If You Think Mining the Strait of Hormuz Is Bad, I Can Tell You It’s Even Worse Than That
A data-driven deep dive into the world’s most dangerous chokepoint, the economics of closure, and why the coming months could reshape global energy markets.
Let me be blunt. Most people reading headlines about the Strait of Hormuz right now are still underestimating what is happening. They see “oil prices up” and think it is another Middle East scare that will fade. They think the U.S. Navy will sort it out. They think there are workarounds. There are not — at least not at the scale required. And mining makes everything exponentially harder to fix.
Today, March 10, 2026, Iran has begun laying naval mines in the Strait of Hormuz. Only a few dozen so far, according to U.S. intelligence. But Iran retains roughly 80 to 90 percent of its mine-laying capacity, meaning hundreds or thousands more could follow. The IRGC effectively controls the waterway. Commercial traffic has collapsed. Brent crude has already spiked from the mid-$60s to above $90 in a matter of days, briefly touching $120. And we are still in the opening act.
To understand why this situation is worse than most people realize, you need to understand three things: how much of the global economy flows through this 21-mile-wide channel, why there is almost no way to reroute that flow, and why even a modest disruption causes a disproportionate explosion in prices. Then you need to understand that mines — cheap, simple, and terrifyingly effective — make the problem last not days, but weeks or months. Let me walk you through each of these, with data.
The Strait: A One-Fifth Share of Everything
The Strait of Hormuz is not merely an important shipping lane. It is the single largest bottleneck in the global energy system. According to the EIA’s chokepoint analysis, in the first half of 2025 approximately 20.9 million barrels per day of oil transited the strait. That represents roughly 20 percent of total global petroleum liquids consumption and about 25 percent of all maritime-traded oil worldwide. On the LNG side, 11.4 billion cubic feet per day moved through Hormuz in the same period — over 20 percent of global LNG trade, almost entirely originating from Qatar.
To put the oil number in physical terms, converting 20.7 million barrels per day (the 2024 figure) using standard industry approximations yields approximately 1.03 billion tonnes per year. That is a staggering mass of hydrocarbons funneling through a channel barely wider than the English Channel at its narrowest.
The flow has been remarkably consistent over time. In 2020, during the worst of the COVID demand crash, volumes dipped to 19.2 mb/d. They rebounded to 21.9 mb/d by 2022 and settled around 20.7 to 20.9 in 2024 and 1H25. What has shifted somewhat is the composition — crude and condensate volumes fell by about 1.5 mb/d from their 2022 peak, partially offset by a rise of roughly 0.5 mb/d in refined product shipments. But the total remains enormous and essentially irreplaceable in the short term.
The concentration of this traffic going to a single region makes the geopolitical stakes even sharper. The EIA estimates that roughly 89 percent of all crude oil and condensate transiting Hormuz in the first half of 2025 was destined for Asian markets. China, India, Japan, and South Korea alone accounted for about 74 percent. These four economies are not peripheral players; they represent a massive share of global manufacturing, trade, and consumption. When Hormuz stops flowing, it is not a localized Gulf problem. It is an Asian industrial crisis with global transmission.
There Is No Plan B (Not a Real One)
Here is the part that separates the Strait of Hormuz from other chokepoints like the Suez Canal or the Panama Canal. When Suez is disrupted, ships reroute around the Cape of Good Hope. It costs more and takes longer, but the oil still moves. With Hormuz, there is no sea route alternative from inside the Persian Gulf to the open ocean. The only “alternatives” are a handful of pipelines that bypass the strait entirely — and their combined capacity falls catastrophically short.
The EIA estimates that Saudi Arabia’s East-West Pipeline plus the UAE’s Abu Dhabi crude export pipeline could together provide approximately 4.7 mb/d of bypass capacity. Iran’s Goreh–Jask pipeline adds a further 0.3 mb/d. That totals roughly 5.0 mb/d. Against a baseline flow of 20.9 mb/d, this means approximately 15.9 mb/d — about three-quarters of total Hormuz oil transit — would be effectively stranded under a full closure, before any demand destruction, strategic reserve releases, or other emergency measures come into play.
For LNG, the situation is even more dire. There are no pipeline alternatives at anything approaching the scale of Qatar’s LNG exports. The 11.4 Bcf/d flowing through Hormuz in 1H25 is essentially a near-total loss in a closure scenario. That is not a rounding error. It is the heating, power generation, and industrial feedstock for large parts of Asia, and increasingly Europe, simply disappearing from the market.
Why Even a Small Shortfall Breaks the Market
This is where the economics become genuinely frightening. Oil markets are not like, say, the market for smartphones. In the short run, both supply and demand for oil are widely estimated to be highly price-inelastic. A Bank of Canada working paper on oil price elasticities targets short-run elasticities of approximately 0.10 for supply and negative 0.10 for demand — consistent with what it describes as “conventional” views. The Federal Reserve Board has published similar estimates.
