The Brave-Butters-Kelley Indexes (BBKI) are a research project of the Federal Reserve Bank of Chicago. The BBK Coincident and Leading Indexes and Monthly GDP Growth for the U.S. are constructed from a collapsed dynamic factor analysis of a panel of 500 monthly measures of real economic activity and quarterly real GDP growth.

The BBK Coincident Index is the sum of the leading and lagging subcomponents of the cycle measured in standard deviation units from trend real GDP growth.
