Bitcoin and Dollar Exhibit Unprecedented Inverse Relationship

The correlation between bitcoin and the Dollar Index has reached its most extreme level in nearly four years, with a 30-day correlation coefficient of -0.90. This indicates a strong inverse relationship, where a weaker dollar leads to bitcoin gains and vice versa. The coefficient of determination suggests that approximately 81% of bitcoin's short-term price movements are associated with changes in the Dollar Index. Bitcoin's recent rally has stalled, coinciding with a bounce in the Dollar Index. Broader macro risks, including elevated oil prices and the U.S.-Iran standoff, are expected to support the Dollar Index. Analysts believe that these factors will continue to pose a headwind for bitcoin's rally, with some predicting that a meaningful recovery may not occur until October or November. Meanwhile, sustained inflows into U.S.-listed spot exchange-traded funds are providing price support, but industry leaders remain cautious. The ether-bitcoin ratio has also fallen to its lowest level since March 15, confirming a downside break from its short-term ascending channel and pushing it back below the broader downtrend line. This breakdown is expected to lead to further underperformance of ether relative to bitcoin.
