Bullish Momentum Remains Intact! SICOM TSR20 Pulls Back Sharply in Early Trading, but the 235–240 US Cents/kg Target Remains Within Reach
Medan, June 4, 2026 – The global natural rubber market turned volatile again in Thursday morning trading. The benchmark July 2026 SICOM TSR20 contract on the Singapore Exchange (SGX) fell sharply to 231.3 US cents/kg as of 07:42 WIB (Western Indonesia Time), down 3.1 US cents from the previous session's close of 234.4 US cents/kg. The correction has raised a key question among market participants: Is the rubber rally beginning to lose momentum, or is this merely a temporary bout of profit-taking before prices resume their upward trend?
Based on the latest technical and fundamental developments, this morning's decline appears to have been driven primarily by short-term profit-taking following the market's exceptionally strong rally over the past two weeks. From a broader perspective, however, the bullish trend in the global natural rubber market remains firmly intact.
Historical data show that SICOM TSR20 has climbed from 181.7 US cents/kg at the beginning of January to 234.5 US cents/kg on June 2, 2026, representing a gain of more than 52 US cents, or approximately 29% year-to-date. Since trading around 216 US cents/kg at the end of April, prices have advanced almost uninterrupted, reaching this year's high of 234.5 US cents/kg earlier this week.
From a technical standpoint, such a rapid rally naturally increases the likelihood of profit-taking, particularly as prices approach the psychologically important 235 US cents/kg resistance level. The current pullback is therefore widely viewed as a healthy correction following the market's steep upward move.
Why Did SICOM TSR20 Decline This Morning?
Several factors appear to have contributed to Thursday's correction.
First, the market has begun pricing in expectations of higher production from Thailand and other major Southeast Asian producing countries. Rainfall has improved in several production areas after a prolonged period of hot weather, raising expectations that rubber supply could increase during June and July.
Second, many traders have started reducing long positions following the market's sharp rally since mid-May. When prices enter overbought territory, short-term corrections often occur even when the underlying fundamentals remain supportive.
Third, concerns are emerging that rapidly rising prices may begin to weigh on downstream industries, particularly tire manufacturers. Several research reports indicate that tire factory utilization rates have softened slightly, while inventories of finished products remain relatively high.
Even so, the current correction has not altered the market's primary bullish foundation, which continues to be supported by tight global supply conditions.
Global Supply Remains Tight
Several international commodity research institutions believe the rubber market has entered a "supply-driven market", where prices are influenced more by supply constraints than by demand weakness.
Thailand, the world's largest natural rubber producer, continues to face exceptionally high raw material prices. Thai cup lump prices have climbed to around 70–72 baht/kg, reflecting intense competition among processors for available raw materials.
Meanwhile, China's rubber imports and inventories across several major Asian trading hubs continue to decline. Inventories at Qingdao Port have also continued to trend lower, indicating that physical supply remains far from abundant.
Research from various market institutions also shows that Thailand's rubber exports to China declined sharply during the first four months of 2026, reinforcing the perception that global supply has yet to fully recover.
El Niño and Weather Risks Continue to Threaten Supply
Weather conditions remain one of the market's primary concerns.
Although rainfall has improved in some producing regions, traders are not yet convinced that production will recover immediately. Concerns over the lingering effects of El Niño remain significant, particularly as the industry approaches the main leaf growth and peak production period during the second half of the year.
Some analysts even argue that if rainfall becomes disrupted again between June and August, the market could face a more pronounced supply deficit during the third quarter.
Higher Oil Prices Continue to Support Natural Rubber
The recent rise in global crude oil prices has also contributed to the strength of natural rubber prices.
Geopolitical tensions, particularly in the Middle East, pushed oil prices higher and increased production costs for synthetic rubber. As a result, part of industrial demand has shifted toward natural rubber, including TSR20.
Vietnam has even reported domestic rubber prices reaching their highest levels in nearly a decade, supported by tight supply and growing market preference for natural rubber.
Technical Analysis: Market Could Retest 235–240 US Cents/kg
From a technical perspective, the broader trend in SICOM TSR20 remains firmly bullish.
Price action since January continues to display a consistent pattern of higher highs and higher lows. The 228–230 US cents/kg range has now become an important short-term support zone. As long as prices remain above this area, the potential for another rebound remains strong.
The nearest resistance lies at 235 US cents/kg. A decisive break above this level could pave the way for a move toward the 238–240 US cents/kg range during the week.
However, should selling pressure intensify and prices fall below 228 US cents/kg, the correction could extend toward the 223–225 US cents/kg range before the market establishes a new equilibrium.
Market Awaits Two Key Catalysts
Market participants are now focusing on two critical factors that are likely to determine the next direction of prices:
Actual rubber production across Southeast Asia during the second half of June.
The pace of inventory drawdowns in China's trading hubs and major port warehouses.
If production fails to increase as rapidly as currently anticipated while inventories continue to decline, the probability of SICOM TSR20 breaking above 240 US cents/kg will increase significantly.
Conversely, if supply expands substantially toward the end of June, the rally could begin to lose momentum and transition into a broader consolidation phase.
For now, most analysts continue to maintain a "cautiously bullish" outlook, viewing Thursday morning's correction as a temporary pause rather than the beginning of a broader reversal in the global natural rubber market.
