Group 1 - The article highlights President Trump's encouragement for oil tankers to navigate the Strait of Hormuz, asserting that there is no significant risk as Iran lacks a navy and has lost its ships [2][3] - Iran's new Supreme Leader, Mujtaba Khamenei, stated that Iran will not abandon its pursuit of revenge and will continue to use the blockade of the Strait of Hormuz as a tactic [3] - The Strait of Hormuz is identified as a critical global shipping route, with reports indicating that at least 16 vessels have been attacked in the Persian Gulf since military actions by the US and Israel against Iran [3] Group 2 - Iran's Deputy Foreign Minister, Lavanchy, mentioned that Iran permits certain countries' vessels to pass through the Strait of Hormuz, indicating a selective approach to maritime security [4]

Core Viewpoint - The article discusses the escalating tensions in the Strait of Hormuz, highlighting claims from U.S. officials about Iran laying mines, which Iran denies. The situation reflects ongoing military actions and threats in the region, particularly concerning oil and shipping security [1]. Group 1 - U.S. officials claim that Iran has begun laying mines in the Strait of Hormuz, while Iran denies these allegations [1]. - The U.S. Central Command reported that U.S. military actions have resulted in the destruction of over 90 Iranian naval vessels, including more than 30 mine-laying ships [1]. - Iranian Deputy Foreign Minister stated that Iran allows certain countries' vessels to pass through the Strait and has not laid mines in the waterway [1]. Group 2 - Iranian Supreme Leader Mujtaba Khamenei declared that Iran will not abandon its pursuit of revenge and will continue to use the blockade of the Strait of Hormuz as a tactic [1]. - Since the onset of military actions by the U.S. and Israel against Iran, at least 16 oil tankers, cargo ships, and other commercial vessels have been attacked in the Persian Gulf [1].

