The cost of methanol to aviation kerosene is about 2270 yuan/ton, and the disk price is also 2800 yuan/ton. The upstream of methanol is about to undergo spring inspection, and the supply is expected to shrink. Imported goods and mainland goods arrive in Hong Kong steadily, and the port inventory pressure accumulates. Downstream recovery production is slow, and olefin recovery space is limited. On the whole, the supply and demand of the 2205 contract is weak, the price remains volatile, and the space below 2800 yuan/ton is limited.
