"2027 Will Be a Year of Massive Shortages:
Oil, War and a Supply Chain With No Safety Net"
by Milan Adams
"Crude moved more than five percent in a single American session on Thursday, and the headline figure was not the most alarming part of it. Brent crossed $105 a barrel, West Texas Intermediate pushed toward $93, and diesel futures rose 4.5 percent in European trade with heating oil trailing behind. Ten-year Treasury yields touched a 24-year high of 5.35 percent before easing back, pulling the rest of the curve higher in their wake. Four markets, four jolts, one afternoon.
Two explanations were offered for the violence of that move, and both sit inside bodies of water that share a name. One is a hurricane gathering strength over the Gulf of Mexico and aiming at the densest concentration of American oil refining on earth. The other is a war in the Persian Gulf that was meant to be winding down and, by most measures, is quietly starting up again.
Anyone who spent the summer convinced the worst had passed should study Thursday’s tape again. In June, Washington and Tehran signed a memorandum of understanding in a burst of optimism, then largely ignored it. July brought the truce’s collapse, when the Revolutionary Guard struck three ships in the Strait of Hormuz and the White House answered with hundreds of strikes on Iranian targets. A lull followed in August, and a lull is dangerous, because it persuades people that the crisis is over. It never was.
Refineries sit at the centrer of this story for reasons that have nothing to do with romance. Crude in the ground is nearly useless until somebody boils it and splits it into the fuels that move ships, trucks, tractors and aircraft. America’s capacity to do that work is concentrated along a few hundred miles of Gulf coastline between Corpus Christi and Pascagoula. Remove that strip of coast from service, even briefly, and the world does not lose a well. It loses a lung.
The other hinge is narrower still. Roughly twenty million barrels of oil and petroleum liquids pass through the Strait of Hormuz each day, about a fifth of everything the planet burns, and traffic there has fallen by more than ninety percent since late February. Saudi Arabia rerouted what it could through the Red Sea, and the Emiratis pushed crude down a pipeline to Fujairah. Neither workaround replaces what a closed strait removes, and both have themselves been attacked.
Behind those two facts sits a third that receives far less attention and matters a great deal. Fuel is not only fuel. Diesel powers freight, and freight delivers food. Fertiliser is made from natural gas and shipped through the same contested water, and the Middle East supplies close to a quarter of the world’s urea and roughly half of its traded sulphur. Disrupt the Gulf and the price of a tank of petrol is only the beginning; the price of bread, of lettuce, of anything that must travel before it is eaten, rises with it.
What follows is an attempt to set out, plainly, how these two threats reinforce each other, and why the arithmetic points somewhere darker than most forecasts allow. The margin of error that cushioned four decades of cheap energy has been spent. Inventories are thin, the strategic reserve sits at its lowest level since 1982, spare refining capacity outside China is scarce, and the buffer that once absorbed a shock is gone. In a system without slack, small events stop being small.
2027, then, looks like a year of shortages. Not famine, not collapse, not the end of the world, but a grinding, cumulative squeeze on the things ordinary people buy without thinking. That is the claim, and it deserves to be tested rather than asserted, which is why the analysis that follows relies heavily on data.
Half of America’s Fuel Sits Directly in the Storm’s Path: Begin with the geography, because the geography makes the argument. More than half of all United States refining capacity is stacked along the Gulf Coast, and the Texas and Louisiana stretch alone accounts for close to half the national total. On the most recent federal figures, the region holds roughly 9.9 million barrels per day of operable capacity, about fifty-four percent of the country’s total refining capacity. This is where crude becomes petrol, diesel and jet fuel. Nowhere else in the industrialized world matches the concentration.
Isaias is aimed at the northern shore of that same gulf. It formed off eastern Mexico in the first days of October, strengthened into the season’s first Atlantic hurricane, and by Thursday had reached Category 2 with winds near 110 miles per hour, forecast to make landfall late Friday or early Saturday between eastern Louisiana and the Florida Panhandle. No hurricane has struck the United States since Milton in 2024, and this one arrives with the system unusually exposed.

Refinery operators began preparing days before landfall. Shell, Chevron and BP pulled non-essential staff off platforms and throttled production. By midday Thursday, about 1.3 million barrels a day of Gulf oil had been shut in, along with more than half the region’s gas output, and more than 120 offshore platforms had been evacuated. Attention then shifted ashore, to a handful of plants whose importance reaches far beyond their hometowns.
