In March 2026, Indonesia exported 108,000 tons of natural rubber, representing a 24% year-on-year decline.

As a key global exporter of natural rubber, Indonesia saw its export volume plummet significantly by 24% year-on-year in March, reaching 108,000 tons. This has reinforced expectations of tightening supply, providing substantial support to prices. On May 6, 2026, the benchmark natural rubber futures contract (Contract 2609) on the Shanghai Futures Exchange closed at 17,770 RMB/ton—an increase of 310 RMB/ton from the previous trading day—while open interest rose by 10,410 lots. With ample momentum driving futures prices upward, market fundamentals remain bullish for both spot and futures prices of natural rubber.

Polybutadiene rubber (BR) and natural rubber are substitutable commodities; consequently, the tightening supply and rising prices of natural rubber are expected to stimulate increased demand for polybutadiene rubber, thereby providing positive support to its pricing. On May 6, 2026, the benchmark butadiene rubber futures contract (Contract 2606) on the Shanghai Futures Exchange closed at 16,430 RMB/ton—up 80 RMB/ton from the previous trading day—with open interest increasing by 3,397 lots, indicating a strengthening trend in futures prices.

Styrene-butadiene rubber (SBR) also serves as a substitute for natural rubber; thus, the contraction in natural rubber supply and its upward price trajectory are expected to trigger a marginal increase in demand for styrene-butadiene rubber, offering slight positive support to its spot market prices.
