Tokyo CPI Surge Fuels BOJ Rate Hike Trajectory as Underlying Inflation Accelerates

Tokyo CPI Surge Fuels BOJ Rate Hike Trajectory as Underlying Inflation Accelerates​

Japan's key inflation indicator picked up significantly for the first time in eight months, keeping the Bank of Japan (BOJ) on a trajectory to raise interest rates further. New data released on Friday from the Ministry of Internal Affairs and Communications shows that underlying inflationary pressures are building despite ongoing government relief measures.

The consumer price index (CPI) excluding fresh food rose 1.6% in June compared to the previous year in the capital. This reading was consistent with the median forecast among economists surveyed by Bloomberg. The overall CPI for Tokyo rose 1.7%.

Analysis of Key Inflation Gauges​

A critically watched measure that excludes both fresh food and energy saw a rise of 1.9%. This gauge, which provides insight into core inflation, climbed steadily. The advance in the CPI was partly attributed to fees for water services after subsidies were concluded.

Meanwhile, deflationary pressures from energy prices continued to subside thanks to gasoline subsidies implemented by Prime Minister Sanae Takaichi. However, these temporary reliefs are now being offset by other market trends.

Corporate Price Shifts and Weak Yen Impact​

The pickup in the CPI suggests that policymakers are concerned inflation might overshoot the BOJ's 2% target. While past readings were constrained by temporary government programs designed to lower living costs, this latest data provides support for the central bank's stance.

Businesses in Japan have begun showing a clear shift in their price-setting behaviors since the outbreak of the war in Iran. Instead of immediately cutting costs as they had before, several firms have started announcing price hikes, including Keihan Bus Co. and snack maker Kameda Seika Co.

Food Prices Trends and Service Demand​

Food price movements presented a mixed picture across Tokyo. Rice prices fell 6%, marking a reversal from the spike seen last year. Conversely, services—a key indicator of demand-driven inflation—rose by 1.1% from a year earlier, with lodging being one of the sectors leading this rise.

Taro Kimura, an economist at Bloomberg economics, stated that while the increase partly reflects water-fee waivers, "the underlying trend looks hot." He noted that firms are successfully passing on both higher labor costs and import prices inflated by the weak yen.

Policy Outlook and Market Vigilance​

The BOJ Governor Kazuo Ueda recently reiterated his strong stance to continue raising rates in response to current economic conditions and financial stability. Naoki Tamura, a hawkish board member, has specifically called for rate hikes every few months. The BOJ is set to announce its next policy decision on July 31.

Koya Miyamae, senior economist at SMBC Nikko Securities Inc., added that the "basic direction hasn't changed." He stated that if looking solely at the CPI excluding FX trends, he believes the BOJ is still on track for rate hikes at a cruising pace. The yen, hovering near the weakest level in nearly four decades, means traders remain highly vigilant over potential intervention from authorities.
