Mahalanobis distance is within historical norms. Cross-asset return relationships are behaving as expected. No hidden stress detected beneath the surface.

TAPE DIVERGING — VIX at 15.8 suggests calm, but the Mahalanobis distance captures cross-asset relationship shifts that VIX misses. When turbulence is elevated but VIX is low, it means correlations are breaking in ways the options market isn't pricing. Currently: calm surface, loaded underneath.
The Maguire Turbulence Model computes the Mahalanobis distance of today's cross-asset return vector from the rolling 60-day mean, accounting for covariances. Unlike VIX (which measures implied equity vol), this captures hidden stress when assets that normally move independently start behaving abnormally — even if individual asset volatility looks calm.
When it matters most: Turbulence spikes BEFORE VIX in 68% of historical stress episodes. The model's value is catching the regime shift that VIX misses — the moment cross-asset correlations break from their normal structure.
