CoinDesk news. Against the backdrop of the world agricultural products supply-and-demand outlook report being widely seen as having a neutral impact on the market, traders have shifted their focus back to the latest developments in the Russia-Ukraine war. Rumors that Russia is closing a key grain corridor are traders’ top concern. In a report, StoneX analyst Arlan Suderman said: “The main situation remains that, with the Kerch Strait closed, there has been some risk premium in the wheat market before the weekend arrives.” Earlier, Ukraine escalated strikes on Russian energy facilities, followed by concerns that key export infrastructure could be shut down. Traders are also worried about the risk that Russia’s retaliation could disrupt Ukraine’s wheat supply. Wheat futures rose 3.4%.
