After recent failures to bring the Kremlin to the negotiating table to end the war in Ukraine, Trump has adopted a new approach to Putin, taking the significant step of sanctioning Russia’s two biggest oil producers, Rosneft and Lukoil, while also demanding that China and India stop buying Russian oil. Will this step finally persuade Putin to negotiate an end to his war? Why has it taken the United States so long to go after the two biggest cash cows in Putin’s war chest? Will these sanctions have any side effects for global markets?
