According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market has been weak and volatile recently (7.1-7.9). As of July 9th, the spot rubber market in China’s natural rubber market was around 13908 yuan/ton, a decrease of 0.14% from 13928 yuan/ton on the first day, and the high point during the cycle was 13983 yuan/ton. Downstream semi steel tire production has slightly decreased, providing weak support for rubber rigid demand; The slight decline in raw material prices, coupled with the continued increase in port inventories, still puts some pressure on the natural rubber market. As of July 9th, the mainstream price for 23 years of Guangken, Baodao, and Haibao latex in Qingdao is 13850-14150 yuan/ton.
As of July 9th, the price of Thai glue was 54.30 baht/kg, a decrease of 2.16 baht/kg from 55.50 baht/kg on July 1st. Currently, the natural rubber production areas in China and Vietnam have been fully cut off; Natural rubber producing areas such as Thailand and Indonesia have entered a period of increased production. The expected increase in global supply remains unchanged, and the price of natural rubber raw materials is expected to continue to decline in the later stage.
Recently (7.1-7.9), natural rubber inventories have slightly increased, which has a bearish impact on the natural rubber market. As of July 6, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 632400 tons, an increase of 0.03 million tons or 0.05% compared to the previous period.
Recently (7.1-7.9), the production of downstream semi steel tires has slightly decreased, providing essential support for the natural rubber market. As of July 4th, the production of semi steel tires by domestic tire companies has slightly decreased to around 7.0%; Around 6.40% of tire companies in Shandong have started construction on all steel tires.
Market forecast: As domestic and international raw material prices stabilize at high levels and expectations continue to decline in the later stage, downstream production fluctuates slightly, providing support for natural rubber demand, and Tianjin Rubber Port inventory remains high; Overall, it is expected that the natural rubber market will experience weak fluctuations in the later period.

According to the commodity analysis system of Shengyi Society, the market for locally refined petroleum coke fluctuated and rose in June. The mainstream average price of petroleum coke products from major domestic refineries was 2257.50 yuan/ton on June 30th and 2225.00 yuan/ton on June 1st, with a monthly increase of 1.46%.
Cost aspect: In June, the crude oil market prices experienced significant fluctuations, mainly due to the geopolitical situation in the Middle East. As the situation escalated and cooled down, crude oil prices correspondingly rose and fell sharply, with high volatility.
Supply side: In early June, the shipment of petroleum coke from local refineries was average, downstream procurement was cautious, refinery shipments were hindered, and petroleum coke prices continued to decline; In mid to late June, the shipment of petroleum coke from local refineries was good, and downstream procurement was active. In addition, some refineries had low inventory of petroleum coke, and the price of petroleum coke continued to rise. Some refineries’ prices fluctuated significantly with the indicators. In June, the transaction of petroleum coke at the port was average, with the main focus on destocking at the port, while downstream enterprises maintained their essential procurement.
On the demand side: In June, the domestic spot market for silicon metal # 441 showed an overall trend of first falling and then stabilizing. In the first ten days of June, after the Dragon Boat Festival, the spot market of metal silicon # 441 was running in a weak and downward direction. The downstream demand was slowly boosted, and the focus of market negotiation was adjusted downward. In mid to late June, the overall stability and consolidation of the spot market for silicon metal # 441 were the main factors, with little fluctuation in the spot market and a slight stalemate in supply and demand performance. The demand for petroleum coke market in the silicon industry still exists.

The market for medium sulfur calcined coke remained stable in June, with an overall increase in the cost of petroleum coke. However, the price of medium high sulfur calcined coke was affected by negative demand, and most companies’ quotations remained stable.
Aluminum prices were relatively strong in June. From a fundamental perspective, currently in the off-season of traditional consumption in China, domestic demand is relatively weak, and aluminum prices are relatively high, resulting in insufficient downstream purchasing and receiving enthusiasm; On the supply side, the operating capacity of electrolytic aluminum is unlikely to decrease during the southwest rainy season, but the probability of maintaining a weekly output of 844000 tons is relatively high, and the supply is relatively stable. From a cost perspective, the stabilization of raw material alumina has led to short-term strength, which may provide relative support for aluminum prices in the near future. Downstream aluminum uses carbon as the main demand in the petroleum coke market.

Market forecast: Currently, trading in the petroleum coke market is still acceptable, and downstream demand procurement still provides support for the petroleum coke market. It is expected that petroleum coke will mainly consolidate in the near future.
