The Underlying Inflation Gauge (UIG) provided estimates of the trend, or persistent, component of inflation dating back to 1995. It included a “prices-only” measure, where the data series used included only the subcomponents of the consumer price index (CPI), and a “full data set” measure, where the series included the CPI subcomponents as well as a range of macroeconomic and financial variables. The design of the UIG was first detailed in a 2014 Staff Report
. The product, updated monthly, was launched in 2017 as a PDF that included a chart and brief commentary, as well as a downloadable data file. It was relaunched as an interactive feature in 2021.
For more information on the UIG and the calculation of the two measures, see this Liberty Street Economics post
