2、 Market analysis
This week, the price of bromine has risen, and the reference price for bromine spot production in Shandong region is 29000-31000 yuan/ton. Due to weather and policy reasons, domestic bromine enterprises still have tight inventory and insufficient industry operating rates, but downstream enterprises have average purchasing enthusiasm. In terms of raw materials, domestic sulfur prices have been rising this week, with an average market price of 2901 yuan/ton at the beginning of the week and 3157.67 yuan/ton over the weekend. The price has increased by 8.85%, which is 114.48% higher than the same period last year. Downstream demand is generally average.
Prediction: Bromine prices are expected to rise recently, while upstream sulfur prices are expected to remain strong. Bromine prices are expected to remain strong this week, and downstream buyers are expected to purchase as needed, which may lead to resistance to the increase in bromine prices. Overall, it is expected that bromine prices will continue to remain strong in the future, depending on downstream market demand.

This week, the price of isooctanol fluctuated and fell
According to the Commodity Market Analysis System of Shengyi Society, as of October 20th, the price of isooctanol was 6283.33 yuan/ton, a fluctuating decrease of 4.07% compared to the price of 6550 yuan/ton on October 13th last Monday; Compared to October 1st, the price of isooctanol fluctuated and fell by 5.75% to 6666.67 yuan/ton. Partial maintenance of isooctanol equipment in some enterprises resulted in a slight decrease in the operating load of isooctanol facilities and a decrease in isooctanol supply; The price of propylene has fallen, and the cost of isooctanol has decreased; This week, the supply of isooctanol has decreased, coupled with a decrease in costs, causing the price of isooctanol to fluctuate and fall.
The cost of raw material propylene has decreased
According to the Commodity Market Analysis System of Shengyi Society, as of October 20th, the price of propylene was 6195.75 yuan/ton, a fluctuating decrease of 5.30% compared to the price of 6543.25 yuan/ton on October 1st. This week, the price of propylene fluctuated and fell, raw material prices fell, and the cost of isooctanol decreased, increasing the pressure on the price of isooctanol to decline.
Downstream plasticizer DOP prices fluctuate and fall
According to the Commodity Market Analysis System of Shengyi Society, as of October 20th, the DOP price was 7209.17 yuan/ton, a fluctuating decrease of 2.15% compared to the DOP price of 7367.50 yuan/ton on October 1st; Compared to October 13th, the DOP price of 7309.16 yuan/ton fluctuated and fell by 1.37%. This week, DOP prices have fluctuated and fallen, with DOP companies operating at less than 60% capacity, resulting in a decrease in operating rates and DOP production. The demand for isooctanol has also decreased, leading to significant downward pressure on isooctanol prices.
Future expectations
The data analyst of Business Society’s octanol product believes that in terms of cost, the price of propylene has fallen, the price of raw materials has fallen, and the pressure of isooctanol’s decline has increased. In terms of demand, DOP prices have fluctuated and fallen, while DOP companies have seen a slight decrease in production, resulting in a decrease in DOP output and reduced support for isooctanol demand. In the future, the demand for cost reduction of isooctanol is weak, and the downward pressure on isooctanol is increasing. It is expected that the price of isooctanol will fluctuate and fall in the future.

According to the Commodity Market Analysis System of Shengyi Society, from October 13th to 17th, the domestic ethanol price was 5550 yuan/ton, a month on month decrease of 1.46% and a year-on-year decrease of 0.54%. The price of raw corn has significantly decreased, with some areas experiencing an increase in plant production after the holiday. Downstream demand for replenishment has also increased, resulting in low transaction prices. The price of ethanol in the domestic market has also dropped significantly.

