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.

August 2019: The New York Fed Staff UIG Measures
  • The UIG “full data set” measure remains virtually unchanged from the previous month, at a currently estimated 2.6% in July.
  • The “prices-only” measure remains virtually unchanged from the previous month, at a currently estimated 1.9% in July.
  • The twelve-month change in the July CPI was +1.8%, a 0.2 percentage point increase from June.
-The UIG measures continue to estimate trend CPI inflation to be approximately in the 1.9% to 2.6% range.

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. For detailed information about our methodology, see the report and the references listed there.
The New York Fed Staff UIG measures are not official estimates of the Federal Reserve Bank of New York, its president, the Federal Reserve System, or the Federal Open Market Committee.
