Overall, due to the overall decline in crude oil and aromatic hydrocarbon markets, the toluene market generally declined during the week.

Cost wise: The international oil price market has experienced a significant decline. As of April 11th, the settlement price of the main contract for WTI crude oil futures in the United States was $61.50 per barrel, and the settlement price of the main contract for Brent crude oil futures was $64.76 per barrel. On the one hand, the US tariff trade war and tariff trade barriers have had a huge impact on the global economy, increasing uncertainty in the future. The market believes that the risk of the United States falling into an economic recession has increased, and this will have a huge negative impact on global economic growth. On the other hand, the Organization of the Petroleum Exporting Countries and its allies (OPEC+) announced future production increases, which also had a negative impact on crude oil and led to a significant decrease in international oil prices.
Supply side:
Sinopec’s toluene enterprise is operating normally, with stable production of equipment and many products for personal use, resulting in stable production and sales. As of April 14th, East China Company quoted 5700 yuan/ton, North China Company quoted 5850 yuan/ton, South China Company quoted 5800-5900 yuan/ton, and Central China Company quoted 5850 yuan/ton.

Market forecast: Affected by the news of US tariffs, the overall commodity market will weaken, crude oil prices will decline widely, the atmosphere in the spot market will be weak, and the bearish sentiment in the aromatics market will be strong in the future. On the demand side, the downstream overall maintains on-demand procurement, but the demand is urgent. Overall, the toluene market is still under pressure, and it is expected that the market will mainly operate weakly in the short term.

The main regional liquid alkali market has experienced a decline, and non aluminum demand is high, so it is necessary to wait and see. The market demand is average.
Analysts from Shengyi Society believe that in recent times, the price of caustic soda has been declining, leading to significant inventory pressure on enterprises.

The main alumina enterprises are experiencing inventory pressure, and downstream demand is average. The comprehensive prediction of supply and demand game is that caustic soda will maintain a weak operating trend in the later stage, depending on downstream market demand.

Enterprises have a positive attitude towards shipment, while the upstream market is weak and downstream entry is mainly based on demand. The overall market support is insufficient, and it is expected that the price of ethyl acetate will remain stable and weak in the short term. Specific attention should be paid to changes in supplier facilities and downstream follow-up.
