Rubber Prices Rebound as Market Sentiment Improves, Though Further Gains May Be Limited

Medan, August 19, 2026 – The natural rubber market rebounded on Wednesday (August 19) after a brief pullback in the previous session. Shanghai Futures Exchange (SHFE) rubber futures climbed to around 18,300 yuan per ton, up approximately 0.74%, supported by improving market sentiment, firmer raw material prices, and continued confidence in the market's underlying fundamentals.

The rebound follows Tuesday's decline, which was widely viewed as a round of profit-taking after the market's rally since early August rather than a reflection of deteriorating market fundamentals.

In the spot market, China's domestic RSS remained stable at around 17,350 yuan per ton, while Thailand's TSR20 mixed rubber held steady at approximately 17,060 yuan per ton.

Supply Remains Stable, but Weather Risks Persist

On the supply side, market participants continue to monitor weather conditions across Southeast Asia, the world's primary natural rubber-producing region.

Frequent nighttime rainfall in Thailand has continued to disrupt tapping activities, keeping raw material prices elevated. Thai latex prices rose to approximately 74.5 baht per kilogram, while cup lump prices reached around 67.5 baht per kilogram. Similar wet weather in Indonesia, Malaysia, Vietnam, and China's Yunnan Province has also constrained latex production.

However, despite localized disruptions, there have been no major weather events severe enough to significantly reduce overall production. Global supply therefore remains broadly stable.

As a result, while higher raw material costs continue to provide price support, the market still lacks a sufficiently strong supply-side catalyst to trigger another sharp rally.

Inventories Continue to Decline

Another supportive factor is the ongoing decline in inventories.

As of August 16, 2026, total natural rubber inventories at Qingdao Port stood at approximately 642,100 metric tons, down about 2,900 tons from the previous reporting period.

Although the reduction is relatively modest, it signals that market supplies continue to be gradually absorbed. Meanwhile, warehouse receipts on the Shanghai Futures Exchange (SHFE) have also declined, easing visible inventory pressure and limiting downside risks.

For the industry, lower inventories help maintain price support even as downstream demand remains relatively subdued.

Demand Remains the Main Constraint

Demand continues to be the key factor limiting stronger price gains.

The global tire industry remains in its seasonal off-peak period. Tire manufacturers in China continue operating at utilization rates above 60%, but finished tire inventories remain relatively high, prompting producers to purchase raw materials primarily on an as-needed basis rather than aggressively rebuilding inventories.

Consequently, demand has yet to recover sufficiently to support a sustained upward trend in rubber prices.

Nevertheless, market participants are becoming increasingly optimistic about September, when the traditional peak season for tire production and automotive demand in China typically begins. Seasonal restocking by manufacturers could provide additional support for natural rubber prices in the coming months.

Higher Crude Oil Prices Provide Additional Support

External factors have also contributed to the market's recovery, particularly stronger crude oil prices.

On Wednesday, Brent crude remained above US$91 per barrel, hovering near its highest level in almost three weeks. Oil prices have been supported by geopolitical risk premiums stemming from continued uncertainty surrounding shipping through the Strait of Hormuz, one of the world's most critical energy transit routes. In addition, disruptions to Russian crude exports from Black Sea ports have further tightened global oil supplies.

Higher crude oil prices increase production costs for synthetic rubber, a petroleum-based product. This improves the relative competitiveness of natural rubber and indirectly strengthens market sentiment.

Global Factors Continue to Influence the Market

Beyond energy markets, investors are also closely monitoring geopolitical developments in the Middle East and the outlook for U.S. monetary policy.

Persistent geopolitical uncertainty continues to support commodity markets through elevated risk premiums. At the same time, investors remain focused on signals from the U.S. Federal Reserve regarding future interest rate decisions, which could influence the U.S. dollar and investment flows into commodity markets.

Should geopolitical tensions escalate further, elevated energy prices could continue supporting natural rubber. Conversely, easing tensions and improving energy supplies could reduce some of the current risk premium.

Year-to-Date Trend Remains Positive

The SICOM TSR20 benchmark has maintained an overall upward trend throughout 2026 despite periods of volatility.

Prices began the year at approximately 181.7 US cents per kilogram in early January before climbing to around 234.5 US cents per kilogram in early June. After correcting in late June and consolidating throughout July, prices resumed their upward momentum in August, reaching approximately 228.2 US cents per kilogram on August 19, suggesting that bullish sentiment has gradually returned to the market.

Outlook

From a fundamental perspective, the short-term outlook for natural rubber remains constructive.

Declining inventories, elevated raw material costs, weather-related production constraints, and firm crude oil prices continue to provide underlying support. However, with downstream tire demand yet to fully recover, the upside potential is likely to remain limited.

Technical Analysis Disclaimer: The following technical outlook reflects market observations only and should not be considered investment advice.

From a technical perspective, SHFE rubber futures have successfully rebounded above the 18,300 yuan per ton level, opening the possibility of testing the 18,450–18,600 yuan per ton range if buying momentum continues. However, failure to maintain current levels could see prices consolidate again, with initial support expected around 18,100–18,200 yuan per ton.

Overall, the most likely near-term scenario is a bullish but range-bound rebound, with further price direction expected to depend largely on weather developments across Southeast Asia, movements in crude oil prices, and the pace of demand recovery ahead of the traditional peak tire manufacturing season in September.
