Global wheat prices hit a new record high two days after India, the world's second-largest wheat producer, announced it was banning exports of the commodity.
Wheat prices surged to a new record high after India decided to ban exports of the commodity as a heatwave hit production.
The price jumped to 435 euros ($453) per tonne as the European market opened on Monday.
Global wheat prices have soared on supply fears since Russia's February attack on agricultural powerhouse Ukraine, which previously accounted for 12 percent of global exports.
The spike, exacerbated by fertiliser shortages and poor harvests, has fuelled inflation globally and raised fears of famine and social unrest in poorer countries.
India, the world's second-largest wheat producer, said on Saturday that it was banning exports after its hottest March on record.
New Delhi said factors including lower production and sharply higher global prices meant it was worried about the food security of its own 1.4 billion people.

However, exports could also take place if New Delhi approved requests from other governments "to meet their food security needs."

India, which possesses major buffer stocks, previously said it was ready to help fill some of the supply shortages caused by the Ukraine conflict.
The export ban drew sharp criticism from the Group of Seven industrialised nations, which said that such measures "would worsen the crisis" of rising commodity prices.
