The Golden Nine Effect is not reflected in the downward trend of Shandong n-butanol market
From the commodity market analysis system of Shengyi Society, it can be seen that in September, the overall n-butanol market in Shandong, China, showed a fluctuating downward trend. In early September, the n-butanol market gradually declined, and the focus of market negotiations shifted towards lower levels. On September 12th, n-butanol fell to the lowest point of the month, with a price reference of 5916 yuan/ton. In mid September, there was little change in the market situation of n-butanol, and the fundamentals remained calm. The market entered a stable consolidation operation. In late September, the n-butanol market experienced a narrow correction, with a slight upward adjustment of 50 yuan/ton in the middle of the month. As of September 24th, the reference price for n-butanol market in Shandong region is around 5900-6000 yuan/ton.
Analysis of Market Factors
Supply side: Supply under pressure, shipment positive, market downturn
In September, the overall supply side of the n-butanol market in Shandong was relatively loose, and there was a certain supply pressure on the supply side. Some factories and suppliers actively shipped to maintain low inventory, but the supply side provided poor market support.
On the demand side: Downstream demand is cautious, and pre holiday stocking falls short of expectations
In early September, downstream demand for n-butanol showed caution, with downstream essential purchases being the main focus. The support from the demand side for n-butanol was weak, and as the end of the month approached, downstream users stocked up on a small scale before the holiday. Low level transactions of n-butanol improved, and the market situation slightly rose. Throughout September, the overall demand performance still fell short of expectations.
Future forecast
At present, the trading atmosphere in the n-butanol market is mild, with downstream users stocking up at low prices and still having a certain wait-and-see attitude towards high prices. The overall market situation is stable, and the n-butanol data analyst from Shengyi Society predicts that in the short term, the n-butanol market will mainly operate steadily with a moderate to strong trend. Specific attention needs to be paid to pre holiday market shipments and downstream stocking situation.

According to the Commodity Market Analysis System of Shengyi Society, as the end of September approaches, the domestic PP market is maintaining a weak and consolidated operation, with prices of various brand products falling more and rising less. As of September 23rd, the mainstream offer price for wire drawing by domestic producers and traders is around 6961.67 yuan/ton, a decrease of 3.04% compared to the price level at the beginning of September.
In terms of raw materials:
Since September, the geopolitical situation in Eastern Europe has remained relaxed, and market concerns about crude oil supply have decreased. At the same time, the OPEC+production increase strategy has continued to this day, coupled with a temporary decline in global demand and low fluctuations in international oil prices. In the early stage of propylene, the boost from Haiwei’s maintenance was exhausted, and there was sufficient supply of goods on site. The upward resistance in the market increased, and the price turned from high to low. Seasonal consumption of propane is on the rise, with prices remaining firm. Overall, the prices of PP raw materials have fluctuated, providing average cost support.
Supply side:
Recently, the operating rate of domestic PP enterprises has increased narrowly. As of press time, the overall load level of the domestic industry has been raised to around 76%, and the weekly average total output is around 770000 tons. The trend of loose supply in the future is clear, which severely limits the support from the supply side. The current on-site supply remains abundant, and the inventory level is significantly controllable at a high level of 800000 tons. Overall, the PP supply side has poor support for spot prices.
In terms of demand:
September is in the traditional peak season for polypropylene, and materials used in fields such as plastic weaving and agriculture have improved to a certain extent. There is also an increase in new orders in the field of packaging film materials, and the market momentum continues to rise. However, the positive trend of improved trading atmosphere in the current market has been smoothed out by many negative factors. In addition, downstream enterprises have a low workload and many National Day holidays are arranged, resulting in slow overall digestion, which has led to the failure of PP peak season consumption start-up and weak support for the demand side.
Future forecast
As September approaches the end of the month, the domestic PP market prices are still running weakly. Fundamentally speaking, the upstream raw material market is also weak, and the overall support for PP is insufficient. The industry load is expected to remain high with a narrow adjustment, and there are expectations of loose supply in the future. Although there has been an improvement in consumption, the market is being dragged by the cost and supply sides. There is no obvious peak season feature in the current market, and there is resistance to the PP upward trend. It is expected that the game may continue to consolidate the market.

