The war in Iran is already built to break things. It is grinding through munitions at nearly a billion dollars a day, rerouting ships around two continents, and quietly starving the fertilizer arteries that make modern harvests possible—all as Washington places yet another unvoted, multi-billion‑dollar bet on the idea that the system can take one more hit. The question beneath all of this is brutally simple: how many more of these bets can a fraying, fossil‑fueled civilization place before it finally hits a limit it cannot bluff or bomb its way past?

Eight days into the US–Israeli campaign, Hormuz has become less a shipping lane than a test of how much risk a fossil‑fueled civilization can absorb. Iran’s Revolutionary Guard claims “complete control” over the strait and has vowed to set on fire any vessel that dares to cross. Tanker traffic has collapsed, maritime insurers have doubled or withdrawn war coverage, and the waterway that once carried roughly a fifth of the world’s oil and gas flows is effectively closed. Saudi Arabia’s Ras Tanura refinery—the beating heart of its export system—has been shut down twice by Iranian drones. Qatar declared force majeure—legal shorthand for saying an unforeseen, uncontrollable event made it impossible to deliver on its export contracts. Analysts now estimate that roughly a fifth of the planet’s crude and gas supply is suspended, either because fields and refineries have had to shut or because there is simply nowhere safe to send the barrels.

Energy prices have reacted immediately. Global oil benchmarks have surged by more than 25 percent since the first strikes, pushing Brent into the low 80s and driving up gasoline and diesel prices from Tokyo to Toledo. European gas prices spiked by more than 50 percent in a single day on news of Ras Laffan’s closure. But these moves, dramatic as they feel to consumers, are only the opening chords. On their own, oil in the 80s and a few weeks of high LNG prices are survivable. What threatens to become truly dangerous is the possibility that the war locks the system into structurally higher prices and chronic uncertainty, at the same time that it quietly sabotages the inputs that grow food.

To understand how far this can go, it helps to mark the thresholds. History suggests that oil at 90–110 dollars for a few months can slow growth and aggravate inflation without collapsing the architecture; the 1970s crises only arrived when prices quadrupled and stayed high for years. Today, analysts at Goldman Sachs reckon that each sustained 10‑dollar jump in oil adds roughly 0.3 percentage points to US inflation and knocks 0.1 points off growth. That is annoying, not apocalyptic. But the war is already flirting with the next band. Hormuz’s near‑shutdown forces Saudi Arabia, Kuwait, Iraq, and the UAE to curb production as storage fills and tankers stay in port. Qatar’s loss deprives Europe and Asia of a key gas supplier at precisely the wrong time. Oilfields that are shut in cannot simply be flipped back on; depending on age and geology, it can take weeks or months to restore previous flows once the pipelines and loading arms are safe again.

If this continues—if Hormuz remains unsafe, if Ras Tanura and Ras Laffan and other Gulf facilities limp along or stay dark—the world drifts toward a scenario where Brent hovers in the 120–150 dollar range, not for days but for seasons. At that point, energy costs stop being a bad quarter and start becoming the air a recession breathes. High‑income countries can tap strategic reserves and lean on their own production. Import‑dependent states in Asia, Africa, and Latin America cannot. They face soaring import bills, weaker currencies, and the kind of fiscal squeeze that makes debt crises and IMF “rescues” feel inevitable.​

Yet oil is only the most visible part of the story. The deeper fuse runs through fertilizer. The same Gulf that exports crude and LNG also exports the nitrogen and sulfur that underpin modern yields. According to recent trade data reported in The Economic Times and Bloomberg, the Strait of Hormuz handles roughly a third of global fertilizer trade, including about 35 percent of global urea and 45 percent of sulfur exports. Iran is the world’s third‑largest producer of ammonia, and Qatar and its neighbors ship vast quantities of urea, ammonia, and sulfur‑based products worldwide. Those flows are now snarled. Granular urea prices in the Middle East have surged; European ammonia futures have climbed into the 700‑dollar‑per‑tonne range; Indian urea producers are already cutting output as LNG cargoes from Qatar disappear. Russia, despite being the single largest fertilizer exporter, cannot fully backstop these losses because of production bottlenecks, its own export limits, and domestic obligations.​

The timing could hardly be worse. Northern Hemisphere farmers are heading into spring application season now. Fertilizer is not like oil; you cannot simply “catch up” by applying it later. If supplies are tight and prices elevated during planting and early growth, farmers either pay through the nose, cut back on application, switch to lower‑input crops, or leave land fallow. The full effect only shows up months later, when harvests are weighed and markets discover that there is less wheat, corn, soy, and rice than planned. Analysts quoted in the Financial Times and Reuters warn that if this disruption runs through the current planting window, the world could see a food price shock equal to or worse than the one triggered by Russia’s invasion of Ukraine in 2022.

This is the shape of genuine systemic risk: not a single commodity going vertical, but multiple interlocked flows—oil, gas, fertilizer, container shipping—staying kinked for long enough that the fabric starts to tear. Hormuz’s closure forces producers to shut in fields and storage; Iranian drones and missiles hit refineries and LNG trains; ships avoid the Red Sea as Houthis again menace Bab el‑Mandeb, driving container lines like Maersk back around the Cape of Good Hope and adding weeks and cost to global trade. Qatar’s energy minister, not known for alarmism, has already warned that if the war continues “for a few weeks,” it will “bring down the economies of the world,” by which he means push them into a combination of chronic inflation, weak growth, and cascading shortages.

