Global Rubber Prices Begin to Lose Momentum, but the Uptrend Remains Intact: SICOM TSR20 Could Test a Critical Support Level This Week
Medan, May 26, 2026 – Global natural rubber prices are beginning to show signs of losing momentum after a strong rally that extended from April through mid-May 2026. However, the market has yet to exhibit signs of a sharp downturn, as underlying fundamentals continue to provide solid support, particularly from resilient tire demand and declining commercial inventories across key Asian trading hubs.
As of 7:20 a.m. WIB on Tuesday (May 26), the front-month SICOM TSR20 contract on the Singapore Exchange (SGX) for June delivery was quoted at 222.2 US cents/kg, down 0.9 cent from the previous session. Meanwhile, the most actively traded RSS3 September contract on the Shanghai Futures Exchange (SHFE) stood at 17,450 yuan per ton, slipping 5 yuan.
The latest price action suggests that the market is entering a consolidation phase following a prolonged rally since the beginning of the year. Historical data show that SICOM TSR20 climbed from 181.7 US cents/kg in early January to a peak of 231.6 US cents/kg on May 13, before trading more erratically within the 220-cent range.
The current correction is widely viewed as a loss of momentum rather than a major trend reversal. Prices continue to be supported by relatively low inventories, a supply recovery that remains incomplete, and steady demand from the global tire industry.
Tire Demand Continues to Support the Market
Global tire demand remains the most important factor preventing a deeper decline in natural rubber prices. Approximately 70% of the world's natural rubber consumption is used by the tire manufacturing industry.
In China, several tire producers have reported that although geopolitical tensions in the Middle East temporarily disrupted some export shipments, overall demand has remained relatively stable.
Additional support comes from China's automotive sector, which continues to expand. In April 2026, production of new energy vehicles (NEVs) reached approximately 1.32 million units, while sales totaled around 1.344 million units. China's vehicle exports also surged, with electric vehicle exports more than doubling compared with the previous year.
These developments continue to sustain demand for tire raw materials, helping preserve the fundamental strength of the rubber market.
Qingdao Inventories Continue to Decline
Another supportive factor has been the faster turnover of inventories at Qingdao, China's largest natural rubber trading hub.
Latest weekly data show that bonded warehouse inventories in Qingdao declined by approximately 4.23% week-on-week to 133,600 tons, while general trade inventories fell to roughly 575,300 tons.
The inventory drawdown indicates that physical distribution remains active. In other words, although aggressive buying in the futures market has begun to slow, actual consumption has not experienced a significant contraction.
Nevertheless, some analysts note that the pace of inventory reductions has moderated compared with early May, suggesting that the market may be entering a more balanced phase after earlier concerns over supply disruptions caused by hot weather and delayed tapping across Southeast Asia.
Supply Recovery Adds Seasonal Pressure
On the supply side, increasing production has become the primary source of downward pressure.
Rainfall has improved across major producing regions in Thailand, Vietnam, and Indonesia, allowing tapping activities to gradually recover. Production has also accelerated in Hainan and Yunnan, China's main rubber-growing provinces.
As a result, concerns over global supply shortages have begun to ease.
Earlier this year, the market rallied sharply due to dry weather and high temperatures associated with El Niño, which delayed tapping operations. Those weather-related supply concerns are now gradually giving way to seasonal bearish pressure as production improves.
The market is also paying close attention to weaker domestic tire demand in several countries. Producers of both full-steel and semi-steel tires continue to face elevated finished-goods inventories and only modest growth in export orders.
The latest data indicate that operating rates at full-steel tire factories in Shandong remain around 68%, while semi-steel tire plants are operating at approximately 75%. Finished tire inventories have also increased on a weekly basis.
Technical Analysis: The 220-Cent Zone Becomes the Key Battleground
From a technical perspective, SICOM TSR20 has entered a crucial phase after failing to sustain momentum above the psychologically important 230 US cents/kg level.
Price action since mid-May has formed a consolidation pattern with narrowing volatility, a development that often precedes the market's next directional move.
For the remainder of the week, the 221–223 US cents/kg range represents significant short-term resistance. Should prices fail to regain this zone, selling pressure could push the market toward initial support at 218–219 US cents/kg.
A break below that support would likely expose the stronger psychological support area around 215–216 US cents/kg. This zone is particularly important because it coincides with the early-May breakout level and aligns closely with medium-term moving averages.
As long as prices remain above 215 US cents/kg, the medium-term trend is generally considered to remain constructive rather than turning decisively bearish.
Conversely, fresh bullish catalysts—such as slower production growth in Thailand, a more aggressive decline in inventories, or a rebound in crude oil prices—could allow SICOM TSR20 to retest the 225–228 US cents/kg range.
Key Risks This Week: Thailand's Weather and Global Macro Sentiment
The market remains highly sensitive to two primary risk factors: weather conditions across Southeast Asia and broader global macroeconomic sentiment.
If excessive rainfall disrupts rubber tapping in Thailand, the market could once again price in a supply risk premium. Conversely, if production continues to recover normally through the end of May, additional selling pressure may emerge.
From a macroeconomic perspective, a stronger U.S. dollar and continued uncertainty surrounding the global economy remain important factors limiting gains across commodity markets, including natural rubber.
Even so, compared with many other industrial commodities, natural rubber continues to enjoy relatively stronger underlying support because global supply has not yet become abundant.
Outlook: Sideways to Slightly Lower, but Not Yet Bearish
For the short term through early June 2026, the market is expected to trade sideways with a mildly bearish bias, while volatility remains elevated.
Fundamentally, the market is being pulled in opposite directions by:
increasing seasonal production,
relatively resilient tire demand,
declining commercial inventories,
and fading speculative momentum following the prolonged rally.
Under these conditions, SICOM TSR20 is expected to trade within a range of 215–225 US cents/kg for the remainder of the week, with 215–218 US cents/kg representing the most critical support zone.
As long as this support holds, the current pullback is likely to be viewed as a healthy correction rather than the beginning of a major bearish trend.
