Rubber Prices Remain Capped as Tight Supply Meets Weak Tire Demand
Medan, September 22, 2026 — Global natural rubber prices are entering the final week of September with trading still fluctuating within a relatively high range. The market is facing two opposing forces: raw material supply remains less readily available amid weather disruptions and declining inventories, while demand from the tire industry is under pressure due to high production costs, weak sales, and planned production shutdowns during the long holiday period.
These conditions are limiting the upside potential for rubber prices. At the same time, supply factors and production costs are providing support, preventing downward pressure from developing into a sharp weakening trend.
Data from the Chinese market showed natural rubber prices at around 18,150 yuan per ton on September 20, only slightly higher than 18,125 yuan per ton at the beginning of September. During the period, prices reached a high of 18,866 yuan per ton, while the main Shanghai rubber futures contract had reached 19,810 yuan per ton, its highest level in nearly two years, before subsequently correcting.
Supply Has Not Fully Loosened
From a fundamental perspective, supply remains one of the main factors supporting prices.
ANRPC estimates global natural rubber production in 2026 at around 15.32 million tons, while consumption is projected at approximately 15.60 million tons, implying a potential deficit of around 280,000 tons for the year.
As Southeast Asia enters its peak production period, the release of raw materials has not proceeded as quickly as expected. Heavy rainfall in several producing regions has disrupted tapping activities, while aging trees and plant diseases in several producing countries have also affected raw material availability.
Rubber inventories in China have also shown a declining trend. As of September 13, rubber stocks in the Qingdao bonded zone and general trade channels stood at around 603,200 tons, down approximately 15,800 tons from the previous period. The decline in inventories is providing support for spot prices, although it has not yet been sufficient to push the market into a new uptrend.
Tire Industry Becomes a Drag on Demand
The biggest challenge currently facing the rubber market is coming from the downstream sector.
China's tire industry is entering a more difficult period amid high raw material prices and weak demand. Several tire manufacturers have begun scheduling production stoppages and maintenance ahead of the long holiday period, which is expected to push plant operating rates lower.
Data through mid-September showed all-steel tire operating rates at around 58–64 percent, while semi-steel tire operating rates also declined year-on-year. Relatively high tire inventories are prompting manufacturers to purchase raw materials based on short-term requirements rather than aggressively rebuilding stocks.
The pressure is also evident in China's tire industry performance during the first half of 2026. National tire production still grew by around 2 percent, but there was a clear divergence between the truck and bus radial (TBR) and passenger car radial (PCR) segments. TBR production increased, while PCR production declined and faced excess capacity pressure.
The China Rubber Industry Association (CRIA) said China's domestic passenger-car tire market has entered a period of destocking and restructuring. The addition of large amounts of PCR capacity over the past two years has intensified price competition, pressured distributor volumes and margins, and increased inventories across distribution channels.
China's Tire Exports: Volume Up, Value Under Pressure
Margin pressure is also evident in international trade.
In the first half of 2026, China's tire exports reached approximately 4.56 million tons, up 4.6 percent year-on-year. However, export value increased by only about 2 percent to US$10.88 billion.
This pattern indicates that growth in export volume has not been fully matched by growth in export value. Intensifying global competition and trade barriers are forcing manufacturers to contend with greater price pressure.
For the natural rubber market, this becomes a limiting factor because tire manufacturers have increasingly limited room to absorb aggressive increases in raw material prices.
Oil Prices Begin to Correct
Another factor that needs to be watched is crude oil prices.
Global oil prices are one of the external factors influencing rubber market sentiment because natural rubber competes with petrochemical-based synthetic rubber.
Market data showed the November WTI contract falling 1.81 percent to US$95.47 per barrel, while China's main crude oil futures contract fell around 2.6 percent to 734.8 yuan per barrel in overnight trading.
On the U.S. oil supply side, EIA data for the week ending September 11 showed crude oil production at 13.94 million barrels per day, down 10,000 barrels per day from the previous week. Crude oil inventories stood at 423.429 million barrels, down 640,000 barrels.
