PriceSeek analysis of ethylene glycol, bullish/bearish score: 2. The shutdown of a 380,000-ton-per-year unit in Saudi Arabia for maintenance until February has led to a reduction in global ethylene glycol supply, tightening supply in the spot market, which is favorable for price increases. Combined with ethylene glycol futures data (such as the closing price of the 2605 contract at 3,846 yuan/ton, up by 7), the open interest increased by 5,267, indicating market expectations of a supply shortage and the potential for further increases in futures prices, scoring as a significant positive +2. Diethylene glycol, bullish/bearish score: 2. The unit shutdown directly reduces diethylene glycol supply, creating an imbalance between supply and demand in the spot market, which is favorable for price increases. The supply disruption is expected to last until February, with spot prices projected to rise significantly, scoring as a significant positive +2.
