Bitcoin and Dollar Display Near-Perfect Inverse Relationship, Reaching a 4-Year Extreme

The correlation between bitcoin (BTC) and the Dollar Index (DXY) has reached its most extreme level in almost four years, with a 30-day correlation coefficient of -0.90, indicating that when the dollar weakens, bitcoin strengthens, and vice versa. This inverse relationship is influenced by bitcoin's continuous trading structure. The coefficient of determination shows that approximately 81% of bitcoin's short-term price movements are associated with the Dollar Index. Bitcoin's recent rally has stalled after reaching highs above $79,000, coinciding with the DXY bouncing back to 98.75. The Dollar Index's outlook appears supported by broader macro risks, including elevated oil prices and the U.S.-Iran standoff. Analysts note that macro factors are leaning against bitcoin's continued rally, with sustained inflows into U.S.-listed spot exchange-traded funds (ETFs) providing some price support. Industry leaders remain cautious, with some predicting that bitcoin may not see a meaningful recovery until October or November, aligning with its four-year reward halving cycle. The ether-bitcoin (ETH/BTC) ratio has fallen nearly 3% to its lowest level since March 15, confirming a downside break from the short-term ascending channel and pushing the ratio below the broader downtrend line, which reinforces bearish momentum and increases the likelihood of further downside or extended consolidation in the ETH/BTC pair.
