Report Summary 1) Report Industry Investment Rating - No information provided 2) Core Viewpoints - PTA: With the easing of the war between Iran and Israel, the crude oil market dropped significantly, and the chemical industry followed the decline. Despite the expectation of reduced downstream polyester load, the actual polyester output reached a new high. PTA will likely go through inventory reduction in the coming period, and the actions of major factories to increase the basis for sales have a significant impact on the market, making PTA spot supply tight. Polyester has recently achieved rapid inventory reduction [2]. - Ethylene Glycol (MEG): The conflict between Iran and Israel has eased, leading to a sharp decline in crude oil prices, and the chemical industry as a whole will follow suit. The rise in ethylene prices has strengthened the cost side, and the export of Iranian petrochemicals is expected to be affected. However, the overall import volume of MEG from Iran is limited. The profit of coal - based MEG has expanded, and the recent blockage of US ethane imports has affected domestic MEG plants. MEG will continue the inventory reduction trend, and the arrival volume will decrease. Polyester production cuts will have a certain impact on the market, and the inventory at ports has changed little. The recovery of the load of coal - based MEG plants will put pressure on the market, and MEG will enter the inventory reduction stage later [2]. 3) Summary by Relevant Catalogs Market Data - **Crude Oil**: INE crude oil price dropped from 498.5 yuan/barrel on June 27, 2025, to 496.7 yuan/barrel on June 30, 2025, a decrease of 1.8 yuan/barrel [2]. - **PX**: CFR China PX price increased from 868 to 874, and the PX - naphtha spread rose from 298 to 304.

Group 1: Methanol - High imports are materializing, and inventory accumulation has begun. The futures market is undervalued, waiting for the off - season expectations to be fully priced in. Iran has reduced its production, but there is an increase from non - Iranian sources and domestic supply. Overall, it is in a phase of bearish factors materializing. Pay attention to the actual inventory accumulation. With unstable macro - conditions and weak methanol prices in Europe and the US, it's hard to determine a clear direction for single - sided trading. Due to the low valuation, it is advisable to consider buying at low levels [1] - From June 17th to June 23rd, the power coal futures price remained at 801. The daily change in the Jiangsu spot price was - 10, the South China spot price was - 22, the Lunan converted price was + 18, and the Northwest converted price was + 33.

The non - standard price spread is neutral. The European and US markets are stable. The PDH profit is around - 1000, propylene prices are oscillating, and the powder production start - up rate is stable. The拉丝 production scheduling is neutral. In June, the supply is expected to increase slightly month - on - month. Currently, downstream orders are average, and raw material and finished - product inventories are neutral. In the context of over - capacity, the 09 contract is expected to face moderate to excessive pressure. If exports continue to grow or there are more PDH plant maintenance activities, the supply pressure can be eased to a neutral level [11] - From June 17th to June 23rd, the Shandong propylene price increased by 390, the East China PP price decreased by 30, and the number of warehouse receipts decreased by 13 [11] Group 4: Polyvinyl Chloride (PVC) - The basis has strengthened to 09 - 150, and the factory - pickup basis is - 420. Downstream start - up is seasonal, and there is a strong willingness to hold inventory at low prices. The mid - and upstream inventories are continuously decreasing. In summer, the northwest plants have seasonal maintenance, and the load is between the spring maintenance and the high production in Q1. In June, focus on the commissioning of new facilities and the sustainability of exports. Near - term export orders are decent. In June, pay attention to the Politburo meeting and the US interest - rate decision. Coal prices are weak, the cost of semi - coke is weak, and calcium carbide may have difficulty expanding profits as PVC plants undergo maintenance. The FOB counter - offer for caustic soda exports is 400. The comprehensive profit of PVC is - 500. Currently, the static inventory is at a high level but is continuously decreasing. The downstream performance is mediocre, and the macro - situation is neutral. Pay attention to exports, coal prices, commercial housing sales, terminal orders, and start - up rates [13] - From June 17th to June 23rd, the northwest calcium carbide price increased by 25, the Shandong caustic soda price decreased by 25, and other prices remained unchanged [12][13]

1. Report Industry Investment Rating No relevant information provided in the report. 2. Core Viewpoints of the Report - **Polyester Industry Chain**: The geopolitical situation in the Middle East has signs of escalation, and oil prices have rebounded significantly. However, under the expectation of weak supply and demand, there is also significant pressure for oil prices to continue rising. If there is no further positive news, oil prices may face a correction. PX supply has increased significantly recently, and the supply - demand margin has weakened, but it still has support in the short term. PTA's supply - demand margin has also weakened, but it has support at low levels. Ethylene glycol is expected to be weak in the short term. Short - fiber has a situation of weak supply and demand, and bottle - chip's supply - demand is expected to improve in June [2]. - **Methanol Industry**: The supply of methanol is generally in a loose pattern, and the demand side has a situation where MTO has mostly increased its load but downstream profits have deteriorated.

Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Report Core Viewpoints - **Methanol**: High imports are materializing, inventory accumulation is starting, and the futures price is undervalued. It's in a phase of negative factor realization. With an unstable macro - environment and weak methanol prices in Europe and the US, the unilateral price direction is hard to determine. Due to the low valuation, a long - position strategy at low prices is preferable [1]. - **Plastic (Polyethylene)**: The overall inventory of polyethylene is neutral. The 09 basis is around 0 in North China and +120 in East China. Import profits are around - 400 with no further increase for now. Non - standard HD injection prices are stable, and LD is weakening. In June, maintenance decreases and domestic linear production increases. Attention should be paid to LL - HD conversion and US quotes, as well as new device commissioning [6]. - **PP (Polypropylene)**: Upstream and mid - stream inventories of polypropylene are decreasing. The basis is +100, non - standard price differentials are neutral, and import profits are around - 500. Exports are good this year. In June, supply is expected to increase slightly, and downstream orders are average. Under the background of over - capacity, the 09 contract is under moderate to excessive pressure, which can be relieved if exports increase or PDH device maintenance increases [6]. - **PVC**: The basis has strengthened. Downstream has a strong willingness to hold inventory at low prices. Mid - and upstream inventories are continuously decreasing. In June, attention should be paid to new device commissioning and export sustainability. The current static inventory is decreasing from a high level, and downstream performance is average. Attention should be paid to factors such as exports, coal prices, and terminal orders [10]. 3.

Report Industry Investment Rating No relevant content provided. Report's Core View - Given the unclear outcome of the US - Iran negotiation, lack of clear OPEC production increase data, and the support from shale oil, it's not advisable to chase short positions even if the negotiation is successful. Short - term, it's better to stay on the sidelines for crude oil [1]. - For methanol, considering the ample supply and weak macro - environment, there may be a further decline. One - sided trading can focus on short positions on rallies, and for cross - variety trading, pay attention to the opportunity of going long on the 09 - contract PP - 3MA spread [3]. - For urea, with high supply and lukewarm demand, the price is expected to have no obvious trend. One - sided trading is recommended to stay on the sidelines [5]. - For rubber, it shows a strong - side oscillation. Short - term long or neutral thinking is recommended, with short - term operations and quick in - and - out. Also, pay attention to the band - trading opportunity of going long on RU2601 and short on RU2509 [9][11]. - For PVC, although the inventory decline is fast in the short - term, due to the expectation of strong supply and weak demand, the price is expected to oscillate weakly, but beware of the rebound if the weak export expectation is not realized [13]. - For polyethylene, the short - term contradiction has shifted from cost - driven to supply - driven decline. With no new capacity planned in June, the price may oscillate [15]. - For polypropylene, with planned capacity release in June and the approaching of the seasonal off - season, the price is expected to be bearish in June [16]. - For PX, the maintenance season is ending, the de - stocking is expected to slow down in June, and it will re - enter the de - stocking cycle in the third quarter. The price is expected to oscillate at the current valuation level [18]. - For PTA, it will continue to de - stock, and the processing fee is supported. The absolute price is expected to oscillate at the current valuation level [19][20]. - For ethylene glycol, the industry is in the de - stocking stage, but there is a risk of valuation correction as the maintenance season on the supply side is ending [21].

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the content. 2. Core Views of the Report Crude Oil - International crude oil futures prices have been rising, supported by a weakening US dollar and geopolitical risks. The supply - side OPEC+ production increase has alleviated concerns, but trade frictions suppress demand. After the holiday, the short - term trend depends on the US dollar, geopolitical situation, and supply - demand re - balancing. Unilateral trading can be in a slightly bullish direction, with WTI in the range of [59, 69], Brent [61, 71], and SC [440, 500]. Pay attention to the rebound opportunity of INE spreads and consider buying a straddle option to capture post - holiday volatility [8]. Styrene - In June, the supply - demand of styrene is expected to gradually become looser, and the price remains under pressure. However, due to tight spot circulation, the near - end price may fluctuate. It is advisable to take a short - selling approach [2]. Chlor - Alkali - For caustic soda, short - term spot prices remain strong. Before the fundamentals significantly weaken or warehouse receipts flow out, consider expanding the spread between the near - month and September contracts. For PVC, in the long - term, supply - demand contradictions are prominent. In June, supply pressure is expected to increase, and demand is weak. It is recommended to take a short - selling approach, with an operating range of 4500 - 5000, while also paying attention to macro - level disturbances [30][40]. Urea - The core contradiction of urea lies in high supply and weak demand expectations. Currently, supply is abundant, and demand is in a seasonal off - peak. After the Dragon Boat Festival, the market will test whether agricultural fertilizer procurement can start effectively. If not, it may further pressure the market [44]. Polyolefin - For plastics, there is an expectation of inventory reduction in early June due to increased maintenance and less imports. For PP, supply pressure will increase as maintenance ends. Demand lacks sustainability after a round of replenishment. Unilateral trading for PP can be short - biased at high prices, and the LP spread is expected to widen [46]. Polyester Industry Chain - **PX**: In June, PX supply - demand is expected to be tight, but may weaken after mid - June. It is expected to fluctuate at a high level. Consider short - selling at high levels, gradually exit the PX9 - 1 positive spread, and look for opportunities to narrow the PX - SC spread [50]. - **PTA**: In June, PTA supply - demand remains tight but may weaken in late June. It is expected to fluctuate at a high level. Consider short - selling at high levels and exit the TA9 - 1 positive spread at high prices [50]. - **MEG**: In June, the supply - demand structure of ethylene glycol is good, with inventory reduction expectations. Consider buying EG09 at around 4200 and taking a positive spread for EG9 - 1 [50]. - **Short - fiber**: In June, short - fiber supply - demand is expected to be weak. It is expected to fluctuate at a high level following the cost.
