What this measures
Dollar-debasement alignment
When Bitcoin rises as DXY falls (negative correlation), it fits the classic "hard money hedge against a weakening dollar" narrative — often coinciding with rate-cut expectations or rising global liquidity.
Crypto-native divergence
When correlation is near zero, Bitcoin is trading on its own flows — leverage, narrative, on-chain activity — largely independent of the currency market.
Data source
DXY uses the ICE Dollar Index futures continuous contract via stooq.com, a free public daily-close feed with no API key. Bitcoin uses Binance BTCUSDT daily closes. Because DXY only trades on weekdays, this tracker aligns to shared calendar dates rather than reporting a 7-day BTC series.
