Russia's brief blockage of a key shipping channel for Black Sea grain highlights the risk of disruption to an important source of global supply, reports Bloomberg.
Russia cut off access to the Kerch Strait between the Sea of Azov and the Black Sea after tensions with Urkraine flared over the weekend and has since reopened the passage.
Still, the conflict means some traders will likely reroute cargoes to avoid passing through the straight, according to the Urkainian Grain Association.
