Linear products were affected by a slight increase in mid week futures, and traders’ quotes were slightly raised, but the trend of high and low pressure products was weak. On October 22nd, international crude oil futures saw a significant increase, rising more than 2%. The cost side supports the polyethylene market. There are still expectations of an increase in the supply side, and domestic production capacity continues to be deployed. In terms of maintenance, the domestic polyethylene plant suffered a loss of approximately 95500 tons during this cycle (October 17-23), a decrease of 7300 tons compared to the same period last week. The operating rate of agricultural film has increased compared to the previous period, but some factories have slowed down their follow-up on orders in the later stage, resulting in lower than expected demand. Production enterprises and traders are actively lowering prices to reduce inventory, resulting in a weak polyethylene market.
There is an expectation of an increase on the supply side; The demand for greenhouse film may improve as it enters the peak season. The increase in supply may exceed the increase in demand, and it is expected that polyethylene will remain weak.

According to the Commodity Market Analysis System of Shengyi Society, as of the 22nd, the price of ethyl acetate was 5493.33 yuan/ton, a decrease of 36.67 yuan/ton or 0.66% compared to the price of 5530.00 yuan/ton on October 15th. There have been no changes to the ethyl acetate plant, and the supply side is running steadily. Downstream demand is poor, and the raw material market is falling, resulting in a weak and downward adjustment of ethyl acetate prices.
Recently, domestic ethyl acetate facilities have mainly maintained their initial state, with little fluctuation in on-site production capacity utilization. With the rise in ethyl acetate prices, positive market news has gradually eased. Although the supply side has tightened, downstream demand for entering the market has not followed up significantly, and some manufacturers are generally accepting high prices. In order to maintain shipments, the focus of ethyl acetate transactions has shifted downwards. At the same time, upstream acetic acid prices have declined, and cost support has weakened, resulting in a weak operation of the ethyl acetate market.
In the future, downstream entry of ethyl acetate will follow up as needed, and the market trading atmosphere is relatively weak. However, the operating rate of on-site equipment is not high, which also supports the supply side. The market supply and demand game is expected, and the short-term price of ethyl acetate is expected to be weak and stable. In the future, specific attention should be paid to equipment fluctuations and downstream follow-up situations.

According to the Commodity Market Analysis System of Shengyi Society, from October 13th to 17th (as of 15:00), the price of methanol in the East China port market in China first increased from 2288 yuan/ton and then fell to around 2280 yuan/ton, with a price drop of 0.38% during the cycle, a month on month drop of 0.11%, and a year-on-year drop of 7.19%. Methanol in mainland China is experiencing a weak decline, with no external support for olefin production. Coupled with the accumulation of inventory by mainland enterprises, high supply is absolutely suppressing market prices, and the downstream purchasing atmosphere is not strong. The average price of methanol in the port market has strengthened, with a focus on actively reducing inventory.
As of the close on October 17th, the closing price of methanol futures on Zhengzhou Commodity Exchange has fallen. The main contract for methanol futures, 2601, opened at 2314 yuan/ton, with a highest price of 2318 yuan/ton and a lowest price of 2264 yuan/ton. It closed at 2272 yuan/ton in the closing session, a decrease of 24 yuan or 1.05% from the previous trading day’s settlement. The trading volume is 653713 lots, with a position of 1058725 and a daily increase of 19443.
On the cost side, the pattern of coal supply reduction and demand increase has become apparent, driving up coal prices and supporting a rebound in cost. The cost of methanol is influenced by favorable factors.
On the demand side, traditional downstream demand is flat, procurement mentality is cautious, enterprises actively ship, and market prices passively decline. Most downstream products are affected by methanol prices, and the demand for methanol is biased towards negative factors.
On the supply side, the overall loss of equipment exceeds the recovery amount, and the utilization rate of production capacity decreases. The supply of methanol is affected by favorable factors.
In terms of external trading, as of the close on October 16th, the CFR Southeast Asian methanol market closed at $324.5-325.5 per ton, down $1 per ton. The FOB US Gulf methanol market closed at 93.5-94.5 cents per gallon; The European FOB Rotterdam methanol market closed at 269.5-270.5 euros/ton, down 2 euros/ton.
The future forecast shows that mainland methanol enterprises and traders have a clear intention to ship, but the overall market supply may increase. Business Society’s methanol analyst predicts that the domestic methanol spot market will be consolidating and observing.

