Bitcoin is trading near $63,900 and down nearly 1% since midnight UTC on Wednesday as the Dollar Index extended its gains to levels not seen in over a year, raising concerns among crypto traders that the world's largest digital asset could face further pressure.

Market Context

The Dollar Index (DXY), which tracks the U.S. currency's value against major fiat currencies including the euro, yen, and British pound, has gained 0.26% to 100.66, extending Wednesday's 0.8% rise. The index is now trading above a key level where sellers have consistently overpowered buyers since May 2025, resulting in prolonged sideways consolidation. The broader crypto market is mostly showing similar losses, with the exception of a few tokens such as HASH, XLM and ENA, which gained 7% or more during the session.

Analysis

What's notable is that DXY is on the verge of firmly breaking out of a 13-month-long trading range—a technical setup that usually leads to momentum chasing by traders, resulting in further gains. Strength in the greenback typically weighs on dollar-denominated assets such as bitcoin. BTC has historically tended to move in the opposite direction to the dollar, and its 90-day correlation coefficient with the DXY was recently minus 0.82, indicating a strong inverse relationship.

The greenback is clearly benefiting from the hawkish tone struck by the Federal Reserve on Wednesday, which has raised concerns that interest rates may rise in the U.S. New Fed Chair Warsh overhauled how the central bank communicates, trimming the policy statement and declining to submit a rate forecast of his own while launching five task forces to study everything from how the Fed communicates to how it analyzes the economy.

Should DXY continue to gain ground following a confirmed breakout above its trading range, BTC is likely to remain under pressure. Analysts expect bitcoin to stay range-bound between $60,000 and $70,000 absent a major catalyst, but the risk skews lower if the dollar strengthens as expected.

Key Numbers

- Bitcoin price: Near $63,900, down nearly 1% since midnight UTC

- Dollar Index (DXY): Up 0.26% to 100.66, extending Wednesday's 0.8% rise

- BTC-DXY 90-day correlation coefficient: Minus 0.82

- Bitcoin 200-week simple moving average: $62,258

- DXY key resistance level: Above 100.60 since May 2025

What to Watch

Traders should monitor whether DXY confirms a decisive breakout above its 13-month trading range consolidation, which could trigger accelerated momentum buying and further strength in the U.S. currency. Economists at crypto exchange Kraken note that dips below bitcoin's 200-week SMA have historically produced a median return of over 100% in one and three years—suggesting the level at $62,258 remains a critical support zone worth defending.

On the macro front, Fed Chair Warsh's new communication approach and any signals about future rate decisions will be closely watched. Additionally, the Iran-U.S. initial agreement to end their conflict—which commits both parties to achieving a final deal within 60 days—could impact oil markets and global risk appetite in the coming weeks.
