The breakeven inflation rate represents a measure of expected inflation derived from 20-Year Treasury Constant Maturity Securities (BC_20YEARM) and 20-Year Treasury Inflation-Indexed Constant Maturity Securities (TC_20YEARM). The latest value implies what market participants expect inflation to be in the next 20 years, on average. Starting with the update on June 21, 2019, the Treasury bond data used in calculating interest rate spreads is obtained directly from the U.S. Treasury Department (https://www.treasury.gov/resource-center/data-chart-center/interest-rates/Pages/TextView.aspx?data=yield).

The Federal Reserve Bank of Cleveland estimates the expected rate of inflation over the next 30 years along with the inflation risk premium, the real risk premium, and the real interest rate. Their estimates are calculated with a model that uses Treasury yields, inflation data, inflation swaps, and survey-based measures of inflation expectations.
