SICOM TSR20 Pulls Back from the 230-Cent Level: Will It Retest 225 or Is a Rebound on the Horizon? Market Awaits Southeast Asia's Tapping Season
Medan, June 19, 2026 – Global natural rubber prices extended their decline in Friday morning trading. As of 08:18 WIB (Western Indonesia Time), the July 2026 SICOM TSR20 contract on the Singapore Exchange (SGX) was quoted at 226.0 US cents/kg, down 1.4 US cents from the previous close of 227.4 US cents/kg. At the same time, the most actively traded natural rubber contract on the Shanghai Futures Exchange (SHFE)—the September 2026 RSS3 contract—fell 240 yuan to 17,785 yuan per tonne.
The latest decline extends the correction that began after TSR20 reached 234.5 US cents/kg in early June. Over the past two weeks, market sentiment has shifted from concerns over tight supplies to expectations of increasing production as the tapping season progresses across Southeast Asia's major rubber-producing countries.
Intraday Trading Reflects Ongoing Consolidation
Intraday price action showed that TSR20 initially attempted to hold above 228 US cents/kg before gradually coming under selling pressure. Once that level failed to hold, prices slipped toward the 226 US cents/kg area.
Notably, the decline occurred alongside a reduction of approximately 369 lots in open interest. This suggests that the market was driven primarily by long liquidation—traders closing profitable long positions established during the rally toward 230 US cents/kg—rather than by a significant influx of new short positions.
In other words, the current pullback appears to reflect profit-taking and position adjustments rather than a sharp deterioration in market fundamentals.
From 181 to 234 US Cents/kg: A Correction After a Strong Rally
Despite the recent weakness, TSR20 has posted an impressive performance so far this year.
Prices climbed from 181.7 US cents/kg in early January to 234.5 US cents/kg on June 2, representing a gain of nearly 29% in just five months.
The rally was fueled by concerns over El Niño-related production risks, tight raw material supplies in several producing countries, relatively low inventories, and expectations of improving industrial demand.
Following such a strong advance, however, the market has entered a phase of reassessing supply prospects for the second half of 2026.
Why Is TSR20 Falling?
The main factor weighing on prices is the growing expectation of higher rubber production across Southeast Asia.
Recent market reports indicate that major producing countries have entered the seasonal period of increased tapping activity. As a result, traders are anticipating a rise in global natural rubber supplies over the coming weeks.
According to one international commodity research firm, raw material prices in Thailand have historically tended to decline during June as tapping activity accelerates. In some years, prices have fallen by as much as 10 baht/kg. Market participants are therefore closely watching whether this year's seasonal increase in supply will meet expectations or remain constrained by weather conditions.
Several additional factors are also contributing to weaker market sentiment:
China's tire industry has entered its seasonal period of softer demand.
Rubber inventories at Qingdao Port have stopped declining and are beginning to show signs of increasing.
Speculative funds are reducing exposure to agricultural commodities.
Japanese rubber futures have weakened alongside falling energy prices and softer sentiment across the broader commodity market.
Expectations of tighter global liquidity have prompted some investors to reduce exposure to higher-risk assets.
International market reports also suggest that Singapore's TSR20 futures have come under greater pressure than RSS3 contracts due to higher speculative participation in the TSR20 market.
Supply Is Improving, but Weather Risks Remain
Despite weaker short-term sentiment, the market has not yet turned decisively bearish.
Heavy rainfall in southern Thailand continues to disrupt tapping activities in several producing areas. Meanwhile, parts of Indonesia remain drier than normal. These uneven weather conditions suggest that actual production growth may fall short of market expectations.
In addition, raw material prices in producing countries remain relatively high, limiting the ability of processors to reduce export prices aggressively.
Market participants are also monitoring production trends in Africa, Cambodia, Laos, and Myanmar, where output has yet to increase as significantly as previously anticipated.
Beyond supply fundamentals, sustainability regulations are becoming increasingly important. Sri Lanka has recently launched a capacity-building program for its rubber industry to help producers comply with the European Union Deforestation Regulation (EUDR) and preserve access to European markets. The initiative highlights the growing importance of sustainability and supply-chain traceability in global rubber trade.
These factors explain why many analysts continue to maintain a neutral-to-positive medium-term outlook.
After Pulling Back from 230 US Cents/kg, What's Next?
From a technical perspective, 230 US cents/kg has now become an important psychological resistance after repeatedly failing to hold during recent sessions.
As long as prices remain below this level, the market is likely to remain in a consolidation phase while awaiting clearer evidence regarding supply conditions during the Southeast Asian tapping season.
Key technical levels include:
Support
First support: 225.0–226.0 US cents/kg
Second support: 222.0–223.0 US cents/kg
Major support: 220.0 US cents/kg
Resistance
First resistance: 228.0 US cents/kg
Second resistance: 230.0 US cents/kg
Major resistance: 234.5 US cents/kg
If expectations for stronger seasonal production continue to build while tire demand remains subdued, prices could retest the 225 US cents/kg area in the near term.
However, should this support hold and actual production in Southeast Asia prove lower than anticipated, the market could rebound toward the 228–230 US cents/kg range.
The Market Enters a Critical Test
The final two weeks of June are expected to be a decisive period for the global natural rubber market. Traders are now testing the central assumption that has weighed on prices—namely, that seasonal tapping will lead to a meaningful increase in supply.
If production expands in line with expectations, a correction toward 222–225 US cents/kg appears to be a realistic scenario.
Conversely, if adverse weather continues to limit production in Thailand and Indonesia while global inventories remain relatively low, the current pullback could prove to be only a temporary pause before the market attempts another move above 230 US cents/kg.
For now, the short-term outlook for SICOM TSR20 remains neutral to slightly bearish, while the medium-term bullish trend established since the beginning of the year remains intact. The market is still waiting for one crucial answer: How much additional rubber supply will actually emerge during Southeast Asia's tapping season this year?
