The Strait That Prints Money: Inside the Hidden Economics of Hormuz

There is a version of the Strait of Hormuz story that you have already been told. It goes something like this: Iran, a belligerent state with a long record of destabilizing its neighborhood, has decided to play its oldest card and threaten the world’s most critical oil passage. 20% of global petroleum, moving through a corridor barely 40 kms wide at its narrowest point. The United States, with its Israeli ally, responded militarily. A crisis broke out. The world held its breath.

That version of events is not wrong. It is simply incomplete.

Because running alongside the geopolitical drama, visible in exchange data and financial filings if you care to look, is a 2nd story. A story about who profits when a civilization-level supply chain convulses. And, crucially, a story about whether the convulsions themselves are being scheduled for someone’s benefit.

In 2024, oil flows through the Strait of Hormuz averaged 20 million barrels per day, equivalent to roughly 20% of global petroleum liquids consumption. Around 1/5th of global liquefied natural gas trade also passed through the strait, primarily from Qatar.

That concentration of economic dependency in one narrow chokepoint is staggering. What makes the current episode different from previous geopolitical oil shocks is first and foremost its magnitude. In 1973 and 1990 only a little more than 6% of global oil supplies were removed from the market. In 1979 and 1980, only about 4%. The current disruption involves a shortfall close to 20%, making it three to five times larger than any prior geopolitical oil shock in recorded history.

The head of the International Energy Agency, Fatih Birol, has described the shipping crisis in the Strait as “the largest supply disruption in the history of the global oil market.”

This is the backdrop. Now consider what that backdrop is worth to someone who knew, even hours in advance, which direction prices were about to move.

On the morning of March 23, 2026, something unusual happened in the oil futures market. Traders placed a massive, one-way bet on falling oil prices just minutes before Donald Trump announced he was pausing planned strikes on Iranian power plants and claimed there had been “productive conversations” with Tehran. According to the Financial Times, roughly 6,200 Brent and West Texas Intermediate contracts changed hands between 6:49 and 6:50 a.m. in New York, about 15 minutes before Trump’s Truth Social post signaling potential de-escalation, a message that immediately sent oil sharply lower and lifted stock index futures.

The notional value of massive blocks of West Texas Intermediate and Brent futures contracts traded in just one minute, 15 minutes before the post, is estimated at about $580 million, per Financial Times calculations based on Bloomberg data.

To put that number in perspective, $580 million moved in 60 seconds in a direction that would only make sense if the mover already knew what the president was about to post publicly. If that was a coincidence, it is one of the most expensive coincidences in financial history.

This was not a one-off anomaly. Thousands of short positions on oil prices were placed on April 7, 2026, minutes before Trump announced a ceasefire with Iran on his social network, Truth Social. The evidence aligns with a reported pattern of well-timed bets set to benefit from major decisions of his administration that, according to experts the BBC consulted, may suggest insider trading.

Journalists and analysts have described an epidemic of such trades and coined a trader nickname for the phenomenon: the “TACO trade,” which frames the pattern as deliberate front-running of predictable presidential behavior.

The language is flippant but the math is not. The pattern is too consistent to be statistical noise. What it reveals is a market that has learned to read one man’s social media posts before he publishes them.

The oil futures market operates in a world of institutional finance, clearing houses, and regulatory oversight. Whatever its current dysfunctions, there is at least a paper trail. Far murkier is what has been happening simultaneously on the new prediction platforms that have surged to prominence under this administration’s approving eye.

At least 50 brand new accounts on Polymarket placed substantial bets on a US-Iran ceasefire in the hours, even minutes, before President Trump announced the ceasefire late on April 7. These were the sole bets ever made through these new accounts.

One account, created on the day of the ceasefire announcement, placed roughly $72,000 in bets at an average price of $0.088 and cashed out for a profit of $200,000. Another wallet, which joined the platform the day before, won over $125,500. A third wallet, created just twelve minutes before Trump’s post, placed $31,908 in bets and earned an estimated profit of $48,500.

These are not sophisticated trading operations. They are throwaway accounts that placed one bet, won, and fell silent. Earlier in the same conflict period, another account that placed bets on the ceasefire was found to have placed winning bets on the United States and Israel striking Iran on February 28, the day the war began. That account was created just before the start of the war and has not made any other bets.

It is also worth noting who has financial interests in these platforms. Donald Trump Jr. is an investor in Polymarket through his venture capital firm, 1789 Capital, and separately serves as a paid strategic adviser to Kalshi. The Commodity Futures Trading Commission, whose chairman has said he would back Kalshi in any legal battles at the state level, is effectively controlled by the Trump administration. Any friendly regulatory decision that the CFTC makes on this industry could end up financially benefiting the US president’s family.

The regulatory body tasked with policing the industry is run by someone aligned with an administration whose family profits from that industry. One does not need to allege conspiracy to find this arrangement troubling. The structure itself creates the problem.

So,

A president who controls military escalation also controls, with some reliability, the price of oil. That is not a new observation. What is new is the granularity with which that control is being exercised, and the frequency with which it appears to benefit specific financial positions.

When the markets have flashed danger, Trump has been quick with a social media post or a remark claiming the war he launched could soon end. He has publicly declared that the markets are doing better than he expected, even with the S&P 500 declining over a five-week period and the global oil benchmark up roughly 60%. “I thought oil prices were going to go up higher than they are now,” Trump said at a Friday investor summit. “And I thought that we would see a bigger drop in stock.”

That sentence deserves careful reading. A sitting president publicly reflects on his expectations for how much the market would drop, as though the variable he was tracking was always price movement, not the human cost of a war he initiated.

