Japan's core inflation in October held above the central bank's 2% target and an index stripping away the effect of fuel accelerated, data showed on Friday, keeping pressure on the central bank to raise its still-low interest rates.
The data also showed continued gains in service prices, which are closely watched by the Bank of Japan (BOJ) for clues on whether firms were passing on rising labour costs, suggesting conditions for further rate hikes were falling into place.
The readings will be among factors the BOJ will discuss at its next policy meeting on Dec. 18-19, when some analysts expect a hike in short-term rates to 0.5% from 0.25% as the central bank unwinds years of ultra-low rates.
The nationwide core consumer price index, which includes oil products but excludes fresh food prices, rose 2.3% in October from a year earlier, government data showed, slightly exceeding a median market forecast for a 2.2% gain.
It slowed from a 2.4% increase in September, mostly due to the base effect of last year's government decision to halve fuel subsidies that bumped up prices from October 2023.
A separate index that strips away the effect of volatile fresh food and fuel, scrutinised by the BOJ as a better gauge of demand-driven inflation, rose 2.3% in October from a year earlier, accelerating from a 2.1% gain in September.
Services inflation also perked up to 1.5% in October from 1.3% in the previous month, suggesting rising wages were prodding more firms to hike prices.
"All told though, the renewed strengthening of underlying inflation coupled with the recent rebound in consumer spending and the renewed weakening of the yen strengthen the case for another BOJ rate hike next month," said Marcel Thieliant, head of Asia-Pacific at Capital Economics.
The CPI data has drawn strong attention as many Japanese firms typically charge prices for services biannually in April, which is the start of the fiscal year, and October.
The yen and bond yields jumped on Thursday on expectations the BOJ could hike rates in December, after Governor Kazuo Ueda said the bank would examine a "vast amount of data and information" before the meeting.
The BOJ ended negative interest rates in March and raised its short-term policy rate to 0.25% in July on the view Japan was on the cusp of durably achieving its 2% inflation target.
Ueda has stressed the BOJ's readiness to raise rates again if Japan continues to make progress in durably achieving its price target backed by domestic demand and sustained wage gains.