Chevron’s Pascagoula refinery in Mississippi, able to process some 369,000 barrels a day, sits close to the projected track. So do the dense clusters around New Orleans and Baton Rouge, where ExxonMobil, Shell and Valero operate some of the largest and most complex plants in the country. Andy Lipow, a Houston analyst who has watched storms for three decades, placed roughly 2.7 million barrels a day of national refining capacity inside or near the storm’s path and said he expected at least some of those plants to cut runs. His reading of the wider system was blunt: there is no slack anywhere to replace what is lost, so the shortfall must come straight out of already thin commercial inventories.
Shutting down a refinery ahead of a hurricane involves far more than simply switching it off. Plants are built to run continuously for years, and a controlled stop is a delicate, hours-long sequence of cooling, depressurizing and clearing lines. Restarting takes longer and carries more risk, because equipment that has been flooded, starved of power or shaken by wind must be inspected, dried and tested before it can handle hot hydrocarbons again. Even a glancing Category 1 strike usually costs a week of production. A direct hit, with flooding and loss of grid power, can idle a plant for a month.
Multiply that by the number of plants in the danger zone and the national picture sharpens. Florida, which refines almost nothing of its own and depends on tanker deliveries from the Gulf, is the most exposed. Barges and tankers cannot load or unload in a storm, so the disruption reaches well beyond the coastline the hurricane touches, into states that will never see a drop of its rain.
None of this would matter so much if inventories were normal. They are not. Petrol stockpiles recently fell to their lowest seasonal level since 2012, and distillate inventories, which cover diesel and heating oil, sit at their lowest for early October since record-keeping began in the early 1980s. The Strategic Petroleum Reserve holds about 283 million barrels, down from a peak above 700 million, and has been drained repeatedly to soften the war’s price shocks. Refilling it would take years and tens of billions of dollars, and every barrel released now is one that will be missing from the next emergency.
An irony runs through the whole picture. American refineries are running flat out, near ninety-five percent of capacity, precisely because so much refining abroad has been knocked offline. Plants in the Middle East have been damaged or cut off from export terminals, Russian refineries have been hit by Ukrainian drones, and China, hoarding to protect itself, has curbed exports. America has become one of the last reliable sources of refined fuel on the planet, which turns a Gulf Coast hurricane from a regional nuisance into a global event.
Robert Yawger, an energy futures specialist at Mizuho Securities, described the timing in terms that stayed with traders all week. A storm like this could be enormous, he said, and it was arriving at the worst moment in a quarter of a century. He added a warning that deserved more attention than it received: should American refining capacity leave the market, the pressure to ban diesel exports would become almost irresistible, and such a ban would ricochet back into Europe and Latin America.
The forecast, at least, offers some relief. Meteorologists expect Isaias to weaken slightly before landfall and to come ashore east of New Orleans, sparing the Baton Rouge and Mississippi industrial belt the full force of the wind. Weak storms have surprised before, rapidly intensifying ones especially, so the cautious reading is a hit rather than a knockout. Even so, a week of lost runs at a handful of plants is enough to move prices when nothing cushions them.
One wrinkle rarely makes the evening news. Hurricanes do not only shut refineries; they interrupt the pipelines, terminals, docks and power lines that link them, and they scatter the specialized workforce that keeps them running. Restart crews fly in from out of state, and contractors are booked weeks ahead. When several plants are damaged at once, they compete for the same electricians, valves and barges, and a recovery that would take a week for one plant stretches into a month across many. The storm, then, is a threat with a long tail, and that tail runs straight into the second fire.
A Chokepoint That Never Really Reopened: Some nine hundred American and Israeli aircraft opened the war on Iran on the twenty-eighth of February, in an operation the Pentagon named Epic Fury. Within twelve hours they had struck missile batteries, air defenses and leadership targets, killing the Supreme Leader, Ali Khamenei. Iran answered with hundreds of ballistic missiles and thousands of drones aimed at Israel and American bases across the Gulf. Then it chose a cheaper, older and far more damaging response: it closed the Strait of Hormuz.
Shipping traffic fell by seventy percent within hours and by more than ninety percent within days. Tankers stopped broadcasting their positions, insurers withdrew cover for the passage, and within a fortnight the waterway that carries a fifth of the world’s oil had become a war zone. Iran laid mines, harried hulls with fast boats, spoofed satellite navigation and, at least once, charged a ship two million dollars to use its makeshift channel north of Larak Island. By late April, some two thousand vessels and twenty thousand mariners were stranded inside the Gulf.
Prices told the story faster than any diplomat. Brent, near seventy dollars before the war, breached a hundred in March for the first time in four years and peaked near $126, while Dubai crude, the benchmark for the Gulf’s own exports, touched a record $166. March produced the largest monthly increase in the history of the oil market, and analysts reached for the only comparison that fit: the supply shocks of the 1970s. By the numbers, this was the biggest disruption to world energy supply in half a century.
