On September 21st, the domestic epoxy propane market experienced a weak downward trend. The mainstream negotiated price in Shandong has dropped to 11070-11100 yuan/ton, a decrease of 500 yuan/ton from the previous trading day; The Northeast region has synchronously decreased by 400 yuan/ton. As of September 21st, the benchmark price of epoxy propane in Shengyi Society was 11233.33 yuan/ton, an increase of 17.01% compared to the beginning of this month.
On the raw material side, cost support has weakened. Previously, the price of propylene was strongly supported by the rising costs of crude oil and propane, but after entering this week, there were signs of a decline in crude oil and propylene prices, and the cost side’s support for epoxy propane weakened, leading to a bearish market sentiment. As of September 21st, the benchmark price of propylene in Shengyi Society was 9641.00 yuan/ton, an increase of 7.39% compared to the beginning of this month (8977.67 yuan/ton).
Supply side: Early maintenance devices are gradually being restarted. The device has resumed operation, and the market supply has significantly increased compared to the previous period, easing the tight spot situation. The domestic capacity utilization rate has rebounded from around 64% to around 70%, and the expected increase in supply is gradually being implemented.
On the demand side, the peak season of “Golden September” has shown mild performance, and the overall operating rate of downstream polyether enterprises is not high. There is a clear resistance to high priced raw materials, and they mainly purchase small orders for essential needs, with limited increase in new orders. Other downstream products such as propylene glycol also show a stalemate pattern of cost support and weak demand, with insufficient follow-up on epoxy propane procurement.
Comprehensive forecast: Loose cost support combined with increased supply realization, coupled with weak downstream demand follow-up, may lead to a weak consolidation trend in the short-term epoxy propane market. It is necessary to focus on the pace of device restart and volume increase, as well as changes in downstream stocking willingness.

Since September, the domestic natural rubber market has experienced a period of initial rise and subsequent decline, with fluctuations within a range. As of September 20th, the market price of natural rubber in China was around 18150 yuan/ton, an increase of 0.14% from 18125 yuan/ton at the beginning of the month, with a peak of 18866 yuan/ton during the cycle. During the cycle, the main contract of Shanghai rubber hit a high of 19810 yuan/ton, reaching a new high in nearly two years. After surging, it fell back to around 18670 yuan/ton, and the long short game was intense. ​
Strong supply side support:
ANRPC predicts a global production of 15.32 million tons and consumption of 15.6 million tons of natural rubber in 2026, with a supply-demand gap of 280000 tons for the whole year.
Currently, Southeast Asia is entering a peak production season, but continuous rainfall is disrupting rubber harvesting, coupled with aging rubber trees in Thailand and rubber diseases in Indonesia, resulting in less than expected release of raw materials.
The port inventory maintains a destocking trend. As of September 13th, the total inventory of Qingdao Free Trade Zone and general trade was 603200 tons, a decrease of 15800 tons compared to the previous month, and continued to slowly reduce inventory. Domestic spot inventory is low. At the same time, the price of butadiene has risen, the cost of synthetic rubber has increased, and downstream substitution procurement has increased, further supporting the bottom rubber price.
The demand side suppresses the upward trend of prices. On September 11th, the domestic semi steel tire production rate was 65.53%, a year-on-year decrease of 7.93%; The operating rate of all steel tires was 63.53%, a year-on-year decrease of 2.06%. The inventory turnover of semi-finished steel tires is 44.7 days, while that of all steel tires is 36.4 days. The demand for end commercial and passenger vehicles is relatively weak. Although tire companies have issued price increase letters, with a 2% -5% increase, the high prices of raw materials have suppressed profits, and factories only maintain essential purchases. There is insufficient willingness to proactively replenish inventory, and the peak season delivery falls short of expectations. ​
Market forecast:
From a technical perspective, the current spot price of natural rubber has fallen below the 5-day moving average, indicating a decline in short-term bullish momentum; The 10/20 day moving average is still upward, and the medium-term trend remains strong. In the short term, it belongs to the high-level retracement stage, supported by the 20 day moving average. If the moving average is held, the market is likely to fluctuate at a high level; If it effectively falls below, further pullback will release pressure. The overall short-term trend is weakening, and the medium-term upward structure has not been completely destroyed. ​
Fundamentally speaking, natural rubber is expected to maintain a high range of volatility in the short term. The strong production season on the supply side is coming to an end, and the expectation of reduced production is increasing. Thai cup glue provides cost support at 74.2 baht/kg. The demand side is unlikely to show significant improvement in the short term, and the increase in tire maintenance is suppressing procurement. Combined with macroeconomic and geopolitical factors, it can be concluded that there is significant pressure above the rubber price and cost support below, making it difficult to see a significant unilateral market trend in the short term.

