Real Yield (10Y)

What it is

Real Yield (10Y) — registry key real_yield.

Classifier metric. See the bands table below for the band-by-band reading.

Source

Source module: inflation
Data source: back_fillable

Fetched directly from app/sources/inflation.py; see source code for the upstream API call and any provider-specific handling.

How it’s computed

Raw 10-Year Treasury Inflation-Indexed Security (TIPS) yield from FRED series DFII10, in percentage points. The 10-year real yield is the nominal 10y Treasury yield minus 10y breakeven inflation — what investors earn after expected inflation, the canonical “real cost of money” for long-duration assets. Registry key is real_yield; the persisted column is real_yield_10y (registry field maps the two). Daily FRED publication. See app/sources/inflation.py:56 (_collect — _fetch_fred('DFII10')). The classifier bands (Accommodative / Neutral / Firm / Restrictive / Severely restrictive) are applied downstream via signal_defs.band_for('real_yield', value).