Entering September, the overall trend of the domestic ABS market continued to consolidate and move weakly, with some spot prices of certain grades lowered. According to the Commodity Market Analysis System of Shengyi Society, as of September 22, the average price of ABS sample products was 9925 yuan/ton, with a price level increase or decrease of -1.73% compared to early September.
Fundamental analysis
Supply level: Since September, the domestic ABS industry has experienced a combination of load reduction and restart, with overall load being high, stable, and fluctuating. At the beginning of the month, due to the poor profit situation of the aggregation plant, some enterprises had cost maintenance operations, but the magnitude was relatively narrow. In the middle of the month, there is a return to production capacity in aggregation plants such as Tianjin Dagu. Based on recent short-term repairs by some manufacturers, the industry’s load level remains at around 70% with a narrow adjustment, and domestic plant dynamics have limited changes compared to the beginning of the month. The average weekly output is over 140000 tons, and the inventory position of the aggregation enterprise is at a high level of 240000 tons, with ample supply maintained on site. Overall, the long-term loose supply pattern in the ABS market remains unchanged, and industry inventory is relatively controllable. Overall, the supply side has weak support for ABS spot prices.
Cost factor: Recently, the upstream three material market of ABS has been generally weak, which has a negative impact on the cost side of ABS. At the beginning of the month, the supply of acrylonitrile in the East China region decreased and prices increased. However, the follow-up of spot transactions has been slow, and the northern maintenance facilities have gradually resumed, resulting in a halt in the rise and subsequent decline of spot prices in the middle of the month. However, spot buying remains in a state of rigid demand, resulting in limited demand growth and a temporary market downturn. However, considering cost pressures and future stocking expectations, the market’s downward space in the short term is still limited.
Recently, the domestic butadiene market has been fluctuating and consolidating after a decline. The current domestic production has slightly declined, coupled with limited port arrivals, which has slightly boosted the supply side. However, the downstream synthetic rubber market trend is weak, and buyers’ enthusiasm for entering the market is low, lacking demand support. It is expected that the butadiene market will be weak and volatile in the short term. From the expectation of pre holiday stocking demand, there is some upward potential in the butadiene market in the latter half of the year.
Styrene has recently maintained a range oscillation trend. In the first half of the year, domestic factories started operating at a high level, and the raw material pure benzene fell. From the perspective of market performance, the price center of gravity has basically exhausted after the middle of the month. Recently, pure benzene and rising crude oil and styrene port inventories have appeared simultaneously, causing a dilemma between long and short positions in the market. In the future, due to the weak impact of its own fundamentals, styrene may have limited upward space.
On the demand side: In the medium to long term, the downstream factories of ABS have had average loads. The current market still exhibits significant off-season characteristics, and terminal enterprises have not yet started stocking up before the holiday, with logic still maintaining a strong demand for supplementary orders. The consumption of the main downstream electrical appliance shell industry is quiet, and there is no increase in production scheduling. The cautious atmosphere in the external market remains unchanged, and the flow of goods is slow. Domestic inventory levels remain strong at high levels, supply continues to be loose, and there is increased pressure to sell on the market. Overall, there has been no improvement in the demand side’s support for the ABS market.
Future forecast
As the holiday approaches, the domestic ABS market remains weak. The upstream three materials may fall or consolidate, and the production load of ABS polymerization plant remains stable with small fluctuations, while consumer demand has not shown any increase. Analysts from Shengyi Society believe that the long-term drag on spot prices of ABS due to supply and demand contradictions makes it difficult for the market momentum to improve. The current ABS market atmosphere is light, with high resistance to upward movement. It is expected that ABS may continue to decline in the short term.

According to the monitoring of the commodity market analysis system of Shengyi Society, the average price of LLDPE (7042) was 7378 yuan/ton on September 15th and 7395 yuan/ton on September 18th, with a rate of 0.23% last week. LDPE (2426H) had an average price of 9593 yuan/ton on September 15th and 9600 yuan/ton on September 18th, an increase of 0.07%. HDPE (2426H) had an average price of 7957 yuan/ton on September 15th and 7957 yuan/ton on September 18th, with a stable quotation.
Polyethylene prices have been weak this week, with a narrow upward adjustment. The market supply side is relatively sufficient. On the demand side, the agricultural film industry is in the traditional peak season of demand, with greenhouse film production maintaining a high level. The orders for northern plastic film have increased, and factory production is gradually increasing; The construction of other industries is relatively stable, with cautious procurement and a focus on essential purchases. The demand side has limited support for polyethylene. On the cost side, on September 18th, international crude oil futures closed down due to weakened demand after the end of the traditional fuel consumption peak season in the United States, and the continued increase in OPEC+production, which weakened the cost side and suppressed the polyethylene spot market.
Polyethylene supply is sufficient, and there are positive expectations on the demand side; It is expected that polyethylene will mainly operate in a narrow range, and the upward space may be limited.