An April ceasefire bought two weeks. Talks in Islamabad collapsed, Washington blockaded Iranian ports in response, and Iran declared the strait shut to any ship bound to or from the ports of America, Israel and their allies. A memorandum of understanding in June, signed by both presidents, promised an end to the war and the blockades; it lasted a month. In July the truce broke down again, the Revolutionary Guard hit three ships, and American aircraft struck some 140 targets in a single night.
Through all of it, the strait has never fully reopened, and that is the detail that matters most for next year. A chokepoint does not need to be sealed to do damage; it only needs to be unreliable. Shipping lines and insurers both price risk, and both add cost to every barrel that passes. Even a partial reopening leaves a permanent tax on the world’s energy, paid at the pump and in the supermarket.
Set out in sequence, the more worrying features of the standoff look like this.The strait is still contested. Iran’s parliament speaker said in early October that the waterway would not reopen until Washington met seven conditions. Washington rejected Tehran’s counter-proposal. Neither side has moved. The truce is a fiction. The June memorandum is described by both governments as effectively defunct, and the two sides have traded fire as recently as September, when the United States attacked three Iranian ships and Iran fired ballistic missiles at an American carrier group.
Washington has put a date on the next round. President Trump said on the eighth of October that the United States would not resume large-scale strikes before the third of November midterm elections, a statement widely read as a promise to bomb after them. Tehran has heard that promise. Iranian commanders have publicly threatened pre-emptive attacks if they conclude an assault is coming, which turns an American election calendar into a deadline for the entire Gulf.
Iran’s grip is loosening, but slowly. The regime consolidated under hard-liners after Khamenei’s death, and the new leadership has staked its legitimacy on holding the strait. The Houthis have opened a second front. Attacks from Yemen have hit Saudi airports and forced Riyadh to reroute exports, removing a workaround that had been keeping some oil flowing. Mines are still being cleared. American warships swept the main shipping lane in late August and identified more than a hundred suspected mines. Sweeping is slow, and a single missed device can close a lane again.
The insurance market has not recovered. War-risk premiums on Gulf voyages remain elevated, and without cover, ships do not sail no matter how calm the water looks. Refining, not just crude, has been hit. Plants across the Gulf have been damaged or cut off from export terminals, which is why America’s own refineries are running so hard. Russia is a second drain on supply. Ukrainian drone strikes have knocked out Russian refining capacity, and Moscow is now earning a windfall from higher prices rather than easing the shortage. China is hoarding. Beijing has restricted fuel and fertilizer exports to shield its own consumers, exporting its shortage to everyone else. Emergency reserves have been spent. The International Energy Agency coordinated a release of 400 million barrels from member stockpiles, and America’s own reserve is at its lowest since 1982.
The war has a body count at sea. At least ninety ships have been attacked, twenty-four seafarers have died, and a cruise ship has been caught in the crossfire, which is exactly the sort of detail that keeps crews away. The deadlock is structural. Iran cannot afford to look weak, America cannot afford to look defeated, and Israel has its own reasons to keep pressure on, so the parties have every incentive to keep the conflict simmering rather than settle it.
Laid out that way, the standoff reads less like a war winding down than a war waiting for a reason to restart. Its most dangerous feature is the calendar. Announcing that you will not attack until after an election tells your enemy how much time they have to prepare and hands them a date to brace for. Armies that expect an assault sometimes strike first, and Iranian commanders have said as much in public.
A complication that rarely makes the news concerns the bomb. Iran’s nuclear program was the stated reason for the war, and Israel claims the strikes set it back years. Whether that is true remains genuinely uncertain, since inspectors have had only partial access since February and the enrichment sites were buried deep before the first bomb fell. If Tehran concludes it has both a window and a grievance, the temptation to sprint toward a weapon, or the appearance of one, grows by the week.
Place the two fires side by side and the logic of Thursday’s price move becomes obvious. One threatens to remove refining capacity from the market; the other threatens to remove crude. Between them they squeeze the same supply chain from both ends, in the same season, with no clean resolution in sight.
What 2027 Already Knows: Forecasting humbles anyone who tries it, so let me be careful about where evidence ends and judgement begins. The facts above are documented; what follows is inference and should be read that way.
The first inference is that the squeeze reaches well beyond the price of petrol. Diesel is the connective tissue of the modern economy, and its cost has already passed six dollars a gallon in America and higher still in parts of Europe. Trucking fleets, which run on thin margins, are being squeezed hard. The American Transportation Research Institute put the average cost of operating a heavy truck at a record $2.34 a mile in 2025, with fuel alone near a fifth of that. Every cent added at the pump feeds straight into the price of everything that moves, and almost everything moves.
