On October 18, 2025, UN sanctions were reimposed on Iran after the European Union triggered a ‘snapback’ mechanism, effectively ending efforts to revive the JCPOA. This move could significantly influence geopolitical dynamics but has yet to produce noticeable effects on cryptocurrency markets. 2018’s U.S. withdrawal from the JCPOA led to market volatility, while no explicit disruptions were reported in crypto assets. This time, sanctions will likely trigger similar scrutiny, potentially increasing financial transaction oversight of Iran, although specific crypto regulations haven’t been implemented yet. The event signifies a pivotal shift in geopolitical dynamics. 2018’s JCPOA withdrawal showcased the potential for compliance pressures without direct crypto disruptions, as observed in Layer-1 assets. Experts suggest potential short-term market fluctuations based on historical data but are currently unsure of the long-term impact. The U.S. Treasury emphasized its commitment to counter Iran’s nuclear activities and malign influence. While the exact consequences remain unclear, monitoring the situation closely is crucial for investors.
