The Vietnam Commodity Exchange reported a mixed market on December 18, with the industrial raw material group leading the growth, driven by a near 7% surge in cocoa prices, reaching a new high. This increase is due to adverse weather conditions and supply shortages in West Africa, especially Ivory Coast, which is the largest cocoa supplier. The energy group also saw prices rising, with crude oil prices showing mixed reactions to the Federal Reserve's interest rate decision and US crude oil inventory data. Kazakhstan's decision to maintain its production levels also supported oil prices. Conversely, coffee prices had divergent movements, with Arabica coffee prices increasing while Robusta coffee prices decreased, largely due to rainfall concerns in Brazil.
