#real-yields

The inflation-adjusted side of the US Treasury yield curve, served from the Treasury's official daily feeds. The realyields endpoint returns the latest TIPS real yield curve — the inflation-protected (real) yield at the 5, 7, 10, 20 and 30-year maturities. The breakeven endpoint returns market-implied inflation: at each maturity it takes the nominal Treasury yield minus the real yield, which is the average annual inflation rate the bond market is pricing in over that horizon, and returns it alongside the nominal and real components. The history endpoint returns the daily time series of the real yield, the nominal yield and the breakeven inflation rate for one maturity over a year. A 10-year breakeven of 2.3 means the market is pricing roughly 2.3% average inflation over the next decade — a core gauge for rates traders, macro funds and inflation hedgers. This is the real-yield and inflation-expectations data-cut — distinct from the nominal yield-curve, the world-government-bond and the central-bank-rate APIs in the catalogue. Live, no key on the upstream, nothing stored.
