JPX: Prices likely to remain weak in coming weeks, with subdued sentiment to persist until after New Year
Tokyo – Natural rubber futures finished the first trading week of December lower across all major exchanges, pressured by renewed speculative selling and long liquidation.
Traders who had built long positions ahead of the year-end monsoon season and flooding in major producing regions “missed the expected rally,” said Japan Exchange Group (JPX) in an 8 Dec NR update.
Weaker rubber demand from Europe, the ongoing impact of US tariffs, and high inventory levels in China continued to cap gains, exerting pressure throughout recent sessions, JPX added.
In Osaka, OSE’s May-2026 delivery contract closed sharply lower, down 5.8% week-on-week after retreating from overbought levels.
In Shanghai, SHFE and INE rubber contracts declined 2.3% and 0.9% respectively, amid subdued volumes.
In Singapore, SICOM’s active March-2026 contract slipped 1.2% week-on-week amid fresh selling interest, remaining trapped in "a narrow range" throughout the week.
According to JPX, the “broadly flat forward curve” across exchanges suggests prices are likely to remain weak in the coming weeks, with sentiment expected to stay subdued until after the New Year.
In related news, heavy monsoon rains and flooding in southern Thailand affected roughly 600,000 hectares of rubber plantations and disrupted tapping, though the impact on prices has been limited so far.
