The International Energy Agency published on Friday a set of demand reduction recommendations that read less like the output of a multilateral economic institution and more like the wartime rationing directives that democratic governments issued to their populations in the 1940s. Work from home where possible. Lower national speed limits. Shift from private automobiles to public transit. Implement alternate-day vehicle access in urban centers. Prioritize liquefied petroleum gas for cooking and heating rather than transportation. Reduce discretionary air travel. The language is measured — the IEA does not traffic in panic — but the message is unambiguous: the supply-side measures that the world’s governments have deployed in response to the effective closure of the Strait of Hormuz are necessary but insufficient, and the gap between what those measures can deliver and what the global economy requires must be closed by the one variable that governments can influence most rapidly, which is the behavior of the people who consume the oil.
The arithmetic that drives the IEA’s prescription is brutal in its simplicity. Road transport accounts for approximately forty-five percent of global oil demand — the single largest category of petroleum consumption on earth. Every reduction in road transport demand delivers a proportionally larger impact on total oil consumption than equivalent reductions in any other sector. A global reduction in highway speed limits to one hundred kilometers per hour, the agency estimates, would save approximately four hundred and thirty thousand barrels per day. A shift of one in ten car trips to public transit would save a further two hundred and seventy thousand barrels. The adoption of work-from-home policies by a meaningful fraction of the global workforce that is capable of remote work would reduce commuting demand by an amount the agency estimates at approximately five hundred thousand barrels per day. These are not trivial figures, but neither are they sufficient: combined, they offset approximately one million barrels per day against a shortfall that the agency’s own March report quantifies at fifteen million.
The strategic petroleum reserve releases that IEA member nations have agreed upon — four hundred million barrels, drawn down at a pace of approximately two million barrels per day — represent the largest coordinated reserve deployment in the institution’s fifty-year history. The releases are designed to prevent physical shortages at refineries and to moderate the price increases that have already pushed Brent crude above one hundred and ten dollars per barrel. But reserves are, by definition, finite. At the current draw-down pace, the four hundred million barrel release will be exhausted in approximately two hundred days. If the Strait of Hormuz remains closed beyond that horizon, the world’s governments will face a choice between depleting their emergency stockpiles below the levels considered minimum for national security or accepting the physical shortages that the reserves were designed to prevent.
Avery Ash, the vice president for public affairs at Securing America’s Future Energy, articulated the predicament with a clarity that the institutional language of the IEA is designed to avoid. “The worst time to solve an energy crisis is when you are in an energy crisis,” he stated in an interview with this publication. “Every measure we are discussing — demand reduction, reserve releases, alternative supply routes — these are things that should have been prepared for years ago. We are improvising solutions to a scenario that was foreseeable and foreseen, and the improvisation is costing us orders of magnitude more than the preparation would have.”
Bob McNally, the president of Rapidan Energy Group and a former energy advisor in the George W. Bush White House, placed the strategic reserve releases in the context of their market impact. “Reserves slow the ascent by pennies,” he stated. “They do not reverse it. They do not address the underlying supply deficit. They buy time, and the question — the only question that matters — is what you do with the time they buy.” McNally argued that the time purchased by reserve releases is being consumed by political deliberation rather than strategic action, and that every week the Strait remains closed narrows the range of options available to policymakers.
Dan Pickering, the founder of Pickering Energy Partners, delivered the assessment that has become the crisis’s defining calculation. “Fifteen million barrels a day is not easy to offset anywhere,” he stated. “That is the total production of the United States of America. You are asking the world to find a replacement for the equivalent of shutting down every oil well in the country. That replacement does not exist. The only thing that replaces fifteen million barrels a day through the Strait of Hormuz is fifteen million barrels a day through the Strait of Hormuz.”
The IEA’s recommendations will be implemented unevenly, incompletely, and with the friction that characterizes democratic governance confronting collective-action problems under conditions of urgency. Some nations will lower speed limits; others will conclude that the political cost exceeds the energy benefit. Some employers will embrace remote work; others will determine that productivity concerns outweigh energy conservation. The alternate-day driving restrictions that the agency recommends have precedent — Athens, Paris, and Mexico City have all implemented versions during pollution or energy emergencies — but their effectiveness depends on enforcement capacity and public compliance, both of which vary enormously across the hundred-plus nations that the IEA’s guidance nominally addresses.
The uncomfortable truth that the IEA’s report documents without quite stating is that the global economy’s dependence on a single maritime chokepoint has created a vulnerability so profound that no combination of supply measures, demand reductions, and strategic reserve deployments can fully compensate for its exploitation. The Strait of Hormuz is not merely a shipping lane; it is the aorta of the industrial world, and the industrial world has known this for decades and has done nothing to develop the redundancy that prudent infrastructure management requires. The IEA’s prescriptions are the medicine available for the disease at hand. The cure remains what it has always been: an open strait and the political settlement necessary to keep it open.
