Japan's ongoing disinflation is complicating the Bank of Japan's path for future interest rate hikes. Data released by the Ministry of Internal Affairs and Communications on Tuesday showed the Consumer Price Index (CPI) rose 1.3% year-on-year in February, the lowest rate since March 2022. This marks the fourth consecutive month of decline and a drop below the central bank's 2% policy target.
Simultaneously, core CPI, which excludes fresh food, increased by 1.6%, falling short of market expectations of 1.7% and dipping below the 2% target for the first time in nearly four years.
The slowdown in inflation is primarily attributed to government fuel subsidies. However, surging energy prices resulting from conflict in the Middle East present a new upside risk, creating greater uncertainty for the Bank of Japan as it assesses the inflation trajectory. Last week, the central bank maintained its benchmark interest rate at 0.75% while warning of inflationary risks stemming from the Middle East situation.
Core inflation falling below the target makes the timing of future rate hikes more difficult to determine. February's core CPI rose 1.6% year-on-year, down from 2.0% in January. This is the first time it has fallen below the Bank of Japan's 2% target since March 2022 and also missed economists' forecast of 1.7%.
The core-core CPI, which excludes both fresh food and energy, increased 2.5% year-on-year, a slight deceleration from 2.6% in January. This indicator is viewed by the Bank of Japan as a better gauge of domestic demand-driven inflation.
Analysis suggests that core CPI is expected to remain below 2% in the coming months due to the persistent effects of government fuel subsidies. The gasoline price control measures introduced by the government this month are estimated by analysts to potentially suppress core CPI by as much as 0.5 percentage points.
Bank of Japan Governor Kazuo Ueda has previously stated that the central bank would be prepared to continue raising interest rates if it becomes more confident that underlying inflation will stabilize near the 2% target. Last week, he also indicated that the bank plans to announce a new price indicator by this summer. This new metric would exclude the impact of one-off policy factors like fuel subsidies to provide a more accurate measure of underlying inflation trends—a move some analysts interpret as laying the groundwork for further rate hikes.
Government policies and energy shocks are exerting opposing influences on the inflation trend. Government intervention is a significant factor behind the cooling inflation. Campaign promises included a two-year suspension of an 8% food tax, and the government has implemented various measures, including fuel subsidies, to alleviate cost-of-living pressures for residents. While these actions have helped lower the inflation figures, they also make it challenging for the Bank of Japan to accurately assess the underlying inflation level.
The Bank of Japan had previously projected that the year-on-year increase in consumer prices could fall below 2% in the first half of this year due to these policies. The bank's forecasts for core CPI and core-core CPI for fiscal year 2026 are 1.9% and 2.2%, respectively.
Conversely, energy price shocks stemming from Middle East conflicts create opposing pressure. The Middle East conflict is described as a "disturbing surprise," with soaring commodity prices potentially triggering supply shocks and pushing inflation higher. For a major energy and food importer like Japan, this is unfavorable news. It was noted that if the conflict ends relatively quickly, the economic impact might be limited, but a prolonged conflict would have more severe consequences.
Sluggish economic growth further constrains the Bank of Japan's policy options. Data shows the Japanese economy grew a mere 0.1% year-on-year in the fourth quarter of last year, a significant slowdown from the 0.6% growth in the third quarter, narrowly avoiding a technical recession.
The Bank of Japan ended its decade-long ultra-loose monetary policy in 2024 and has raised interest rates multiple times, including a hike last December, citing steady progress toward sustainably achieving the 2% inflation target. However, the persistent decline in recent inflation data has made markets more cautious about predicting the timing of the central bank's next rate hike.
Ongoing government price interventions continue to distort inflation data, presenting greater challenges for the central bank in gauging the underlying inflation trend. Governor Ueda's initiative to introduce a new price indicator is seen by some analysts as an attempt to find clearer justification for rate hikes amidst significant policy-related noise.
