1. Report Industry Investment Rating - Unilateral: Neutral. Maintain a neutral stance on domestic supplies, but keep an eye on cost changes due to low inventories and unexpected overseas operations [3] 2. Core Viewpoints - Yesterday, the closing price of the main EG contract was 4,367 yuan/ton (a decrease of 39 yuan/ton from the previous trading day), the spot price in the East China EG market was 4,488 yuan/ton (unchanged from the previous trading day, a change of +0.00%), and the spot basis in East China EG (based on the 2509 contract) was 82 yuan/ton (an increase of 6 yuan/ton month-on-month). The production profit of ethylene-based EG was -$48/ton (a decrease of $2/ton month-on-month), and the production profit of coal-based syngas EG was -59 yuan/ton (a decrease of 30 yuan/ton month-on-month). The inventory of the main ports in East China increased this week [1] - In terms of supply, the domestic load of ethylene glycol syngas production has returned to a high level and can be further increased under favorable conditions. Overseas, the restart of some units has not gone smoothly, and the increase in EG imports has been lower than expected. In terms of demand, the inventory pressure of filament has been greatly alleviated, and the polyester load is expected to remain stable in the short term. The balance sheet shows a slight inventory build-up in August, with a lack of sustainability in the increase of port inventories, and the supply-demand contradiction is not significant [2] 3. Summary by Directory Price and Basis - Yesterday, the closing price of the main EG contract was 4,367 yuan/ton (a decrease of 39 yuan/ton from the previous trading day), the spot price in the East China EG market was 4,488 yuan/ton (unchanged from the previous trading day, a change of +0.00%), and the spot basis in East China EG (based on the 2509 contract) was 82 yuan/ton (an increase of 6 yuan/ton month-on-month) [1] Production Profit and Operating Rate - The production profit of ethylene-based EG was -$48/ton (a decrease of $2/ton month-on-month), and the production profit of coal-based syngas EG was -59 yuan/ton (a decrease of 30 yuan/ton month-on-month) [1] International Price Difference - No specific data or analysis provided in the given text Downstream Production, Sales, and Operating Rate - In July, there was a concentrated restocking at the terminal, and the inventory pressure of filament was greatly alleviated.

Report Industry Investment Rating No relevant information provided. Core Views of the Report - In July, the ethylene glycol (EG) price rose and then slightly declined, with the spot basis oscillating downward. The price was influenced by factors such as anti - involution policy expectations, coal price fluctuations, port inventory, and typhoon - affected shipping schedules [2][10]. - Domestic supply of EG is expected to increase. In 2025, 160 million tons of new MEG devices are expected to be put into production, and the EG load steadily recovered in July, with the syngas - based load likely to further increase in August [3][13]. - Overseas supply shows different trends in various regions. The total EG imports from July to September are estimated to be 67, 60, and 65 million tons respectively, mainly due to the growth of supplies from Saudi Arabia and Malaysia [4][37][38]. - In July, the weaving and texturing load first dropped rapidly and then rebounded slightly. The polyester load decreased slightly at the beginning of the month but remained relatively stable. The demand side is expected to improve with the arrival of the seasonal peak season in late August [5][69]. - In July, the EG balance sheet is expected to have a slight inventory build - up of about 4 million tons, and in August, it is expected to have a slight build - up of about 8 million tons, with the East China port inventory expected to remain low and slightly increase [6][55]. - The trading strategy suggests a cautious and bearish stance on the unilateral position due to weakening market sentiment and coal price decline. There are no suggestions for cross - variety and cross - period strategies [7]. Summary by Relevant Catalogs EG Price and Basis Structure Review - In July, the EG price rose and then slightly declined, and the spot basis oscillated downward. The price was affected by macro - sentiment improvement, coal price rebound, and later by factors such as coal position limits, port low inventory, and oil price rebound [2][10]. EG Domestic Fundamental - **EG Subsequent Domestic New - added Capacity**: In 2025, 160 million tons of new MEG devices are expected to be put into production. The 60 - million - ton Sichuan Zhengdakai device was put into production in May, and the remaining two sets are expected to be put into production in Q4 [3][13]. - **EG Operating Rate and Monthly Maintenance Forecast**: The EG load steadily recovered in July at a rate lower than expected. The syngas - based load has returned to a relatively high level, and it is expected to further increase in August under high - profit conditions, leading to an increase in domestic EG supply [3][15]. - **China EG Weekly Maintenance Forecast**: No specific content in the provided text, only the title is given. EG Outer - Market Situation - **Overseas EG Monthly Maintenance Forecast**: In North America, most devices restarted in July, but US imports decreased due to tariffs. Canadian devices operate normally, and the Shell 50 - million - ton/year device plans a 45 - day maintenance in September. In the Middle East, Saudi devices restarted in June but had power - related shutdowns in July. Iranian imports are expected to be 9 million tons in July, 6 million tons in August, and rebound in September. In Asia, Malaysian devices restarted, and Taiwan devices operate at full - load. South Korean imports are relatively low [37][38]. - **Overseas EG Weekly Maintenance Forecast**: No specific content in the provided text, only the title is given. - **EG International Price Difference**: No specific analysis content in the provided text, only the title and some related chart information are given. EG Inventory Trend - In July, the EG balance sheet is expected to have a slight inventory build - up of about 4 million tons, with a slight decrease in port visible inventory and an increase in invisible inventory. In August, with increased domestic supply and decreased imports, a slight build - up of about 8 million tons is expected, and the East China port inventory is expected to remain low and slightly increase [6][55]. Downstream Weaving and Polyester Situation - In July, the weaving and texturing load first dropped rapidly and then rebounded slightly. The polyester load decreased slightly at the beginning of the month but remained relatively stable. Currently, orders have not improved significantly, and the reduction in filament inventory is mainly due to downstream transfer. However, the short - term reduction pressure on polyester load has decreased, and the demand side is expected to improve with the arrival of the seasonal peak season in late August [5][69].

