What the Number Means

The 0.53 correlation indicates that WTI Crude Oil (FRED Daily) and 10Y Breakeven Inflation have a moderate tendency to move together. The relationship is real but noisy, with frequent days where they disagree. Regime context matters: the correlation often strengthens during stress and weakens during calm periods.

Recent vs Long-Run Behavior

Last 90 Days
+0.535
5-Year Baseline
+0.336

The correlation has strengthened materially. The 90-day reading of 0.53 is 0.20 above the long-run average of 0.34. Rising correlation typically accompanies deleveraging, broad risk-off, or a dominant single-factor regime where idiosyncratic drivers get drowned out.

Observations252

Correlation measures directional co-movement; R² quantifies the fraction of variance explained by the linear relationship. Beta is the slope coefficient from regressing WTI Crude Oil (FRED Daily) returns on 10Y Breakeven Inflation returns. A beta above 1 means the first asset amplifies moves of the second.

Extremes in rolling 90-day correlation often coincide with regime changes, forced deleveraging, or the arrival of a dominant new macro theme that overwhelms normal relationships.

Methodology

Correlations are computed on daily log-adjacent returns for WTI Crude Oil (FRED Daily) and 10Y Breakeven Inflation, aligned on shared trading dates. We use the Pearson product-moment coefficient, which measures the linear relationship between two return series.

Windows are the most recent N observations for 30D, 90D, and 1Y (252 trading days); the 5Y figure uses all aligned data up to 1,260 observations. Beta is the OLS slope from regressing the first series on the second. Data updates daily with a 24-hour revalidation cadence.

Correlation is not causation and backward-looking statistics can fail when regimes shift. Positions sized on historical correlation assumptions should be stress-tested against scenarios where the relationship breaks. For informational purposes only.
