1. Report Industry Investment Ratings There is no information provided regarding the report industry investment ratings. 2. Core Views of the Report Crude Oil - Overnight crude oil prices showed a strong - side oscillation, mainly driven by geopolitical uncertainties such as the ongoing conflict between Israel and Iran and the uncertainty of Trump's policies. Some in the market believe that the current oil price has factored in a risk premium of about $10, and potential supply disruptions may push the oil price to break through further. - From a macro and fundamental perspective, the Fed kept interest rates unchanged but anticipates two rate cuts this year, potentially stimulating the economy and boosting crude oil demand. Also, the largest decline in US crude oil inventories in a year last week supported the strong - side oscillation of oil prices. - In the short - term, the high - level oscillation trend is likely to continue, but market risks have increased. It is recommended to take a wait - and - see approach on the long side. Resistance levels are $75 - 76 for WTI, $78 - 79 for Brent, and 580 - 590 yuan for SC [51]. Methanol - Amid geopolitical conflicts, there is a strong sentiment for long - side allocation in the market. For ports, the import forecast has been revised down. If Iranian supply is interrupted, it may lead to the shutdown of supporting MTO plants or profit squeezing, potentially reducing production and alleviating the supply - demand contradiction at ports. It is necessary to monitor the situation in Iran and MTO dynamics. - In the inland area, prices have slightly weakened, with the increase driven by the futures market. On the supply side, plant restarts have led to an increase in production, while demand is in the off - season, limiting the room for valuation expansion. A short - term positive spread strategy is recommended [54]. Caustic Soda and PVC - For caustic soda, recent开工 has declined, and the capacity utilization rate in Shandong has dropped to 83%. Although some production may resume as costs decline, the driving force for caustic soda is limited. The main alumina plants in Shandong have continuously lowered their purchase prices, weakening the drive for the spot market. Non - aluminum demand is weak, and inventory is not an effective driving factor. The current caustic soda spot price is falling, and it is recommended to wait and see [57][58]. - For PVC, the short - term contradiction has not intensified further, and the price has strengthened due to the sharp increase in energy prices under geopolitical conflicts and the macro - sentiment. However, in the long - term, the supply - demand contradiction is prominent as the domestic real - estate sector is in a downward trend, dragging down terminal demand. With fewer maintenance plans in June and new plant startups in June - July, supply pressure is expected to increase. It is recommended to wait and see in the short - term and maintain a mid - term short - selling strategy [58]. Styrene - Market fluctuations mainly follow changes in crude oil and styrene futures. With downstream public tenders and low styrene inventory in commercial tanks, and the strong - side movement of oil prices, pure benzene's price only slightly followed due to its own supply - demand structure. Styrene port inventory has been declining, and spot supply is limited. Geopolitical factors have driven up crude oil prices, strengthening the near - term basis. Although integrated styrene plants have restarted, most of the supply is for contract fulfillment, resulting in limited market - flowing goods. - It is necessary to pay attention to the possible weakening of styrene's supply - demand balance due to high profits. Styrene's valuation is likely to be restored through price declines considering pure benzene's inventory and import pressure. It is recommended to wait and see in the short - term and look for short - side opportunities from the resonance of raw material prices in the medium - term [65]. Polyolefins (LLDPE and PP) - The sharp increase in oil prices has suppressed costs. Propylene and methanol have strengthened, while coal prices have shown a weak oscillation, compressing profits to a record low. Under the situation of weak supply and demand, inventory is differentiated (PP inventory accumulates, while PE inventory decreases). - Dynamically, there are many short - term PP maintenance plans, but new production capacity has been put into operation smoothly, leading to an increase in output. PE's start - up rate has increased, and more maintenance in mid - to late June may alleviate inventory accumulation. Demand is affected by the off - season and US tariffs, and the end of national subsidies at the beginning of the month has affected the demand for PP small household appliances. For PE, a positive spread strategy is recommended, and for PP, a mid - term short - side strategy can be considered, while paying attention to the start - up situation of marginal production capacity (MTO, PDH) [68]. Urea - The core drivers are the concentration of exports and the sentiment boost caused by international geopolitical