 18 is the date. The hike is priced. The guidance is the only thing left to trade. Ueda has one press conference to convince the market that 1.5% is a step on a path rather than the end of one. The minutes suggest the board wants to move faster. The currency suggests nobody believes it will.
