Consumers are expected to cut back on chocolate consumption as cocoa prices have surged due to a global shortage, prompting manufacturers like Nestle to raise prices. Cocoa futures have more than doubled this year, and while companies have hedged supplies at lower prices, they will eventually need to pass on the higher costs to consumers. Nestle's managing director, Mark Davies, foresees a decline in demand as prices rise. The supply crunch has already led some chocolatiers to increase prices or reduce bar sizes, and the industry may turn to more cocoa substitutes. Additionally, Nestle is expanding a program to support African cocoa farmers.