events, which are demand - side dominated. The Israel - Iran conflict has pushed up international prices, and the expected increase in exports has stimulated domestic buying sentiment, driving both futures and spot prices to rebound. - Secondary drivers include the high daily production on the supply side with potential support from local maintenance and the short - term positive impact of inventory reduction. Although industrial demand is weak and the agricultural sector is cautious, it has not reversed the upward trend. A cautiously bullish approach can be maintained in the short - term, and long positions can be established at low levels based on the export and inventory reduction logic. However, strict risk control is required as the basis has narrowed after the rapid price increase, and the futures market has shown over - buying signals [76]. Polyester Industry Chain - **PX**: Middle - East geopolitical news has continued to affect oil prices, and the significant reduction of 1.1 billion barrels in EIA crude oil inventories has supported oil prices, which are expected to remain strong in the short - term. Although PX supply has increased recently and downstream factories have signaled production cuts, the market is worried about raw material supply due to the escalation of Middle - East geopolitics, and the short - term supply - demand of PX is relatively tight. PX09 is expected to be strong in the short - term; it is recommended to wait and see on the 9 - 1 month spread of PX; and reduce positions at low levels for the strategy of narrowing the PX - SC spread. - **PTA**: PTA supply has increased significantly recently, and downstream factories have signaled production cuts, so the supply - demand is gradually weakening. However, due to the tight spot circulation and the rigid demand replenishment of some polyester factories, the short - term basis of PTA is still strong, but there is an expectation of decline. Affected by the strong oil prices and the tight supply - demand of PX, PTA is expected to be supported strongly in the short - term. TA is expected to be strong in the short - term, pay attention to the pressure above 5000 yuan; look for reverse - spread opportunities above 200 for TA9 - 1. - **Ethylene Glycol (MEG)**: The supply - demand structure of MEG in June is still good. Although the supply of Saudi goods is expected to increase, the arrival of North American goods is limited, so both implicit and explicit inventories are expected to decrease. However, short - term demand is weak, and with the restart of MEG plants such as those in Saudi - China, Hengli, and Henan Coal Industry, the short - term supply - demand pattern is expected to be loose. Affected by the rising oil prices due to the Middle - East situation and the shutdown of some Iranian plants, MEG is expected to be strong in the short - term. Pay attention to the pressure around 4600 yuan for EG09 in the short - term. - **Short - fiber**: The current supply - demand of short - fiber is generally weak. Due to the strong backwardation structure of PTA, the spot processing fee of short - fiber has been significantly compressed. Short - fiber factories plan to cut production in July. With low inventory in short - fiber factories and strong raw materials, the absolute price of short - fiber is expected to oscillate strongly in the short - term, and the processing fee is expected to be restored. The strategy for PF is the same as that for PTA; focus on expanding the low - level PF processing fee on the futures market and pay attention to the implementation of production cuts later. - **Polyester Bottle - chips**: June is the peak season for soft - drink consumption. According to CCF, since the end of May, Sanfangxiang has shut down 1 million tons of polyester bottle - chip production capacity, and other major bottle - chip manufacturers also plan to cut production at the end of June and early July. The supply - demand of bottle - chips is expected to improve, and the processing fee may rebound from the bottom. The absolute price still follows the cost side. The strategy for PR is the same as that for PTA; the main - contract processing fee on the futures market is expected to fluctuate in the range of 350 - 600 yuan/ton, and look for opportunities to expand the processing fee at the lower end of the range [79]. 3.

Report Industry Investment Rating - The report gives a neutral rating to both PVC and caustic soda [4] Core Viewpoints - The supply - demand fundamentals of PVC are weak in the medium - to - long - term, lacking upward driving forces, and the price increase may not be sustainable. For caustic soda, the short - term trend follows the basis repair logic, but there is still room for compression of chlor - alkali comprehensive profit [3][4] Summary by Relevant Catalogs Market News and Key Data PVC - Futures price and basis: The closing price of the PVC main contract was 4,899 yuan/ton (+66), the East China basis was - 139 yuan/ton (-26), and the South China basis was - 39 yuan/ton (-26) [1] - Spot price: The East China calcium carbide - based PVC was quoted at 4,760 yuan/ton (+40), and the South