Report Industry Investment Rating No relevant information provided. Core Viewpoints of the Report - Polypropylene is in a phase of oscillating downward, and the later price center is expected to decline. The contract is pp2509. The Middle - East conflict has led to significant cost fluctuations, but from a fundamental perspective, over - capacity has further intensified the supply - demand pressure. In 2025, new device installations will continue throughout the year, with a concentrated release in June and July, increasing production pressure. Meanwhile, the existing production load remains stable. Supply is higher than in previous years, while demand is only slightly improved [1]. - Polyethylene is also in an oscillating downward phase, and the later price center is expected to decline. The contract is 12509. The Middle - East conflict has caused cost fluctuations, but fundamentally, the supply - demand situation remains weak due to over - capacity. In 2025, new device installations will continue throughout the year, resulting in huge production and sales pressure. The existing production load is acceptable, and supply is higher than in previous years, while demand is in a off - season [7]. - In the first half of 2025, although the prices of polyolefins declined as expected, the decline was not large compared to other chemicals. PP showed an oscillating downward trend, while L had a more fluent decline. In Q2, macro - factors such as trade wars and the Israel - Iran conflict dominated, causing polyolefins to fluctuate widely. Looking forward to the second half of the year, as the impact of trade wars and geopolitical issues fades, the focus may shift back to the fundamentals, which still feature high production and a balanced supply - demand situation. Overall, the market is expected to oscillate weakly, and cost disturbances such as those from crude oil and methanol need to be noted [8][9]. Summary by Relevant Catalogs 1. Market Review - Price: In Q1, polyolefin prices oscillated downward, with a significant decline at the beginning of the year due to increased supply pressure and a slowdown in downstream demand. In Q2, they fluctuated widely due to macro - factors such as trade wars and the Israel - Iran conflict. The 12505 contract rebounded due to strong demand for agricultural films in North China [8][14]. - Basis: In mid - January, the basis of polyolefins declined, especially for L. In February and March, the basis changed little. After late March, the basis trends of PP and L diverged, with PP's spot price being stronger and L's basis oscillating downward [14]. - Spread: The PF59 monthly spread showed an upward trend, especially in March and April, mainly reflecting the expected pressure from future production [14]. - Disk Spread: Since January, the L - P spread has been declining, mainly due to the alleviation of L's supply shortage after new device installations. After the Spring Festival, L strengthened again due to better downstream demand. In April, the L - PP spread further declined and then rebounded slightly [26]. - Methanol Price: Methanol prices have been weakening since January, but rebounded strongly after the Israel - Iran conflict, causing MTO profits to deteriorate [26]. 2. Supply Domestic Capacity Installation - PP: At the beginning of the year, it was expected that over 700 million tons of new devices would be installed, mainly in the first half of the year. In the first half of the year, a total of 2.855 million tons of 6 new devices were installed, slightly lower than expected, but the capacity pressure continued to increase. The main installation processes were oil - based (1.855 million tons) and coal - based (1 million tons) [47]. - PE: At the beginning of the year, it was expected that 5.8 million tons of new PE devices would be installed, with a relatively even quarterly distribution. In the first half of the year, a total of 3.03 million tons of new devices were installed, exceeding half of the plan. The installation progress was smooth, and the pressure of new installations will continue in the second half of the year. In the first half of the year, more standard - grade products were installed, while in the second half, non - standard products will be the focus [48]. Production - End Profits - Crude Oil: In Q1, crude oil prices first rose and then fell. The price increase in December was driven by increased heating demand and concerns about supply shortages. In January, prices started to decline due to factors such as the cease - fire agreement between Palestine and Israel. In Q2, prices fluctuated widely due to trade wars and the Israel - Iran conflict. The production profit of polyolefins from oil first recovered and then deteriorated, but the pressure on enterprises was not significant [62]. - Coal: High production and weak demand led to a decline in coal prices, resulting in good CTO profits [62]. - Methanol: Since late February, methanol prices have first rebounded and then declined, causing MTO profits to first deteriorate and then recover slightly, but overall profits were not good [62]. Domestic Production Volume and Load - PP: Since 2025, due to good production - end profits, enterprises have been more willing to start production, and the number of maintenance days was less than expected. With the high - load operation of existing capacity and the installation of new devices, PP production has continuously reached new highs. As of June, the total production volume was 19.4186 million tons, a year - on - year increase of 16.54%. All production processes, including oil - based, coal - based, and PDH - based, have increased production [102]. - PE: PE supply has also increased significantly, but production decreased in May due to increased maintenance. As of June, the total PE production volume was 16.1505 million tons, a year - on - year increase of 17.05%. The increase mainly came from LLD and LD products [110]. Import and Export - PP: As of May, the import volume was 1.3949 million tons, a year - on - year decrease of 5.17%, and the export volume was 1.3286 million tons, a year - on - year increase of 21.56%. The net import volume was 26,800 tons, a year - on - year decrease of 94.71%. Affected by the squeeze of domestic supply, the import - export pattern of PP has further reversed, and China has become a net exporter since March [125]. - PE: As of May, the cumulative domestic PE import volume was 5.9651 million tons, a year - on - year increase of 7.82%, and the export volume was 415,200 tons, a year - on - year increase of 7.79%. The cumulative net import volume was 5.5499 million tons, a year - on - year increase of 7.82%. The import - export of PE has both increased, and the pattern is relatively stable, but the reduction in imports caused by previous trade conflicts will start to be reflected in June [131]. 3. Demand PP Demand - In the first half of the year, demand was weak during the Spring Festival, but recovered quickly after the festival and entered the peak season in March and April. However, in Q2, demand from downstream industries gradually weakened, and export demand was affected by trade wars. In the future, as the off - season continues, market demand will remain weak [155]. PE Demand - PE demand has more obvious seasonal characteristics. In January, it was in the off - season, but after the Spring Festival, demand for agricultural films recovered, driving up prices. However, after April and May, demand declined as the agricultural film season ended [209]. 4. Inventory - PP Inventory: During the Spring Festival, inventory accumulated seasonally but less than expected. In March, inventory decreased due to high downstream demand. In Q2, inventory remained at a high level, reflecting the high - supply situation [221].
