A US-Iran deal signals a post-conflict future, fundamentally reshaping the global energy landscape. The oil market faces significant shifts, with oil-importing economies prioritizing renewable energy for resilience. This will fragment oil trade, distancing it from the petrodollar system and altering global power dynamics away from fossil fuels. Manufacturing and agriculture will adapt to energy disruptions, favoring protected markets and localized supply chains. Long-term behavioral changes and disinvestments in traditional oil infrastructure are expected. While natural gas serves as a transition, synthetic hydrocarbons and plastics production will redefine oil's future, with rare earths gaining prominence.