China calcium carbide - based PVC was quoted at 4,860 yuan/ton (+40) [1] - Upstream production profit: The semi - coke price was 575 yuan/ton (+0), the calcium carbide price was 2,880 yuan/ton (+0), the calcium carbide profit was 130 yuan/ton (+0), the gross profit of calcium carbide - based PVC production was - 512 yuan/ton (-86), the gross profit of ethylene - based PVC production was - 561 yuan/ton (-41), and the PVC export profit was - 3.7 dollars/ton (+0.3) [1] - PVC inventory and operation: The in - plant PVC inventory was 39.7 tons (-0.2), the social PVC inventory was 35.5 tons (-0.7), the calcium carbide - based PVC operation rate was 80.45% (+0.55%), the ethylene - based PVC operation rate was 67.36% (-3.77%), and the overall PVC operation rate was 76.83% (-0.64%) [1] - Downstream order situation: The pre - sales volume of production enterprises was 63.8 tons (+1.2) [1] Caustic Soda - Futures price and basis: The closing price of the SH main contract was 2,298 yuan/ton (+25), and the basis of 32% liquid caustic soda in Shandong was 296 yuan/ton (-25) [1] - Spot price: The price of 32% liquid caustic soda in Shandong was 830 yuan/ton (+0), and the price of 50% liquid caustic soda in Shandong was 1,380 yuan/ton (+0) [2] - Upstream production profit: The single - variety profit of caustic soda in Shandong was 1,603 yuan/ton (+0), the comprehensive profit of chlor - alkali in Shandong (0.8 tons of liquid chlorine) was 819.5 yuan/ton (+80.0), the comprehensive profit of chlor - alkali in Shandong (1 ton of PVC) was 267.53 yuan/ton (+20.00), and the comprehensive profit of chlor - alkali in the Northwest (1 ton of PVC) was 1,264.03 yuan/ton (-141.52) [2] - Caustic soda inventory and operation: The liquid caustic soda factory inventory was 40.53 tons (+2.32), the flake caustic soda factory inventory was 2.85 tons (+0.06), and the caustic soda operation rate was 81.20% (+0.30%) [2] - Caustic soda downstream operation: The alumina operation rate was 80.87% (+0.52%), the dyeing operation rate in East China was 61.36% (-0.14%), and the viscose staple fiber operation rate was 80.56% (+0.00%) [2] Market Analysis PVC - Supply side: Due to ongoing previous maintenance, the overall PVC operation level decreased slightly month - on - month. Later, with reduced maintenance, production is expected to return. Supported by chlor - alkali profits, it is difficult to drive significant PVC production cuts. With the expected new capacity coming on stream from June to July, the PVC supply pressure remains high [3] - Demand side: The operation of downstream products decreased slightly, and the purchasing enthusiasm was low, continuing the weak domestic demand pattern. The PVC social inventory continued to decline month - on - month but at a slow pace. With increased supply and weak demand later, the social inventory may enter an accumulation phase [3] - Export: Export orders are being delivered steadily. There is no progress on the Indian BIS certification extension policy and anti - dumping policy. The sustainability of the export side needs to be monitored [3] - Price: Affected by the Middle East situation, the energy - chemical sector rose generally. Driven by market sentiment, both PVC futures and spot prices increased [3] Caustic Soda - Supply side: There are still many upstream device maintenance, mainly concentrated in North and East China. The operation in Shandong decreased month - on - month. However, due to good chlor - alkali profits, most upstream devices maintained high - load production. The overall caustic soda operation remains at a high level. With the expected new caustic soda capacity coming on stream from June to July, the supply pressure will further increase [3] - Demand side: The operation of the main downstream alumina increased slightly, and the restarted and newly - built capacities are gradually stabilizing. The spot price of alumina declined. A Shandong alumina plant maintained a high delivery volume and lowered the liquid caustic soda purchase price by 20 yuan to 800 yuan/ton ex - factory. Non - aluminum demand remains weak, with the dyeing operation rate declining month - on - month and the terminal operation of viscose staple fiber at a low level. Downstream buyers are cautious about high prices and mainly purchase for immediate needs [3] - Price: The current comprehensive chlor - alkali profit has fallen to a relatively low level. The futures are deeply discounted, and the spot price of caustic soda has decreased. In the short term, it follows the basis repair logic. However, the caustic soda factory inventory has risen to a relatively high level and is difficult to digest, and there is still room to compress the comprehensive chlor - alkali profit [3] Strategy - PVC: Neutral. In the medium - to - long - term, the PVC supply - demand fundamentals are weak, lacking upward driving forces. The price increase may not be sustainable. In the short term, it may maintain a volatile upward pattern. Adopt a strategy of shorting on rallies. Pay attention to the export side dynamics and new production progress [4] - Caustic Soda: Neutral. The short - term trend follows the basis repair logic. However, the caustic soda factory inventory has risen to a relatively high level and is difficult to digest, and there is still room to compress the comprehensive chlor - alkali profit. The later trend of caustic soda is expected to be under pressure [4]

