The DXY Dollar Index measures USD strength against a basket of six major currencies (EUR, JPY, GBP, CAD, SEK, CHF). Bitcoin historically has shown inverse correlation with DXY — when DXY rises (USD strengthens), BTC tends to underperform; when DXY falls, BTC tends to rally. The correlation is -0.3 to -0.6 rolling 90-day through most 2020-2026 periods. The logic: stronger USD = less need for alternative stores of value = lower BTC demand. But the correlation breaks during crypto-specific events (ETF approvals, halving cycles, exchange collapses). For allocators, DXY is a useful regime indicator — rising DXY is a headwind for BTC; falling DXY is a tailwind. Not deterministic but directional.
