Bitcoin (BTC) and the US Dollar Index are moving in near-perfect opposition. The 30-day correlation between the two has deepened to -0.90, the most negative reading since 2022. A reading of -1.0 would mean the two assets move in exact opposite directions at all times.
What the Number Means
A correlation of -0.90 is close to a perfect inverse relationship. When the Dollar Index rises, Bitcoin falls, and vice versa. That pattern has held consistently across the past 30 trading days. At this depth, the two assets are rarely moving independently.
The Dollar Index, known as the DXY, tracks the dollar against a basket of six major currencies. It has weakened in recent weeks as trade tension and fiscal concerns weighed on sentiment. Bitcoin has moved higher over the same period.

Background
The last time the BTC-DXY correlation was this deeply negative was in 2022. That year saw sharp swings in both the dollar and crypto markets. The Federal Reserve began its most aggressive rate-hiking cycle in decades. Bitcoin fell from above $45,000 in January 2022 to below $17,000 by year-end. The dollar, by contrast, surged to a 20-year high. The inverse dynamic was pronounced through most of that cycle.
After 2022, the correlation fluctuated. There were stretches in 2023 and 2024 where Bitcoin and the dollar moved more independently. The current return to -0.90 represents a reassertion of the macro-linked pattern.

What Traders Are Watching
The depth of this correlation matters for portfolio positioning. Traders using Bitcoin as a dollar hedge are watching whether the -0.90 reading holds or extends further.
A reading at or near -1.0 would make Bitcoin one of the most reliable short-dollar instruments in liquid markets.
Macro traders have increasingly treated Bitcoin as a risk asset tied to dollar liquidity cycles. When the dollar weakens, global liquidity tends to expand. Bitcoin has historically benefited from those conditions. The current setup mirrors that logic closely.
No Federal Reserve meeting is scheduled in the immediate term. Upcoming US economic data releases, including GDP and PCE figures, could shift the DXY and test whether the Bitcoin correlation persists at this level.
