The US dollar index (DXY) has rallied above 100, and has now gained over 5% from its January 2026 low. A popular narrative among investors is that a stronger dollar can be bad for bitcoin. But over the past ten years, that link has been looser than many assume. Here’s why a rising dollar doesn’t necessarily have to sink the bitcoin price.
Can a rising dollar be bad for bitcoin?
In theory, yes it can. Here are three reasons why:
1. Flight to safety: the dollar tends to attract money when investors turn nervous. In a general market sell-off, they often sell riskier assets and move into the dollar. Bitcoin can be one of the first investments they sell, given its volatility. So when fear is driving up the dollar’s value, bitcoin may fall at the same time.
2. Liquidity: the dollar often strengthens when money gets tighter. That usually happens when the US Federal Reserve keeps interest rates high. When rates are high, cash and bonds pay investors a higher yield to sit on the sidelines. That can make a volatile asset with no yield (like bitcoin) harder to hold.
3. Pricing: bitcoin trades in US dollars. People buy and sell it against the dollar on exchanges worldwide, at every hour. So when the dollar gets stronger across the board, bitcoin often shows a lower dollar price at the same time. That's less about people selling bitcoin, and more about the dollar gaining against everything else – bitcoin included.
But is a rising dollar always bad for bitcoin?
Not according to history. The chart below plots bitcoin (orange) against the DXY (blue) over the past decade. The DXY tracks the dollar's overall strength against the euro, pound, yen, Canadian dollar, Swedish krona, and Swiss franc.
The lower pane tracks their rolling correlation over a 26-week window. A reading near +1 means they tended to move the same way week to week, while one near -1 means they usually moved in opposite directions.
That correlation line has moved all over the place over the period. For example, it sank deep into negative territory in 2022, when the dollar spiked and bitcoin lost more than half its value. Yet it flipped positive in 2016, 2019, and 2024 – where both bitcoin and the dollar climbed together.
So on its own, a rising dollar isn’t always historically bad for bitcoin.
What it means for bitcoin
We've previously made the case that the $60,000 region looks like a potential value zone for bitcoin – the general area where a long-term low could form. Bitcoin has since found some buyers around that level. So far, our view hasn’t changed.
According to the correlation data, a rising dollar doesn't have to change that view, either. The level worth watching for bitcoin comes from its own chart and support levels, not from the dollar index.

Key takeaways
The US dollar index has rallied above 100. Investors often see a rising dollar as bad for bitcoin.
But over the past ten years, the link has been loose. Bitcoin and the dollar have moved both together and apart, so a rising dollar isn't reliably bearish for bitcoin.
The level worth watching for bitcoin comes from its own chart and support levels, not from the dollar index.