Report Industry Investment Rating - Unilateral: Neutral - Inter-period: None - Inter-variety: None [3] Core Viewpoints - Market analysis shows that in the futures and spot markets, the closing price of the main EG contract was 4,450 yuan/ton (a change of -17 yuan/ton or -0.38% from the previous trading day), the spot price of EG in the East China market was 4,525 yuan/ton (a change of +7 yuan/ton or +0.15% from the previous trading day), and the spot basis of EG in East China (based on the 2509 contract) was 66 yuan/ton (a month-on-month increase of 4 yuan/ton). With market news calming down, EG fluctuated widely, and the basis rose under the influence of typhoons. In terms of production profit, the production profit of ethylene-based EG was -$39/ton (a month-on-month increase of $4/ton), and that of coal-based syngas EG was 98 yuan/ton (a month-on-month increase of 13 yuan/ton). Regarding inventory, according to CCF data released every Monday, the inventory of MEG at the main ports in East China was 521,000 tons (a month-on-month decrease of 12,000 tons); according to Longzhong data released every Thursday, it was 475,000 tons (a month-on-month decrease of 19,000 tons). The actual arrival at the main ports last week was 108,000 tons, lower than the planned value, and the port inventory decreased slightly. This week, the planned arrival at the main ports in East China is 156,000 tons, with concentrated arrivals, so actual arrivals should be monitored [1]. - In terms of the overall fundamental supply-demand logic, on the supply side, domestically, the load of ethylene glycol syngas production has returned to a high level and can be further increased under favorable conditions. Some EO-EG co-production plants in non-coal sectors have plans or actions to switch from EO to EG, and the overall load is moderately high. Overseas, the Sharq series of plants in Saudi Arabia have restarted, and in an ideal situation, the supply of ocean freight will gradually return to normal, with an expected increase in imports. On the demand side, due to the price increase effect, the terminal has replenished inventory intensively, greatly alleviating the inventory pressure of filaments. It is expected that the polyester load will remain strong in the short term, and attention should be paid to the order connection in August. Overall, there will be concentrated arrivals of foreign vessels in late July, and there is pressure for the fundamentals to weaken in August under high supply [2].

The planned arrival at the East China main port this week is 15.7 tons, and the visible inventory is expected to rise moderately early next week [2]. - For the overall fundamental supply - demand logic, on the supply side, the domestic synthetic gas - made glycol load has returned to a high level, with more unplanned load reductions in non - coal production, and limited room for further improvement. Overseas supply recovery was less than expected due to the poor restart of Saudi Arabian plants. On the demand side, terminal inventory was high and the willingness to stock up was low during the off - season, with weak demand expectations. However, the actual decline in demand may be limited, and the supply - demand structure in July was still favorable, but the pressure of foreign vessel arrivals would increase moderately in late July [2]. - In terms of strategy, the short - term performance is strong under the concentrated release of macro - policies, and the medium - term view is neutral. Attention should be paid to macro - sentiment [3]. 3.
