US Treasury Real Yield Curve (TIPS)
The daily US Treasury real (TIPS) par yield curve - the 5, 7, 10, 20 and 30-year real yields the Treasury fits to Treasury Inflation-Protected Securities, in percent, 2003-present. The inflation-adjusted risk-free curve behind every real-rate, breakeven and macro model - subtract it from the nominal par curve for breakeven inflation. Tidied from the Treasury Atom-XML feed into one long-format Parquet.
