YLE (Finland) published an article writing that when one country bans the export of food products, the others typically follow suit. This will create a panic-like atmosphere in which prices will only rise higher. As the crisis approaches, hoarding begins. How to prevent the uncontrolled rise in food prices and ensure that food is available around the world? Senior researcher Kalle Hirvonen replied that at least it is clear what should not be done. Exports of food products should not be restricted, as this will only exacerbate the situation. This was the case during the 2008 food price crisis. As large producer countries restricted their exports, prices rose even higher. World Bank researchers estimate that about 45 percent of the increase in rice prices and 30 percent of the increase in wheat prices at that time was due to barriers to trade, Hirvonen said. IFPRI has collected data on export restrictions (See tool, Food & Fertilizer Export Restrictions Tracker) and has found restrictions have already been applied almost as widely as during the 2008 price crisis. In early June, a total of 27 countries have imposed barriers to trade in food products. In 2008, that figure was 33. IFPRI researchers warn that in previous crises barriers to trade have been erected as a chain. When one country bans exports, the others follow suit, creating a panic-like atmosphere in which prices continue to shoot higher and higher.
