Japan’s Corporate Services Price Index (CSPI) inched up to 2.7% year-over-year, slightly above the previous reading of 2.6%, according to data updated on 25 March 2026. The indicator compares the price change for the latest month with the same month a year earlier, highlighting ongoing cost pressures in the country’s service sector.
The modest acceleration suggests that service providers in Japan continue to pass on higher costs, reinforcing a broader trend of persistent, if measured, inflation. For policymakers and markets, the uptick in CSPI will be watched closely as it feeds into the wider debate over the durability of Japan’s price gains and the future direction of monetary policy.
