Over the weekend, at the age of 92, one of the giants of American economic policy and former head of the US central bank Paul Volcker, died at his home in New York. He was perhaps best known for his dramatic hiking of interest rates in the early eighties to fight inflation. We explore his enduring legacy. Meanwhile, shares in Tullow Oil fell as much as 70% after the company announced a boardroom shake-up, scrapped its dividend and cut its production forecasts. Chief executive Paul McDade and exploration director Angus McCoss are stepping down immediately. We talk to Eklavya Gupte, senior editor of Europe and Africa News S&P Global Platts. Robin Harding, Tokyo Bureau Chief or Financial Times and Alexis Goldstein, an activist and financial reform advocate in Washington join the discussion. (Picture Credit: Getty Images)
