OSE rubber contracts close lower while Shanghai, SICOM post week-on-week gains
Tokyo – Natural rubber futures were mixed in the week ended 2 Oct, while remaining broadly supported following recent rallies.
Far East markets ended the week with fresh buying interest and some position adjustments ahead of China's long national day holiday, reported Japan Exchange Group (JPX).
OSE's February-2027 contract closed 0.4% down week-on-week amid “moderate trading.”
Despite the decline, JPX said prices remained “at another historic multi-year high,” with weekly trading volume increasing.
Market sentiment, it added, “remains bullish, with the uptrend firmly intact.”
In Shanghai, meanwhile, SHFE and INE rubber contracts ended the shortened trading week 1.5% and 1.0% higher respectively.
In Singapore, SICOM's active December-2026 contract closed up 2.3% week-on-week, recording its “highest close this year and a multi-year high” amid moderate trading activity.
JPX warned that SICOM rubber futures prices “could become volatile” as market liquidity declines during the closure of Chinese markets this week.
Overall, JPX said, supply disruptions caused by El Nino-related drought and flooding in Thailand had prompted market participants to add new long positions.
“Persistent high crude oil prices,” driven by rising Middle East tensions, along with ANRPC's recent downward revision to global rubber supply growth (ERJ report), also continued to support rubber prices.
