Download Real 10-Year Treasury Yield CSV (1962–2026) — Free Monthly Data
The real 10-year Treasury yield — nominal 10Y yield minus CPI inflation — is arguably the single most important variable in macro-finance. It determines the true cost of long-term capital, the discount rate for equity valuations, and the boundary between inflationary and deflationary monetary regimes. From +9.4% under Volcker (1982) to −6.4% during the 2022 inflation shock, this series spans the full spectrum of monetary history. FRED series GS10 minus CPIAUCSL since 1962.

Macro Takeaway
This indicator is a key component of the macro-financial monitoring framework. Its current level relative to its historical distribution — captured in the percentile and z-score above — provides immediate context for whether conditions are historically normal, stretched, or compressed.
Cross-referencing with the 10-year Treasury yield and the CPI inflation helps situate this indicator within the broader macro regime.

Methodology
Nominal 10-year Treasury yield (FRED: GS10, monthly average) minus CPI YoY inflation (FRED: CPIAUCSL). Regime classification follows five periods: Great Inflation, Volcker Shock, Great Moderation, ZIRP/QE, and Post-COVID normalization.
This dataset is updated monthly (15th of each month) via automated pull from the FRED API.
Historical Regimes
Historical regime analysis for this dataset will be added in a future update. The key stats block above provides immediate context for the current reading relative to the full historical distribution.
Related Macroeconomic Datasets
The real 10Y yield is the gravity of asset pricing. When real rates are deeply negative, every asset class is repriced upward; when they normalize, the entire valuation structure adjusts. This series is the foundation for regime-based analysis across equities, bonds, real estate, and commodities.
