While I do not agree with the current readings of the measure – I think the measure dramatically understates the probability of deflation, as measured by the CPI – the Federal Reserve Bank of Atlanta maintains an interesting data series titled “Deflation Probabilities.”
As stated on the site:
Using estimates derived from Treasury Inflation-Protected Securities (TIPS) markets, described in a technical appendix, this weekly report provides two measures of the probability of consumer price index (CPI) deflation through 2022.
A chart shows the trends of the probabilities. As one can see in the chart, the readings are volatile.
As for the current weekly reading, the December 20, 2018 update states the following:
Both the 2017–22 deflation probability and the 2018–23 deflation probability were 7 percent on December 19, unchanged from December 12. These deflation probabilities, measuring the likelihoods of net declines in the consumer price index over the five-year periods starting in early 2017 and early 2018, are estimated from prices of the five-year Treasury Inflation-Protected Securities (TIPS) issued in April 2017 and April 2018 and the 10-year TIPS issued in July 2012 and July 2013. The next deflation probabilities update is scheduled for January 3, 2019.
I post various economic indicators and indices because I believe they should be carefully monitored. However, as those familiar with this site are aware, I do not necessarily agree with what they depict or imply.
