January 9th News: On January 9th, a 380,000-ton/year ethylene glycol/diethylene glycol plant in Saudi Arabia was recently shut down for maintenance, which is expected to last until February. Chempricehub Analysis: Ethylene Glycol, Bull-Bear Score: 2. The shutdown of a 380,000-ton/year plant in Saudi Arabia for maintenance until February has led to a reduction in global ethylene glycol supply, tightening spot market availability, which is favorable for price increases. Combined with ethylene glycol futures data (e.g., the closing price of the 2605 contract at 3,846 yuan/ton, up by 7), and an increase in open interest by 5,267, indicating market expectations of a supply shortage, futures prices may rise further, scoring as a significant positive +2. Diethylene Glycol, Bull-Bear Score: 2. The plant 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 anticipated to rise significantly, scoring as a significant positive +2.
