The Consumer Price Index (CPI) measures the change in the price of goods and services purchased by households in Japan over a 12-month period. It is the key indicator for inflation and the primary tool used by the Bank of Japan to evaluate price stability. The index covers a wide range of categories including food, housing, and transportation. Persistent changes in CPI can lead to shifts in the central bank's interest rate policy and overall monetary stance.
Calculated by the Statistics Bureau of Japan using a Laspeyres formula, tracking a fixed basket of goods and services. The weights of the items in the basket are updated periodically to reflect current household expenditure patterns.
