Traffic through Hormuz is grinding to a halt
For the third consecutive day, American and Iranian forces exchanged strikes across the Persian Gulf, and the world's oil markets answered with a language of their own — Brent crude climbing past $84 a barrel, its highest point in a month. The Strait of Hormuz, that narrow passage through which a fifth of the planet's oil must travel, has become both a military theater and an economic barometer, with shipping traffic cut in half and analysts warning that prices could reach $100 if the standoff endures. Beneath the numbers lies an older story: the fragility of the systems on which modern civilization depends, and how quickly a corridor of water can hold the global economy hostage.
- Three days of US-Iran military strikes have shattered a fragile peace memorandum signed just weeks ago, sending Brent crude surging nearly 12% in two days to $84.91 per barrel — its highest since mid-June.
- Iran's Revolutionary Guard attacked two oil supertankers and struck American military installations in Kuwait and Bahrain, while the US announced a reimposed blockade on Iranian ports and a transit fee for vessels seeking American naval protection.
- Shipping traffic through the Strait of Hormuz collapsed by more than 50%, with only 57 vessels transiting over three days compared to roughly 130 ships per day before hostilities began — captains are simply choosing to wait out the war zone.
- The Trump administration's emergency buffer is nearly gone: heavy drawdowns on the US Strategic Petroleum Reserve have left analysts warning of a 'violent repricing' once that cushion disappears and traders lose faith in supply management.
- The US military insists it is escorting 8.5 million barrels daily through the strait, but markets remain skeptical — TD Securities predicts oil could hit $100 a barrel if physical shortages materialize, a shock that would ripple through every corner of the global economy.
Brent crude surpassed $84 a barrel on Tuesday as the United States and Iran entered a third consecutive day of military exchanges, reviving deep fears about the Strait of Hormuz — the narrow waterway between the Persian Gulf and Arabian Sea through which roughly one-fifth of global oil flows. The 2% jump extended Monday's 9.6% gain, pushing prices to their highest level since mid-June and erasing months of stability that had followed a peace memorandum signed between Washington and Tehran just weeks prior.
The escalation has been swift and mutual. US Central Command launched a third wave of strikes targeting Iran's capacity to threaten strait shipping, while Iran's Revolutionary Guard responded by attacking two oil supertankers and firing missiles and drones at American installations in Kuwait and Bahrain. President Trump compounded the uncertainty by announcing a reimposed blockade on Iranian ports and a transit fee for vessels seeking American naval protection — a declaration that the US would keep the waterway open by force if necessary.
The human cost of the standoff registers most plainly in shipping data. Only 57 vessels transited the strait over the three days from Friday to Sunday, compared to roughly 130 ships per day before the February strikes that first ignited the conflict. Captains and shipping companies are making a cold calculation: the risk of a war zone now outweighs the cost of waiting.
What worries analysts most is the disappearance of the safety nets. The Trump administration has leaned heavily on the US Strategic Petroleum Reserve to absorb supply shocks, but that stockpile is nearly depleted. Singapore-based analyst June Goh warned of a potential 'violent repricing' once the reserve runs dry, while Rory Johnston of Commodity Context noted that Hormuz traffic had fallen back to pre-peace-deal lows with the market's stock cushion now largely gone. Bart Melek of TD Securities put a number on the worst case: $100 a barrel, a nearly 20% jump from current levels that would send costs cascading through economies worldwide.
The Strait of Hormuz has long been one of civilization's most precarious chokepoints. Whether it becomes a pressure point that breaks depends now on whether military escalation continues or both sides find a reason to step back — with very little buffer remaining either way.
Brent crude climbed past $84 a barrel on Tuesday as the United States and Iran entered their third consecutive day of military strikes, reigniting fears about the world's most critical oil chokepoint. The price surge—a 2 percent jump that extended Monday's 9.6 percent gain—reflected a market suddenly uncertain about whether tankers would keep moving through the Strait of Hormuz, the narrow waterway between the Persian Gulf and the Arabian Sea through which roughly one-fifth of global oil passes.
The benchmark price reached $84.91 for September delivery by early Tuesday morning, the highest point since mid-June. The volatility erased months of stability that had followed a peace memorandum signed between Washington and Tehran just weeks earlier. Since the initial US-Israel strikes on Iran in late February, Brent has climbed roughly 17 percent, a reflection of the market's underlying anxiety about supply.
