Japan's core inflation accelerates for 4th month in August

Japan's core consumer inflation accelerated for the fourth straight month in August and tracked comfortably above the central bank's 2% target, data showed on Friday, keeping alive expectations for further interest rate hikes.

The data comes hours before the Bank of Japan concludes its two-day policy meeting, where it is widely expected to keep interest rates steady at 0.25%.

The core consumer price index, which excludes volatile fresh food costs, rose 2.8% in August from a year earlier, matching a median market forecast. It followed a 2.7% rise in July.

A separate index stripping away both fresh food and fuel costs, which is scrutinised by the BOJ as a better gauge of demand-driven inflation, rose 2.0% in August from a year earlier. In July, the index was up 1.9%.

"While the yen has strengthened sharply in recent weeks, we think it will take at least half a year for lower input costs to be passed on to consumer prices," said Marcel Thieliant, head of Asia-Pacific at Capital Economics.

"Accordingly, underlying inflation should remain around 2% over the coming months, prompting another rate hike by the Bank of Japan at its October meeting," Thieliant said.

The BOJ ended negative interest rates in March and raised short-term interest rates to 0.25% in July on the view inflation was on course to hit its 2% target in coming years.

BOJ Governor Kazuo Ueda has stressed the bank's readiness to raise rates further if inflation durably hits its target accompanied by solid wage growth.

Japan's core consumer inflation has exceeded the BOJ's 2% for well over two years as rising raw material import costs, due in part to the weak yen, prodded firms to hike prices.

In current projections made in July, the BOJ expects core consumer inflation to hit 2.5% in the year ending in March 2025 before slowing to 2.1% in fiscal 2025 and 1.9% in 2026.