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoint - Short - term: Maintenance in Shandong and other regions and rigid - demand procurement from alumina plants limit the downside space of caustic soda prices [9]. - Medium - term: From June to July, new production capacities such as Qingdao Gulf and Gansu Yaowang will be concentratedly put into production, and with limited demand growth, there is a strong expectation of supply - demand turning to surplus [9]. 3. Summary by Relevant Catalogs Price Group - On June 16, the closing price of the main caustic soda contract (SH2509) was 2,276 yuan/ton, down 0.35% from the previous trading day [6]. - For 32% ion - membrane caustic soda: In southwestern Shandong, the mainstream transaction price was 850 - 870 yuan/ton (slightly up from June 10, with a month - on - month increase of over 2% in early June according to the National Bureau of Statistics); in east - central Shandong, the mainstream transaction price was 860 - 930 yuan/ton, with some enterprises having tight supply due to maintenance; in northern Shandong, the mainstream transaction price was 880 - 940 yuan/ton, supported by the rigid demand of alumina plants; in southern Shandong, the mainstream transaction price was 880 - 900 yuan/ton, and the regional price difference narrowed [6]. - For 50% ion - membrane caustic soda, the mainstream transaction price was 1,360 - 1,460 yuan/ton, and the export quotation in East China was boosted by international demand [6]. Supply and Demand Group - Supply: This week, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 83.5%, unchanged from the previous week [7]. - Demand: In the alumina industry, the capacity utilization rate was 78.4%, a slight increase of 0.03 percentage points from the previous week; the operating rate of viscose staple fiber was 80.5%, down 0.15% from the previous week; the operating rate in the printing and dyeing industry in the Jiangsu and Zhejiang regions was 63.5%, up 0.27% from the previous week [7]. Inventory Group - As of June 12, the inventory of liquid caustic soda sample enterprises with a capacity of 200,000 tons and above in China was 378,000 tons (wet tons), down 1.07% from the previous week and up 4.2% year - on - year. The slowdown in inventory reduction reflects the weakening of demand resilience [7]. Profit Group - The profit of chlor - alkali in Shandong increased by 50 yuan/ton week - on - week, reaching 632 yuan/ton. The cost support came from the stable price of raw salt at 280 - 300 yuan/ton [8].

Report Industry Investment Rating - No information provided on the industry investment rating Core Views - For PVC, the medium - to - long - term supply - demand fundamentals are weak with insufficient upward drivers, but the current valuation is low, and the instability in the Middle East may boost the sentiment of the energy - chemical sector. Attention should be paid to macro - export policies and downstream demand recovery [3][4] - For caustic soda, the overall supply - demand fundamentals are expected to remain weak, with rising and hard - to - digest factory inventories. Attention should be paid to the sustainability of downstream replenishment [3][4] Summary by Related Catalogs Market News and Important Data PVC - Futures price and basis: The closing price of the PVC main contract was 4860 yuan/ton (+1), the East China basis was - 140 yuan/ton (-1), and the South China basis was - 40 yuan/ton (-31) [1] - Spot price: The East China calcium carbide - based PVC was quoted at 4720 yuan/ton (+0), and the South China calcium carbide - based PVC was quoted at 4820 yuan/ton (-30) [1] - Upstream production profit: The semi - coke price was 575 yuan/ton (+0), the calcium carbide price was 2880 yuan/ton (+50), the calcium carbide profit was 130 yuan/ton (+50), the calcium carbide - based PVC production gross profit was - 512 yuan/ton (-86), the ethylene - based PVC production gross profit was - 561 yuan/ton (-41), and the PVC export profit was - 4.0 US dollars/ton (-3.4) [1] - PVC inventory and operation: The in - factory PVC inventory was 39.7 tons (-0.2), the social PVC inventory was 35.5 tons (-0.7), the calcium carbide - based PVC operating rate was 80.45% (+0.55%), the ethylene - based PVC operating rate was 67.36% (-3.77%), and the overall PVC operating rate was 76.83% (-0.64%) [1] - Downstream order situation: The pre - sales volume of production enterprises was 63.8 tons (+1.2) [1] Caustic Soda - Futures price and basis: The closing price of the SH main contract was 2276 yuan/ton (+13), and the basis of 32% liquid caustic soda in Shandong was 380 yuan/ton (-76) [1] - Spot price: The price of 32% liquid caustic soda in Shandong was 850 yuan/ton (-20), and the price of 50% liquid caustic soda in Shandong was 1380 yuan/ton (-20) [2] - Upstream production profit: The single - variety profit of caustic soda in