Report Overview - The report provides insights into the PX, PTA, and MEG markets, including price movements, market dynamics, and future trends [1][2][3] 1. Report Industry Investment Rating - Not provided in the given content 2. Core Views of the Report - PX: Supply is tight due to increased overseas aromatics blending demand and planned production cuts at the South Korean GS disproportionation unit, leading to rising prices. It's recommended to go long on PX and short on PTA/PF/PR, and conduct a long PX and short pure benzene hedging operation. The price will be in a high - level oscillating market [7] - PTA: The upside space may be limited, and it's advised not to chase high prices. With cost support, the monthly spread view is revised to mainly positive arbitrage. The pressure of inventory accumulation has eased [7] - MEG: The medium - term trend is weak. It's advisable to short at high prices, and maintain reverse arbitrage for monthly spreads. There is an oversupply situation, and the unilateral upward driving force is insufficient [8] 3. Summary by Relevant Catalogs Market Dynamics - PX: Naphtha prices were stagnant at the end of the session. PX prices rose, with two January Asian spot transactions at $832 and $831. The 1 - 2 month spread shifted from flat to continuous. Asian PX prices rebounded on November 19, mainly affected by the strong energy complex [3][4] - PTA: A 2.2 - million - ton PTA plant in East China started maintenance this week, expected to last 5 weeks [6] - Polyester: A new 100 - ton/day cationic staple fiber production line in a direct - spinning polyester staple fiber factory in northern Jiangsu was newly put into operation. A 300,000 - ton new polyester plant in Anhui and a 300,000 - ton new polyester filament plant in Xinjiang have started operation [6] Price and Spread Data - Futures: PX, PTA, PF, and SC futures prices rose, while MEG futures price fell. The monthly spreads of PX, PTA, MEG, PF, and SC all decreased [2] - Spot: PX, PTA, and naphtha prices rose, while MEG and Dated Brent prices fell. PX - naphtha spread decreased, PTA processing fee increased, and short - fiber and bottle - chip processing fees decreased [2] Trend Intensity - PX trend intensity is 1, indicating a relatively strong trend; PTA and MEG trend intensities are 0, indicating a neutral trend [7] Fundamentals - PX: Overseas refinery maintenance may lead to a continuous decline in gasoline and diesel inventories and strong cracking spreads until December. Domestic PX plants maintain high - level operation, but US and South Korean disproportionation units may cut production. The US - Asia window has opened, and domestic PTA plants face raw material supply shortages [7] - PTA: The extension of the maintenance time at Yisheng Ningbo and the commissioning of multiple new polyester plants have relieved the pressure of PTA inventory accumulation [7] - MEG: Although some devices have reduced production, new devices are being commissioned, and imports are expected to exceed 600,000 tons this month. Inventory continued to increase by 70,000 tons this Monday, and the polyester load will decline in December, resulting in an oversupply situation [8]
