Rubber futures have surged to over 185 US cents per kilogram, marking their highest point since April 2025. This rise is driven by worries about diminishing raw material supplies in major rubber-producing nations due to adverse weather conditions. Thailand's meteorological agency has issued a warning about potential heavy and isolated thunderstorms between January 6th and 9th in the southern regions, which are crucial for rubber production. Additionally, the increase in oil prices is making synthetic alternatives less appealing, further pushing prices upward.
