I. Key Points
On October 22, international crude oil prices rose due to market concerns over the potential escalation of the US-Iran conflict and supply risks driven by Houthi attacks on Saudi Arabia. The NYMEX WTI crude oil December futures contract closed at $99.47/barrel, up $2.32/barrel from the previous session (+2.39%). The ICE Brent crude oil December futures contract closed at $113.17/barrel, up $4.35/barrel (+4.00%). China's INE crude oil futures (contract 2612) rose by 1.2 yuan to 702 yuan/barrel during the day session and increased by another 11.2 yuan to 713.2 yuan/barrel in the night session.
On October 22, the price of ethylene oxide (EO) in the key East China market stood at 9,700 yuan/tonne, unchanged from the previous period.

III. Market Outlook
Today, domestic polycarboxylate superplasticizer monomer prices are expected to remain firm or stable. The primary raw material, ethylene oxide (EO), is likely to maintain stability. Although margins for monoethylene glycol (MEG) have narrowed, prompting some co-production units to increase EO output, supply pressure remains manageable as previously shut-down units for maintenance have not yet resumed operations while downstream consumption proceeds steadily. Ethylene producers face insufficient available inventory for sale, showing little willingness to offer discounts, which supports a continuation of stable pricing trends; cost-side support may also persist. Within the monomer market, low-priced supplies are dwindling, and sellers exhibit strong price-holding intentions. Downstream users are engaging in small-volume purchases based on rigid demand, resulting in an overall subdued but steady trading atmosphere with transactions negotiated case-by-case. In summary, the EPEG price in the key East China market is projected to range between 10,000 and 10,400 yuan/tonne today.