Shandong was 1665 yuan/ton (-63), the comprehensive profit of chlor - alkali in Shandong (0.8 tons of liquid chlorine) was 882.0 yuan/ton (-182.5), the comprehensive profit of chlor - alkali in Shandong (1 ton of PVC) was 310.03 yuan/ton (-132.50), and the comprehensive profit of chlor - alkali in the Northwest (1 ton of PVC) was 1405.55 yuan/ton (+0.00) [2] - Caustic soda inventory and operation: The liquid caustic soda factory inventory was 40.53 tons (+2.32), the flake caustic soda factory inventory was 2.85 tons (+0.06), and the caustic soda operating rate was 80.90% (-2.60%) [2] - Caustic soda downstream operation: The alumina operating rate was 80.87% (+0.52%), the printing and dyeing operating rate in East China was 61.36% (-0.14%), and the viscose staple fiber operating rate was 80.56% (+0.00%) [2] Market Analysis PVC - Supply side: Due to ongoing previous maintenance, the overall PVC operating level declined slightly month - on - month. With reduced future maintenance, production is expected to return. Supported by chlor - alkali profits, it is difficult to drive significant PVC production cuts. Coupled with the expected new production capacity coming on stream from June to July, the supply pressure of PVC remains high [3] - Demand side: The operating rate of downstream products declined slightly, and the purchasing enthusiasm was low, with the weak domestic demand pattern continuing. The PVC social inventory continued to decline month - on - month, but the destocking rate was slow. With increased supply and weak demand in the future, the social inventory may enter a restocking phase. Attention should be paid to the inflection point of PVC inventory. Export orders are being stably delivered, but there is no progress on the Indian BIS certification extension policy and anti - dumping policy. Attention should be paid to the sustainability of the export side [3] - Medium - to - long - term: The supply - demand fundamentals of PVC are weak, with insufficient upward drivers. However, the current valuation is low, and the instability in the Middle East may boost the sentiment of the energy - chemical sector. Attention should be paid to macro - export policies and downstream demand recovery [3] Caustic Soda - Supply side: There are still many upstream device maintenance, mostly concentrated in the North China and East China main regions. The operating rate in Shandong declined month - on - month. However, driven by good chlor - alkali profits, most upstream devices maintain high - load production. The overall caustic soda operating rate remains high, and there is an expected new production capacity coming on stream from June to July, further increasing the supply pressure [3] - Demand side: The operating rate of the main downstream alumina increased slightly, but the capacity return was not obvious after profit recovery, and the new production capacity in the second quarter was not fully released. The delivery volume of a Shandong alumina plant has returned to a high level, and the liquid caustic soda purchase price has started to be continuously reduced. Since June 17, it has been further reduced by 20 yuan to an ex - factory price of 800 yuan/ton, and the caustic soda spot price has also followed the decline. Non - aluminum demand remains weak, the printing and dyeing operating rate declined month - on - month, and the operating rate of terminals such as viscose staple fiber is at a low level. Downstream is cautious about high prices, and purchases are mainly for rigid demand, with continuous negative feedback on the demand side [3] - Cost side: The price of raw salt has fallen to a low level, and the power cost has decreased after the coal price reduction, so the cost support for caustic soda has shifted down [3] - Overall: The current comprehensive chlor - alkali profit is good, but the increasing factory inventory of caustic soda is difficult to digest. The overall supply - demand fundamentals of caustic soda are expected to remain weak. Attention should be paid to the sustainability of downstream replenishment [3] Strategy - PVC: Neutral. In the medium - to - long - term, the supply - demand fundamentals of PVC are weak, with insufficient upward drivers. However, the current valuation is low, and the instability in the Middle East may boost the sentiment of the energy - chemical sector. Wait for a rebound to short on rallies. Continue to pay attention to macro - export policies and downstream demand recovery [4] - Caustic Soda: Cautiously short for hedging. The current comprehensive chlor - alkali profit is good, but the increasing factory inventory of caustic soda is difficult to digest. The overall supply - demand fundamentals of caustic soda are expected to remain weak. Attention should be paid to the sustainability of downstream replenishment [4]

