Consumption Activity Index
The Bank of Japan’s Research and Statistics Department releases the Consumption Activity Index (CAI) monthly to assess private consumption, which accounts for about half of GDP. The index uses sales and supply-side data to measure short-term consumption trends.
The useful question is what changes for users, developers or buyers, and whether the announcement stays industry context or becomes something people can actually use.
The Consumption Activity Index (CAI) is published by the Bank of Japan to provide a timely assessment of private consumption, a key driver of GDP. The index aggregates data from sales and supply-side statistics to track monthly and quarterly trends. It includes nominal and real indexes, adjustments for travel balance, and breakdowns by goods and services categories. The Bank of Japan emphasizes the CAI’s role in informing macroeconomic judgments and business cycle assessments.
The CAI data are released at 2:00 p.m. on the fifth business day of each month, though the schedule may vary. The index is designed to meet diverse analytical needs, offering flexibility for researchers and policymakers. The Bank of Japan provides methodological details in research papers to ensure transparency. Users can access charts and data through the Bank’s official channels for research and analysis purposes.
The Bank of Japan notes that the CAI data and related charts are subject to unscheduled changes, revisions, or terminations without prior notice. Commercial reproduction or copying requires permission from the Research and Statistics Department. The Bank encourages proper attribution when quoting or reproducing the data to maintain accuracy and credibility.
The CAI serves as a tool for understanding short-term consumption trends, supporting the Bank of Japan’s broader economic monitoring. While the index is widely used for research, the Bank cautions users about potential data updates. The release schedule and data availability are subject to the Bank’s operational policies and may be adjusted as needed.
