Business Cycle Index (Preliminary July 2026)

The page centers on the Business Cycle Index and brings together preliminary figures, series, base-year and comparison materials, a list of past overviews, and contact information. The preliminary figures and series are both presented as new information dated September 7, 2026. The preliminary figures section contains the “Preliminary Figures for July 2026,” along with its “Overview” and “Preliminary Materials,” while the series section lists long-term series, figures for individual series, and the contributions of individual series to the CI index.

The “Past Overviews” section distinguishes between “Past Overviews” and “Past Overviews (13th Revision).” For 2026, it provides overviews, preliminary materials, and revisions for each month from January through June. For 2025, 2024, 2023, 2022, and 2021, it lists the same types of materials by month from January through December.

The page structure allows users to review the preliminary materials and series data for July 2026 and trace overviews, preliminary materials, and revisions for past months by year and month. The source does not provide specific judgments such as an economic expansion or contraction, nor the statistical figures themselves; it primarily provides information about the materials and related resources.

The latest preliminary figures section contains “Preliminary Figures for July 2026” and provides an “Overview (PDF format: 403KB)” and “Preliminary Materials (PDF format: 1161KB).” The publication date is September 7, 2026.

The announcements section states that the 22nd Business Cycle Index Research Meeting was held on July 23, 2026, and that PDF materials on changes to the CI base year and related matters in the “Business Cycle Index” were published on June 26, 2023.