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the given reports. 2. Core Views Polyester Industry - PX: After the previous profit repair, supply has increased, and downstream polyester producers plan to cut production, leading to a weakening supply - demand balance. However, short - term support is still strong due to the restart of PTA devices and new installations. PX09 is expected to fluctuate between 6500 - 6900 yuan/ton [2]. - PTA: With the restart of previous maintenance devices and new installations, and the expansion of downstream polyester producers' production cut plans, the supply - demand balance is weakening. But considering the demand for PX and rising oil prices, the price has support at low levels. TA09 is expected to fluctuate between 4600 - 4900 yuan/ton [2]. - Ethylene Glycol: In June, the supply - demand structure is good, with limited import growth. Short - term demand is weak, and the market is expected to fluctuate between 4200 - 4450 yuan/ton [2]. - Short - fiber: The supply and demand are both weak. The processing fee has been repaired recently, but the repair space is limited. PF08 is expected to run between 6300 - 6700 yuan/ton [2]. - Bottle - chip: In June, the supply - demand situation is expected to improve, and the processing fee may rebound. The absolute price follows the cost [2]. Polyolefin Industry PP is bearish in the medium - term and can be used as a short - position allocation. PE has a weaker structure, and geopolitical conflicts may lead to a short - term rebound followed by short - selling. If oil prices fall, there will be more downward space [7]. Crude Oil Industry Oil price fluctuations are expected to increase due to concerns about supply disruptions caused by geopolitical issues. It is recommended to take a short - term bullish view. WTI's upper resistance is in the range of [79, 80] dollars/barrel, Brent's upper pressure is in the range of [80, 81] dollars/barrel, and SC's pressure level is in the range of [580, 595] yuan/barrel [10]. Urea Industry In the short - term, under high supply pressure, downstream demand has not yet connected well. The futures price may rebound due to the linkage of the energy - chemical sector, but the amplitude is limited by the fundamentals. It is recommended to wait and see [13]. Methanol Industry Imports and inland logistics have jointly pushed up port inventories. In the short - term, the inventory accumulation trend continues. It is necessary to track the situation in Iran and MTO dynamics. In the long - term, if Iranian supply is interrupted, it may push up the market sentiment, but downstream losses and high implicit inventories will restrict the spot price increase [15]. PVC and Caustic Soda Industry - Caustic Soda: Recently, the supply has decreased, and the demand is under pressure. There may be inventory pressure risks in the short - term. The 7 - 9 positive spread should be exited. In the medium - term, the far - month contract is looking for a bottom [18]. - PVC: In the short - term, it shows a volatile trend. In the long - term, the supply - demand contradiction is prominent due to the weak real - estate market. In June, supply pressure is expected to increase, and it is recommended to take a short - selling approach [18]. Styrene Industry Crude oil price increases have driven up the downstream product prices. Pure benzene has upward potential, but high inventory may limit the upside. Styrene's supply and demand have both increased weekly, and port inventory has decreased slightly. In the short - term, there is upward space, but there is medium - term fundamental pressure.

1. Report Industry Investment Rating - PVC: Neutral [4] - Caustic Soda: Cautious short - selling hedging [4] 2. Core Viewpoints - PVC has high supply and inventory pressure, weak domestic demand, and lacks positive support for its fundamentals, with limited upward driving force and limited downward space at the current low valuation. Attention should be paid to export - related macro - policies and downstream demand recovery [3][4]. - The overall supply - demand fundamentals of caustic soda are expected to remain weak, with acceptable comprehensive profits, slow inventory digestion, and large inventory pressure. Attention should be paid to the continuity of downstream replenishment and upstream maintenance dynamics [3][4]. 3. Summary by Relevant Catalogs Market News and Important Data PVC - Futures price and basis: The closing price of the PVC main contract was 4,810 yuan/ton (- 6), the East China basis was - 130 yuan/ton (+ 6), and the South China basis was - 10 yuan/ton (+ 16) [1]. - Spot price: The East China calcium carbide - based PVC was quoted at 4,680 yuan/ton (+ 0), and the South China calcium carbide - based PVC was quoted at 4,800 yuan/ton (+ 10) [1]. - Upstream production profit: The semi - coke price was 575 yuan/ton (+ 0), the calcium carbide price was 2,830 yuan/ton (+ 0), the calcium carbide profit was 80 yuan/ton (+ 0), the gross profit of PVC calcium carbide - based production was - 426 yuan/ton (+ 121), the gross profit of PVC ethylene - based production was - 520 yuan/ton (- 15), and the PVC export profit was 0.9 US dollars/ton (- 2.0) [1]. - Inventory and operation: The in - factory inventory of PVC was 39.8 million tons (+ 1.4), the social inventory of PVC was 36.1 million tons (- 0.1), the operation rate of PVC calcium carbide - based production was 79.90% (+ 4.19%), the operation rate of PVC