BOJ Members Reveal the Steep Climb to a Neutral Policy Rate

Japan's central bank is staring down a mountain of economic contradictions. The path to normalizing interest rates—a move markets have craved for years—is proving far more treacherous than a simple policy flip.
The Inflation Mirage
Sure, prices are rising. But BOJ officials whisper about the fragile foundation. Is this sustainable wage-driven inflation, or just a costly hangover from global supply shocks and a weak yen? Tapping the brakes too soon could slam the economy back into deflationary quicksand.
A Debt-Laden Tightrope
Here's the real bind: Japan's public debt tower looms over everything. The government's balance sheet is the world's most indebted, making even modest rate hikes a fiscal nightmare. Every basis point increase balloons debt-servicing costs, a political third rail no one wants to touch. It's the ultimate case of being trapped by your own success in keeping borrowing cheap.
Global Winds vs. Domestic Doldrums
While the Fed and ECB pivot, Japan's economy moves to its own slow beat. External demand wobbles, and domestic consumption remains stubbornly timid. Raising rates into that headwind? It's the policy equivalent of raising sails in a dead calm—lots of noise, little forward motion, and you risk capsizing the boat.
The result is a central bank playing a high-stakes game of 'chicken' with economic reality. They're armed with a forward guidance playbook, but the market's reading a different script. Neutrality isn't a switch to flip; it's a distant summit shrouded in fog. And getting there requires navigating a path littered with the broken forecasts of economists who thought they saw it clearly—a classic reminder that in central banking, the only certainty is the promise of more carefully worded statements.
BOJ members outline the challenges faced in achieving a neutral policy rate
Sources pointed out that the key takeaways from the two-day meeting clearly indicate that the Bank of Japan (BOJ) is still working on a neutral policy rate. To support this claim, one member of the bank’s board clarified that, “We can say there is still a significant distance to reach the neutral interest rate.”
After the member made this statement, the Governor of the BOJ, Kazuo Ueda, commented that they find it challenging to determine this level. Ueda made these remarks during a press conference just after the December 19 finding. At this particular moment, reports noted that a study carried out by the bank indicated that the neutral rate lies within a wide range of approximately 1% to 2.5%.
The study also demonstrated that some members concurred with Ueda’s argument on the neutral rate and acknowledged the difficulty in identifying it. This situation prompted several members to present some suitable solutions to address the matter.
One member proposed that it is prudent for the BOJ to embrace a flexible approach as it interprets this level. Another member argued that instead of focusing on a certain level, the bank should be flexible in making decisions regarding its policy.
In the meantime, sources mentioned that the BOJ decided to raise its policy rate to 0.75% at the end of the two-day meeting. This percentage represented the policy rate’s all-time high since 1995. It is worth noting that markets were not shocked by this increase because they mostly anticipated this shift in policy rate. This was after Ueda hinted at the possibility of lowering the amount of monetary easing before the decision.
Sanae Takaichi vows not to criticize Ueda’s plans
Concerning Ueda’s decision to increase the BOJ’s policy rate, reports noted that the Governor pointed out the growing uncertainties surrounding the future. He noted this situation at a time when the government’s demand for cheap loans conflicts with a weakening yen, consequently increasing the prices set on imports.
On the other hand, reports highlighted that the Prime Minister of Japan, Sanae Takaichi, is currently tackling issues related to a surge in the cost of living after previously describing the concept of raising rates as “stupid.”
Since assuming her role in October of this year, the Japanese first female prime minister has refrained from criticizing the plans Ueda adopts in attempts to lower monetary easing, concentrating instead on addressing concerns about inflation.
Nonetheless, sources highlighted that Takaichi should also consider adopting preventive measures to prevent bond yields from rising too rapidly as she prepares the government budget for 2026. This budget is typically released in late December.
Meanwhile, reports from earlier this month noted that benchmark 10-year bond yields reached a level of 1.97%, marking the highest peak in 18 years. This situation triggered the Governor of the BOJ to issue a warning that they are surging “somewhat fast.”
In a statement, Ryutaro Kono, chief Japan economist at BNP Paribas, argued that, “Given the Takaichi administration’s preference for low interest rates, we believe that rate hikes will likely happen about every six months,” adding that “the risk of the BOJ needing to speed up tightening due to currency changes is not small.”