Freight is where the arithmetic turns cruel. A refrigerated load of lettuce trucked from California’s Salinas Valley to New York now runs to roughly $10,000, of which about $4,200 is diesel alone; the fuel bill for the same run a year ago came to around $2,700. The carrier does not absorb the difference, and neither does the supermarket. It lands on the shelf, in the produce aisle, on the price of the things hardest to substitute and easiest to notice.
Fertilizer closes the circuit, and here the picture is bleaker than the headlines suggest. The World Bank’s fertilizer price index rose more than twelve percent in the first quarter of 2026, its sixth increase in seven quarters, reaching by April its highest level since October 2022. Urea climbed above $850 a metric ton, up eighty percent in two months. The Middle East supplies around a quarter of the world’s urea exports, roughly a third of its traded sulphur and a similar share of its ammonia, and the strait that carries them is the one Iran has closed. Iran halted ammonia production, Qatar suspended urea, ammonia and sulphur output after damage to its plants, and India cut its own output for want of gas.
Farmers are famously adaptive, but fertilizer is not optional. Skimp on nitrogen one season and the next harvest shows it. The International Chamber of Commerce has warned that grain prices could climb by as much as eighty percent if the disruptions persist, and the World Bank expects its fertilizer index to end 2026 more than thirty percent higher than it began. A farmer paying more for inputs while facing an uncertain price for the harvest does the rational thing: plants less, or plants cheaply. Both cut supply exactly when the world needs more.
The bond market has noticed. The correlation between West Texas Intermediate and the ten-year Treasury yield reached 0.96 in September, the tightest link since 2019, which means the oil price is now steering the price of money. Yields have climbed from 4.19 percent at the start of the year to well above five, and rising yields lift mortgages, car loans and corporate borrowing in step. An energy shock that began in a distant waterway is turning up in the monthly payment on an ordinary house.
Europe and Asia are more exposed still. Europe draws more than a tenth of its liquefied natural gas from Qatar through the strait, and its gas prices spiked from around thirty euros a megawatt hour to above sixty before settling in the high forties; the European Union absorbed more than thirty billion euros in extra fossil fuel import costs by early May alone. Asian buyers, who once took roughly eighty-four percent of the crude flowing through Hormuz, now bid against each other for whatever barrels remain, and the weakest importers, India, Pakistan, Bangladesh and much of Africa, are priced out first.
None of this has yet produced a recession, which is worth stating plainly, since forecasts of doom are cheap. The IMF in fact revised world growth upward for 2026, to about three percent, and expects slightly better in 2027, on the strength of an artificial intelligence investment boom that has kept demand and employment buoyant even as energy costs bite. The honest framing, then, is not collapse but a squeeze that grinds rather than breaks, and grinds hardest on those with the least room to absorb it.
Three assumptions underpin that relatively benign outlook, and all three are fragile. The first is that Isaias spares the refineries. The second concerns the Gulf standoff, which has to stay a simmer rather than a boil. And the third is that the world’s thin inventories are not tested again before they can be rebuilt. If all three hold, 2027 will be uncomfortable; if one fails, ugly; if two fail at once, the shortages of the late 1970s become the right reference point rather than a rhetorical flourish.
Watching from the outside, as someone who reads these numbers for pleasure and keeps a tally of how often the comfortable consensus has been wrong, what stands out is how little room the system retains. Cheap energy built a world of deep inventories and idle capacity, and both have been spent. The reserve is drained, the refineries run flat out, the ships hide, and the harvest depends on fertilizer that must cross a contested strait. A generation grew up assuming the buffer would always be there. It is gone, and 2027 is the year that becomes hard to ignore.
The temptation in the months ahead will be to treat each shock as it comes and to assume the next will be milder. That was the mood in June, when a memorandum was signed and the oil price slid, and it lasted about four weeks. This year’s pattern suggests the opposite habit is wiser: expect the shocks to keep coming, the buffers to keep thinning, and the two fires in the two gulfs to keep burning.
A final observation, offered as opinion rather than fact. The most underrated variable here is not a pipeline or a strait but patience. Washington has elections, Tehran has a proud new leadership with something to prove, and both answer to constituencies that reward firmness over compromise. Every month the standoff continues, the pressure to settle it militarily grows, and each strike risks something no one can easily replace. That is how a war nobody wanted becomes a war nobody can stop.
Keep an eye, then, on two things next year, and on one date in particular. Watch the Gulf weather, because a single bad landfall can undo a decade of refining capacity in a week. Watch the strait, because it carries a fifth of everything the world burns and has not been reliably open since February. Circle early November, when an American election gives the war a schedule it did not have before. If both fires still burn by then, 2027 will not merely be a year of shortages. It will be the year the world runs out of room to absorb them."
