PX is in a high - level volatile market, PTA has strong cost support, and MEG is expected to rebound due to the anticipated supply contraction under new energy consumption standards [1][2] - The outlook for PX in 2026 remains optimistic, and the narrowing spread between February and March may indicate healthy demand. However, the future PTA exports to India may decrease significantly.

It is recommended to operate in the range of 6550 - 7000, close the 5 - 9 bull spread, and take profit on the long PX and short PTA/BZ positions [8] - PTA: The supply and demand of PX at the cost end are tight, but the polyester is starting to accumulate inventory and incur losses. There may be a negative feedback in the industrial chain due to potential production cuts. Therefore, the upside space of PTA is limited. It is recommended to operate in the range of 4500 - 4800, close the 5 - 9 bull spread, and take profit on the long PX and short PTA/BZ positions [9] - MEG: The market is concerned about the impact of new energy consumption standards on coal - based plants. The current price of 3600 yuan/ton has reached the cost line of most production plants, leading to some plants' operational shutdowns. The supply - demand pattern has slightly improved. Do not chase short positions in the 01 contract. Low profits have led to a widespread decline in plant operating enthusiasm. It is necessary to pay attention to the restart of the 200,000 - ton Huayi plant [9]
