The US dollar experienced sharp swings over two sessions, driven first by a blowout Nonfarm Payrolls report and then by renewed hopes for a US-Iran nuclear deal. These moves rippled through traditional currency markets and had immediate knock-on effects on Bitcoin and the broader crypto ecosystem, highlighting the inverse correlation between the greenback and digital assets.
NFP Data Sparks Dollar Surge
On Friday, the Bureau of Labor Statistics reported that the US economy added 336,000 jobs in September, more than double the consensus estimate of 170,000. The unemployment rate held steady at 3.8%, while average hourly earnings rose 0.2% month-over-month. The robust data reinforced expectations that the Federal Reserve will maintain its hawkish stance, with the CME FedWatch Tool showing the probability of a rate hike by December rising to roughly 30% from 20% before the release.
The dollar index (DXY) jumped, and the British pound broke below the psychologically important 1.3400 level against the dollar—its largest single-day decline in months. A stronger dollar typically weighs on risk assets, including cryptocurrencies. Bitcoin, which often moves inversely to DXY, faced immediate selling pressure, dipping below key support levels. Altcoins followed suit, with Ethereum and other majors posting losses as traders de-risked.
Geopolitical Shift Weakens the Dollar
By Tuesday, the narrative flipped. Unconfirmed reports of progress toward an interim US-Iran nuclear deal sent the dollar lower across the board. The prospect of lifted sanctions on Iranian oil exports raised expectations of increased global supply, which could bring down energy prices and reduce safe-haven demand for the greenback. DXY fell by around 0.4% in European trading, and GBP/USD reclaimed the 1.2700 handle.
The reversal provided immediate relief to crypto markets. Bitcoin rebounded from its lows, and the total crypto market capitalization recovered as risk-on sentiment returned. Ethereum and other altcoins saw even sharper bounces, reflecting their higher beta to liquidity conditions.
Implications for Crypto
The rapid swings underscore how macro events continue to drive crypto price action. A strong dollar, fueled by a resilient labor market, drains liquidity from risk assets and pressures Bitcoin. Conversely, any dollar weakness—whether from geopolitical de-escalation or dovish Fed signals—tends to catalyze a rally in digital assets. Traders should monitor upcoming inflation data and Fed communications for further clues, as the tug-of-war between rate expectations and geopolitical developments is likely to persist.