ethylene - based production was 71.13% (- 0.58%), and the overall PVC operation rate was 77.47% (+ 2.87%) [1]. - Downstream order situation: The pre - sales volume of production enterprises was 62.6 million tons (+ 8.6) [1]. Caustic Soda - Futures price and basis: The closing price of the SH main contract was 2,324 yuan/ton (+ 16), and the basis of 32% liquid caustic soda in Shandong was 426 yuan/ton (- 16) [1]. - Spot price: The price of 32% liquid caustic soda in Shandong was quoted at 880 yuan/ton (+ 0), and the price of 50% liquid caustic soda in Shandong was quoted at 1,400 yuan/ton (+ 0) [2]. - Upstream production profit: The single - variety profit of caustic soda in Shandong was 1,759 yuan/ton (+ 0), the comprehensive profit of chlor - alkali in Shandong (0.8 tons of liquid chlorine) was 975.8 yuan/ton (+ 40.0), the comprehensive profit of chlor - alkali in Shandong (1 ton of PVC) was 463.78 yuan/ton (+ 0.00), and the comprehensive profit of chlor - alkali in the Northwest (1 ton of PVC) was 1,446.05 yuan/ton (+ 0.00) [2]. - Inventory and operation: The inventory of liquid caustic soda factories was 38.21 million tons (- 1.05), the inventory of flake caustic soda factories was 2.79 million tons (+ 0.06), and the operation rate of caustic soda was 83.50% (- 0.60%) [2]. - Downstream operation: The operation rate of alumina was 80.35% (+ 0.82%), the operation rate of printing and dyeing in East China was 61.50% (- 1.18%), and the operation rate of viscose staple fiber was 80.56% (- 0.04%) [2]. Market Analysis PVC - Supply side: There were few new upstream maintenance, the PVC operation rate increased month - on - month, the current output was at a high level in the same period, and it was difficult to drive significant PVC production cuts under the support of chlor - alkali profits. Coupled with the expected new production capacity coming on stream from June to July, the supply pressure of PVC remained high [3]. - Demand side: The overall downstream operation of PVC was weakly stable, with downstream markets mainly making rigid - demand purchases, and the weak demand situation was difficult to change [3]. - Inventory side: Downstream enterprises replenished stocks at low prices. The social inventory of PVC continued to decline month - on - month but at a slower rate, while the in - factory inventory increased. With the increase in supply and weak demand in the later period, the social inventory may increase slightly. Attention should be paid to the inflection point of PVC inventory [3]. - Export: Export orders were continuously and stably delivered. The extension policy of India's BIS certification expired at the end of June, and there was no progress in the policy at present. Coupled with the rainy season suppressing terminal demand, it was expected to drag down export demand [3]. Caustic Soda - Supply side: There were still many new maintenance plans in June. The 1.02 million - ton production capacity of Fujian Southeast Electro - Chemical was shut down for maintenance, and maintenance in Shandong also increased. The operation rate in Shandong decreased month - on - month. However, due to acceptable chlor - alkali profits supporting upstream manufacturers to maintain high - load production, the overall operation rate of caustic soda remained at a high level. Moreover, new caustic soda production capacity was expected to be put into operation from June to July, so the supply pressure on caustic soda remained high [3]. - Demand side: The delivery volume to the main downstream increased, and the current delivery volume exceeded the daily consumption. After entering the inventory accumulation stage, attention should be paid to the continuity of later - stage stockpiling. After the production profit of alumina was restored, new and restarted production capacities were gradually released, and the operation rate of alumina increased month - on - month, but the restart was not obvious yet. The purchase price of 32% caustic soda by major alumina manufacturers in Shandong was reduced by 10 yuan/ton to 830 yuan/ton since June 11, which may drag down the price of caustic soda. Non - aluminum demand was not good, the operation rate of printing and dyeing decreased month - on - month, downstream customers were cautious about high prices, and purchases were mainly for rigid demand [3]. - Cost side: With the decline in coal and electricity prices, the cost support for caustic soda decreased [3]. Strategy - PVC: Neutral. Given the continuous high supply and inventory pressure, weak domestic demand, and lack of positive fundamental support, the upward driving force of PVC is insufficient. At the current low valuation, the downward space is also limited. Attention should be paid to export - related macro - policies and downstream demand recovery [4]. - Caustic Soda: Cautious short - selling hedging. The overall supply - demand fundamentals of caustic soda are expected to remain weak, with acceptable comprehensive profits, slow inventory digestion, and large inventory pressure. Attention should be paid to the continuity of downstream replenishment and upstream maintenance dynamics [4].

