Soaring coffee prices force roasters to add lower-cost beans to blends

High-quality arabica and cheaper robusta beans have both surged in recent months

Global coffee prices have soared to record highs as adverse weather conditions disrupt crops, driving up costs for consumers and pushing roasters to add lower-cost beans to their blends.

Prices for both robusta beans, used in instant coffee, and the higher-quality arabica variety have surged in recent months. London robusta futures, the global benchmark, reached a record $4,971 per tonne this week, while arabica futures traded in New York climbed to $2.49 per pound, close to their highest in decades.

“Prices may not have reached their peak,” said Steve Butler, co-founder of ChAI, a commodity price forecasting firm that uses artificial intelligence. He added that the rally has attracted speculators, who are likely to continue increasing their bets that prices will keep rising.
