Almost three months ago, the president started the war on Iran. Iran responded by blocking the Strait of Hormuz, and shipping from the Persian Gulf dropped 95 percent, virtually eliminating a fifth of the global oil supply. Pipelines and overland trucking have allowed some oil to move, but the shortage is still significant. Published crude oil prices have already jumped from $65/barrel to $104/barrel, and we can all see the impact at the pump.
But this is only part of the story. The prices quoted are paper prices, distinct from "dated" prices for delivery of physical oil. Before the war, dated prices were usually close to paper prices. But the abrupt closure prioritized having the physical oil over future deliveries, so dated oil jumped an additional $30-$50/barrel. In recent days this physical oil premium has declined some, due to buyer reliance on stored inventory and hope the conflict will resolve quickly. But that hope is fading as the stalemate grinds on, and all storage is finite.
What we have experienced so far is war induced price inflation, with adequate product still available. The chapter beginning now is an actual reduction in supply. But the reduction will not be experienced evenly and prices may spike even higher. Rural areas will be hit harder, as their economic clout is smaller.
Here in California, a third of our oil in produced in state and the rest is imported by sea, because there are no oil pipelines from the east. One third of our imported oil comes from the Persian Gulf. But a change is about to happen. The last tanker of prewar Persian Gulf oil unloaded in Long Beach on the third of May, leaving a 20 percent shortfall going forward, although there is some oil in storage.
Even if the Strait opened tomorrow, it would take time to get much of that oil delivered. Oil infrastructure in the war zone has been damaged. Sources have reduced production, requiring time to get back to former levels. It is estimated that it will take as much as a year to return to prewar levels of production and prices, even with a quick resolution and no further damage.
There will be problematic disparities within the economy, because not all fossil fuels are equal, with diesel being the most important. In the U.S., most of our domestic oil is from fracking, which is too light to be refined into diesel without adding heavy crude imported from elsewhere. This puts us in competition with the rest of the world, which also needs heavy crude.
Most developed economies are diesel powered, especially the food systems, which includes basic agricultural production, processing, bulk transportation, and retail distribution. A diesel shortage anywhere in the food system will eventually express as bare spots on grocery store shelves. We are not approaching a food crisis. It has already begun.
Nitrogen fertilizer is mostly produced from natural gas, which the Hormuz closure has disrupted, so prices are surging. Airlines everywhere are facing higher jet fuel prices as supplies plummet. The Spirit Airlines bankruptcy is just the first. Liquefied natural gas is essential for manufacturing, chemical production, and heating systems. Naphtha supplies the petrochemical raw material for plastics, solvents, and industrial chemicals. Persian Gulf exports, one fifth of the global total, have ceased. All supply chains are being affected, as the oil crisis becomes an "everything crisis".
Asia and the Pacific region were hit first, being closer, and more dependent of Persian Gulf exports. Europe will exhaust their stored supplies this month. America will be hit by July, in part because the U.S. has expanded exports to the rest of the world, acting as if everything is under control, even though we can't even supply our own needs.
There are no simple, or quick, solutions. The president, too distracted by his ballroom, won't save us even though he created this entire problem when he unilaterally welched on the international Iranian nuclear deal eight years ago. Republicans won't save us, because they are subservient to the president. However, they may be overwhelmed by voter outrage.
This is not an extinction event, but it will be a long-lasting emergency. We have to reduce fossil fuel consumption immediately, in order control prices and preserve societal essentials. Life as we have known it will change. This is a community-level challenge, not an individual one. The people who survive systemic disruption are the ones who organize, share, and look out for each other.
