Olive oil reserves for the 2023/24 season are at a historically low level of 0.77 million tons due to high demand and low production. Spain, the largest producer of olive oil, experienced a significant reduction in output. The tight supply and increasing prices are also a result of the spread of the Xylella fastidiosa bacterium, which poses a threat to olive plantations in Spain and Greece, potentially leading to a further increase in the cost of olive oil for consumers.
