1. Report Industry Investment Rating No information provided. 2. Core View of the Report - The Middle - East situation is tense, and the methanol basis is firm. The price increase of aromatics is due to supply - side issues in the Middle - East, leading to a decline in Asian refinery and cracking operations. In ports, the basis remains high and firm, and the de - stocking in ports is related to the duration of Iranian methanol plant shutdowns. Coal - based methanol production has high profits, and the spring inspection scale is limited. Inland factory inventories continue to decline, and traditional downstream operations are good [1][3]. 3. Summary According to the Catalog I. Methanol Basis & Inter - period Structure - Multiple figures show the basis between methanol spot in different regions (such as Taicang, Lunan, Inner Mongolia North Line, etc.) and the main futures contract, as well as the price differences between different methanol futures contracts (e.g., methanol 01 - 05, 05 - 09, 09 - 01) [6][7][19] II. Methanol Production Profit, MTO Profit, and Import Profit - Figures display the production profit of Inner Mongolia coal - based methanol, the MTO profit in East China (PP&EG type), and the import price differences such as Taicang methanol - CFR China, CFR Southeast Asia - CFR China, FOB US Gulf - CFR China, and FOB Rotterdam - CFR China [6][23][25] III. Methanol Start - up and Inventory - Figures present the total port inventory of methanol, the MTO/P start - up rate (including integrated ones), the inland factory sample inventory, and the start - up rate of Chinese methanol (including integrated ones) [6][30][37] IV. Regional Price Differences - Figures show price differences between regions, such as the price difference between North Shandong and Northwest, East China and Inner Mongolia, Taicang and Lunan, etc. [6][34][41] V.

Report Summary 1. Investment Rating - **Unilateral**: Neutral - **Inter - period**: None - **Inter - commodity**: None [4] 2. Core View - The situation between the US and Iran remains a focus, but the lack of further escalation has dragged down the market sentiment. Attention should be paid to its subsequent development. - In the port area, the loading volume from Iran in February continued to decline, leading to expectations of a destocking cycle in March. However, port inventories still slightly accumulated after the Spring Festival, and the inventory pressure persists. The winter - shutdown devices in Iran are recovering, and the resumption rhythm of the remaining devices in early March should be monitored. Some downstream MTO devices are under maintenance, and their resumption progress should be followed. - In the inland area, inland factory inventories have rapidly increased seasonally after the Spring Festival. Coal - based methanol maintains high - level operation, while the traditional downstream is in a seasonal off - peak period, waiting for the post - festival load increase of formaldehyde [3]. 3. Summary by Directory 3.1 Market News and Key Data - **Inland Area**: Q5500 Ordos thermal coal is priced at 515 yuan/ton (unchanged), and the production profit of coal - based methanol in Inner Mongolia is 325 yuan/ton (down 38 yuan). Inner Mongolia's northern line methanol is 1830 yuan/ton (down 38 yuan), with a basis of 220 yuan/ton (up 2 yuan); the southern line is 1850 yuan/ton (down 10 yuan). Shandong Linyi is at 2175 yuan/ton (down 18 yuan), with a basis of 165 yuan/ton (up 22 yuan); Henan is 2030 yuan/ton (down 20 yuan), with a basis of 20 yuan/ton (up 19 yuan); Hebei is 2075 yuan/ton (up 20 yuan), with a basis of 125 yuan/ton (up 59 yuan). Longzhong's inland factory inventory is 535,410 tons (up 195,030 tons), northwest factory inventory is 346,600 tons (up 177,500 tons); inland factory pending orders are 206,751 tons (down 108,280 tons), and northwest factory pending orders are 82,500 tons (down 77,500 tons) [1]. - **Port Area**: Taicang methanol is priced at 2197 yuan/ton (down 35 yuan), with a basis of - 13 yuan/ton (up 4 yuan), CFR China is 267 US dollars/ton (down 2 US dollars), and the East China import spread is - 24 yuan/ton (up 13 yuan). Changzhou methanol is 2255 yuan/ton; Guangdong methanol is 2202 yuan/ton (down 33 yuan), with a basis of - 8 yuan/ton (up 6 yuan). Longzhong's total port inventory is 1,446,697 tons (up 14,514 tons), Jiangsu port inventory is 722,915 tons (up 36,232 tons), Zhejiang port inventory is 321,282 tons (down 36,718 tons), and Guangdong port inventory is 225,000 tons (up 23,000 tons).

1. Report Industry Investment Rating - Unilateral: Neutral [4] 2. Core Viewpoints - The real inventory pressure in the port area remains high, and the window for the port to flow back to the mainland is closed, dragging down port pick - up. Although the Iranian methanol plant is operating at a low level, the actual decline in shipping volume due to plant maintenance needs further confirmation, and the decline rate of shipping volume in December is still slow. There are concerns about the possible maintenance of Xingxing's MTO plant [2]. - Downstream demand in the mainland is in the seasonal off - season, and factory inventories are gradually rebuilding. Coal - based production maintains high operation rates, and attention should be paid to the resumption progress of southwest gas - based plants in the middle and late ten - days. The seasonal low of pending orders in the northwest drags down the pick - up demand for port - to - mainland back - flow. Among traditional downstream industries, the acetic acid operation rate has rebounded from the bottom, the MTBE operation rate is still acceptable, and the formaldehyde operation rate has declined slightly [3]. 3. Summary by Directory 3.1 Methanol Basis & Inter - Period Structure - The report presents charts of methanol basis in different regions (such as Taicang, Lunan, Inner Mongolia North Line, etc.) relative to the main futures contract, and the price differences between different methanol futures contracts (e.g., methanol 01 - 05, 05 - 09, 09 - 01) [7][9][21] 3.2 Methanol Production Profit, MTO Profit, and Import Profit - The report shows charts of Inner Mongolia coal - based methanol production profit, East China MTO profit (PP&EG type), Taicang methanol - CFR China import price difference, and price differences between CFR Southeast Asia, FOB US Gulf, FOB Rotterdam and CFR China [25][26][33] 3.3 Methanol Operation Rate and Inventory - The report provides charts of methanol port total inventory, MTO/P operation rate (including integrated plants), mainland factory sample inventory, and China's methanol operation rate (including integrated plants) [34][43] 3.4 Regional Price Differences - The report includes charts of price differences in different regions, such as Lubei - Northwest - 280, East China - Inner Mongolia - 550, Taicang - Lunan - 250, etc. [40][48][52] 3.5 Traditional Downstream Profits - The report shows charts of production profits of traditional downstream products such as Shandong formaldehyde, Jiangsu acetic acid, Shandong MTBE isomerization etherification, and Henan dimethyl ether [50][58] 3.6 Strategies - Inter - period: Expand the spread of MA2605 - MA2609 when it is low [4] - Cross - variety: Narrow the spread of LL2605 - 3*MA2605 when it is high [4]

