Portugal does not have a legal requirement for a strategic reserve of food raw materials. The country has cereal reserves that last around 1.5 to 2 months. Cereal importers are discussing with silo owners to use them for longer periods to increase food security. The price of maize and wheat is increasing due to the invasion of Ukraine by Russia, which accounts for a significant portion of global wheat and corn exports. Chinese President Xi Jinping has highlighted food supply as a priority, and European producer associations have suggested importing cereals from the US, Brazil, and Argentina.
