Trading activity in Vietnam's coffee market is slow due to the absence of beans from the 2024/25 harvest, while premiums in Indonesia have risen due to global trends. Vietnamese farmers are selling beans in Dak Lak province at a lower price compared to last week, amidst volatile London prices and a yield decrease of up to 50% due to a heat wave. Meanwhile, Sumatra robusta coffee beans in Indonesia are being offered at a higher premium to adjust to London prices, indicating a significant change in the market.
