Outlook for the future

After several intraday surges, oil prices ultimately retreated, closing with a long upper shadow. Financial markets are increasingly shifting their attention to the upcoming tariff policy announcement by Trump, entering a risk-off mode with evident wait-and-see sentiment. For crude oil, geopolitical factors continue to influence the market. In the previous trading session, Trump's threats against Iran and Russia drove oil prices to rise more than expected. The uncertainty stemming from various factors has made investors more cautious in their participation.

From a geopolitical perspective, Iran's strong response to Trump's "bombing threat" has heightened market tensions. The U.S. continues to advance sanctions against Iran, with the Department of Defense deploying additional air power to strengthen its military posture in the Middle East. The U.S. has sent a second aircraft carrier to the region. Meanwhile, regarding Trump's statement that Russian President Putin was "very angry," Russia has expressed its inability to accept the current U.S. stance, as it fails to address Moscow's concerns about resolving the root causes of the crisis.

In addition, sources said that eight OPEC+ countries that have volunteered to cut production will hold a meeting on Thursday. Early API weekly data showed a significant build-up of 6.03 million barrels of crude oil, far exceeding market expectations, which could help alleviate supply concerns to some extent. With many influencing factors recently and facing multiple variable choices, high oil price volatility will remain the norm; note要做好风险管理，谨慎参与。 It seems like there is a part in your text that did not get fully translated.

IV. Today's Market Forecast

PE: In terms of raw materials, the crude oil market may be affected by multiple factors. It is necessary to pay attention to changes in crude oil supply, U.S. tariff policies, geopolitical situations, and adjustments to OPEC+ policies for their impact on international oil prices. On the supply side, although there are expectations of new plant startups, the production increase will be limited in the short term, and overall supply is expected to remain relatively stable. However, it is necessary to continuously monitor the progress of new plant startups and the impact of changes in the international situation on imports. On the demand side, there is expected to be a marginal increase in demand from downstream sectors such as agricultural mulch films, packaging materials, and construction materials. However, factors such as overseas tariff hikes may limit the extent of growth to a certain degree. Overall, the polyethylene market is expected to consolidate within a range in the short term.

PP: On the raw material front, the crude oil market may be influenced by multiple intertwined factors, and attention should still be paid to changes in crude oil supply, U.S. tariff policies, geopolitical tensions, and adjustments to OPEC+ policies, among other factors affecting international oil prices. On the supply side, there are currently no plans for changes to PP plant operations before the holiday, and the impact of PP plant shutdowns remains relatively high. It is expected that supply pressure in the market will be moderate, although polyolefin inventories at the two major oil companies have accumulated, leaving destocking pressure unresolved. On the demand side, PP demand before the holiday is likely to remain driven by rigid procurement, with limited new orders from downstream sectors and cautious purchasing sentiment. Although downstream operations are gradually ramping up, overall demand release remains slow. In summary, the polypropylene market is expected to experience upward consolidation in the short term.

From a supply and demand perspective, the operating rate of chlor-alkali facilities remains high. The expectation of maintenance, which had been anticipated over time, has gradually diminished. Additionally, there are no major maintenance plans expected in the near term, keeping PVC supply relatively stable at a high level. For chlor-alkali companies, although PVC is individually loss-making, the profit situation for caustic soda is quite good. In terms of PVC downstream demand, it is currently only maintaining essential purchases, and after the price increases in both the spot and futures markets, downstream buyers have become less active, tending to place low bids for inventory replenishment. There are insufficient variable factors from the supply and demand side to drive prices. On the policy front, there were no significant directional influences in the first quarter, and given the tone of the real estate sector, PVC is unlikely to perform well. It is expected that in the short term, the spot market for PVC will continue to maintain a narrow range of adjustments. The current spot price for calcium carbide method No. 5 type PVC in East China is within the range of 4800-5000 yuan/ton.
