Commercial shipping has been temporarily halted by Russia in the Kerch Strait and Don-Azov Canal due to a substantial Ukrainian drone operation aimed at Russian maritime logistics and petroleum infrastructure. Ukrainian military sources claim to have targeted 18 Russian vessels, among which are 13 sanctioned oil tankers associated with Moscow’s covert fleet. This interruption impacts a shipping corridor responsible for approximately 25% of Russia's wheat exports, leading to a nearly 4% increase in Euronext wheat futures following the announcement. These events underscore the escalating effects of the conflict on local trade, energy systems, and international commodity markets.