1、 Trend analysis
This week, nickel prices have shown a “V” shaped trend. As of the weekend, the spot nickel price was 125866.67 yuan/ton, a decrease of 0.32% from the beginning of the week and a year-on-year increase of 2.32%.
Macroscopically, this week the Federal Reserve raised interest rates by 25bp as scheduled to 3.75% -4.00%, with a bearish candlestick chart and the US dollar index returning to above 100%. However, the sentiment of “all bearish sentiment” dominated, and basic metals generally rose. The marginal suppression of nickel prices on a macro level has weakened.
In terms of raw materials, the new HPM policy in Indonesia has been implemented, and the correction factor for low-grade wet ore has been reduced by about 45%. The new HPM for 1.2% nickel ore has dropped to $24.89 per wet ton, which is lower than the actual factory price, and the cost support for the mining end has been lowered. The supply of nickel ore in the Philippines has reached its peak, and port inventories have rebounded. The transaction price of nickel iron has fallen to 1070-1085 yuan/nickel, and the overall operation of the raw material side is weak.
On the supply side: Indonesia’s WBN has received new quotas from RKAB, strengthening expectations of loose supply, but ESDM denies approval news, and policy uncertainty still exists. El Ni ñ o drought poses a 30% -40% reduction risk for the wet process project in IMIP park, and a certain HPAL project plans to reduce production by about 30% in September. Domestic refined nickel losses and production cuts are accelerating, and the supply side is intertwined with long and short positions.
In terms of demand, the quality of the “Golden September” peak season is insufficient, and the inventory of stainless steel 300 series has risen to 590900 tons. Steel mills mainly purchase for essential needs, and no large-scale replenishment has been seen. Top battery cell manufacturers in the new energy sector have lowered orders, while lithium iron phosphate continues to occupy the market share of ternary batteries. Nickel sulfate procurement is mainly based on long-term agreements, with few individual orders, and both demand engines are weak at the same time.
Influencing factors: The core variables are the pace of RKAB quota approval in Indonesia and the actual implementation of HPM new policies, with the policy aspect becoming the main driver of short-term nickel prices. At the same time, attention should be paid to the linkage impact of the Fed’s subsequent interest rate hike path on the US dollar and non-ferrous sectors, as well as whether the demand for stainless steel during the peak season can show marginal improvement in late September.
In summary, the macro bearish phase provides a rebound window, but the expectation of loose supply and high inventory (LME 279000 tons) suppress the upper space, and there is support from smelting costs below. It is expected that nickel prices will maintain a range bound fluctuation trend in the short term.

1、 Market Review
In the past week (September 9-15), the PA66 spot market has been consolidating strongly, with high prices remaining stagnant and the benchmark price maintaining at 19100.00 yuan/ton. Price fluctuations were limited during the week, and actual orders were mostly negotiated and sold. From the perspective of cycle position indicators, the 60 day cycle is in the high range, and the one-year price position is in the mid low range; The differentiation of the moving average signal, with a 5-day moving average remaining flat, a 10 day moving average falling, and a 20 day moving average rising, belongs to a strong consolidation (bullish) state under a volatile market, and has not yet formed a completely consistent unilateral trend signal.