Oil price movements need to be monitored because changes in crude prices can affect the cost and competitiveness of synthetic rubber. When oil prices decline, cost pressures on synthetic rubber may also ease, potentially limiting the upside potential for natural rubber.
Tire Industry Enters Holiday and Maintenance Period
As September progresses toward the end of the month, China's tire industry is facing additional pressure from holiday schedules and plant maintenance.
Several manufacturers have announced plans to suspend production during the national holiday period. Some companies are scheduling shutdowns of around 10 days.
As of September 17, all-steel tire plant operating rates stood at 58.26 percent, down 3.99 percentage points from the previous week and 6.70 percentage points year-on-year. Meanwhile, semi-steel tire operating rates stood at 64.70 percent, also lower year-on-year.
China's rubber tire production in August stood at approximately 103.458 million units, down 0.3 percent from the same period a year earlier.
The decline in plant activity could reduce raw material purchases in the short term. However, production shutdowns could also reduce tire supply, meaning the impact on the rubber market is not entirely one-directional.
Uneven Pressure Across the Industry
Developments in China's tire industry show increasingly clear differences between segments.
TBR production increased by around 10 percent to 64 million units in the first half of 2026, while PCR production fell 1.7 percent to 220 million units. TBR plant utilization reached approximately 79.4 percent, higher than the 75.5 percent recorded for PCR plants.
TBR performance has been supported by the increasing penetration of new-energy heavy trucks in China and strong commercial vehicle markets in several countries. By contrast, the PCR segment is facing greater capacity pressure and more intense price competition.
This is important for the rubber market because raw material demand is determined not only by total tire production, but also by product composition, plant utilization, inventory levels, and sales conditions in each segment.
Tire Exports Face Price Pressure
Pressure is also evident in export trade.
China exported approximately 4.56 million tons of tires in the first half of 2026, up 4.6 percent year-on-year. However, export value increased by only about 2 percent to US$10.88 billion.
Among major CRIA member companies, export deliveries actually declined 1.4 percent to 141 million units. Export sales value fell 4.3 percent to 29.23 billion yuan, while inventories stood at approximately 29.23 billion yuan, down 0.9 percent.
The data indicate that growth in trade volume has not automatically translated into comparable growth in value. Global competition and trade barriers remain factors weighing on industry margins.
Rubber Prices Remain in a Consolidation Phase
Overall, the rubber market is currently experiencing a strong tug-of-war.
On one side, the supply-demand deficit, weather disruptions, declining inventories, and high production costs are providing a fundamental basis for price support.
On the other side, lower tire plant operating rates, relatively high finished-product inventories, weak vehicle demand, and intensifying competition in the tire industry are limiting the potential for a more aggressive price increase.
As a result, rubber prices are likely to maintain a high-range consolidation pattern in the short term rather than immediately entering a one-way uptrend.
From a technical perspective, natural rubber prices have fallen below the MA5, indicating that short-term bullish momentum is weakening. However, the MA10 and MA20 remain upward-sloping, suggesting that the medium-term structure remains relatively strong. The MA20 area is one of the key support levels to watch.
Outlook for This Week
For this week's trading, market attention is expected to focus on the ability of prices to hold support levels after correcting from previous highs.
Fundamentally, the potential for a sharp decline continues to receive support from supply conditions, while the upside remains constrained by weak demand from the tire industry.
Accordingly, the scenario to watch is sideways movement with relatively high volatility. If prices manage to break above and hold the nearest resistance area, the market could retest previous highs. Conversely, if key support is breached, the market could enter a further correction before finding a new equilibrium.
Oil prices, weather conditions in producing countries, raw material releases, Chinese inventories, tire plant operating rates, and purchasing activity before and after the long holiday period will be among the key indicators to monitor.
The technical analysis above is indicative and does not represent a certainty regarding price direction. Actual price movements will continue to depend on exchange conditions, supply and demand fundamentals, oil prices, weather conditions in producing countries, exchange rates, and developments in the tire industry.
