Global Rubber Prices Ease Today as Profit-Taking Weighs on Market Despite Persistent El Niño Concerns
Medan, September 2, 2026 – Global natural rubber prices retreated in Thursday's trading (Sept. 2), ending the rally that dominated the start of the week. The decline was largely driven by profit-taking after prices had climbed to their highest levels in several months. Despite the correction, market fundamentals remain relatively strong, supported by tight supplies due to adverse weather in major producing regions and growing concerns that the El Niño phenomenon could disrupt global rubber production.
As of 9:50 a.m. WIB (Western Indonesia Time), the SICOM TSR20 October contract was trading at 232.6 US cents per kilogram, down 2.5 cents from the previous close. Meanwhile, the active Shanghai Futures Exchange (SHFE) January 2027 contract stood at 18,670 yuan per tonne, a decline of 290 yuan from the previous session.
The correction followed a strong rally earlier in the week. On Monday (Aug. 31), SICOM TSR20 settled at 243 US cents per kilogram, marking its highest level of 2026. In China, domestic full rubber prices climbed to 18,350 yuan per tonne, up 100 yuan from the previous day, while Thai Mixed Rubber No. 20 remained unchanged at 17,850 yuan per tonne.
Still Higher Than a Week Ago
Despite today's pullback, rubber prices remain in an upward trend on a weekly basis.
According to Japan Exchange Group (JPX), the SHFE January 2027 contract gained around 1.7% during the week ended Aug. 28, while the active SICOM contract rose approximately 2.7%. Strong buying interest from both commercial participants and speculative funds pushed prices close to multi-year highs.
The performance suggests that bullish market sentiment remains intact, even as prices enter a consolidation phase.
Weather Continues to Support Prices
On the fundamental side, market attention remains focused on weather conditions across Southeast Asia.
Persistent rainfall in northeastern Thailand and China's Yunnan Province continues to disrupt latex tapping. Overnight rainfall has prevented farmers from harvesting latex efficiently, limiting daily production.
This has been reflected in firm raw material prices. Thailand's latex price increased to 78 baht per kilogram, while cup lump prices rose to 70.7 baht per kilogram. In China, latex prices in Yunnan increased to 16.9 yuan per kilogram, while Hainan prices reached 15.6 yuan per kilogram.
As long as weather disruptions continue, supply is expected to remain constrained, providing ongoing support to prices.
Qingdao Inventories Continue to Decline
Another supportive factor is the continued drawdown in China's rubber inventories.
As of Aug. 30, 2026, total natural rubber inventories in Qingdao stood at 627,700 tonnes, down approximately 3,800 tonnes, or 0.6%, from the previous reporting period.
The decline was mainly recorded in general trade inventories, while bonded warehouse stocks posted a slight increase. Overall, the downward trend suggests incoming supplies remain insufficient to fully meet industrial demand.
El Niño Remains a Key Market Concern
Beyond rainfall, market participants are increasingly monitoring the potential impact of El Niño, which is expected to strengthen in the fourth quarter of this year.
Analysts believe the weather phenomenon could bring hotter and drier conditions across major rubber-producing countries in Southeast Asia. Should this materialize, rubber tree productivity may decline further, tightening global supplies.
The market has also been supported by heightened geopolitical uncertainties, which have increased volatility across commodity markets, including rubber.
Demand Has Yet to Fully Recover
On the demand side, however, consumption has not strengthened at the same pace as prices.
Several tire manufacturers have slowed raw material purchases following the sharp increase in rubber prices over recent weeks. While production activity remains relatively stable, procurement has become more selective and is generally limited to immediate operational needs.
This indicates that the recent rally has been driven primarily by supply constraints rather than a significant improvement in end-user demand.
Investment Funds Remain Active
The market also continues to receive support from investment flows.
JPX estimates that Chinese commodity funds and speculative investors have accumulated around 800,000 tonnes worth of rubber futures positions across the SHFE and INE markets over the past two weeks. These investment inflows have been one of the key drivers behind the strong rally seen throughout late August.
Market Outlook
Fundamentally, the short-term outlook for the rubber market remains constructive. Weather-related production disruptions in Thailand and China's Yunnan Province, declining inventories in Qingdao, and growing concerns over the potential impact of El Niño continue to provide strong support for prices.
However, after the strong rally seen throughout late August, the market may remain in a consolidation phase as some investors continue to lock in profits.
Technical Analysis Disclaimer (Not Investment Advice): From a technical perspective, the active SICOM TSR20 October contract is currently trading around 232.6 US cents per kilogram. As long as prices remain above the 230–231 US cents/kg support zone, there is still potential for the market to retest the 236–240 US cents/kg range. On the downside, if selling pressure intensifies and prices fall below 230 US cents/kg, the correction could extend toward the 226–228 US cents/kg area. This technical outlook is based solely on historical price patterns and should not be interpreted as a guarantee of future market performance or investment advice.
Overall, the rubber market continues to be supported by relatively solid fundamentals. Although prices are under pressure today due to profit-taking, tight supply conditions in major producing countries are expected to remain the dominant market driver, limiting the downside risk in the near term.
