Crypto and FX: The 2025 Dollar Connection—Why Bitcoin Moves With Global Risk and USD Trends

The link between crypto—particularly Bitcoin—and significant foreign exchange (FX) pairs in 2025 is mostly based on the US dollar and worldwide liquidity levels. Rather than acting as a separate or substitute asset class, Bitcoin currently trades very like a high-beta risk asset, strongly connected to USD movements and risk attitude. With strong BTC sell-offs coinciding with periods of greater dollar and tighter liquidity, Bitcoin and the US Dollar Index (DXY) have developed a consistent negative link. Present research reveals the BTC-DXY correlation to be hovering between −0.5 and −0.6, and the effects of general liquidity indices like M2 have decreased, with real yields and the dollar currently influencing short-term crypto performance.

Often following the trend of "risk-on" FX pairs like EUR/USD, AUD/USD, and NZD/USD, Bitcoin. While these assets struggle during times of USD strength and rising interest rates, they often rise when the dollar declines and risk appetite rises. Notably, both Bitcoin and pairs like EUR/USD rise during weak-dollar regimes and de-risk when the dollar strengthens—particularly apparent during international macroeconomic shocks or significant central bank decisions, when the co-movement sharpens.

For traders, this implies that the crypto-FX link acts like a leveraged anti-dollar trade: weakness in the USD helps to increase both Bitcoin and key FX pairings; dollar rises trigger crypto drawdowns. Tracking the DXY, major FX pairings, and global rate expectations—particularly around Fed or ECB meetings—is therefore now critical for forecasting cryptocurrency movements and identifying chances for correlation trades or reversions. Under this system, interest rates and the dollar send more macro signals to Bitcoin than broad measures of global money supply.
