GYDI
Gold-Real Yield Divergence Index
DEFINITION
A composite index measuring the breakdown of the traditional gold-real yield inverse relationship. Higher scores indicate that gold is diverging from its expected behavior relative to real interest rates — suggesting structural forces (central bank buying, de-dollarization) are overriding the yield signal.
Components & Weights
Correlation Breakdown
Rolling correlation between gold and TIPS real yields vs. historical norm. Weakening correlation = traditional model failing.
Regime Deviation
Gold price deviation from the level implied by current real yields using the pre-2022 regression model.
Structural Override
Proxy for non-yield gold demand (central bank purchases, ETF flows) that explains the residual not captured by real yields.
Score Interpretation
| Score Range | Signal | Interpretation |
|---|---|---|
| 0–30 | Low Divergence | Gold tracking real yields normally |
| 30–60 | Elevated Divergence | Relationship weakening; structural forces emerging |
| 60–100 | High Divergence | Traditional model broken; regime shift underway |
