TOKYO, July 27 (Reuters) – Japan’s services producer price index ‌rose 3.2% in ‌June from a year earlier, central ​bank data showed on Monday, a sign of broadening inflationary pressure that will ‌keep alive ⁠market expectations for further interest rate hikes.

The annual ⁠rise in the index, which tracks the price ​companies charge ​each ​other for services, ‌followed a revised 3.4% gain in May.

The increase was driven by continued gains in transportation costs, which rose ‌5.3% in June ​from a ​year earlier, ​as rising fuel ‌prices and supply ​disruptions from ​the Middle East conflict kept ocean and air ​freight ‌charges elevated, the data showed.
