Bitcoin faces a much stronger dollar
The DXY was still below 100 in early September. One month later, it has moved above 101.7—an increase of around 2% over 30 days and its highest level since May 2025.
This acceleration comes as Bitcoin is already weathering a spectacular rise in bond yields.
The U.S. 10-year Treasury yield is now around 5.3%, after reaching 5.34%, its highest level since 2002. Yields this high attract more capital to dollar-denominated assets and mechanically increase demand for the U.S. currency.
The euro is taking the other side of the move. It has fallen below $1.13 for the first time since May 2025 and reached a 17-month low. Sterling, the yen and several Asian currencies are also declining.
For crypto markets, the mechanism is fairly familiar: a stronger dollar generally reduces appetite for assets whose valuations depend heavily on global liquidity.
The DXY has not broken Bitcoin yet
Bitcoin’s reaction has nevertheless remained relatively contained.
BTC is trading around $83,700 to $84,000, after briefly moving above $85,500 on Wednesday when U.S. PCE inflation came in below expectations. The rebound quickly faded as bond yields remained close to their highs.
This is precisely the least comfortable combination for Bitcoin: a strong dollar and elevated real yields.
BrefCrypto had already examined this mechanism when U.S. interest rates and oil prices triggered a correction in the crypto market.
An investor can now earn more than 5% on certain Treasury maturities. The higher that yield rises, the greater the opportunity cost of holding a non-coupon-bearing asset such as Bitcoin.
But BTC is not collapsing.
After its second-best third quarter on record, Bitcoin remains around $84,000 and has even posted a slight gain over the past 24 hours. That resilience is all the more notable as the Nasdaq and European markets are also coming under pressure from high interest rates.
A strong dollar and Bitcoin are not always enemies
The relationship between the DXY and Bitcoin is often inverse, but it is not mechanical.
A strong dollar can weigh on BTC when it reflects tighter monetary policy. In that case, rates rise, liquidity declines and investors generally reduce their exposure to risk assets.
But the current backdrop has a second dimension.
The dollar is also rising because markets are concerned about debt, public deficits, inflation and the relative weakness of other major economies. Over the longer term, the same concerns could support Bitcoin’s narrative as a scarce monetary asset.
This is why elevated U.S. yields had already placed Bitcoin in a paradoxical position: a negative short-term signal, but an additional argument for those who view BTC as a hedge against monetary debasement.
The DXY, which ICE describes as an index measuring the dollar against a basket of currencies, is therefore becoming an indicator to watch closely.
A sustained move above 102 would probably increase macro pressure on risk assets. Conversely, a pullback in the dollar accompanied by easing yields could give BTC room to challenge resistance between $85,000 and $90,000.
For now, the picture is rather unusual: the dollar has just reached its highest level since May 2025, U.S. yields are at their highest since 2002, and Bitcoin is still holding around $84,000.
