Japan’s Inflation Edges Higher in October as BOJ Faces Growing Pressure to Hike Rates

Japan’s inflation rose slightly in October, reinforcing expectations that the Bank of Japan (BOJ) may soon move toward tightening its ultra-loose monetary policy. Government data released Friday showed that national core CPI, which excludes volatile fresh food prices, climbed to 3% year-on-year, up from 2.9% in September and in line with market forecasts. Headline inflation also increased to 3%, signaling that price pressures remain persistent across the economy.

A key measure closely monitored by the BOJ — core inflation excluding both fresh food and energy — rose to 3.1% from 3% in the prior month. This reading remains well above the central bank’s 2% target, suggesting that underlying inflationary forces remain strong. Food prices have been a major contributor to this persistent inflation, driven by poor harvests, notably in rice, and rising global grain costs that have pushed up domestic prices throughout the year.

Japan’s sharply weaker yen, which recently touched a 10-month low, has further fueled inflation by raising the cost of imported goods. Higher import bills have amplified overall price increases, making it more challenging for households and businesses already grappling with elevated food and commodity costs.

The continued stickiness in inflation is increasing the likelihood of a BOJ rate hike, with a recent Reuters poll showing that a slim majority of investors expect a move as early as December. This pressure may outweigh the central government’s preference for maintaining accommodative financial conditions, particularly under new Prime Minister Sanae Takaichi. Known as a fiscal dove, Takaichi is expected to ramp up government spending to stimulate the economy. Her election triggered significant weakness in the yen as markets questioned how her administration would finance expanded fiscal initiatives.

As Japan navigates rising prices, a soft currency, and shifting political priorities, investors are watching closely to see whether the BOJ will finally pivot away from its long-standing ultra-easy stance.
