Tokyo Inflation Gains Heat as January Rate Hike Expectations Build Around BOJ Policy Moves

Inflation in Tokyo surged in December, climbing to 2.4 percent as price pressures widened. With the Bank of Japan’s January policy meeting looming, markets are speculating on whether a further rate hike is on the horizon amid signs of steady economic progress.

Core Inflation in Tokyo Rises Amid Broader Price Pressures

Market expectations for an imminent interest rate hike are sustained by data showing that core inflation in Japan's capital city rose in December due to broader pricing pressures.

Some experts believe the Bank of Japan (BOJ) will raise short-term interest rates at its next policy meeting on January 23 and 24, and the data will be one of the elements that the BOJ examines at that meeting, Investing.com reports.

While most market analysts were expecting a 2.5% increase, the core consumer price index (CPI) in Tokyo, which does not include the highly variable cost of fresh food, up 2.4% year-over-year in December. It came after November's 2.2% year-on-year increase.

Demand-Driven Inflation Index Under BOJ’s Scrutiny

Following a 1.9% increase in November, the statistics indicated that another index that excludes fresh food and fuel expenses increased 1.8% year-over-year in December. The BOJ closely watches this index as a stronger indicator of demand-driven inflation.

To gauge the extent to which Japan is achieving the Bank of Japan's 2% inflation target—a condition for additional rate hikes—policymakers closely observe the Tokyo inflation data, which is seen as a leading indicator of national trends.

Tokyo Inflation as a Predictor of National Trends

In March, the BOJ halted negative interest rates and in July, it lifted the short-term policy rate to 0.25%, all because Japan was seen as making good progress towards its inflation target.

Interest rate hikes by Governor Kazuo Ueda are possible if the economy and prices follow the board's predictions.

Interest rates will be hiked to 0.5% by March of next year, according to a Reuters poll that was conducted earlier this month. Markets are more curious about when the Fed would boost rates—at its meeting on January 23–24 or at the rate review on March 18–19—following its decision to maintain rates unchanged this month.
