Report Industry Investment Rating - Unilateral: Neutral [4] Core Viewpoints - The overall inventory pressure at ports has eased, but the floating storage pressure caused by delayed unloading remains significant. The restart of an Iranian plant has led to fluctuations, and attention should be paid to the duration of winter maintenance of Iranian plants. Although the Iranian operating rate is low, the actual decline in shipping volume due to plant maintenance needs further confirmation. The MTO maintenance at Ningbo Fude has dragged down port demand [2] - The coal - based methanol production in the inland region is operating well, and there is seasonal winter maintenance of gas - based methanol in the southwest. The new MTO plant, Lianhong Phase II, is operating stably. Among traditional downstream industries, the acetic acid operating rate has slightly rebounded but remains low, the MTBE operating rate remains high, and the formaldehyde operating rate has slightly declined [3] Summary by Directory I. Methanol Basis & Inter - period Structure - The report presents multiple figures related to methanol basis and inter - period spreads, including methanol basis in different regions (such as Taicang, Lunan, Inner Mongolia North Line, etc.) against the main futures contract, and spreads between different methanol futures contracts (such as 01 - 05, 05 - 09, 09 - 01) [6][7][13] II.
