The Prize, Reweighed: How a War in the Gulf Rewrote Oil's Rulebook in Six Months

Daniel Yergin spent nearly nine hundred pages arguing that oil is never just a commodity. It is leverage, it is empire, it is the thing nations have gone to war over more often than almost anything else on earth, and every era of oil politics eventually produces its own defining chokepoint. For the last several decades that chokepoint has been the Strait of Hormuz, the narrow channel between Iran and Oman through which roughly a fifth of the world's oil and liquefied natural gas has traditionally passed. Since the morning of 28 February 2026, when the United States and Israel launched their opening strikes on Iran, that strait has been effectively closed, and the global oil market has spent six months reorganizing itself around the absence of a route it had taken for granted for half a century.

The scale of the disruption is difficult to overstate. OPEC's own figures show total OPEC+ production collapsing from 42.77 million barrels per day in February, the day before the war began, to just 33.13 million barrels per day by May, a drop that reflects not a deliberate policy choice but a genuine physical constraint: with Hormuz closed to normal traffic, the region's storage capacity filled up with crude that had nowhere to go, forcing producers to throttle output regardless of what their production quotas said on paper. Market analysts have been blunt about what this means for OPEC+'s usual toolkit. When the group announced a fifth consecutive monthly output increase in July, adding 188,000 barrels per day among seven member states including Saudi Arabia, Russia, Iraq, and Oman, one Sydney-based analyst described the move as largely a "paper formality," since actual barrels reaching the market have been constrained for months by the blockade regardless of what quotas allow.

Prices have told the same story with less nuance. Brent crude was trading at $72.48 a barrel on 27 February, the day before the war started — a fairly ordinary level by recent historical standards. By early September, crude was trading near $91 a barrel, up roughly 21 percent over the preceding month alone and up nearly 47 percent compared to the same point a year earlier, driven by renewed hostilities at the end of August and mounting uncertainty over whether Hormuz shipping will ever fully normalize while the war continues. Confirmed market data shows this is not a smooth, one-directional climb. Prices have whipsawed with every ceasefire rumor and every fresh exchange of strikes, a pattern that reflects just how thin the market's patience has become after six months of living with this level of uncertainty priced into every barrel.

A CARTEL MANAGING SCARCITY IT DID NOT CHOOSE

What makes this moment genuinely unusual in the long history Yergin documented is that OPEC+ finds itself, for the first time in years, managing an involuntary scarcity rather than engineering a chosen one. The cartel has spent much of the past three years gradually unwinding voluntary production cuts first announced in 2023, a process aimed at slowly returning barrels to a market that had grown used to tighter supply. The Iran war interrupted that process entirely. A separate curtailment of roughly two million barrels per day, unrelated to the war and tied to the group's own longer-term supply management strategy, remains in place through the end of 2026, layered on top of whatever the Hormuz closure has already removed from the market. Analysts tracking the group's institutional behavior describe this as evidence that OPEC has evolved from a simple price-fixing cartel into something closer to a market governance institution, one now forced to calibrate two entirely separate supply constraints, one chosen and one imposed by war, at the same time.

The International Energy Agency's own numbers capture the paradox at the heart of this market. Global oil supply is now forecast to fall by 4.3 million barrels per day in 2026, driven overwhelmingly by losses in the Middle East and Russia that outpace even a healthy 1.4 million barrel per day growth from American producers. Yet global demand is falling too, by an estimated 1.6 million barrels per day, as the closure of Hormuz and the resulting elevated fuel prices weigh directly on consumption in exactly the economies that would otherwise be buying more oil, not less. This is the strange mathematics of a war-disrupted commodity market: supply and demand are both shrinking simultaneously, and prices are being set less by the balance between the two than by fear of what happens if the war escalates further before either side has time to adjust.

American shale producers, long treated as the market's flexible swing supplier during previous periods of Middle East turmoil, have not stepped in to fill the gap this time. The US Energy Information Administration now expects American oil production to fall to 13.28 million barrels per day in 2026, the first annual decline in domestic output since 2021, as shale companies cut back drilling in response to a price environment that swung too low for too long earlier in the cycle before this year's war-driven spike arrived. The number of active US oil rigs has fallen to a three-and-a-half-year low of around 410, a signal that American producers are not yet convinced the current elevated prices will hold long enough to justify the capital expenditure that new drilling requires. In Yergin's framework, this is the moment where the "prize" briefly slips from the hands of whoever can pump the most oil and into the hands of whoever can most credibly promise stability, a currency in shorter supply this year than crude itself.

For countries like Bangladesh, which import essentially all of their crude and refined petroleum needs, this six-month disruption has arrived as a direct hit to import bills, fertilizer costs, and transport prices at a moment when the domestic economy can least absorb it. Every dollar added to the price of a barrel in Rotterdam or Singapore eventually shows up in the price of diesel at a filling station in Dhaka or Chattogram, with a lag measured in weeks rather than months. Energy security planners across South Asia have spent this year relearning a lesson that Gulf-adjacent economies never really forgot: dependence on a single maritime chokepoint, however efficient it has been for decades, is also a standing vulnerability that a single war on the other side of the world can activate at any time.

The financing side of this story deserves equal attention, because higher oil import bills do not simply raise pump prices, they widen current account deficits and put pressure on foreign exchange reserves in exactly the kind of economies least equipped to absorb the shock. Governments that subsidize fuel domestically, as several South Asian states have done for decades, now face the same uncomfortable choice they faced during the last major oil shock: pass the higher cost on to consumers and risk public anger, or absorb it into the budget and risk the kind of fiscal strain that eventually shows up in credit ratings and borrowing costs. Neither option is free, and both were far easier to postpone before this war made a fifth of the world's oil supply, at least on paper, hostage to the security situation around a single strait.

THE PAPYRUS VERDICT

OPEC+'s output increases this year have been more theater than substance, a signal to markets that the cartel intends to normalize supply the moment Hormuz reopens, without any actual ability to deliver on that signal while the strait remains contested. The real story is not the quota headlines but the physical arithmetic: falling global supply meeting falling global demand, with price acting as the shock absorber for a war neither side shows signs of ending soon. Expect prices to remain volatile and headline-driven rather than settling into a stable band as long as fighting continues near the Gulf, expect American shale to stay cautious rather than rushing back in, and expect import-dependent economies, Bangladesh among them, to keep treating every ceasefire rumor out of Tehran or Washington as a piece of economic news as much as a diplomatic one.
