Japan’s central bank issued a warning Monday that the country’s core inflation rate could experience heightened upward momentum from climbing oil costs and the weakening yen, as companies demonstrate increased willingness to implement price increases.
The Bank of Japan released this assessment as part of a research document examining elements that influence core inflation—price increases stemming from domestic consumer demand rather than external cost pressures—a fundamental metric the bank uses to guide decisions about interest rate adjustments.
According to the central bank, while recent crude oil price surges might negatively impact economic growth, they could simultaneously elevate public expectations about inflation and drive up core price levels.
“Attention is warranted to the possibility that upward pressure on prices through this channel may have strengthened compared with the past,” the bank stated, noting that businesses have adopted more aggressive approaches to increasing both prices and wages.
The research also indicated that evolving corporate pricing strategies could make inflation more vulnerable to yen depreciation, as the central bank cautioned about inflationary forces created when a weakened currency drives up costs for imported goods.
“Even temporary supply-side factors may affect inflation expectations,” the document warned, suggesting that ongoing increases in food costs could create sustained upward momentum in overall consumer price inflation if they continue.
Japan’s central bank concluded its decade-long massive economic stimulus program in 2024 and implemented short-term rate increases, believing the nation was approaching sustainable achievement of its 2% inflation goal.
Bank officials have indicated they will pursue additional rate increases if they gain greater confidence that core inflation will remain steady at the 2% level.
Addressing criticism from financial analysts who argued that the bank’s underlying inflation concept lacked clarity, the research paper detailed the institution’s measurement methodology.
Beyond examining the output gap, the central bank analyzes multiple price indicators, including a newly revealed index that excludes temporary elements such as government subsidies, while employing economic models to assess pricing trends, according to the document.
The bank also reviews various surveys to understand public sentiment regarding future price movements and develops proprietary composite indices, which currently show inflation expectations ranging between 1.5% and 2.0%, the paper revealed.
“Looking at factors underlying price developments, the output gap has been on an improving trend, albeit with some fluctuations. Labor market conditions remain extremely tight, and wages are rising moderately,” the document stated.
“Taking these points into account, it could be judged that the underlying inflation rate is rising moderately toward 2%,” it continued. “Going forward, from the perspective of sustainable and stable achievement of the price stability target, it will also be necessary to monitor whether underlying inflation becomes firmly anchored at around the 2% level.”