What this means in plain terms is that neither producers nor consumers can rapidly adjust to a supply shock. Producers cannot meaningfully ramp up output in weeks. Consumers cannot switch to alternatives overnight. Cars still need gasoline. Factories still need diesel. Power plants in Asia that run on LNG do not have a backup switch to flip.
In a simplified equilibrium framework, if you take the price sensitivity formula — the price increase equals the shortfall fraction divided by the sum of supply and demand elasticities — a net global shortfall of 7 percent implies a roughly 35 percent price increase. A 15 percent shortfall implies approximately 75 percent. These are not extreme assumptions. They are the central-bank consensus applied to the actual volume at risk.
Brent crude was trading around $65 per barrel in late February 2026 before the U.S.-Israeli strikes on Iran began on February 28. Within days, it spiked above $90 and briefly touched $120. As of today, with confirmed mining activity and the effective closure still in force, Brent sits around $90 with extreme intraday volatility. Rystad Energy has projected that if conditions persist for four months, Brent could reach $135 per barrel. History says this is not hyperbole.
A Decade of Crises — and the Biggest One Yet
To put the current price action in context, consider what has happened to oil over the past decade. The 2014 price crash took Brent from $110 to $30 over the course of 18 months as Saudi Arabia flooded the market and U.S. shale production surged. COVID-19 crashed prices to $26 in April 2020. The Russian invasion of Ukraine in February 2022 sent Brent to $128 on supply fears. Each of these was a major event that reshaped energy markets for months or years.
The Hormuz crisis has the potential to be larger than any of them. The 1973 Arab oil embargo — which removed about 5 mb/d from global markets — triggered a 300 percent price increase and reshaped the geopolitical order of the late twentieth century. The current situation puts 15.9 mb/d at risk. Even with mitigating factors like strategic petroleum reserves, OPEC spare capacity (largely in the very countries whose exports are blocked), and demand destruction, the math is sobering. The scale of the potential disruption is three times larger than the embargo that defined a generation.
The Mine Problem: Cheap to Deploy, Expensive to Clear
Now we arrive at the part of this story that transforms a crisis into a potentially prolonged catastrophe. Naval mines are among the most cost-effective weapons in any military’s arsenal. A single mine can cost as little as $1,500. When one struck the USS Samuel B. Roberts in 1988 in the Persian Gulf, the repair and transport costs exceeded $96 million — a cost ratio of roughly 1 to 64,000. Another mine damaged the USS Tripoli during the Gulf War. Since 1950, mines have been responsible for 77 percent of U.S. ship casualties.
Iran possesses a substantial mine inventory. Estimates from the Strauss Center at the University of Texas place the stockpile at a minimum of 2,000 mines, while the U.S. Defense Intelligence Agency has estimated upwards of 5,000 to 6,000 — including both simple moored contact mines and more advanced influence mines that trigger based on a ship’s magnetic, acoustic, or pressure signature. These more sophisticated types are significantly harder to detect and neutralize.
The operational logic for Iran is straightforward and ruthless. The Strait of Hormuz is narrow enough that even a moderate number of mines in the right locations can make the navigable channels impassable for commercial shipping. It is not necessary to lay a perfect barrier. All you need to create is doubt. The mere suspicion that mines may be present causes commercial shipping to halt because insurers withdraw coverage. Protection and indemnity insurance was pulled for Hormuz transits by March 5. No insurance means no shipping. The threat can be as effective as the weapon itself.
The Demining Reality: Weeks at Best, Months at Worst
Mine countermeasures — the military term for finding and clearing mines — is one of the most technically demanding and time-consuming naval operations that exist. The U.S. Government Accountability Office breaks the process into three phases: mine hunting (detecting, locating, and classifying), sweeping (towing equipment to cut moored mines or trigger influence mines by simulating ship signatures), and neutralization (destroying or removing the mines). Each phase is fraught with difficulty.
The first challenge is detection. Bottom mines and influence mines sitting on the seabed in shallow coastal waters are exceptionally hard to distinguish from natural clutter — rocks, debris, old equipment. Every false alarm requires time and resources to investigate. In the Hormuz environment, where the bottom is littered with decades of maritime activity, false alarm rates can be extremely high. The clearance problem is not just about neutralizing mines; it is about proving to commercial insurers and shipowners that the residual risk has dropped to an acceptable level.
The second challenge is operational access. Mine countermeasure ships, unmanned underwater vehicles, and helicopter-towed sweep systems must operate in the minefield zone, which in this scenario is also within range of Iranian anti-ship missiles, drone swarms, and shore-based missile batteries. Iran has built what defense analysts describe as a layered anti-access strategy specifically designed to make mine clearance operations difficult and dangerous. MCM forces need protection, which diverts warships from other tasks and complicates the operational picture.
The third challenge is re-mining. Clearance is a one-time engineering task only if the adversary stops laying mines. If Iran can re-seed mines faster than coalition forces can clear them — which is entirely feasible given the asymmetry between laying (fast, cheap, dispersed) and clearing (slow, expensive, concentrated) — then the problem shifts from a fixed obstacle to a running contest. This is the nightmare scenario that pushes timelines from weeks into months.
