Underlying Inflation Gauge (UIG)

The UIG captures sustained movements in inflation from information contained in a broad set of price, real activity, and financial data.

September 2023: The New York Fed Staff UIG Measures
  • The UIG "full data set" measure for August is currently estimated at 3.0%, a 0.1 percentage point decrease from the current estimate of the previous month.
  • The "prices-only" measure for August is currently estimated at 2.3%, the same value as the current estimate of the previous month.
  • The twelve-month change in the August CPI was +3.7%, a 0.5 percentage point decrease from the previous month.
-For August 2023, trend CPI inflation is estimated to be in the 2.3% to 3.0% range, a slightly narrower range than July, with a 0.1 percentage point decrease on its upper bound.

UIG Measures and 12-Month Change in the CPI
Data Series
The “prices-only” underlying inflation gauge (UIG) is derived from a large number of disaggregated price series in the consumer price index (CPI), while the “full data set” measure incorporates additional macroeconomic and financial variables. For a list of the series employed, see the data appendix.

About the UIG
We share two monthly estimates of trend inflation. The first derives a measure from a large number of price series in the consumer price index (CPI) as well as macroeconomic and financial variables; the second employs the prices-only data set.
