Business Cycle Indicators

The material is organized into notices, preliminary reports, time series, criteria for trend assessment, comparisons of old and new seasonal adjustment models, a list of past summaries, and contact information concerning the Business Cycle Indicators. The preliminary reports provide a summary and preliminary materials for June 2026, while the time-series section provides long-term index data, figures for individual series, and materials showing the contributions of individual series to the CI index.

The notices include the 22nd Business Cycle Indicators Research Committee meeting, changes to the CI base year and other matters concerning the Business Cycle Indicators, information that figures from the preliminary report for January 2021 onward are those after the 13th revision, and implementation of the consumer sentiment questionnaire trial.

The time-series materials are divided into materials presenting the CI index, DI index, and cumulative DI index as long-term series, and materials presenting figures for individual series. The individual series figures are classified into leading, coincident, and lagging series, with each provided in Excel format. Materials on the contributions of individual series to the CI index are also provided for leading, coincident, and lagging series.
