Notes

This series is a measure of expected inflation (on average) over the five-year period that begins five years from today. This series is constructed as: (((((1+((GS10-FII10)/100))^10)/((1+((GS5-FII5)/100))^5))^0.2)-1)*100 where GS10, FII10, GS5, and FII5 are the 10 year and 5 year nominal and inflation adjusted Treasury securities. All of those are the actual series IDs in FRED.	2014-05-16	2019-06-20
