What to Watch
Unusual right now
Recent correlation (-46%) is 3.8σ from the long-run average of +92% — pair is behaving differently than usual.
Tighter in drawdowns
Pair moves more tightly when both fall (+68%) than when both rise (+46%) — typical risk-off behaviour.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
