Wheat prices are reaching a nine-year high worldwide due to adverse climate conditions and a poor harvest in key export countries like Russia, leading to an increase in the cost of bread and other wheat-based foods. The price rise is expected to continue, making food more expensive and potentially leading to higher inflation and more hunger. The situation is worsened by small harvests in other grain-producing countries and the fact that much wheat is stored in countries like China that seldom export. Russia, the largest wheat exporter, has started taxing exports to control domestic costs and secure supplies, further driving up prices.
