TOCI

Treasury-Oil Crosswind Index

DEFINITION

A composite index quantifying the tension between oil-driven inflation expectations and recession-driven yield compression. Higher scores indicate stronger crosswinds — meaning oil and Treasury markets are sending contradictory macro signals.

Components & Weights

35%

Yield-Oil Divergence

Directional mismatch between crude oil price moves and 10Y Treasury yield moves. Divergence = conflicting inflation/growth signals.

30%

Breakeven Stress

Deviation of TIPS breakeven inflation from its 6-month average. Rapid moves signal inflation expectation instability.

20%

Curve Signal

Treasury yield curve shape (2s10s spread) relative to oil price direction. Inversion + rising oil = maximum crosswind.

15%

Macro Context

ISM Manufacturing PMI relative to 50 threshold. Below 50 + rising oil amplifies the stagflationary crosswind signal.

Score Interpretation

Score Range Signal Interpretation
0–30 Low Crosswind Oil and yields moving consistently; macro signals aligned
30–60 Elevated Crosswind Conflicting signals building; watch breakevens
60–100 High Crosswind Severe macro contradiction; stagflation risk elevated
