Just Released: A Monthly Underlying Inflation Gauge

LSE_Just Released: A Monthly Underlying Inflation Gauge

Today marks the launch of the monthly publication of the Underlying Inflation Gauge (UIG). We are reporting two UIG measures, described recently on Liberty Street Economics, that are constructed to provide an estimate of the trend, or persistent, component of inflation. One measure is derived using a large number of disaggregated price series in the consumer price index (CPI), while the second measure incorporates additional information from macroeconomic and financial variables.

The trend component of inflation plays a critical role in many economic and financial decisions. Because this variable is not directly observed, researchers have proposed a number of approaches to estimate it. An attractive feature of the UIG is that it identifies sustained movements in inflation using information from a large data set. It has also shown more accurate forecasts of inflation compared with core inflation measures. More extensive discussion of the UIG’s design and usefulness for policymakers, market participants, and the public can be found in a new article in the New York Fed’s Economic Policy Review as well as in this staff report.

The monthly publication will feature a chart depicting the behaviors of CPI inflation and the UIG measures, and will include commentary and various summary points relating to the statistical framework and methodology employed. For those interested in using the inflation gauge for analysis, we are excited to announce that we will post spreadsheet data containing the values of the UIG measures, with estimates going back to 1995. In addition, we will begin to archive the corresponding report and spreadsheet data set for each monthly release.

The UIG measures will be estimated after the monthly release of the CPI report from the U.S. Bureau of Labor Statistics and will be posted that afternoon at 2:30 p.m.—subject to restrictions on communications during blackout periods surrounding Federal Open Market Committee meetings. When such restrictions apply, we will post the UIG measures on the first morning following the end of a blackout period at 7:00 a.m. (which will typically be a Friday). The UIG web page on the New York Fed’s public website provides a publication schedule for the monthly reports.

While this analysis is run on a daily basis internally at the New York Fed, we only share staff estimates on a monthly basis, according to the release schedule outlined on our website: The methodology is public, and described in our 2014 staff report “The FRBNY Staff Underlying Inflation Gauge: UIG” and our forthcoming Economic Policy Review article “The New York Fed Staff Underlying Inflation Gauge (UIG).” Find bibliographic detail in the References section of our downloadable monthly report. See also the Data Appendix on our website, which contains a complete list of the variables employed in the construct of our reported measures.

In another article written by same author, it is clearly indicated that by reporting frequency, there are 1 percent of UIG series is daily basis, therefore I assume that the UIG signal should be generated daily. However, I couldn’t find any related UIG reports other than the montly updates. Could FED post the daily signal onto the website? That would be really helpful. Kind regards
