A rising dollar poses less of a threat to bitcoin than many traders believe

The U.S. Dollar Index (DXY) is climbing, which is typically viewed as negative for bitcoin
DXY, which measures the dollar against a basket of major currencies including the euro and yen, has risen roughly 2.6% since September 9 and reached a two-month peak of 101.69 on Tuesday.
As the world’s reserve currency, the dollar sits at the heart of global finance and debt. When it strengthens, borrowers with dollar-denominated debt face higher repayment costs and typically reduce exposure to riskier assets. A weaker dollar produces the opposite effect.
In theory, a stronger dollar should pressure bitcoin. BTC’s rally has indeed paused since September 21, with prices retreating to the $83,000-$84,000 range from nearly $87,500. While a firmer dollar may be limiting gains, the impact so far has been modest.
Correlation data supports this resilience. Over the past 90 trading sessions, daily movements in BTC and DXY show a correlation of -0.41, based on TradingView data analyzed by Decryptnews. A negative reading indicates the two tend to move in opposite directions. This is the most negative correlation since February 2023.
However, while the relationship is real, it remains modest, as the featured chart illustrates. The correlation implies an R-squared of 0.17, meaning DXY explains only about 17% of the variation in BTC’s daily returns.
The shorter-term reading is noisier. The 30-day correlation stands at -0.45, but it’s heavily influenced by two sessions—August 19 and September 3—when BTC surged more than 5% as DXY declined. Excluding those days, the correlation falls to -0.19.
Zooming out further reveals an even looser connection. Since January 2020, the 90-day correlation has averaged -0.14 and has occasionally turned positive, peaking at +0.22 in November 2024.
Bitcoin also shows minimal notable correlation with U.S. Treasury yields, as Decryptnews discussed recently.
Combined with its weak link to the dollar, this bolsters the case for bitcoin as a portfolio diversifier—an asset driven largely by its own factors. Whether this independence persists bears watching. Stay alert!

Today’s signal
The chart displays the Dollar Index’s daily price movements in candlestick format.
The DXY is once again trading above the Ichimoku cloud, a momentum indicator, signaling strengthening bullish momentum. However, it has yet to break through immediate resistance at 101.80, the high reached on June 24.
A break above that level would signal a bullish resolution to the persistent sideways, choppy trading since May 2025, potentially accelerating gains.
