GSW real (TIPS) curve + breakeven inflation
The Federal Reserve Board GSW real (TIPS) yield curve + breakeven-inflation curve for one day: real zero/par/forward at 2Y-20Y, breakeven inflation at 2Y-20Y, and the 5y5y real forward + 5y5y forward breakeven. Omit date for the latest published curve (weekly), or pass date (YYYY-MM-DD) for on or before. NOTE: a Fed staff research product, NOT an official statistical release. Breakevens include an inflation-risk premium and a TIPS-vs-nominal liquidity differential - they are NOT pure inflation expectations.
