What to Watch
Drifting from pattern
Recent correlation (+57%) is running 1.0σ away from the long-run average of +21%.
Tighter in drawdowns
Pair moves more tightly when both fall (+56%) than when both rise (+20%) — typical risk-off behaviour.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
