The sparsely detailed but highly ambitious set of reforms known as Vision 2030 was announced by Deputy Crown Prince Mohammed bin Salman on April 25. The imperatives are designed to reassure Saudi citizens that the kingdom has their best interests at heart, even as it seeks to lessen its deep dependence on oil. Yet the king's recent message — which announced the retirement of the internationally known Saudi oil minister as well as major changes to the kingdom's financial leadership — resonated more with an international audience, one coming to terms with the fact that the Saudis are serious about reform. A New Minister at the Oil Helm Markets have responded with uncertainty to the news that the country's oil ministry is undergoing major changes. Specifically, Khalid al-Falih, a career man at the state-owned energy giant Saudi Arabian Oil Co. (better known as Aramco), has replaced 21-year-veteran Ali al-Naimi.