On the cost side, corn prices continue to show a weak trend overall. Many areas in North China have once again experienced rainy weather, with most grassroots grain points in a state of suspended harvesting, and market purchases and sales being sluggish,. The cost of ethanol is influenced by bearish factors.
On the supply side, multiple previously shut down enterprises have recently produced by-products, and the ethanol supply side is affected by negative factors.
On the demand side, downstream procurement is mainly based on demand. Negative factors affecting ethanol demand.
Market forecast shows an increase in supply and a need for recovery in demand. The ethanol analyst from Shengyi Society predicts that the short-term ethanol market will be mainly weak.

Since September, asphalt prices have been fluctuating downwards due to various factors. According to monitoring data from Shengyi Society, the ex factory price of heavy-duty asphalt # 70 in Shandong region was 3680 yuan/ton on September 1st, and as of September 29th, the ex factory price in Shandong region was 3593 yuan/ton.
In September, the supply of raw materials was abundant, and most local refineries maintained a high level of production enthusiasm, driving the overall asphalt production to increase compared to last week. Last week, the capacity utilization rate of 92 asphalt refineries in China was 42.0%, an increase of 5.7% compared to the previous week. The weekly asphalt production was 701000 tons, an increase of 15.5% compared to the previous week. Recently, competition for various brand resources remains fierce, and the pressure on asphalt supply remains high and difficult to reduce. It is expected that the planned production of asphalt in October will remain high, with a total domestic asphalt production of 2.682 million tons in October.

In terms of demand, some regions in China experience concentrated rainfall and typhoon weather, which hinders terminal demand. The national demand for asphalt shows a pattern of strong demand in the north and weak demand in the south. Due to the increase in supply and the suppression of demand by rainfall, the accumulation of inventory in Shandong region is more obvious. 104 domestic asphalt companies have a total social inventory of 154.1 tons. In the Northeast region, due to the narrowing of construction windows and price reductions by traders, the price advantage of social inventory resources has become apparent. Coupled with the support of rush work demand, the process of destocking has accelerated.
From the perspective of Shengyi Society, the fourth quarter has seen a significant increase in asphalt production recently, which may cause significant pressure on prices after the peak season ends and break the relatively strong pattern among asphalt consumers. Therefore, we hold a bearish view on asphalt prices in the fourth quarter.

The Jin Jiu market fell short of expectations, and the overall domestic acetone market continued to decline, currently reaching a new low for the year. The East China acetone market reported an average daily price of 4525 yuan/ton from September 1st to 4408 yuan/ton on September 29th, a decrease of 2.58%. From the perspective of the national acetone market, there are fluctuations of the same magnitude.

From the supply side, regardless of the manufacturer’s phenol ketone unit, there were different durations of shutdowns and maintenance during the month. As a result, the operating rate of phenol ketone units in China decreased to a low point of 66%. The supply of goods under import contracts has arrived in succession, especially the supply of goods from Saudi Arabia has been significantly supplemented. The supply of goods from South Korea, Taiwan, China, China, and Singapore has also been supplemented in succession, while the supply of goods from Thailand may be reduced.
From the demand side, it is expected that the operating rate of downstream bisphenol A plants will increase, and the demand for acetone will also increase; The operating loads of isopropanol, MMA, and MIBK have slightly changed, while the demand for acetone has not changed significantly. From a cost perspective, there has been a slight increase in both the supply and demand of raw material pure benzene, and the supply continues to be lower than demand. It is expected that the short-term price will strengthen and consolidate.
In September, the cargo volume of acetone in East China was 44000 tons, of which 35200 tons have arrived, 3800 tons are in transit, and 2000 tons were in transit in October. From the perspective of shipping schedule, the subsequent import freight will mainly be sourced from South Korea, Saudi Arabia, and Thailand, with domestic sources also being supplemented.
Business Society expects that the pre holiday stocking of terminal factories will be basically completed, waiting for further clarification after the holiday. There are fewer trading days affected by holidays in October, which puts pressure on contract digestion. Supply has increased and demand has slightly increased. It is expected that the domestic acetone market will maintain a weak and volatile trend after the National Day holiday, and this year’s gold, silver, and silver prices will fall far short of expectations.
