1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **LLDPE & PP**: The overall trading was weak on Monday, and market sentiment deteriorated. For plastics, maintenance increased and some production shifted before early June, with low imports. Demand improved in the short - term due to tariff cuts, and there was an expectation of inventory reduction. For PP, the maintenance peak was in late May, and subsequent supply pressure would increase. Demand had short - term benefits but mid - term concerns. The static fundamentals were okay. For single - side trading, it was advisable to go short on rallies, and the LP spread was expected to widen [4]. - **PVC & Caustic Soda**: For caustic soda, in the short - term, supply pressure was limited during the concentrated maintenance period. Demand was supported by the potential resumption of some alumina production and new production lines. The purchase price of mainstream Shandong factories increased, and the futures price might rise further, but there were risks. It was recommended to stay on the sidelines, and aggressive investors could try positive spreads cautiously. For PVC, the short - term rebound was supported by macro - stimulation, export, and supply - demand factors, but there was an over - supply pressure in the long - term. It was expected to fluctuate in the short - term, with a resistance level of around 5100 for the 09 contract [26]. - **Polyester Industry Chain**: For PX, short - term supply was tight, and demand was supported, but the upside was limited. PX09 was expected to fluctuate in the range of 6600 - 7000, and PX9 - 1 was in a short - term positive spread situation. For PTA, the supply - demand situation was expected to weaken. TA09 was expected to fluctuate in the range of 4600 - 5000, and TA9 - 1 was short - term positive spread and medium - term negative spread. For MEG, there was an expectation of inventory reduction, and short - term support was strong. It was advisable to sell put options on EG2509 - P - 4300 and go for positive spreads on EG9 - 1. For short - fiber, the absolute price was expected to adjust, and attention could be paid to the opportunity to widen the processing margin. For bottle - chips, the absolute price followed the raw materials, and attention could be paid to the opportunity to widen the processing margin at the lower end of the range [30]. - **Crude Oil**: Oil prices were oscillating, and the future logic would shift from macro to fundamental factors. If OPEC's actual production increase was as expected, the market would be under pressure; otherwise, the pressure would be relieved. There was still a short - term geopolitical premium. Oil prices were likely to fluctuate within a certain range. The recommended trading strategy was a band - trading approach, with the WTI range at [59, 69], Brent at [61, 71], and SC at [450, 510]. It was advisable to buy volatility in options trading [34]. - **Methanol**: The port inventory showed an inflection point, and the expected increase in imports would lead to inventory accumulation and a weaker basis. The 09 contract was expected to decline in the short - term, and it was advisable to add positions at 2350, targeting 2050 - 2100. It was also advisable to reduce short - positions on the 69 reverse spread [37]. - **Styrene**: Styrene rebounded strongly. Tariff cuts improved demand expectations, and the inventory was at a low level. However, there were risks, including high inventory in the 3S products and weak pure - benzene supply - demand. It was expected to fluctuate in the short - term and be bearish in the medium - term. Attention could be paid to the resistance level of 7800 - 7900 for the near - month contract, and the opportunity for the EB - BZ spread to widen [42]. 3.

