The last pre-war shipments of oil products from the Strait of Hormuz have arrived at their destinations as of early May, meaning the promise of an energy crisis as a result of the Iran war is fast approaching. Leading experts are now forecasting energy disruptions ranging from rationing to severe shortages in import-dependent economies, with roughly 11% of global oil supply already offline. This leaves us with the question: even if this war were to end today, what sort of system-wide effects are locked in given the current loss in production, and what will be required of us to cope with the fallout?

In this episode, Nate welcomes back petroleum geologist Art Berman to break down the timeline of the looming oil shortages stemming from the Strait of Hormuz crisis and just how severe they could become within a tightly coupled, complex global system. Art explains why, even if the war were to end today, the inherent lags in our industrial supply chains mean shortfalls are already baked into the coming months. The resulting rise in energy prices will reach far beyond the pump, rippling out into the cost of virtually everything and confronting much of the world with conditions not seen in over five decades. Ultimately, Art sees this as a forcing mechanism that could compress decades of needed adjustment into months. The outcome will rely less on policy than on whether societies can absorb the shock without breaking.

Amid all the speculation about oil prices in the wake of the Iranian conflict, what do these numbers actually mean in physical terms? If this conflict signals the beginning of a long-term decline in energy availability, are we already past the peak of the global material economy, with the financial layer not yet caught up to the physics? And if this conflict signals the beginning of a long-term decline in energy availability, what lessons from our deep past might help us find our way forward?
