U.S. Wheat and Corn futures rose above their daily trading limits Thursday. Soybeans climbed the highest level since 2012. This was due to Russian forces firing missiles at Ukraine and landing troops along its South Coast, escalating concerns about global supply.

For the third consecutive day wheat rose, reaching its highest point in nine years. Meanwhile, corn reached an eighth-month record.

A few minutes after Russian President Vladimir Putin made a live televised address to state TV, you could hear explosions in the quiet pre-dawn of Kyiv.

Putin approved a military operation to take place in Ukraine. It was thought to signal the start of war across Europe, as Russia has demanded an end to NATO’s eastward expansion.

“Higher tensions surrounding Russia-Ukraine, and a fair bit of uncertainty over Russian supplies in the coming months has prompted traders have urged their grain to be kept at home instead of shipping it abroad,” ING commodity strategists wrote in a note.

Russia and Ukraine are responsible for approximately 29% global wheat exports. 19% world corn supplies and 80% world sunflower oil exports. Traders were afraid that any military involvement could have an impact on crop movement. This would trigger an immigrant scramble to get supplies from Russia.

The ING strategists stated that Russia-Ukraine tensions exacerbated global supply risk,” citing still-soft European Union wheat exports.