The price trend of the crude oil market has declined. As of the 16th, the settlement price of the December WTI crude oil futures contract in the United States was $56.99 per barrel, and the settlement price of the December Brent crude oil futures contract was $61.06 per barrel. The crude oil market is affected by negative factors. On the one hand, OPEC+has launched a new round of production increase of 1.65 million barrels per day, but the market is still concerned about the long-term risk of oversupply, and the crude oil market continues to decline; On the other hand, the easing of the situation between Israel and Palestine, coupled with weakened demand from the United States, has dragged down global economic and demand expectations due to US tariffs. In addition, the increase in US crude oil inventories has led to the end of the peak oil season in the United States, and the global economic outlook and oil demand are not optimistic, resulting in a rapid decline in international oil prices.
Due to insufficient cost support, the production of new facilities, and weak demand, coupled with negative factors, PTA prices have continued to decline since October. As of October 17th, the spot price of PTA in East China was 4381 yuan/ton, a decrease of 4.65% from the beginning of the month. The maintenance and restart of the equipment coexist, and the new equipment continues to increase its load. The overall operating rate of the industry is currently around 75%.
On the demand side, there is insufficient cost support momentum, and yarn factories are mainly cautious and cautious. As the e-commerce shopping festival approaches, the consumer atmosphere in the terminal clothing and home textile industry is gradually becoming stronger. However, weaving enterprises still have limited new and supplementary orders, and their performance is lukewarm. The comprehensive operating rate of chemical fiber weaving in Jiangsu and Zhejiang regions is around 64%.
Business analysts believe that there are still many uncertain factors such as tariffs, and the sentiment in the commodity market is suppressed. The loose supply and poor demand in the crude oil market have put pressure on the oil market, and the PTA price center continues to decline. In addition, the downstream lacks confidence in the market and has average purchasing enthusiasm, maintaining essential procurement. Therefore, the polyester staple fiber market lacks favorable drivers, and prices will continue to decline.

The market for anhydrous hydrogen fluoride is temporarily stable this week. According to the analysis system of Shengyi Society, as of October 16th, the benchmark price of hydrofluoric acid in Shengyi Society was 12666.67 yuan/ton, an increase of 6.74% from the end of September.

As of October 16th, the benchmark price of fluorite in Shengyi Society was 3675.00 yuan/ton, an increase of 1.80% compared to the beginning of this month (3610.00 yuan/ton). The sustained high price of fluorite provides strong cost support for hydrofluoric acid, and the hydrofluoric acid market remains stable.
Demand side: Downstream market demand is weak. The current pace of raw material procurement at high prices is relatively slow, coupled with a significant increase in enterprise operating rates. Some manufacturers are operating at high loads, leading to an increase in inventory and a loosening of their pricing mentality, with a focus on on-demand procurement. Overall, the demand side has weak support for hydrogen fluoride, and it is expected that the hydrogen fluoride market will remain stable in the later stage.
Market forecast: The high price of raw material fluorite supports the market supply, and the downstream willingness to accept high priced raw materials is weak. Procurement is mainly based on essential needs, and it is expected that the anhydrous hydrogen fluoride market will temporarily stabilize in the later stage. More attention should be paid to changes in market supply and demand.

The market sentiment is optimistic, and manufacturers have raised their prices one after another; The inventory pressure of raw material manufacturers is not high, and the price of acetic acid remains high and firm. The cost support of ethyl acetate is good; In terms of demand, downstream inventory consumption is mainly during the holiday period, and there is a demand for inventory replenishment after the holiday. The market news is mostly positive, and the trend of ethyl acetate market is strong and rising after the holiday.
In the short term, the supply of ethyl acetate remains favorable, with firm enterprise quotations as the main factor and continued support from the raw material market. It is expected that the ethyl acetate market will operate at a high level. In the long run, the price of ethyl acetate will increase significantly, and downstream may have resistance to high prices. In the future, specific attention should be paid to the trend of raw materials and downstream follow-up.
