Report Industry Investment Rating - Not provided in the content Core Viewpoints - Port remains weak with rapid inventory accumulation this week. Overseas methanol plants are operating at a high level, increasing the arrival pressure. The downstream MTO device, Xingxing, will be shut down for one - month maintenance starting at the end of July. There is a possibility of methanol production reduction in Shandong during the military parade. Inland methanol prices are stronger than those at the port. Inland factory inventory is low, and coal - based methanol production is on the rise, with further recovery expected at the end of August. Some downstream industries like acetic acid are seeing a decline in production, and formaldehyde is in a seasonal off - season [2] Summary by Directory I. Methanol Basis & Inter - period Structure - Figures show methanol basis in different regions (Taicang, Lunan, Inner Mongolia North Line, Henan, Hebei, Guangdong) against the main futures contract, and inter - period spreads between different methanol futures contracts (01 - 05, 05 - 09, 09 - 01) [5][6][10][11][14][22][24] II. Methanol Production Profit, MTO Profit, Import Profit - Figures display Inner Mongolia coal - based methanol production profit, East China MTO profit (PP&EG type), import spread between Taicang methanol and CFR China, and price differences between CFR Southeast Asia, FOB US Gulf, FOB Rotterdam and CFR China [5][26][30][34] III. Methanol Production and Inventory - Figures present total port inventory, MTO/P operating rate (including integrated plants), inland factory sample inventory, and China's methanol operating rate (including integrated plants) [5][36][38] IV. Regional Price Differences - Figures show price differences in different regions such as Lubei - Northwest - 280, East China - Inner Mongolia - 550, Taicang - Lunan - 250, Lunan - Taicang - 100, Guangdong - East China - 180, and East China - Sichuan - Chongqing - 200 [5][40][47][50] V. Traditional Downstream Profits - Figures illustrate the production margins of Shandong formaldehyde, Jiangsu acetic acid, Shandong MTBE isomerization etherification, and Henan dimethyl ether [5][51][58] Strategy - Unilateral: Wait and see - Inter - period: Do reverse arbitrage on MA09 - 01 inter - period spread when it is high - Cross - variety: Narrow the spread between PP2601 and 3MA2601 when it is high [3]
