Cocoa futures experienced a significant rebound after a major weekly loss, with prices in London and New York increasing by approximately 4%. This rise is attributed to concerns over global supply, especially with the cocoa crop in West Africa, the largest production region. The market's volatility is further exacerbated by record-low exchange-certified inventories, leading to the commodity's high value in 2024. Additionally, the grains market saw an increase in corn futures due to worries about Argentine crops affected by dry weather. The market is also influenced by strong demand and climate risk, resulting in pressure on prices and maintaining high market volatility.
