In June, coffee and rubber futures in London and Osaka saw significant increases due to rising temperatures in Southeast Asia, particularly in Vietnam, Thailand, and the Philippines. The region experienced its hottest weather since April, with temperatures reaching up to 48°C, leading to a drought in Vietnam that has adversely affected the robusta coffee harvest. This drought, coupled with last year's low crop, has led to a tight supply-demand balance, causing robusta coffee futures to hit an all-time high of $4,394 per ton. Arabica coffee futures also saw a rise of 20.6%. The hot weather has also negatively impacted the price of natural rubber, a key export for Thailand and Indonesia.
