Vietnam's domestic coffee prices have experienced a significant drop of 16,000 - 19,800 VND/kg, due to pressure from the global market and profit-taking activities. This decrease is also influenced by a harvest season where farmers have not yet increased sales. Meanwhile, world Robusta coffee prices on the London floor have reached their lowest in over two weeks, dropping by 199 - 208 USD/ton. Arabica coffee prices on the New York floor also saw a slight decrease. This decline is attributed to various factors, including market sell-off and a decrease in export volumes.