Core Viewpoint - The article discusses the heightened tensions in the Strait of Hormuz, where U.S. Navy has been reluctant to escort oil tankers due to the high risk of Iranian attacks, despite requests from shipping companies for protection [2][3]. Group 1 - U.S. President Trump stated that the U.S. military would escort oil tankers through the Strait of Hormuz if necessary, but this has not been put into action as the U.S. Navy has refused escort requests citing high risks [2]. - Since the outbreak of conflict, numerous commercial vessels have requested U.S. Navy escorts daily, but all requests have been denied due to the perceived threat from Iran [2]. - As of March 10, the assessment of risk for U.S. Navy escorts in the region remains unchanged, indicating a continued state of caution [2]. Group 2 - The Strait of Hormuz is currently experiencing a de facto blockade, with hundreds of vessels anchored nearby and only a few daring to pass through, resulting in approximately 10 ships having been attacked [3]. - A Thai cargo ship was reported to have been attacked in the Strait, with 20 crew members rescued and relocated to Oman [5].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - On March 10, the main contracts of PX, PTA, PF, PR, and MEG in the polyester industry chain fluctuated significantly, first dropping sharply and then rebounding with narrower declines. The main reasons were Trump's statement that the war was basically over and the G7's plan to jointly release crude oil reserves, which led to a significant adjustment in crude oil prices. However, releasing strategic reserves can only slow down the rise of crude oil prices, and the fundamental issue lies in the passage situation of the Strait of Hormuz. The war has not completely ended, and the Strait of Hormuz has not resumed normal navigation, so there is a need to be vigilant about the risk of repeated fluctuations in the market [1]. - In terms of fundamentals, due to the excessive market fluctuations recently, spot market transactions are still scarce, and the market is currently in a wait - and - see mood. Some factories still maintain a closed - market or suspended - shipment status, and there are still supply risks and hoarding phenomena. The market also shows differentiation due to the fundamentals and inventory conditions of each variety. If the cost - side prices remain high, attention should be paid to the possible negative feedback effects such as production cuts in the downstream [1]. - The market focus recently has been on the Iranian situation. Under the tense situation, crude oil prices have risen. In the PX market, the PXN was $355/ton (a month - on - month increase of $51.88/ton). Affected by the Iranian situation, the Strait of Hormuz traffic is still low. Under the concern of supply interruption, the PX spot structure has changed to a Back structure, and the floating price has become stronger. The PTA operating rate has increased, and the polyester load is being restored, so the demand for PX has further increased. At the same time, the PX supply problem has further intensified, and the PX load has decreased, with a larger inventory reduction [2]. - In the TA market, the PTA spot basis is - 15 yuan/ton (a month - on - month change of +0 yuan/ton), the PTA spot processing fee is 178 yuan/ton (a month - on - month increase of 7 yuan/ton), and the main contract's processing fee on the disk is 360 yuan/ton (a month - on - month decrease of 33 yuan/ton). The weaving and polyester loads are slowly recovering from a low level. After the centralized restart of PTA devices, the inventory reduction rhythm has been postponed, and inventory has continued to accumulate in March. However, supported by costs, the PTA trend is strong, and the processing fee has been compressed. Currently, the PTA basis is also rebounding, and the futures and spot markets are rising in resonance. In the long - term, as the cycle of concentrated capacity release ends, the PTA processing fee is expected to gradually improve, and the long - term outlook is still good [2]. - In terms of demand, the polyester operating rate is 84.1% (a month - on - month increase of 4.6%). After the Spring Festival, the polyester and weaving loads have been gradually recovering. The continuous rise in raw material prices recently has also driven some speculative demand and inventory reduction. The inventory pressure of polyester products is not large, and the short - term price increase is relatively healthy. Currently, the inventories of domestic and foreign textile and clothing are not high. Attention should be paid to the downstream restocking actions and the situation of textile and clothing export orders. After the digestion of the existing raw material inventory, it may also have a negative feedback effect on the downstream operating rate [3]. - In the PF market, the spot production profit is 168 yuan/ton (a month - on - month increase of 375 yuan/ton). The Middle East conflict has led to a sharp rise in oil prices, and the raw material prices have continued to soar. Direct - spun polyester staple fibers have quickly followed the price increase, but the increase is less than that of raw materials, and the processing margin of direct - spun polyester staple fibers has been compressed. The operating load of direct - spun polyester staple fibers is increasing. In the early stage of the price increase of staple fibers, the sales were active, and downstream customers stocked up intensively, and the factory inventory decreased. However, in the later stage, as the price reached a high level, the market entered a wait - and - see state [3]. - In the PR market, the bottle - chip spot processing fee is 622 yuan/ton (a month - on - month decrease of 173 yuan/ton). The price of polyester bottle - chips has risen significantly following the raw materials. In terms of fundamentals, after the Spring Festival, polyester bottle - chip devices have been restarted one after another, and the overall supply has increased slightly. The bottle - chip factories' shipments are relatively concentrated, and the inventory has decreased significantly. In the short term, the bottle - chip price increase is smooth, and the processing fee is expected to remain strong. Attention should be paid to the transaction situation after the continuous price increase [3]. 3.

德银将霍尔木兹局势划分为三类情景：若两周内重开，油价将回落至70美元区间；若维持当前的"模糊封锁"，油价将在80至 100美元波动；若演变为大规模布雷的"强制封锁"，导致OPEC增产失效，布伦特原油或飙升至200美元。哈尔格岛损毁程度 与封锁时长将成为研判未来的核心变量。 中东局势骤然升级，全球能源市场面临数十年来最大不确定性。据追风交易台消息，德意志银行在3月2日的报告中梳理了霍 尔木兹海峡走势的三种情景，其中最极端的全面封锁情景下，布伦特原油价格或向每桶200美元冲击。 伊朗最高领袖哈梅内伊在2月28日上午遇袭身亡。以色列方面称，哈梅内伊及其高级助手，包括伊朗国防委员会秘书阿里·沙 姆哈尼和伊朗伊斯兰革命卫队总司令穆罕默德·帕克普尔，均在空袭中丧生。随后媒体相继报道伊朗伊斯兰革命卫队 （IRGC）随即宣布封锁霍尔木兹海峡，并对驻扎在卡塔尔、科威特、阿联酋和巴林的美军基地实施打击。 油市对上述事件迅速作出反应。据彭博报道，多艘商业船只收到伊朗海军广播，称通行已被禁止，包括赫伯罗特（Hapag- Lloyd）和马士基（Maersk）在内的主要航运商已宣布暂停霍尔木兹海峡航行。OPEC+则宣布将在4月增产20. ...
