Tokyo Inflation Slows in May — Market Awaits Cautious Policy from Bank of Japan

According to data released by the Japanese government, consumer inflation in Tokyo slowed in May, reinforcing expectations that the Bank of Japan will proceed cautiously in its monetary policy tightening process.

Tokyo's core consumer price index (CPI), which excludes volatile food prices, rose 1.3% on an annual basis. This figure is lower than the 1.5% recorded in April and aligns with market forecasts.

Meanwhile, the index that excludes both food and energy prices remained flat month-on-month in May. The same measure rose 0.2% in April, indicating that inflationary pressures have somewhat eased.

Overall inflation also declined—Tokyo's consumer price index rose 1.4% year-over-year in May, compared to 1.5% growth in April.

Tokyo inflation data is often viewed as an important indicator of price trends at the national level. Although markets still expect the Bank of Japan to raise its policy rate from 0.75% to 1%, the slowdown in inflation provides policymakers with additional justification to proceed gradually and carefully.

Central bank officials have repeatedly noted in recent periods that overly rapid tightening is undesirable against the backdrop of uncertain global economic prospects and energy risks stemming from tensions in the Middle East.

Following the data release, the Japanese yen showed no significant change and traded at nearly unchanged levels against the dollar.
