John welcomes The Economist's editor-in-chief, Zanny Minton Beddoes, to discuss the economic fallout from the war in Iran, her magazine’s midterm election special issue, and more. Zanny outlines the scale of the coming global oil supply shock due to the two-month closure of the Strait of Hormuz; why the U.S. stock market has remained buoyant regardless; whether Kevin Warsh will be an independent Fed chair or a toady to Donald Trump; and the prospects that Trump will succeed in interfering with the midterms.