2、 Cost analysis
The price of upstream adiponitrile has increased, and upstream chemicals such as acrylonitrile have strengthened, driving the increase in cost support for PA66 production. In the early stage, the slicing price was close to the industry cost line, and the pressure of enterprise losses was significant. The willingness to ship at low prices weakened, and leading enterprises had a strong mentality of raising prices; However, the overall supply of adiponitrile is relatively abundant, and there is currently no significant contraction in supply. The foundation for sustained surge in raw material prices is not yet available.
3、 Supply and demand analysis
On the supply side, the domestic PA66 plant has maintained a relatively high level of operation, with sufficient overall supply of goods and no obvious shortage of goods; After the price rebound, manufacturers’ enthusiasm for price increases, but there has been no large-scale production reduction or price protection operation, and the market circulation of goods is still acceptable. In terms of demand, driven by the expected peak season of “Golden September”, inquiries from downstream modification, injection molding, and textile airbag silk industries have rebounded, and there are some preventive replenishment behaviors; However, there has been no explosive growth in actual orders at the terminal, and downstream acceptance of high-level raw materials is limited. Most of them maintain on-demand procurement, and the willingness to stockpile in large quantities is not strong. The demand side is restraining the upward trend of prices. Under the game of supply and demand, the market maintains a pattern of high volatility and consolidation.
4、 Short term forecast
In the short term, the PA66 spot market is likely to continue its strong and volatile pattern. Cost support and peak season expectations are favorable for the market, and there is still some upward momentum; However, in the short term, the price is at a high level in the 60 day cycle, and downstream follow-up efforts are limited. There is significant resistance to sustained and significant surges, and it is expected to fluctuate within the range of 18700-19600 yuan/ton in the short term. The focus is on tracking the trend of adiponitrile raw materials and the actual landing of downstream autumn and winter orders.

In the first half of September, the dichloromethane market continued its strong upward trend since the end of August. As of September 15th, the mixed price of dichloromethane in Shandong region was 2395 yuan/ton, an increase of 11.66% from the beginning of the month.
Analysis of Market Driving Factors
Cost side: Strong upward trend of dual raw materials, forming the core driving force
The direct raw materials of dichloromethane are methanol and liquid chlorine, and their prices strengthened synchronously in the first half of September, which is the core driving force behind this round of rebound. Methanol continues to rise, with an increase of over 15% within half a month. The significant increase in methanol prices has directly pushed up the production cost of dichloromethane. Liquid chlorine has gradually rebounded from around 150 yuan/ton in early September, with an increase of over 100% within half a month. The rapid recovery of liquid chlorine has a significant marginal impact on the cost side.
Supply and demand: The supply is still relatively loose, and the demand is lukewarm
On the supply side, the operating rate of the methane chloride industry showed a rebound trend in the first half of September. In August, some major enterprises reduced their losses or stopped for maintenance, but there was a lack of obvious new maintenance plans in September. In addition, Gansu Juhua’s new production capacity is expected to be released, and the overall supply in the industry is still relatively loose.
On the demand side, September entered the traditional seasonal demand peak season, but the actual performance was mediocre. There is an expected growth in demand for R32 refrigerant in the core downstream sector, but the increase is limited due to flat terminal consumption; The overall orders for downstream solvents (coatings, pharmaceuticals, pesticides, etc.) are weak, and there is a lack of initiative to replenish inventory; The demand in the export market has also been lackluster. After a round of concentrated replenishment in early September, the enthusiasm of downstream and traders to receive goods began to decline in mid September, and the demand side’s ability to accept high prices has weakened.
Future forecast
Against the backdrop of high prices of raw materials such as methanol and liquid chlorine in the short term, the cost side still provides strong support for the bottom of prices, and manufacturers’ willingness to raise prices will not diminish in the short term. But after a rapid rise in early September, the price has risen to a temporary high, and downstream resistance to high prices has increased. The follow-up efforts of the demand side have slowed down, and the space for further significant upward movement is constrained. It is expected that the short-term market will mainly fluctuate at a high level and narrow range, digesting the previous gains.
