Cooking oil prices are up 60%. The spike in the price of cooking oils is expected to remain high over the next few months, and could possibly extend until the end of the year. The crisis, which has been on-going for over a year, has been largely due to a global shortage in oil producing crops. The demands for oil are high, and currently standing, South Africa does not produce enough vegetable oil to be able to meet local demand. As a result, it has pushed the industry to source oils from Europe; having our domestic prices being influenced by international oil prices.
