What Variables Drive Natural Rubber Prices?
Six Categories of Variables
Supply: rainfall, drought, typhoons, disease, tapping suspension periods, tree age, tapper shortages, and farmers' willingness to tap in major producing countries. Demand: tire plant operating rates, passenger and commercial vehicles, replacement tires, mining, infrastructure, export orders, and manufacturing activity.
Substitution and Cost: crude oil, butadiene, and synthetic rubber prices alter the compounding economics between NR and SR. Trade: exchange rates, ocean freight, tariffs, trade remedies, cross-border customs clearance, and rules of origin. Inventory and Capital: port and exchange inventories, factory safety stocks, trade finance, and interest rates. Sustainability: deforestation risks, plot traceability, supply chain due diligence, and customer certifications.
Pricing Benchmarks
SGX SICOM TSR20 futures are used to track international bulk standard rubber trends and are commonly adopted in formula pricing and risk management; Malaysian Rubber Exchange spot reference prices help interpret Southeast Asian physical spot differentials and grade premiums/discounts. The SHFE RU contract deliverables are domestic whole-latex rubber and imported RSS3; the INE NR contract corresponds to 20-grade rubber, with a trading unit of 10 tonnes per lot. The two contracts do not represent the same pricing benchmark.
Ex-factory spot quotations ultimately depend on the factory, batch, volume, payment terms, Incoterms, and shipping schedule. Newcomers should avoid drawing a price conclusion from a single variable: heavy rains in producing regions may push up raw material costs, but if tire manufacturers actively de-stock, spot prices can still face downward pressure.
