TOKYO, Sept 18 (Reuters) – Japan’s core consumer inflation held steady near the central bank’s 2% target in August, data showed on Friday, highlighting mounting price ​pressures that solidify the case for a near-term interest rate ‌hike.

The data came hours before the Bank of Japan concludes its two-day meeting later on Friday, when it is widely expected to raise interest rates to a 31-year high of 1.25%.

The core consumer price index (CPI), which excludes volatile fresh food ‌but ​includes fuel costs, rose 1.7% in August ⁠from a year earlier, data ⁠showed, compared with a median market forecast for a 1.8% gain. It followed a 1.8% rise in July.

An index that strips away the effects of both volatile fresh food and fuel, which ​is closely watched by the BOJ as a better gauge of demand-driven price pressures, rose 1.9% in August from a year earlier.

Core ⁠inflation has stayed below the BOJ’s 2% ⁠target for eight straight months, as government subsidies aimed ​at curbing utility bills offset price hikes for a broad range of ​goods.

But rising fuel costs from the Middle East conflict and ‌higher import prices from a weak yen have added price pressure to the economy, prodding warnings from the BOJ of the risk of an inflation overshoot.

The BOJ raised interest rates to 1% in June ⁠on the view Japan was on the cusp of durably hitting its 2% inflation target. It kept rates steady in July but signalled a strong ⁠chance of a near-term ‌hike on mounting price pressures.

Sources have told Reuters ⁠the BOJ is set to raise interest rates ​this week ‌and may signal faster future tightening if price ​pressures heighten ⁠the chance of underlying inflation deviating from its 2% target.

Analysts polled by Reuters expect the BOJ to hike rates to 1.25% on Friday, 1.5% by end-March next year and then to 1.75% in the second quarter of 2027.
