China’s Domestic Synthetic Rubber Production Rises 7.6% YoY in July, Weighing on Market Prices
China’s domestic synthetic rubber industry recorded a 7.6% year-on-year increase in production during July 2026, signaling a notable expansion in overall supply across key rubber categories. The higher output has strengthened market availability and created moderate downward pressure on both spot and futures prices, although the impact varies among individual product segments depending on demand and inventory levels.
The production growth reflects steady operating rates at domestic manufacturing facilities and improved capacity utilization, contributing to greater supply in the country’s synthetic rubber market. As a result, traders and downstream buyers have adopted a cautious stance amid expectations of continued supply-side pressure.
SBR faces moderate bearish sentiment
Styrene-butadiene rubber (SBR), one of the most widely used synthetic rubber grades in tire manufacturing and industrial applications, is experiencing moderate bearish pressure following the increase in domestic production. The broader rise in industry supply has improved spot market availability, limiting the potential for significant price gains in the near term. Futures prices have also softened as market participants anticipate adequate supply through the coming months.
NBR remains relatively resilient
Nitrile butadiene rubber (NBR), a specialized rubber used in automotive seals, hoses, gloves, and oil-resistant applications, has also seen a slight increase in supply. However, the pricing impact remains relatively limited compared to commodity rubber grades. Stable demand from industrial and automotive sectors has helped cushion the market, resulting in only a mildly bearish outlook despite the broader production expansion.
BR supply increase pressures prices
Cis-polybutadiene rubber (BR), another core synthetic rubber variety widely consumed in tire production, has been more directly affected by the July output growth. The higher production volumes have significantly expanded market supply, placing moderate downward pressure on both spot and futures prices. Increased availability has reduced buying urgency among downstream processors, contributing to weaker market sentiment.
Futures market reflects short-term weakness
The broader synthetic rubber market continues to exhibit a soft trading trend. Butadiene rubber futures have reflected the supply-driven weakness, with the benchmark 2610 contract closing at RMB 14,465 per tonne on August 20, down RMB 40 per tonne from the previous trading session. The decline indicates cautious market expectations as participants monitor inventory levels, downstream demand recovery, and feedstock cost movements.
While the July production increase has reinforced bearish sentiment in the short term, market analysts note that future price direction will largely depend on the pace of demand from the automotive and tire industries, export orders, and any adjustments in operating rates by domestic synthetic rubber producers.