Market Analysis - **PVC** - Supply side: There are few new upstream maintenance projects, the PVC operation rate has increased month-on-month, the current output is at a high level in the same period, and it is difficult to drive a significant reduction in PVC production under the support of chlor-alkali profits. Coupled with the expected production of new capacity from June to July, the PVC supply pressure remains high [3]. - Demand side: The overall downstream operation of PVC is weakly stable, and the downstream market mainly purchases based on rigid demand, with the weak demand situation difficult to change [3]. - Inventory side: Downstream enterprises replenish inventory at low prices, the social PVC inventory continues to decline month-on-month but the de-stocking rate slows down, while the in-plant inventory accumulates. In the future, with the increase in supply and weak demand, the social inventory may slightly accumulate. Attention should be paid to the inflection point of PVC inventory [3]. - Export: Export orders are continuously and stably delivered, but the extension policy of the Indian BIS certification expires at the end of June, and there is currently no progress in the policy. Coupled with the rainy season suppressing terminal demand, it is expected to drag down export demand [3]. - **Caustic Soda** - Supply side: There are still many new maintenance projects in June, with the 1.02 million-ton capacity of Fujian Southeast Electrochemical completely shut down for maintenance, and the maintenance in Shandong has also increased. The operation rate in Shandong has declined month-on-month, but due to the acceptable chlor-alkali profits, upstream manufacturers mostly maintain high-load production. The overall caustic soda operation rate remains at a high level, and new caustic soda capacity is expected to be put into production from June to July, so the supply-side pressure of caustic soda remains high [3]. - Demand side: After the continuous increase in the purchase price, the delivery volume of the main downstream has significantly increased, but when the delivery volume exceeds the daily consumption and enters the inventory accumulation stage, attention should be paid to the sustainability of future inventory stocking. After the repair of the alumina production profit, the new and restarted capacities are gradually released, and the alumina operation rate has increased month-on-month, but the restart is still not obvious at present. The non-aluminum demand performance is not good, the dyeing operation rate has declined month-on-month, and downstream customers are cautious about high prices and mainly purchase based on rigid demand [3]. - Cost side: With the decline in coal and electricity prices, the cost support for caustic soda has shifted downward [3]. Strategy - PVC: Adopt a neutral strategy. Due to the continuous high supply and high inventory pressure of PVC and weak domestic demand, the fundamental lack of positive support, and limited upward driving force, currently at a low valuation with limited downward space. Continue to pay attention to macro-export policies at the export end and the recovery of downstream demand [4]. - Caustic Soda: Adopt a cautious short-selling hedging strategy. Currently, the comprehensive chlor-alkali profit is acceptable, the inventory is being digested but at a slow speed, the inventory pressure is high, and the overall supply and demand fundamentals of caustic soda are still expected to be weak. Attention should be paid to the sustainability of downstream replenishment and upstream maintenance dynamics [4].

Report Industry Investment Ratings No relevant content provided. Core Views Crude Oil - Overnight oil prices rose due to macro - factors such as a weaker US dollar and optimistic sentiment from US - China trade negotiations. OPEC + production increased in May, but less than planned. The market is in a strong - side shock trend, suggesting a short - term long - bias approach. Resistance levels are given for WTI, Brent, and SC. Options can use a straddle structure [2]. Polyester Industry - PX: Supply has increased, but short - term downside is limited due to downstream demand and geopolitical factors. Strategies include short - term observation, 9 - 1 short - spread, and narrowing the PX - SC spread. - PTA: Supply - demand is weakening, but there is support at low levels. Strategies are to focus on the 4600 support and use a short - on - rebound approach, and 9 - 1 short - spread. - Ethylene Glycol: Supply is expected to remain low in June, with good supply - demand structure but limited upside due to weak demand. It is expected to trade in a range, and look for 9 - 1 long - spread opportunities. - Short - fiber: Processing fee recovery is limited, and absolute price follows raw materials. Strategies are similar to PTA and expanding the processing fee at low levels. - Bottle - chip: Supply - demand is expected to improve in June, and the processing fee is supported. Strategies are similar to PTA and expanding the processing fee at the lower end of the 350 - 600 yuan/ton range [6]. Chlor - alkali Industry - Caustic Soda: Recent decline is due to cost reduction. Supply has increased overall, but decreased in Shandong. Demand is supported by alumina. Inventory is accumulating in East China. Hold the 7 - 9 long - spread before price cuts or large - scale warehouse - receipt outflows. - PVC: Short - term is in a shock trend, but long - term supply - demand contradiction is prominent. Supply pressure will increase in June, and demand is weak. Adopt a short - selling strategy [11][16]. Styrene Industry - Short - term styrene may fluctuate, and mid - term pay attention to the bearish opportunity from raw material resonance. Downstream 3S profits have improved, and port inventory has decreased slightly, but supply may increase after plant restart [19][22]. PE and PP Industry - PE: Inventory is accumulating at the beginning of the month, with slight destocking in social inventory. Supply and demand are balanced in June, with limited up - and - down drivers. - PP: New capacity will be put into operation in June - July, and demand is in the off - season. There is a large inventory - accumulation pressure. Adopt a short - selling strategy at high prices [26][27]. Urea Industry - High supply is not matched by demand. Agricultural demand has slightly improved but lacks activity, and industrial demand is weakened by the decline in compound fertilizer production. Future trends depend on export policy and market sentiment. [33] Methanol Industry - Supply is abundant with high domestic production and expected high imports. Demand has increased in MTO but with poor downstream profits. Price should be traded in the 2200 - 2350 range, and pay attention to the transition from implicit to explicit inventory accumulation [35].
