Japan’s Core Inflation Expected to Miss BOJ Target for Fourth Straight Month in May
Japan’s core consumer inflation likely held at 1.4% in May — unchanged from April and below the Bank of Japan’s 2% target for a fourth consecutive month — as the end of government fuel subsidies offset upward pressure from Iran war-driven energy prices, according to a Reuters poll of 16 economists published on Friday, June 12.
The nationwide core consumer price index, which includes energy items but excludes fresh food prices, is expected to have risen 1.4% in May from a year earlier, according to the median estimate of the poll, unchanged from April when it marked the slowest increase since March 2022. The Internal Affairs Ministry will release the official CPI data at 8:30 a.m. on Friday, June 19, Japan time. tradingeconomics
The forecast arrives three days before the Bank of Japan’s June 15-16 policy meeting — at which the central bank is widely expected to raise its short-term policy rate to 1% from 0.75%, a level not seen in Japan in three decades.
Subsidies Versus Energy Shock: Two Forces in Tension
The flat forecast for May reflects competing pressures that have kept Japan’s inflation trapped below target even as global oil prices remain elevated.
Japan’s annual core inflation slowed to a four-year low in April due to the effect of subsidies on fuel and education, though analysts expect surging fuel costs from the Middle East war to accelerate price growth in coming months. TRADING ECONOMICS
Government fuel subsidies were scheduled to expire in April 2026, and the removal of the provisional gasoline tax — implemented in November 2025 — was expected to partially offset the subsidy expiry’s impact on pump prices. In May, those two forces are estimated to have roughly cancelled out, holding core CPI flat at April’s pace. tradingeconomics
A 10.6% drop in education fees, reflecting the nationwide expansion of education subsidies that took effect in April 2026, weighed on service-sector inflation in April and is expected to continue doing so through May. TRADING ECONOMICS
Credit Agricole Corporate and Investment Bank analysts said in a note that the rise in crude oil prices driven by geopolitical risks is expected to complicate movements in Japan’s price indicators. Should crude oil prices remain elevated and there is no expansion of energy subsidies, core inflation could rise toward 3% by the end of the 2026 fiscal year. tradingeconomics
Ueda’s Absence from the Rate Vote
The inflation data lands amid unusual circumstances at the Bank of Japan. Governor Kazuo Ueda was hospitalised on June 10 for treatment of an infected liver cyst and will miss the June 15-16 policy meeting — the first time a BOJ governor has missed a policy-setting meeting since the current arrangement began in 1998. Ueda, 74, is expected to remain in hospital for approximately two weeks, work remotely, and attend the next policy meeting scheduled for July 30-31. The Citizen
Deputy Governor Ryozo Himino will preside over the rate review in Ueda’s place, while Deputy Governor Shinichi Uchida is set to host the post-meeting press conference. United Nations in Europe
Ueda will submit a written statement on his policy view but will not participate in next week’s vote. The Citizen
Markets have largely absorbed the governor’s absence without revising the rate expectation. A Bloomberg survey showed nearly all economists expect the board to raise the policy rate to 1%, a level not seen in three decades. The BOJ’s policy rate stood at minus 0.1% as recently as early 2024 before the central bank embarked on its most aggressive tightening in nearly two decades. Business Recorder
The communication question is more contested. Mari Iwashita, Executive Director of Rates at Nomura Securities, said the BOJ may decide not to send clear signals about the future path of rates given Ueda’s absence. “Given the uncertainty about how long it will take for the governor to fully recover, it also becomes less clear whether the BOJ would hike again this year,” Iwashita said. un
The Trajectory Since the Iran War
The current below-target inflation streak is a direct reversal of conditions a year earlier. While government measures are offsetting some of the price pressure from the energy shock, BOJ policymakers are issuing hawkish signals pointing toward the chance of an interest rate hike in June. TRADING ECONOMICS
Japan’s government rolled out new fuel subsidies from March 2026, with Prime Minister Sanae Takaichi capping pump prices at an average of 170 yen per litre nationwide. Finance Minister Satsuki Katayama estimated a subsidy cost of approximately 300 billion yen per month if gasoline reached 200 yen per litre, the level Takaichi had warned it could hit without intervention. The subsidies drove energy costs down 5.7% in March even as global oil markets remained disrupted. tradingeconomics
The paradox facing the BOJ is that the same subsidies designed to shield households from energy price spikes have mechanically suppressed the inflation figures that would otherwise justify aggressive tightening. Reuters, citing sources familiar with the BOJ’s thinking, reported in April that the central bank was set to cut its growth forecast for the 2026 fiscal year while sharply revising up its inflation forecast for the same period. tradingeconomics
Regional and Global Impact
A move to 1% at the June 16 meeting would mark the culmination of a normalisation path that began in March 2024, when the BOJ exited negative interest rates for the first time since 2016. The last time Japanese rates were at 1% was in the mid-1990s, when Japan’s economy was emerging from the aftermath of the asset-price bubble. Business Recorder
The decision carries direct implications for global currency markets. A BOJ rate hike combined with a weaker-than-expected US dollar — under pressure from rising US inflation and uncertainty about Federal Reserve policy — would narrow the interest-rate differential that has kept the yen weak. Markets will scrutinise Uchida’s press conference closely for forward guidance signals on the pace of future tightening, given Ueda’s absence removes his direct communication from the meeting.

Background
The BOJ’s tightening cycle began in March 2024, when the central bank raised its policy rate from negative 0.1% for the first time in eight years, marking the end of its landmark yield curve control framework. The Iran war, which began in late February 2026, has pushed global oil prices sharply higher, introducing an inflationary shock that runs counter to Japan’s domestic subsidy framework. Japan’s government formally requested the BOJ achieve a dual mandate — realising both strong economic growth and stable inflation — adding a political dimension to the monetary policy decisions ahead. Japan imports nearly all of its oil, making it acutely exposed to energy price shocks driven by Middle East conflict and any disruption to Strait of Hormuz shipping. Business Recordertradingeconomics
What Happens Next
The Internal Affairs Ministry will release the official May nationwide CPI data on Friday, June 19, the day after the BOJ’s June 16 rate decision. Ueda is expected to return for the July 30-31 policy meeting. Whether the BOJ provides any guidance on the pace of further tightening in Uchida’s June 16 press conference will determine whether markets price additional hikes into the second half of 2026. If energy subsidies are not expanded and crude oil prices remain elevated, analysts at Credit Agricole expect Japan’s core inflation could rise toward 3% by the end of the 2026 fiscal year — a reading that would sharply revive the case for continued BOJ tightening. tradingeconomics + 2
