Japan’s measure of core consumer inflation that excludes fresh food registered a 1.6% year-on-year increase in February, slipping below the Bank of Japan’s 2% inflation objective for the first time in nearly four years, data released on Tuesday showed.
The reading undershot the median market expectation of a 1.7% rise and followed a 2.0% gain in January. Economists noted the decline reflects, in part, the influence of policy measures aimed at blunting the impact of higher energy costs on households.
A related gauge that removes both fresh food and fuel - a series the BOJ regards as a clearer signal of demand-driven inflation - rose 2.5% in the year to February, easing from a 2.6% increase in January.
The price dynamics come as the central bank has already shifted away from a decade-long, large-scale easing program, ending massive stimulus in 2024 and lifting interest rates in several steps, including a move in December. Governor Kazuo Ueda has said the BOJ stands ready to continue tightening policy if it becomes convinced that underlying inflation - the broader price trend sustained by domestic demand - will stabilise around the 2% target.
At the same time, policy choices by the government have altered the near-term inflation profile. Various measures introduced to shield households from the burden of rising living costs - most notably fuel subsidies and a fresh curb on gasoline prices implemented this month - have weighed on measured consumer prices and made it harder for the BOJ to identify the persistent component of inflation.
Analysts cited those government interventions as a primary reason why core inflation is expected to remain below 2% in the coming months. With crude oil prices pushed higher amid the Middle East conflict and the yen trading weak - factors that tend to raise import costs - the subsidies are, in effect, offsetting some of that upward pressure.
Officials and analysts estimate the gasoline price curb introduced this month could reduce the year-on-year core CPI by as much as 0.5 percentage point, demonstrating how targeted policy actions can materially alter headline readings.
To address the measurement challenge, Governor Ueda said last week the BOJ will publish by summer a new price indicator designed to strip out the impact of such one-off policy measures. Some market observers view the forthcoming indicator as a tool to better discern underlying inflation trends and, potentially, as part of the case for any future rate adjustments.
The interplay between government cushioning measures and externally driven cost pressures - namely crude oil and a weak currency - leaves the BOJ navigating a narrow path: judging whether domestic demand is producing sustained inflationary momentum, or whether recent readings reflect temporary interventions and volatile external factors.
Summary: Core consumer inflation in Japan eased to 1.6% in February, slipping below the BOJ’s 2% target for the first time since March 2022. A separate measure excluding both fresh food and fuel rose 2.5% in the year to February. Government fuel measures and surging oil prices tied to the Middle East conflict are imposing opposing effects on prices, complicating the central bank’s decisions on further rate hikes. The BOJ plans to publish a new price indicator by summer to remove one-off policy influences.
