The correlation between bitcoin's price and the Dollar Index has reached an extreme not seen in nearly four years, with a 30-day correlation coefficient of -0.90. This indicates a strong inverse relationship, where a weaker dollar tends to boost bitcoin's value, and vice versa.

However, it's essential to consider that bitcoin's 24/7 trading schedule can influence this correlation. The coefficient of determination suggests that around 81% of bitcoin's short-term price fluctuations are statistically linked to movements in the Dollar Index. Notably, bitcoin's recent rally has stalled, coinciding with the Dollar Index's bounce from its April 17 low.

Broader macro risks, including elevated oil prices and the U.S.-Iran standoff, appear to be supporting the Dollar Index's outlook. Analysts warn that these factors may continue to exert downward pressure on bitcoin's price. Despite sustained inflows into U.S.-listed spot exchange-traded funds, industry leaders remain cautious, with some predicting that a meaningful recovery may not occur until later in the year. 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 reinforcing bearish momentum.
