SICOM TSR20 Briefly Hit 231.6 US Cents, But Quickly Plunged: Can It Hold Above 220 US Cents?

SICOM TSR20 Briefly Surged to 231.6 US Cents, But Quickly Slumped: Can It Hold Above 220 US Cents?

Medan, May 15, 2026 — The global natural rubber market turned highly volatile again after the benchmark SGX SICOM-TSR20 contract briefly surged to 231.6 US cents/kg on May 13, 2026, before quickly correcting to 222.3 cents/kg at the close of May 14. As of this morning at 07:43 WIB, the June contract was observed trading around 221.5 cents/kg, down about 0.8 cent. Meanwhile, the most active RSS3 September contract on SHFE fell sharply to 17,650 yuan/ton after previously breaking above the psychological 18,000 yuan/ton level.

The sharp movement indicates that the global rubber market is currently in a sensitive phase. On one hand, the broader trend remains bullish, but on the other hand, the market is beginning to show hesitation about sustaining an overly rapid rally above 225 cents/kg.

Market Previously “Tested” the 220 US Cent Level

Technically, the recent rise in SICOM-TSR20 prices has been quite interesting. Before eventually surging above 230 cents/kg, the market repeatedly tested the 220 cents/kg area as an important psychological level.

The 220 cents/kg area had previously been viewed as a confirmation point of whether the rally since April was genuinely strong or merely temporary. Once prices managed to break and hold above 220 cents/kg in early May, the market immediately responded with aggressive buying.

Successfully holding above 220 cents/kg strengthened confidence that the bullish trend remained valid. Speculative funds began entering the market more aggressively, leading to the next “test” at the 225 cents/kg area.

225 US Cents Reached, But Only Lasted One Day

After breaking above 220 cents/kg, the market moved very quickly toward 225 cents/kg and eventually peaked at 231.6 cents/kg on May 13, 2026. Interestingly, however, the level proved unsustainable.

Prices stayed above 225 cents/kg only briefly before facing massive selling pressure the following day. This phenomenon suggests that the market is not yet fully comfortable with excessively high valuations reached within such a short period.

Technically, this condition is often referred to as a “false breakout” — a breakout that lacks sufficient volume and fundamental support to continue rallying higher.

The market still appears to require consolidation before determining its next major direction. Many traders opted to secure profits because the rise from around 217 to 231 cents/kg occurred too rapidly within just a few days.

Southeast Asian Weather Remains the Main Driver

The earlier price surge was mainly triggered by concerns over supply disruptions from key Southeast Asian producers. Heavy rainfall in Thailand disrupted tapping activities and pushed raw material prices significantly higher. Thailand’s cup lump prices reportedly reached 68 baht/kg, while weekly latex production declined.

These conditions triggered aggressive buying by speculative funds anticipating tighter short-term supply. The market began building the perception that second-quarter production could face prolonged disruptions if weather anomalies continue through the end of May.

However, the market also realizes that the weather disruption may only be temporary. Production in Thailand, Vietnam, and Indonesia is expected to improve again entering June if weather conditions normalize.

Global Stockpiles Still Limiting the Rally

Although weather sentiment supports prices, the market remains overshadowed by relatively high global rubber inventories. Qingdao data as of May 10, 2026 showed total stockpiles at around 718 thousand tons.

The large inventory levels have prevented the market from fully believing that the world is facing a serious supply shortage. As a result, every sharp rally tends to be followed by aggressive profit-taking.

In addition, global tire industry demand has yet to experience major expansion. Raw material purchases remain largely routine rather than driven by large-scale production expansion.

Can SICOM TSR20 Still Hold Above 220 US Cents?

Technically, the chances of SICOM-TSR20 remaining above 220 cents/kg are still considered fairly strong in the short term. The area has now turned into the market’s primary psychological support after previously serving as an important resistance level.

As long as prices remain above 220 cents/kg, the medium-term bullish trend is considered intact. The higher high and higher low pattern since January 2026 also remains valid.

However, the market has now entered a more sensitive phase. If selling pressure continues and prices fail to hold the 220 cents/kg area, the potential for correction toward 216 to 212 cents/kg will become increasingly open.

Conversely, if the market manages to stabilize again above 225 cents/kg in the coming trading sessions, the opportunity to retest the 230 cents/kg area remains significant.

Middle East Tensions Still Providing Support

Apart from weather factors, the global rubber market is also being influenced by geopolitical tensions in the Middle East, particularly the conflict involving the United States and Israel against Iran, which has caused major disruptions in global energy markets.

These tensions have pushed global oil prices sharply higher in recent months due to concerns over potential disruptions to energy supplies through the Strait of Hormuz. Some international analysts even consider this crisis one of the largest energy disruptions since the oil crises of the 1970s.

For the natural rubber market, the impact is quite significant. When oil prices rise, synthetic rubber production costs also increase because petrochemical feedstocks become more expensive. This condition encourages parts of the tire industry to maintain natural rubber usage, thereby helping support SICOM-TSR20 prices.

In addition, rising energy costs increase logistics, transportation, and processing expenses in rubber-producing countries. This factor tends to encourage producers to withhold sales at low prices.

Nevertheless, the influence of Middle East tensions currently serves more as an additional supporting factor rather than the main engine of price increases. The global rubber market remains far more sensitive to Southeast Asian weather conditions, regional production levels, and Chinese demand.

Market Outlook

In the short term, the market is expected to remain volatile with a tendency toward consolidation within the 220–228 cents/kg range. The 220 cents/kg area has now become the key level that will determine whether the bullish trend remains strong enough or begins entering a deeper correction phase.

If adverse weather in Thailand continues through the end of May and Middle East tensions trigger another spike in global energy prices, the possibility of retesting the 230 cents/kg area remains open.

However, if production begins recovering in June and profit-taking pressure continues, the market may gradually weaken even though the broader annual trend still appears bullish.
