European wheat prices hit record high after Ukraine invasion

The price of wheat smashed its previous record high in European trading on Thursday as Russia invaded Ukraine, putting a question mark on the future of exports from two of the world's biggest producers of the key commodity.

Wheat soared to 344 euros ($384) a tonne, far above its previous record of 313.5 euros recorded late last year, said Edward de Saint-Denis of the brokerage firm Plantureux & Associates.

It later fell back to around 320 euros a tonne. The price of corn meanwhile shot up to 304 euros a tonne.

Agricultural commodities are usually much less volatile than stocks or oil, but have recently seen spectacular spikes and drops provoked by Russia's looming invasion of Ukraine.

The stakes are especially high for wheat, with Russia being the world's top exporter and Ukraine the fourth, according to estimates by the US Department of Agriculture (USDA).

The consequences for agricultural markets of Russia's invasion of Ukraine on Thursday, which provoked threats of broad sanctions against Moscow from the West, are still difficult to predict.

"It is totally unprecedented," said Sebastien Poncelet, an analyst with the French consultancy Agritel. "When we see that there are explosions in Odessa, which is the main Ukrainian port, we must assume there will not be much grain loaded there today," he said.

When Russia annexed the Crimea peninsula in 2014, then backed pro-Moscow separatists in Ukraine's east, prices rose by 15-20 per cent, before falling back after four to five months.
