Andy Hall's commodity career spans over 30 years and includes stints at BP Plc, legendary merchant house Phibro Energy Inc. and Citigroup Inc., where he pocketed $100 million trading oil during the financial crisis. Plus he ran his own hedge fund, Astenbeck Capital Management until it closed in 2017 after suffering heavy losses. The oil trader nicknamed “God” for his lucrative calls on crude, talks with Bloomberg's Alix Steel and Kevin O'Brien, the chief business officer at Orbital Insight, about oil prices and supply, his past fund and Orbital's ability to bring transparency to inventory data.
