BOJ Nears a Historic Judgment: Japan’s Underlying Inflation May Finally Be at 2%

The Bank of Japan is approaching a judgment that would have sounded extraordinary for much of the past three decades: Japan may finally have an underlying inflation rate of about 2%.

Jiji/The Japan Times reported on October 5 that the BOJ is considering concluding that underlying inflation has reached roughly 2%, with the assessment potentially appearing as early as the October 30 Outlook for Economic Activity and Prices, after the central bank’s October 29–30 policy meeting.

This is not the same as saying CPI is above 2%

The most important distinction is that the BOJ’s “underlying inflation rate” is not a single consumer-price index.

In a March 2026 review, the BOJ’s Monetary Affairs Department described three broad approaches to identifying underlying inflation: measures that remove volatile items, measures of medium- to long-term inflation expectations, and model-based estimates of the inflation trend.

That means a temporary jump in gasoline, rice or imported energy prices does not by itself prove that the 2% target has been sustainably achieved. The BOJ is looking for something deeper: wage gains feeding into prices, firms behaving as though moderate inflation is normal, inflation expectations settling near 2%, and service prices rising broadly enough to persist after temporary shocks fade.

The story began with “2% in about two years”

The current target dates to January 22, 2013, when the BOJ set a 2% year-on-year increase in consumer prices as its price-stability objective. Japan’s defining macroeconomic problem at the time was deflation: weak pricing power, stagnant wages and expectations that prices would not rise.

In April 2013, under Governor Haruhiko Kuroda, the BOJ launched Quantitative and Qualitative Monetary Easing. The aim was to achieve 2% inflation “at the earliest possible time,” with roughly two years in mind. The central bank dramatically expanded the monetary base, bought huge quantities of government bonds and later accumulated exchange-traded funds as well.

The target proved far harder to reach sustainably than expected. Oil-price declines, weak demand after tax increases, subdued wages and deeply embedded deflationary expectations repeatedly pulled inflation lower. In 2016, the BOJ introduced negative interest rates and later adopted yield-curve control to constrain longer-term borrowing costs.

March 2024 changed the framework

A major turning point came on March 19, 2024. The BOJ said it had confirmed a virtuous cycle between wages and prices and judged that it was possible to foresee the 2% target being achieved sustainably and stably toward the end of its projection period.

On that basis, the BOJ ended negative interest rates and the yield-curve-control framework that had defined the later years of extraordinary easing. Short-term interest rates once again became the principal policy instrument.

But that was still not the same as saying underlying inflation had already reached 2%. The language was forward-looking: sustainable 2% inflation had become foreseeable.

In 2026, the vocabulary shifted from “approaching” to “overshoot risk”

BOJ language has become steadily more assertive in 2026.

Its March review said underlying inflation was moving closer to 2%. In May, policy-board member Kazuyuki Masu said that, while still below 2%, the underlying rate had come considerably closer to the target.

By June, policymakers were openly discussing the risk that underlying inflation could overshoot the target, especially as higher oil prices linked to Middle East tensions spread through the economy. In August, Deputy Governor Himino said that with underlying inflation approaching 2% and financial conditions still accommodative, the BOJ would continue raising the policy rate as warranted by economic, price and financial conditions.

Then, on September 18, the BOJ raised its policy-rate target to around 1.25%, taking Japan further away from the near-zero rate regime that had shaped an entire generation of economic behavior.

From creating inflation to containing it

The philosophy of policy has changed. During the deflation era, the BOJ was trying to push inflation upward toward 2%. Today, it must prevent an inflation trend near 2% from falling away while also preventing it from becoming entrenched above target.

That is a different central-banking problem. In the past, the key threats were weak demand, a strong yen and stagnant wages. Now the risks include a weak yen, energy shocks, firms passing costs through more readily, stronger wages, service-sector inflation and changes in inflation expectations.

The BOJ’s July Outlook Report projected core CPI inflation, excluding fresh food, at 2.5% in fiscal 2026, 2.4% in fiscal 2027 and 2.0% in fiscal 2028. The significance is not merely that inflation is high today, but that policymakers see it converging toward 2% over the forecast horizon.

Why wages matter so much

The BOJ has never wanted inflation driven only by imported energy or food. It has sought a self-sustaining domestic mechanism: wages rise, companies pass some higher labor costs into prices, stronger nominal income supports demand, and that in turn sustains wages.

An oil shock can lift CPI sharply, but the effect fades when oil prices fall. Wage and service-price inflation can be much more persistent. That is why the BOJ watches annual labor negotiations, services prices, firms’ price-setting behavior and inflation expectations so closely.

The real question is whether Japan has moved from a world in which companies fear losing customers if they raise prices to one in which modest price increases are accepted as a normal response to higher wages and costs.

Tokyo inflation at 2.7% does not settle the question

Tokyo’s core consumer-price index rose 2.7% from a year earlier in September, Reuters reported on October 2. A measure excluding both fresh food and fuel rose 3.0%.

Those numbers strengthen the case for continued policy normalization, but they do not mechanically answer the underlying-inflation question. Subsidies, energy prices and food costs can all distort headline and core readings. The BOJ is trying to identify what remains after those temporary forces fade.

That is why the language in the October 30 Outlook Report could matter as much as the next rate decision.

A 2% judgment would not automatically mean an October rate hike

Even if the BOJ formally concludes that underlying inflation has reached 2%, it does not follow that the policy rate must rise at the same meeting.

The central bank repeatedly says the timing and pace of adjustment depend on the probability of its central outlook being realized and on risks in both directions. The September increase to 1.25% is still fresh, and policymakers need to assess its effect on households, companies and financial markets.

Reuters reported that September meeting discussions included calls for faster rate increases, but also caution from the government side. The latest Tankan showed strong confidence among large manufacturers but weaker sentiment among nonmanufacturers, illustrating why the BOJ may want to distinguish between a structural inflation judgment and the exact timing of another move.

The next debate is where rates ultimately belong

If the BOJ officially recognizes underlying inflation at 2%, the market debate will increasingly shift from whether Japan has escaped deflation to how high interest rates ultimately need to go.

An economy with sustained 2% inflation would normally carry higher nominal interest rates than an economy stuck near zero inflation. But Japan’s households, businesses, banks and government finances have all adapted to extremely low borrowing costs over many years. Mortgages, corporate debt, government interest expense, bank margins and insurance portfolios will all respond as rates rise.

Former BOJ board member Asahi Noguchi told Reuters on October 5 that Japan no longer needed the degree of monetary and fiscal stimulus associated with its reflation era, while warning that pushing rates to 2% could shock an economy accustomed to low borrowing costs. His view is not BOJ policy, but it captures the next argument: what does a normal interest-rate structure look like in a Japan with normal inflation?

The end of the deflation story would be the start of a harder job

The 2% target introduced in 2013 was designed to pull Japan out of an abnormal low-inflation equilibrium. The policies that followed—massive asset purchases, negative rates and yield-curve control—were equally extraordinary.

Negative rates and yield-curve control ended in 2024. By 2026, the policy rate had moved above 1%. If the BOJ now formally says underlying inflation has reached around 2%, the transition will move another step forward.

That would not mean the job is finished. Maintaining inflation around 2% without damaging growth, crushing wage gains or allowing inflation expectations to run too high may be harder than generating inflation in the first place.

The BOJ’s next phase is not a war against deflation. It is the more ordinary—and in Japan, unfamiliar—task of managing inflation. That is why the wording of the October Outlook Report could matter far beyond a single interest-rate decision.
