Report Industry Investment Rating - Unilateral: Neutral [3] - Inter - period: Do reverse spreads on the MA09 - 01 inter - period spread when it is high [3] - Inter - variety: Narrow the PP01 - 3MA01 spread when it is high [3] Core View - Overseas methanol production remains at a high level, resulting in significant pressure on Chinese imports and a continuous inventory build - up at ports. The short - term reality at ports is weak, but the market anticipates a substantial scale of overseas gas - based methanol maintenance in the fourth quarter, leading to an optimistic long - term outlook. Inland coal - based methanol is undergoing short - term maintenance, reducing supply. Although the traditional downstream formaldehyde market is in a seasonal off - season, the开工 rates of MTBE and acetic acid are decent, indicating strong inland demand. As a result, the inventory build - up rate at inland methanol factories is slow, and the inland market is stronger than the port market [2] Summary by Directory 1. Methanol Basis & Inter - period Structure - The report presents multiple figures related to methanol basis, including methanol basis in Taicang, different regions' spot - to - futures basis, and inter - period spreads between different methanol futures contracts [6][10][21] 2. Methanol Production Profit, MTO Profit, and Import Profit - Figures show the production profit of inland coal - based methanol, MTO profit in East China, and import spreads such as the difference between Taicang methanol and CFR China, as well as price differences between CFR Southeast Asia, FOB US Gulf, FOB Rotterdam, and CFR China [25][33] 3. Methanol Production and Inventory - Information on methanol port total inventory, MTO/P production rate (including integrated plants), inland factory sample inventory, and China's overall methanol production rate (including integrated plants) is provided [35][37] 4. Regional Price Differences - The report provides data on regional price differences, such as the price difference between northern Shandong and the northwest, East China and Inner Mongolia, Taicang and southern Shandong, and other regions [39][45][48] 5. Traditional Downstream Profits - Figures display the production margins of traditional downstream products, including formaldehyde in Shandong, acetic acid in Jiangsu, MTBE isomerization etherification in Shandong, and dimethyl ether in Henan [55][57]
