Bitcoin and Ethereum fell Tuesday, Sept. 1, 2026, after U.S. Central Command confirmed that U.S. forces had begun striking Islamic Revolutionary Guard Corps targets in Iran near the Strait of Hormuz. CENTCOM said the strikes followed attempted IRGC attacks on commercial shipping in the waterway and American service members deployed to the region. The action followed Aug. 30 strikes linked to reported Iranian efforts to place mines in the strait. President Trump said the United States had retaliated for the attempted mining and for eight missiles fired at a U.S. military base in Jordan, and warned that any Iranian response would bring a larger attack. Brent crude rose to $96.70 a barrel, while the Dow Jones fell 401 points and the S&P 500 was 49 points lower. Gold dropped 2.35%, or $104, to $4,342 an ounce, and silver fell 2.86%, or $1.90, to $64.51. Bitcoin was initially reported 1.5% lower and later traded near the high-$76,000 range, down 2.5% over 24 hours, after recently reaching $82,207 and testing $76,984, its 0.786 Fibonacci support. Ethereum remained below $2,485, with support near its 20-day EMA at $2,308. Investors were awaiting Iran's response, while analysts continued to point to higher yields, fiscal deficits and crowded expectations for rising rates as risks to volatile assets.
