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 August 10, 2017 update states the following:
The 2017–22 deflation probability was 5 percent on August 9, up from 3 percent on August 2. The 2016–21 deflation probability was 1 percent on August 9; it had been 0 percent from June 16 through August 2. These 2016–21 and 2017–22 deflation probabilities, measuring the likelihoods of net declines in the consumer price index over the five-year periods starting in early 2016 and early 2017, are estimated from prices of the five-year Treasury Inflation-Protected Securities (TIPS) issued in April 2016 and April 2017 and the 10-year TIPS issued in July 2011 and July 2012._________
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.
