TOKYO, Aug 14 (Reuters) – Japan’s core consumer inflation likely accelerated in July from the previous month, as faster food ​price gains and cost pressures on energy ‌from the war in the Middle East pushed prices higher, a Reuters poll of economists showed.

The data would likely reinforce market expectations of an interest rate hike by ‌the ​Bank of Japan in September.

The ⁠nationwide core consumer price ⁠index (CPI), which includes energy items but excludes fresh food prices, was expected to rise 1.8% in July from a year earlier, a poll ​of 17 economists showed, accelerating for a second straight month from 1.6% in June but ⁠remaining below the BOJ’s ⁠2% target.

“Overall, the data are likely ​to suggest that the impact of the worsening situation ​in Iran is gradually beginning to feed ‌through to consumer prices,” said Ryosuke Katagi, a market economist at Mizuho Securities.

Japan’s annual wholesale inflation remained elevated at 7.2% year-on-year in July, highlighting ⁠broadening price pressures.

Beyond inflation concerns, joint Japanese-U.S. efforts to shore up the battered yen two weeks ago have ⁠heightened market bets ‌that the BOJ will need ⁠to hike rates faster and further, ​with another ‌move possible as early as next ​month. The ⁠BOJ raised interest rates to a 31-year high in June.

The internal affairs ministry will announce CPI data at 8:30 a.m. on Friday, August 21 (2330 GMT on August 20).
