Ethereum fell 1.5% to about $2,665 on Sep. 28 as oil prices rose after a setback in US-Iran talks. Reuters reported that oil rebounded on Monday after President Donald Trump rejected Iran’s latest proposal to resolve the conflict and reopen the Strait of Hormuz. Ethereum and the broader crypto market declined alongside the oil move. $ETH stayed above its daily moving averages (average prices over selected periods), while its four-hour chart indicated weak trend strength below $2,700. Binance daily-chart data showed Ethereum opening at $2,688.65, reaching $2,703.51 and dropping to $2,635.69. It traded near $2,661 when the TradingView chart was captured, leaving $2,700 as the nearest recovery level for buyers and marking Monday’s low as the first test below $2,650.