Report Industry Investment Rating - Not provided in the given content Core Viewpoints - The port inventory accumulation pace has slowed down for the first time. After the restart of the downstream MTO Xingxing, it supported the port demand, and the port inventory remained basically flat this week. However, the subsequent arrival pressure is still high, and the subsequent changes mainly depend on when the Iranian winter inspection plan will be announced [3] - The lowest point of coal - based methanol production has passed, but it will not return to a high level until the second half of the month. The inventory of inland methanol plants is still low, and overall, the inland market is stronger than the port market. The window for port re - flow to the inland is an important variable supporting the lower limit of port prices. The high - start acetic acid production has peaked and declined, and formaldehyde is in a seasonal off - season, waiting for a further bottom - up recovery. Attention should be paid to the decline in the resilience of inland demand [3] Summary by Directory 1. Methanol Basis & Inter - period Structure - Includes figures such as methanol Taicang basis and the main methanol contract, methanol basis in different regions relative to the main futures contract, and the price differences between different methanol futures contracts (e.g., methanol 01 - methanol 05, methanol 05 - methanol 09, methanol 09 - methanol 01) [7][22] 2. Methanol Production Profit, MTO Profit, and Import Profit - Involves figures related to Inner Mongolia coal - based methanol production profit, East China MTO profit (PP&EG type), and import price differences such as Taicang methanol - CFR China, CFR Southeast Asia - CFR China, FOB US Gulf - CFR China, FOB Rotterdam - CFR China [26][30] 3.

Report Summary 1. Report Industry Investment Rating No investment rating for the industry is provided in the report. 2. Core View The expectation of capacity reduction in South Korea's naphtha cracking has led to a rebound in the prices of olefin derivatives, which in turn has driven up the methanol price. However, the current situation at the port remains weak, with port inventories continuing to rise and downstream MTO in the maintenance cycle. The centralized maintenance period for coal - based methanol is gradually over, and the operating rate will increase in late August. This week, the inventory of inland factories has bottomed out and rebounded, while downstream orders have declined. For the downstream, formaldehyde is in a seasonal off - season and is waiting for a further bottom - up recovery [3]. 3. Summary by Directory I. Market News and Important Data - **Inland**: Q5500 Ordos thermal coal is 470 yuan/ton (unchanged), and the production profit of coal - to - methanol in Inner Mongolia is 655 yuan/ton (unchanged). Inland methanol prices vary by region, with Inner Mongolia North Line at 2070 yuan/ton (unchanged), Inner Mongolia South Line at 2080 yuan/ton (unchanged), Shandong Linyi at 2345 yuan/ton (+11), etc. The inventory of inland factories has increased to 310,793 tons (+15,220), and the order backlog has decreased to 207,370 tons (-11,995) [1]. - **Port**: Taicang methanol is 2305 yuan/ton (+25), CFR China is 259 US dollars/ton (-2). The total port inventory has increased to 1,075,960 tons (+54,160), and the downstream MTO operating rate is 83.12% (-0.77%). There are also various regional price differences [2]. II. Market Analysis The expectation of capacity reduction in South Korea's naphtha cracking has driven up the prices of olefin derivatives and methanol. But the port situation is weak, with rising inventories and MTO in maintenance. The coal - based methanol maintenance period is over, and the operating rate will increase. Inland factory inventories have rebounded, and downstream orders have decreased. Formaldehyde is in a seasonal off - season [3]. III. Strategy For single - side trading, inter - period trading, and cross - variety trading, the recommendation is to wait and see [4]. IV. Figures and Tables by Category - **Methanol Basis & Inter - period Structure**: There are figures showing methanol basis in different regions (such as Taicang, Lunan, Inner Mongolia North Line, etc.) and inter - period spreads between different futures contracts (e.g., methanol 01 - 05, 05 - 09, 09 - 01) [6][7][22]. - **Methanol Production Profit, MTO Profit, Import Profit**: Figures display the production profit of coal - based methanol in Inner Mongolia, MTO profit in East China, and import profit (e.g., Taicang methanol - CFR China import spread) [6][26][30]. - **Methanol Operating Rate, Inventory**: Figures show methanol port total inventory, MTO/P operating rate, inland factory sample inventory, and China's methanol operating rate [6][32][33]. - **Regional Price Differences**: Figures present price differences between different regions, such as Lubei - Northwest, East China - Inner Mongolia, etc. [6][37][45]. - **Traditional Downstream Profits**: Figures show the production profits of traditional downstream products like Shandong formaldehyde, Jiangsu acetic acid, Shandong MTBE, and Henan dimethyl ether [6][50][55].
