1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The post - holiday port inventory of methanol has slightly increased, with expectations for the port to enter a destocking cycle in March as China's arrivals continue to decline and Iran's February shipment volume drops more than expected. The restart of Iran's winter - shutdown plants is slow. Downstream MTO plants such as Xingxing and Shenghong are under maintenance, and their restart progress needs attention [2][3]. - After the holiday, the inventory of inland factories has rapidly increased seasonally. Coal - based methanol maintains high - level operation, and the traditional downstream is in the seasonal off - season, waiting for formaldehyde to increase production after the holiday [3]. 3. Summary by Relevant Catalogs I. Methanol Basis & Inter - period Structure - The report includes multiple figures related to methanol basis and inter - period spreads, such as methanol Taicang basis and main contract, methanol basis in different regions against the main futures, and spreads between different methanol futures contracts [6][7][13] II.
