Weather Disturbances in Vietnam Disrupt Supply Chain
Recently, weather conditions in the main production areas of Southeast Asia have once again become a key factor affecting the natural rubber market. Vietnam has been impacted by Typhoons "Kammuri" and "Kalmaegi," resulting in heavy rains that have interrupted tapping operations, leading to a short-term production below expectations. Industry estimates suggest that the production loss due to this weather disturbance is around 3,000 to 5,000 tons. Although this represents a limited portion of overall production, it has supported market sentiment. If the weather clears, this capacity could still be released.
Meanwhile, the supply situation in Thailand remains relatively stable. The prices of cup lump and latex continue to rise slightly, reflecting increased cost support from the raw materials side. The Thai Rubber Authority announced plans to export zero-tariff rubber to China via the Mekong River, with the first commercial shipment expected to commence in September this year and expanding production gradually through 2025, introducing a new variable to the mid-to-long-term supply.
Performance and Inventory Status in Domestic Production Areas
Domestically, rainfall in the Yunnan production area is gradually weakening, but Hainan has experienced more significant precipitation due to the typhoon, impacting the tapping pace. The short-term tightening of overall supply is evident.
On the inventory front, as of August 24, domestic social inventories of light and dark rubber both slightly declined to 473,000 tons and 797,000 tons, respectively, a decrease of about 1%. The slight reduction in social inventories, combined with tight raw material supplies, provides some support for prices. However, in the futures market, inventories of natural rubber and RSS3 continue to increase, indicating short-term delivery pressure cannot be ignored.
Demand-side Challenges: Tire Industry under Pressure
Demand performance varies. The operation rate of tire factories has recently decreased, with all-steel tire inventories remaining relatively stable, while semi-steel tires continue to accumulate. As export orders deplete, many are hoping that the "Golden September and Silver October" peak season will materialize. However, based on the pace of orders, terminal consumption recovery remains unclear.
Although some factories in the concentrated latex product industry have seen order improvements, overall boosts remain limited. The lack of cohesion in manufacturing demand results in weak upward price momentum.
Price Differences and Market Signals
As for price trends, the price gap between RU and NR continues to widen, reaching 3,165 yuan/ton as of August 29, highlighting further structural differences between domestic and foreign markets. The spread between the September and January contracts also widened to -975 yuan/ton, indicating continued cautious short-term market expectations. The non-standard spread remains at -1,060 yuan/ton, with overall volatility limited.
This suggests that the market remains in a wait-and-see mode concerning future trends. Although short-term supply disruptions and cost support provide a baseline, uncertainty on the demand side makes it difficult for bulls to achieve sustained breakthroughs.
Increased Volatility Remains the Main Theme
Looking ahead, natural rubber prices may continue to exhibit a volatile and slightly bullish trend in the short term, mainly due to the weather disturbances in Southeast Asia and the gradual reduction in domestic social inventories. However, in the longer term, the recovery of the tire industry and the global trade environment will determine whether rubber can form a substantial upward trend.
Industry insiders indicate that if the "Golden September and Silver October" peak season fails to bring significant demand improvement, and overseas supply gradually recovers once the weather stabilizes, rubber prices may face renewed pressure. Conversely, if demand side takes off fueled by policy support, the market could see a temporary breakthrough.
