December 25th – According to market rumors, a 500,000-ton-per-year ethylene glycol (EG) unit in Iran has been restarted. It is reported that the unit was shut down for maintenance at the end of November. Chempricehub analysis of ethylene glycol: Bull-Bear Score: -1. The restart of Iran's 500,000-ton-per-year EG unit increases market supply, exerting downward pressure on spot prices. The previous shutdown for maintenance had reduced supply, and the restart restores supply, potentially leading to a decline in spot prices. On the futures side, the main EG contract 2605 (closing price on December 24, 2025: 3,818 yuan/ton, up 59 points) has risen recently, but news of increased supply may curb future gains, posing a risk of a pullback in futures prices. Score: -1 (generally bearish), based on the moderate negative impact of supply increases on prices.