On Monday, US Central Command announced it had launched a third wave of strikes targeting Iran's capacity to threaten shipping and civilians in the strait. Iran's Islamic Revolutionary Guard Corps responded by attacking two oil supertankers in the waterway and firing missiles and drones at American military installations in Kuwait and Bahrain. The tit-for-tat escalation signaled that the brief window of relative calm had slammed shut. President Donald Trump added another layer of uncertainty by announcing that the United States would reimpose a blockade on Iranian ports and begin charging vessels a transit fee for American protection of the waterway.
The human cost of this standoff shows up most clearly in shipping traffic. Between Friday and Sunday, only 57 vessels transited the strait—a drop of more than 50 percent compared with the previous week. Before the February strikes, roughly 130 ships moved through daily. The paralysis reflects a simple calculation: captains and shipping companies are weighing the cost of fuel against the risk of being caught in a war zone. Many are choosing to wait.
Analysts watching the market see a dangerous erosion of the buffers that have kept prices from spiking further. The Trump administration has been drawing heavily on the US Strategic Petroleum Reserve—the government's emergency stockpile—to dampen supply shocks and reassure markets. But that cushion is nearly depleted. June Goh, a senior oil analyst at Sparta Commodities in Singapore, warned that crude could experience a "violent repricing" upward once the reserve runs dry and traders lose confidence that supply disruptions can be managed. Rory Johnston, founder of the oil research firm Commodity Context, echoed the concern, noting that traffic through Hormuz had fallen back to or below the levels seen immediately before the peace deal, and that the market's "ample stock cushion" was now largely gone.
The Department of Energy insisted on Monday that 8.5 million barrels had flowed through the strait the previous day with military escort, describing the volume as consistent with recent averages. The message was clear: the US military would keep the waterway open whether Iran cooperated or not. But traders are skeptical. Bart Melek, global head of commodity strategy at TD Securities in Toronto, predicted that oil could reach $100 a barrel if physical shortages become real and the risk of further disruption grows. That would represent a jump of nearly 20 percent from current levels—a shock that would ripple through economies worldwide, raising costs for everything from gasoline to shipping to heating fuel.
What happens next depends on whether the military escalation continues or de-escalates. If rhetoric cools and both sides step back, the market may stabilize. If the strikes continue and shipping traffic remains paralyzed, the depletion of the strategic reserve means there is little left to cushion the blow. The Strait of Hormuz, already one of the world's most fragile chokepoints, has become a pressure gauge for global economic stability.

Crude oil is fast losing its strategic petroleum reserve buffer, and a violent repricing up cannot be discounted until the market sees toned-down rhetoric from both parties— June Goh, senior oil market analyst at Sparta Commodities
I suspect that a move to $100 is quite possible, should it become apparent that physical shortage risks are real and increasingly likely— Bart Melek, global head of commodity strategy at TD Securities
La Conversación del Hearth Otra perspectiva de la historia
Why does fighting between two countries thousands of miles away affect what I pay at the pump?
Because roughly 20 percent of the world's oil passes through a single narrow waterway between Iran and Oman. When that waterway becomes dangerous, ships stop going through it. Less oil reaches markets. Prices rise.
But the US says it's keeping the strait open. Doesn't that solve the problem?
Technically, yes—8.5 million barrels moved through with military protection on Monday. But captains and shipping companies don't trust that protection to last. They're watching the rhetoric, watching the strikes, and deciding it's safer to wait. Fifty-seven ships in three days instead of 390. That's the real constraint.
What's the strategic reserve, and why does it matter so much?
It's the government's emergency stockpile of oil, built for moments exactly like this. The Trump administration has been selling from it to keep prices down and reassure markets that supply won't dry up. But they've nearly emptied it. Once it's gone, there's no buffer left.
So prices could hit $100?
One analyst thinks so, if shipping stays paralyzed and shortages become real. We're at $84.91 now. A jump to $100 would be significant—it would affect everything from airline tickets to food prices to heating bills.
What would make this stop?
If both sides stop attacking each other and shipping resumes, prices would likely fall. If the fighting continues and the reserve stays empty, prices could keep climbing. Right now, the market is waiting to see which way this goes.