Oil market analyst Rory Johnston, speaking to Fortune, said the pattern has been hard to ignore even without a smoking gun. “Everyone, every analyst, every oil trader, has been questioning downward pressure on prices.” He added that whether or not there has been direct market manipulation by Washington, the administration’s public statements have spooked participants out of trading where physical fundamentals would otherwise push prices higher.

The effect, in other words, exists regardless of the intent. Someone profits from a president who treats announcements about war and peace as movable pieces on a board.

And,

It would be too simple to cast this entirely as an American story of financial opportunism. Iran’s behavior throughout this crisis has been, by any measure, its own form of theater.

When Trump announced on March 23 that “productive conversations” with Tehran were underway, Iran’s parliament speaker Mohammad-Bagher Ghalibaf denied that any negotiations had taken place, calling the claim “fake news” used to “manipulate the financial and oil markets.”

Ghalibaf’s denial is worth dwelling on. Whether or not he was accurately describing the situation, an Iranian official essentially confirmed the same hypothesis being offered here: that price-sensitive announcements about this conflict are being weaponized for market gain. He accused the Americans of doing it. The Americans accused the Iranians of escalating for leverage. Both observations can be true at once. What is clear is that each side understands the other well enough to accuse them of the very behavior their own actions encourage.

Iran’s decision to formally close the strait while denying negotiations, only to have ceasefire conditions emerge anyway, creates exactly the violent price oscillation that short-sellers require. A market that swings 10% in a morning, triggered by competing announcements from two governments, is not behaving randomly. It is being played.

Here is what the data, assembled from the Financial Times, Bloomberg, Goldman Sachs, and multiple exchange filings, allows us to describe with reasonable confidence.

Goldman Sachs Research estimated that traders were demanding about $14 more for a barrel of oil than before the conflict began, roughly corresponding to the premium associated with a full four-week halt in Strait flows, as of early March. Brent closed Friday around $73 per barrel, with analysts pointing to an open in the $85 to $90 range the following Monday. Oil markets have since reacted with Brent crude prices rising above $90 per barrel.

Against that backdrop, a trader who moved into short positions on oil just before a de-escalation announcement, or into long positions just before an escalation, would have enjoyed extraordinary returns. The data shows this happened repeatedly. The data does not conclusively prove who was behind it, and that is a distinction that matters enormously for legal purposes.

The top US derivatives regulator is now investigating a series of suspiciously well-timed trades in the oil futures market ahead of recent policy pivots by President Trump related to the war in Iran. That investigation is proceeding inside the same CFTC whose chairman is aligned with the platforms and administration under scrutiny. The fox, to use an old expression, is examining the henhouse.

In 2025, tariff announcements and shifting trade rules had triggered a sharp selloff, with the S&P 500 falling nearly 20% in seven weeks around the April 2 “Liberation Day” briefing before quickly recovering. That episode produced exactly the same pattern: dramatic volatility, followed by a reversal, with someone on the right side of both moves. The Hormuz crisis is not an isolated incident but an acceleration of a pattern that has been visible since the opening months of Trump’s second term.

Hence,

Many oil traders have been in wait-and-see mode, trying to assess how long the disruption will last. Many buyers and refiners are scrambling for alternative crude supplies. Whilst there is not outright panic, the market shows urgency and deep concern, with traders and refiners increasingly worried about prolonged outages.

The consequence of markets being used as instruments of personal enrichment by those with advance knowledge of policy is not only a legal problem. It is a trust problem. When institutional investors understand that a presidential social media post can move oil by 10% in minutes, and that someone appears to be positioned ahead of those posts, they price in a risk premium that ordinary businesses and consumers ultimately absorb. Higher shipping costs, higher fuel costs, higher food prices. The friction of uncertainty, distributed across the whole economy, channeled upward to those who profit from it.

Higher energy, fertilizer, and transport costs, including freight rates, bunker fuel prices, and insurance premiums, may increase food costs and intensify cost-of-living pressures, particularly for the most vulnerable.

This is the part of the story that rarely appears in the financial press because it is not dramatic. A refiner in South Korea paying $4 more per barrel. A farmer in sub-Saharan Africa facing sulfuric acid shortages because the Gulf’s supply chain has seized. A family in Mumbai watching fuel prices climb through an already stretched household budget. These are not the beneficiaries of the strategy. They are its cost.

The evidence assembled above establishes a pattern. It does not establish a crime, because establishing a crime requires proof of specific communications, specific trades by specific identified persons, and specific knowledge of non-public information. None of that has been publicly proven. The CFTC investigation is ongoing. No charges have been filed. The White House has denied everything.

What we can say, based on the public record, is this. An extraordinary volume of oil futures moved in a single minute, at a time and in a direction that only made sense with foreknowledge of a presidential announcement. Dozens of brand-new prediction market accounts placed large, precise bets on geopolitical outcomes minutes before those outcomes were made public, and then went silent. The regulatory body charged with investigating these markets is chaired by someone whose appointment serves the political interests of those under scrutiny. And the president himself has made public statements that suggest his frame of reference for this conflict includes market performance as a metric worth tracking.

Nobel laureate Paul Krugman was not speaking loosely when he asked: “Are decisions about war and peace in part serving the cause of market manipulation rather than the national interest?”

That is not a rhetorical flourish. It is a question the available evidence will not let us dismiss.

The Strait of Hormuz is many things. It is a chokepoint of global energy, a theater of regional power, and a test of international law. It is also, if the evidence is taken seriously, a mechanism. A mechanism that transforms uncertainty into profit, provided you know when the uncertainty is scheduled to resolve.

The ships that cannot pass through it right now are carrying oil that the world needs. The money that moved in the minutes before the announcements about those ships is something different entirely.

Follow that money. The geography is the distraction.
