Rubber Prices Surge to 258.5 Cents at Midday, Rebounding After Yesterday’s Drop — What Is Driving the Rally?
MEDAN, September 30, 2026 — Natural rubber prices moved sharply higher again on Wednesday (30/9). After coming under heavy pressure in the previous session, rubber futures staged a strong rebound toward the end of the month.
Based on monitoring at 1:30 p.m. WIB, the October SICOM-TSR20 contract stood at 258.5 US cents/kg, up 8.5 cents, or around 3.4%, from the previous level. At the same time, the most-active January 2027 RU/RSS3 contract on the SHFE was around 19,900 yuan/ton, up 860 yuan.
The move suggests that the selling pressure seen in the previous session has not completely changed market sentiment. Instead, market participants have once again focused on several fundamental factors that continue to support rubber prices.
Strong rebound after selling pressure
Rubber's movement over the past two sessions shows that volatility has increased. In the previous session, the benchmark SHFE RU contract closed at 19,010 yuan/ton, down 265 yuan. The pressure was partly linked to profit-taking after the rapid rally, along with weaker tire demand as several Chinese tire manufacturers halted production for inspections and faced the upcoming extended holiday period.
However, conditions changed fairly quickly on Wednesday. The rise in SHFE toward 19,900 yuan and SICOM-TSR20 toward 258.5 cents indicates that buying interest has returned.
Therefore, for today's midday movement, profit-taking does not appear to be the only driver anymore. After the sharp correction, the market has once again focused on tight physical supply, weather disruptions and elevated raw-material prices in producing regions.
Thailand flooding becomes a factor to watch
Weather disruptions in Thailand have become an important factor for the rubber market. Flooding since mid-September has affected several areas of Thailand, including parts of the southern region.
Thailand is one of the world's major rubber-producing centers. Therefore, the issue is not simply flood damage, but whether rainfall and flooding are disrupting tapping activities, latex collection and raw-material distribution.
However, caution is still needed. There is not yet sufficient evidence to conclude that today's entire price increase is solely attributable to flooding in Thailand. Its impact on rubber production will depend on which production areas are affected and how long tapping activities are disrupted.
Thai raw-material prices also remain relatively high, indicating that cost pressures at the upstream level have not completely eased.
Thailand is not the only issue: global supply still faces disruptions
The latest ANRPC data provide an interesting picture. Global natural rubber production in July 2026 was estimated at only 1.321 million tonnes, down around 5.15% year-on-year, while July consumption was estimated at 1.297 million tonnes, up 0.8%.
ANRPC expects full-year 2026 production to increase by around 2.1%, but weather disruptions and supply uncertainty remain important factors.
This means the market is facing expectations of higher production as the industry enters a higher-production season, but actual supply does not necessarily increase immediately in line with expectations.
This is one reason rubber prices remain highly sensitive to weather-related developments.
Qingdao inventories remain a support factor
Another factor supporting prices is inventory development in China.
Rubber inventories in the Qingdao area remain on a downward trend. Recent data show a decline in natural rubber inventories in the area, although RU futures inventories have increased.
The decline in physical inventories indicates that actual rubber supply available in the market is not excessive. This is one reason the previous price correction did not immediately develop into a deeper decline.
But demand remains the weak point
On the other hand, the market has not yet received full support from the demand side.
Chinese tire manufacturers are approaching an extended holiday period, and some plants have reduced or suspended production. This is weighing on short-term rubber consumption.
This means the current rubber fundamentals have two sides.
On the supply side: weather disruptions, elevated raw-material prices and declining inventories provide support.
On the demand side: activity in the tire industry is tending to weaken ahead of the extended holiday.
Therefore, today's price increase is better viewed as a rebound supported again by supply-side factors, rather than evidence that all demand-related problems have been resolved.
China provides an additional sentiment boost
There has also been a modest improvement in China's macroeconomic picture. China's official manufacturing PMI returned above the 50-point level in September, indicating that manufacturing activity has returned to expansion territory.
For rubber, improving manufacturing activity is a positive sentiment factor because China is the world's largest natural-rubber consumer.
However, its impact on rubber consumption will not necessarily be visible immediately, particularly because the tire sector continues to face margin pressures and scheduled production stoppages ahead of the holiday.
What about SICOM-TSR20 through today's close?
From a technical perspective, the move to 258.5 cents/kg is important because the price has returned to, and even moved above, the previous peak area.
The monitoring data show:
September 22: 241.7
September 23: 249.5
September 24: 254.0
September 25: 256.2
September 28: 252.4
September 30 midday: 258.5
Therefore, 258–260 cents/kg is now a very important zone.
If the price can hold above 256–258, the rebound momentum remains relatively intact. The next areas to watch are around 260–262, followed by 264–266 cents/kg if buying pressure continues.
Conversely, if today's rally is again used by market participants to take profits, 256 becomes the initial support level. If that level fails, the price could retest 252–254 cents/kg.
Technical outlook for today
Upside scenario:
258.5 → 260 → 262 cents/kg
Correction scenario:
258.5 → 256 → 254 cents/kg
With momentum particularly strong during the midday session, the 256–262 cents/kg range can be used as a monitoring area through the close.
If the price manages to remain above 260, market attention will shift toward the possibility of testing higher levels. Conversely, if it falls back below 256, today's move could turn out to be a temporary rebound.
Disclaimer: The technical analysis above is based on price patterns and technical levels on SICOM-TSR20. It is not a definitive forecast or trading recommendation. Commodity prices can change rapidly due to weather, exchange rates, crude oil prices, Chinese policy, tire-industry conditions and geopolitical developments.
Fundamentals remain supportive, but the market is not without risks
Overall, the rise in SICOM-TSR20 to 258.5 cents/kg today appears to be a combination of a rebound following the previous profit-taking and renewed market attention to supply-side factors.
Flooding in several parts of Thailand has increased concerns over tapping and raw-material distribution, while Thai raw-material prices remain elevated. At the same time, rubber inventories in China continue to show a declining trend.
However, the market still faces demand-side headwinds, particularly from China's tire industry ahead of the extended holiday.
Therefore, today's rally does not automatically mean that prices will continue rising without a correction. In fact, after a gain of more than 3% in a single session, the risk of renewed profit-taking has increased.
The key point to watch toward the close is whether SICOM can maintain the 258–260 cents/kg area, or whether prices retreat again after the sharp midday rise.
If the level holds, the market will begin testing whether 260 cents/kg can turn from resistance into a new support level. If it fails, today's rise may prove to be more of a technical rebound than the beginning of a new upward wave.