Even the financial plumbing that has long underpinned the American order is starting to flinch. The wealthiest Gulf monarchies—Saudi Arabia, the UAE, Qatar, and Kuwait—are now reviewing tens of billions of dollars in planned and existing investments in the United States and other Western markets as war damage, lost exports, and higher defense spending squeeze their budgets. Sovereign wealth funds built as “rainy day” vehicles are being tapped to plug fiscal holes at home, and officials are quietly signaling that future capital will be redirected toward domestic projects and non‑Western partners rather than automatically recycled into Wall Street. For an empire that has long relied on Gulf petrodollars to finance its deficits and asset bubbles, a war that simultaneously threatens those states’ export arteries and erodes their appetite for US exposure is not just a regional miscalculation; it is another way of sawing at the floorboards beneath its own financial house.​

In Washington, this unauthorized adventure is burning money at a rate that would make even a Pentagon comptroller blink. Because Congress never debated, let alone passed, a new authorization for war with Iran, the administration is operating entirely on the fumes of old Authorizations for Use of Military Force and a creative reading of the president’s Article II powers. There has been no declaration of war and no specific statutory authorization for bombing a sovereign state on this scale; constitutional scholars from the ACLU to former government lawyers have been blunt in calling it illegal. Yet every day, the United States pours roughly 900 million to 1 billion dollars into Operation Epic Fury. Estimates from the Center for Strategic and International Studies, echoed by ABC News and CNN, suggest the first 100 hours cost about 3.7 billion dollars—some 891.4 million per day—in munitions and operations alone. A congressional source has relayed a preliminary Pentagon estimate of roughly 1 billion dollars a day going forward, with Defense Secretary Pete Hegseth hinting the tempo will increase as more bomber missions and missile defenses come online.

Almost none of this is budgeted. CSIS’s breakdown notes that only a sliver of the first week’s spending fit inside existing appropriations; the rest will require supplemental requests to replace thousands of precision munitions—Tomahawks, Patriots, THAAD interceptors—and cover the burn rate of advanced aircraft and naval groups. Pentagon planners are reportedly working on a 50 billion dollar supplemental just to refill missile stocks, and that assumes the war does not expand or drag on beyond the eight‑week horizon some officials are whispering to reporters. That is money Congress has not authorized for this purpose, spent on a war Congress has not formally approved, at a time when lawmakers already profess alarm at deficits and interest costs. It is hard to think of a clearer illustration of what “managed collapse” looks like in fiscal form: unlegislated commitments made on the assumption that someone, somewhere, will be forced to pick up the bill.

The bill is not just monetary. The same unauthorized war powers logic that allows a president to launch a massive air campaign without a vote also normalizes the idea that fundamental decisions about national and planetary risk can be made by a small executive circle and a handful of think‑tank lawyers. The Office of Legal Counsel has, over decades, evolved a test under which presidents are permitted to wage significant military operations without Congress so long as they serve “sufficiently important national interests” and are not expected to rise to the level of “war” in the constitutional sense. In practice, that amounts to: if the president says it is important and thinks he can keep casualties manageable, he can do it. Iran blows that premise apart. The risks of escalation, regional spillover, and major American losses are obvious. That they were ignored tells you a great deal about how degraded the checks on imperial power have become.​

All of this reads like a close‑up of the operating system I have been describing. A war sold as decisive and contained is rapidly turning into an open‑ended drain: on munitions stockpiles, on fiscal space, on shipping routes, on the fertilizers and fuels that keep shelves stocked. Oil in the low 80s is a warning shot; oil sustained north of 120 dollars for six to twelve months, with LNG tight and fertilizer scarce, would be something closer to a slow‑motion heart attack. It would not “destroy” the global economy in the sense of flicking a switch to off. But it would likely drive multiple major economies into synchronized recession, tip heavily indebted, energy‑importing states into default and IMF tutelage, inflate food prices in ways that hit the poor hardest and stoke unrest, and justify further securitization—more border walls, more riot gear, more surveillance—in the name of stability.

And all of it would be framed as unfortunate but necessary side effects of a war that, constitutionally speaking, was never actually authorized. The president spends a billion dollars a day on an illegal war; the war sends oil, gas, and fertilizer prices into the red; the resulting inflation and shortages are used to argue that there is no money for climate transition, no room for expanded social protections, no alternative to tightening belts and tightening controls. That is managed collapse in miniature: the system does not fall by accident, it is steered down a staircase of “tough choices” that somehow always protect the same people.

There is, of course, nothing inevitable about this trajectory. Congress could still claw back its war powers, refuse supplemental requests, and force a halt. Diplomats could, in theory, broker a ceasefire that reopens Hormuz before planting seasons are fully lost. The US could decide that it is not, in fact, worth risking stagflation and food crises in exchange for another symbolic display of air supremacy. But none of those outcomes are consistent with how the American empire has behaved in recent decades. It is far more consistent with its habits to keep bombing, keep spending, keep insisting that victory is around the corner, while supply chains fray and households watch prices climb.

The war in Iran is not yet the event that shuts down the global economy for good. But it is a real‑time demonstration of how little slack remains in the system, and how casually that slack can be burned by leaders unbound by law and insulated from consequence. Oil does not have to stay at 150 dollars forever to break things; fertilizer does not have to vanish completely to starve people. It is enough that prices and shortages cross certain thresholds and stay there long enough to erode what remains of social and ecological resilience.

In that sense, the daily billion dollars Washington is quietly spending on unauthorized war is not just a line item; it is a wager that the machine can take yet another shock without coming apart. Each new strike, each new supplemental, assumes there will always be enough slack in the system—enough credit, enough patience, enough ecological cushion—to absorb the blow. At some point, a civilization this frayed and this fossil‑fueled will place one bet too many—and realize, with perfect clarity and no way back, that the system it kept gambling on has already come apart.
