Real Federal Funds Rate — Daily CSV Download (Monetary Policy Stance)
The real Federal Funds rate — the overnight interbank rate minus CPI inflation — is the most direct measure of whether monetary policy is truly restrictive or accommodative. Negative real rates mean the Fed is subsidizing borrowing; positive real rates mean it is genuinely tightening. The real Fed Funds rate was deeply negative (−8%) in 2022 even at 0% nominal — because inflation was 9%. It turned positive only in late 2023.

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 nominal Fed Funds rate and the CPI inflation helps situate this indicator within the broader macro regime.

Methodology
Effective Federal Funds rate (FRED: FEDFUNDS) minus CPI YoY inflation (FRED: CPIAUCSL). This is the ex-post real policy rate — the most direct measure of how tight or loose the Fed actually is, as opposed to how tight it appears in nominal terms.
This dataset is updated monthly via automated pull from the FRED API.

The real Fed Funds rate is where the rubber meets the road for monetary policy. A 5% nominal rate with 5% inflation is neutral; with 2% inflation it is highly restrictive. This distinction explains why the same nominal rate can produce radically different economic outcomes.

Related Research
The real Fed Funds rate defines the policy regime. Combined with the real 10Y yield, it reveals whether the entire rate curve is restrictive or accommodative in inflation-adjusted terms.
