The recent volatility in the coffee market is expected to persist for several years, according to Giuseppe Lavazza, chairman of Italian roaster Luigi Lavazza SpA. Speaking in London, Lavazza highlighted the need for market stability before any significant reduction in coffee prices can occur, projecting that lower prices are unlikely to materialize within the next two years.

Lavazza explained that easing supply constraints will require at least two consecutive strong harvests and a substantial rebuilding of global coffee inventories. This outlook comes amid fluctuating Arabica futures in New York, which experienced the largest intraday jump in 26 years on Monday before giving back much of the gains in subsequent sessions. Prices remained volatile on Wednesday as the market balanced expectations of a record Brazilian crop against concerns over the impact of the El Niño weather phenomenon.

The premium Arabica variety, popular with specialty coffee chains such as Starbucks Corp., had seen some price relief following optimistic projections of a large Brazilian harvest. However, that optimism has been tempered by tightening inventories, delays in Brazil’s crop cycle, and renewed investor apprehension over weather-related disruptions.

El Niño, identified last month, has contributed to about a 30% surge in coffee prices since its announcement. This climatic event typically brings unseasonable temperature and precipitation shifts that can negatively affect crop yields, especially during Brazil’s flowering season when hotter and drier conditions can reduce Arabica output.

Roasters like Lavazza’s company are facing tighter profit margins as a result of these supply challenges. Lavazza emphasized that recovery will depend heavily on strong crops from major producers Brazil and Vietnam. “We need a couple of very strong crops from Brazil and Vietnam to rebuild stability,” he said, adding that while initial indications suggest the first crop is arriving, there remains uncertainty about whether it will meet earlier expectations.

Overall, the coffee market appears poised for continued instability, with producers, investors, and consumers all navigating the challenges posed by weather variability and supply chain pressures.
