Industry Investment Rating - No relevant content provided Core Viewpoints - The sentiment in the commodity market has improved, the supply of domestic PTA production capacity has contracted, the port inventory of PTA has declined, and a large number of warehouse receipts are being cancelled. The spread between PX and naphtha has expanded to around $250, and the profitability of alkyl transfer and TDP is not optimistic. The spread between PX and MX remains at around $90. Bottle chips and staple fibers are about to enter the maintenance cycle in July. The market port inventory is being depleted, and polyester replenishment has improved with the weakening of the basis. The basis of PTA has rebounded from 0 to 30. The maintenance of Northeast PX plants and Zhejiang reforming units has been postponed. The early maintenance of mainstream PTA factories has significantly boosted the market [2]. - The coal price has rebounded, leading to an increase in the price of ethylene glycol (MEG). The macro - sentiment has clearly improved, and the chemical industry has followed the warming sentiment of commodities. The maintenance of overseas MEG plants, especially Saudi Arabian ones, has been continuously postponed, which may have a significant impact on the future market and has been boosting the price of MEG. The future arrival volume of MEG is expected to decrease. The polyester production and sales have weakened, and polyester has entered the maintenance cycle. Due to the rapid increase in polyester prices, the profit of downstream weaving has shrunk, and the terminal load has significantly declined, which has a certain negative impact on the market [2].
