Rubber Slips at Midday as Rally Loses Steam? Here’s What’s Keeping Prices in Check

Medan, August 13, 2026 – Natural rubber futures edged lower during Thursday’s (August 13) midday trading session after posting gains in recent days. The market appeared to lose upward momentum as profit-taking emerged, although the downside remained limited thanks to supportive underlying fundamentals.

As of 11:40 a.m. WIB (Indonesia Western Time), the RSS3 (RU) January 2027 contract on the Shanghai Futures Exchange (SHFE) was trading at 17,900 yuan per metric ton, down 40 yuan, or about 0.22%, from the previous session. Meanwhile, the SICOM TSR20 January 2027 contract in Singapore stood at 220.7 U.S. cents per kilogram, down 0.3 cent.

The pullback reflected a cautious tone across Asian rubber markets, as recent gains lacked fresh catalysts strong enough to sustain a broader rally.

Rally Losing Momentum, But No Sign of a Downtrend Yet

The midday decline is widely viewed as a healthy consolidation rather than the beginning of a bearish reversal.

Over the past several sessions, prices had been supported by declining rubber inventories in China and firmer raw material prices in some producing regions. However, as these bullish factors became largely priced in, investors opted to lock in profits while waiting for fresh developments on both supply and demand.

In other words, the market still has supportive factors, but not enough to trigger another strong leg higher.

Fundamentals Remain Well Balanced

On the supply side, global conditions have changed little.

Rainfall continues to disrupt tapping activities in parts of Thailand, particularly in the northeastern region, limiting raw material production. However, latex production in southern Thailand remains relatively normal, even though demand from processors has yet to recover significantly.

Vietnam has also experienced intermittent rainfall that temporarily disrupted tapping operations, but overall raw material availability remains adequate.

In China, continued rainfall in Yunnan has slightly tightened latex supply, prompting processors to become more active in securing raw materials. Meanwhile, weather conditions in Hainan have improved, allowing tapping operations to gradually resume and fresh latex supply to recover.

Overall, weather-related disruptions continue to provide price support, but they have not been severe enough to significantly alter the global supply balance.

Declining Chinese Inventories Continue to Support Prices

One of the key bullish factors remains the ongoing decline in China's natural rubber inventories.

As of August 9, 2026, China's total social inventory of natural rubber fell to approximately 1.155 million metric tons, down 14,000 tons, or about 1.2%, from the previous week.

Inventory declines were recorded across most rubber categories, including both dark-colored and light-colored rubber grades, suggesting that market demand continues to absorb available supply at a steady pace.

However, while shrinking inventories provide support, they have not been sufficient to trigger a fresh upward trend because production in major producing countries remains broadly stable.

Tire Industry Yet to Provide Strong Demand Boost

Demand fundamentals remain relatively subdued.

Several tire manufacturers that recently completed maintenance have resumed operations, leading to a gradual improvement in operating rates. Nevertheless, most producers continue to manage output cautiously as end-market demand has yet to fully recover.

Some manufacturers are still relying on promotional campaigns to support product shipments, indicating that raw material purchases remain focused on immediate production needs rather than inventory accumulation.

As a result, demand for natural rubber continues to improve only gradually.

External Factors Also Weigh on Sentiment

Broader macroeconomic developments have also influenced trading activity.

Weaker crude oil prices reduced overall support for commodity markets, including rubber. Meanwhile, stronger Asian equity markets helped cushion selling pressure, resulting in relatively narrow trading ranges.

The combination of these opposing forces has encouraged investors to remain on the sidelines while awaiting clearer market direction.

Outlook for Today's Trading Session

Based on current market conditions, natural rubber prices are expected to remain range-bound with a slightly bearish bias through the remainder of today's trading session.

The market continues to receive support from declining Chinese inventories and weather-related disruptions across some producing regions. However, global supply remains generally sufficient, while demand from the tire manufacturing sector has not strengthened enough to drive another sustained rally.

Unless new developments emerge—such as severe weather disruptions, major macroeconomic policy announcements, or a significant improvement in industrial demand—prices are likely to remain within a relatively narrow trading range.

Technical Outlook (Disclaimer)

Disclaimer: The following technical assessment represents a market opinion based on current price action and should not be interpreted as investment advice or a recommendation to buy or sell futures contracts.

Recent price movements suggest that bullish momentum is gradually fading after approaching short-term resistance levels. Selling pressure has increased modestly but remains insufficient to establish a confirmed downward trend. As long as key support levels remain intact, consolidation is expected to dominate near-term trading.

For today's session, the RSS3 January 2027 contract is expected to trade within a range of approximately 17,820–18,000 yuan per metric ton, with 17,850–17,900 yuan serving as the nearest support zone and 17,980–18,000 yuan acting as immediate resistance.

Meanwhile, SICOM TSR20 January 2027 is projected to fluctuate between 219.8 and 221.8 U.S. cents per kilogram. Holding above the 220-cent level would keep the consolidation scenario intact, while a decisive break below that level—particularly on stronger selling volume—could open the door for a deeper short-term correction.

Overall, the natural rubber market remains in a balanced phase. Declining inventories and weather-related supply concerns continue to provide underlying support, but stable production and still-muted demand from the tire industry are likely to keep further upside limited in the near term.
