Vegetable oil prices in Vietnam have seen significant increases, with retail prices doubling from 2020 and being adjusted three times already this year. The price hike is primarily due to the surge in production material costs, further exacerbated by Indonesia's ban on crude palm oil exports. This situation is causing concern for manufacturers and consumers alike, with other edible oils such as soybean, sunflower, and brown rice oil also seeing price increases. The rising costs are affecting purchasing power and have led to stock shortages in various countries, including India and Europe, where cooking oil supplies are becoming scanty and prices are escalating.