Report Industry Investment Rating - Not provided Core Viewpoints - PTA market: After the Sino-US economic and trade high-level talks, the atmosphere of bulk chemicals weakened, and the PTA market gave back some of the gains. Although downstream polyester manufacturers released remarks about production cuts, it is likely to adjust the output of polyester sub - products, and the impact on the PTA market is currently limited. The basis of PTA has strengthened significantly, and the market contango has emerged. Polyester factories' inventory has improved, and terminal export demand is expected to strengthen [2]. - MEG market: The port inventory of ethylene glycol in East China remains at over 700,000 tons. The inventory change is small. The load of coal - based ethylene glycol plants has recovered, putting pressure on the market, but coal prices have started to rise. The profit of coal - based plants has been compressed, and the mainstream plants are about to be overhauled, which will lead to the de - stocking stage [2]. Summary According to Relevant Catalogs Market Data - **INE Crude Oil and PTA - SC**: On May 15th, INE crude oil was 463.2 yuan/barrel, and PTA - SC was 1431.9 yuan/ton; on May 16th, INE crude oil was 456.2 yuan/barrel, and PTA - SC was 1458.7 yuan/ton, with a change of - 7.00 and 26.87 respectively [2]. - **PX**: CFR China PX decreased from 854 to 838, and the PX - naphtha spread increased from 264 to 273 [2]. - **PTA**: The PTA main futures price decreased from 4798 yuan/ton to 4774 yuan/ton, the spot price decreased from 5030 to 4990, the spot processing fee decreased from 390.3 yuan/ton to 438.8 yuan/ton, the disk processing fee increased from 158.3 yuan/ton to 222.8 yuan/ton, and the main basis decreased from 205 to 192. The number of PTA warehouse receipts increased from 69236 to 70046 [2]. - **MEG**: The MEG main futures price decreased from 4461 yuan/ton to 4460 yuan/ton, MEG - naphtha increased from (86.32) to (85.51), the MEG domestic price decreased from 4581 to 4570, and the main basis decreased from 95 to 85 [2]. - **Industry Chain开工率**: PX and PTA operating rates remained unchanged at 73.32% and 74.41% respectively, MEG operating rate decreased from 53.02% to 52.52%, and polyester load decreased from 91.34% to 91.14% [2]. - **Polyester Products**: POY150D/48F remained at 7050, POY cash flow increased from (35) to 3; FDY150D/96F remained at 7310, FDY cash flow increased from (275) to (237); DTY150D/48F increased from 8230 to 8245, DTY cash flow increased from (55) to (2); 1.4D direct - spun polyester staple decreased from 6805 to 6750, polyester staple cash flow decreased from 70 to 53; semi - bright chip decreased from 6045 to 6015, chip cash flow increased from (140) to (132). The sales of long - filament decreased from 35% to 28%, the sales of polyester staple decreased from 44% to 36%, and the sales of chips decreased from 40% to 36% [2]. Trade Negotiation Impact - Sino - US economic and trade high - level talks were held in Geneva, Switzerland from May 10th to 11th. Both sides agreed to establish a Sino - US economic and trade consultation mechanism, and the reciprocal tariffs were significantly reduced. 24% of the tariffs were suspended within the initial 90 days, and the right to impose the remaining 10% tariffs on these goods was reserved. The additional tariffs on these goods imposed by Executive Order No. 14259 on April 8, 2025, and Executive Order No. 14266 on April 9, 2025, were cancelled [2]. Device Maintenance - Due to the recent rapid rise in raw material prices, three major polyester filament manufacturers have decided to immediately implement production cuts for loss - making varieties and plan the next - step production cut plan, which will be implemented in the short term [2]

Core Viewpoint - The recent US-China trade talks have led to the cancellation of 91% of tariffs, with a temporary suspension of 24% reciprocal tariffs for 90 days, positively impacting the global trade environment and market expectations for oil prices [1] Industry Summary - The polyester industry chain shows strong performance across various products, with significant price increases observed: - PX509 contract closed at 6744 CNY/ton, up 272 CNY/ton (4.2%) - TA509 contract at 4774 CNY/ton, up 192 CNY/ton (4.19%) - EG2509 contract at 4460 CNY/ton, up 242 CNY/ton (5.74%) - PF507 contract at 6550 CNY/ton, up 286 CNY/ton (4.57%) - PR507 contract at 6082 CNY/ton, up 260 CNY/ton (4.47%) [1][1][1] - Global trade expectations are improving, with anticipation that Iran will release more oil, leading to fluctuations in oil prices [1] - The operating rates for PX have decreased due to some PX facilities reducing output, while PTA operating rates have slightly increased, resulting in a small rise in weekly production [1] - The polyester production rates have seen a slight increase due to higher operating rates in bottle flakes and short fibers, while short fiber inventory remains stable and long fiber inventory has generally decreased, indicating improved downstream demand [1][1] - The overall supply-demand fundamentals in the polyester industry chain are favorable, with a need to monitor the impact of the restart of PX and PTA maintenance facilities on the market [1] - Despite fluctuations in oil prices, the polyester industry chain's product prices continue to outperform crude oil, with production profits for PX and PTA showing significant improvement [1][1]
