Rubber futures continue gains as monsoon season hits producing states
Stable crude oil prices provided additional support for pricing
Tokyo – Natural rubber futures have remained firm, driven by a mix of fresh speculative buying and short covering, according to Japan Exchange Group (JPX).
Prices strengthened over the week ended 18 July, as several producing countries experienced heavy rainfall.
Tropical Storm Wipha impacted Thailand, Vietnam, the eastern Philippines, and southern China, with the Thai Meteorological Department forecasting continued heavy rain from 19 to 24 July.
In Osaka, Japan, OSE's December-2025 contract closed up 3.7% week-on-week, while Shangahi’s SHFE and INE rubber closed up 3.2% and 2.6%, respectively.
In Singapore, SICOM's October-2025 contract closed 2.1% higher compared to the week before, JPX reported.
Rubber prices were also supported by stable crude oil prices and by China's strong total vehicle sales in June, which increased 8.1% to 2,904,482 units compared to May.
