The Singapore refining margin has decreased to $12.55 per barrel [53][55]. - The polyester sector is facing a decline in PTA profitability, while polyester filament profitability is on the rise. The report suggests that the overall performance of the polyester industry is average, with potential for improvement as new capacity slows down [53][60].

The report indicates a potential for oil prices to decline in the medium term, despite current upward trends [23][39]. - The report also notes a decrease in the number of active drilling rigs in the U.S., which may impact future production levels [33]. Refining Sector - The report highlights a decrease in refining margins and crack spreads, indicating challenges in profitability for refiners.

Polyester Sector - The report indicates a mixed performance in the polyester sector, with PTA profitability declining while polyester filament profitability is improving. It emphasizes the need to monitor demand changes closely [53][60].
