Emergency Pod: Nick Kumleben of Greenmantle, the geopolitical risk consultancy headed by Niall Ferguson, joins us to discuss the events in Venezuela, the 'Donroe' Doctrine and what it means for commodities. Is Venezuela an oil story or something else? Is the Donroe Doctrine a structured, intelligible set of principles or just a catchy phrase coined by a New York tabloid ? Intelligible or not, what does it mean for adversaries, allies (Denmark and Greenland?) and the rest of Latin America. Commodities once again sit at the heart of global power politics and it's through that lens we investigate. And what in turn does it mean for commodity markets themselves... can they withstand such unpredictability and government interventions.