Under the best-case scenario — limited mining focused on intimidation, with a rapid international mine countermeasure surge and minimal re-mining pressure — a commercially acceptable corridor could be reopened in roughly two weeks, with throughput restored to about 65 percent of baseline. The mid-case scenario — a moderate barrier minefield in the traffic separation scheme lanes, with sustained MCM operations and a convoy regime — extends the timeline to four to eight weeks, with throughput around 35 percent during that period. The worst case — extensive layered mining with significant influence and bottom mine types, conducted under ongoing military threat with active re-mining — could push full clearance out to two to four months or longer. In this scenario, oil throughput would be limited to pipeline bypass capacity alone — about 5 mb/d out of a 20.9 mb/d baseline.
Who Gets Hurt: A Map of Global Pain
The distributional impact of a Hormuz disruption is profoundly uneven. Asia bears the overwhelming brunt. China imports approximately 5.8 mb/d of crude through the strait, India around 4.6 mb/d, Japan 2.7 mb/d, and South Korea 2.3 mb/d. For India in particular, oil imports represent a much larger share of GDP than for wealthier nations, making the economic shock proportionally more severe. India is arguably the most vulnerable major economy on the planet to a Hormuz closure.
The Gulf Cooperation Council (GCC) exporters face a crisis of a different kind. Saudi Arabia, Iraq, the UAE, and Kuwait cannot export the vast majority of their oil. Their fiscal models depend on export revenue. Saudi Arabia alone ships approximately 5.8 mb/d through Hormuz. While the East-West Pipeline provides some bypass capacity, it was not designed to replace seaborne exports at scale or indefinitely. For Iraq, which has no meaningful bypass infrastructure at all, the situation is a fiscal emergency from day one.
Europe, while less directly exposed than Asia, is hit through two channels: global oil price transmission and LNG competition. European LNG importers who were already competing with Asian buyers following the post-Ukraine supply reshuffling now face an even tighter market. The United States has the smallest direct exposure — the EIA estimates only about 0.4 mb/d of U.S. crude imports transit Hormuz in 1H25, roughly 7 percent of total U.S. crude and condensate imports. But the U.S. is not insulated from global price effects. Oil is a globally priced commodity. When prices spike in Asia, they spike everywhere.
What Happens Next: Scenarios and Their Price Tags
The situation as it stands today is fluid and dangerous. Iran has confirmed the strait is closed to U.S., Israeli, and Western-allied shipping. The IRGC has attacked at least ten vessels since February 28. Mining activity has been detected and is expected to escalate. The U.S. military has sunk more than 50 Iranian naval vessels and is actively targeting mine-laying craft and storage facilities, but has not yet established escorted shipping lanes — despite a premature and subsequently retracted claim by the U.S. Energy Secretary on this very topic earlier today.
Three scenarios bracket the likely outcomes over the coming weeks and months. In the optimistic scenario, diplomatic pressure, military action against mine-laying assets, and a combination of strategic reserve releases bring the crisis to a manageable state within a few weeks. Oil prices settle in the $75-85 range as limited convoy operations resume. This requires Iran to stop mining and accept military losses without further escalation.
In the mid-range scenario, mining continues intermittently, clearance operations proceed slowly under threat, and convoy-escorted traffic resumes at reduced capacity over four to eight weeks. Oil prices trade in the $100-120 range for an extended period, triggering demand destruction in the most price-sensitive economies and a significant global economic slowdown. Strategic reserves are drawn down significantly.
In the pessimistic scenario, extensive mining combined with ongoing Iranian anti-access operations keeps the strait effectively closed for two to four months or longer. Oil prices breach $130 and potentially approach or exceed $150. The economic consequences at this level are recessionary for much of the world. LNG prices in Asia reach crisis levels, with cascading effects on electricity prices, industrial production, and food costs (through fertilizer and transportation inputs). This is not the 1973 embargo. It is worse, because the volumes are larger, the global economy is more interconnected, and the weapons being used to enforce the closure are harder to counter.
The Bottom Line
The Strait of Hormuz crisis is not a geopolitical risk scenario that analysts dust off for conference presentations. It is happening right now, in real time. Mines are being laid in the water. Ships are being attacked. Oil that supplies one-fifth of the world is not flowing. The bypass infrastructure that exists covers barely a quarter of the gap. And the physics of mine warfare — cheap to deploy, slow to clear, devastating in effect — mean that this disruption is measured in weeks and months, not days.
If you hold energy exposure, you are watching the single most consequential supply event since the 1970s unfold. If you do not hold energy exposure, you are about to feel it anyway — at the gas pump, in shipping costs, in inflation prints, and in the GDP data of every import-dependent economy on the planet. The data says this clearly. The market, I suspect, has not yet fully priced it in.
Stay sharp.

The part I think the market still underestimates is the timeline mismatch.
Even if the military phase de-escalates faster than expected, insurance, clearance, and shipping normalization do not. That means the economic shock can outlast the headline shock by weeks or months.
Markets usually price the ceasefire first and the logistical reality later. In situations like this, that gap is where a lot of the mispricing lives.
