Oil prices rose more than 2% after the United States struck two Iranian launchers on Larak Island in the Strait of Hormuz, turning a military action aimed at protecting shipping into a fresh test of the global energy market’s ability to absorb another escalation. Brent crude moved above $90 a barrel, while West Texas Intermediate also climbed sharply, as traders reacted not simply to the strike itself but to the possibility that Iran could retaliate in ways that further restrict traffic through one of the world's most important energy routes.
The immediate market response was driven by the risk of disruption rather than evidence of an actual loss of global oil supply. The United States said its forces targeted launchers after observing Iranian forces preparing to use rockets carrying sea mines in the Strait of Hormuz. Iran subsequently reported retaliatory attacks against American military positions in Jordan. The exchange ended a period of relative calm and introduced a new uncertainty into an already fragile effort to restore normal shipping through the waterway.
That distinction matters because oil markets routinely price anticipated shortages before physical supplies disappear. When traders believe that a major shipping route could become less reliable, the price of crude can rise to reflect the additional risk carried by every cargo. The Larak strike therefore matters less because two launchers were destroyed than because it demonstrated how quickly military confrontation can return to the centre of the energy market.
Hormuz remains the market’s biggest vulnerability
The Strait of Hormuz is unusually important because the alternatives for moving Persian Gulf oil are limited. In the first half of 2025, about 20.9 million barrels per day of petroleum and other liquids passed through the strait, equivalent to roughly one-fifth of global petroleum liquids consumption and about one-quarter of maritime oil trade. Most of the crude and condensate moving through Hormuz was destined for Asian markets, particularly China, India, Japan and South Korea.
This concentration explains why relatively limited military activity can have an outsized effect on crude prices. Oil does not have to stop flowing completely for the market to become more expensive. Tankers may delay voyages, insurers may increase premiums, shipowners may demand higher returns for entering a dangerous area and traders may accumulate additional inventories. Each of those reactions raises the effective cost of moving energy even if barrels continue to reach consumers.
The latest shipping data indicate that this mechanism is already operating. The number of visible commodity vessels moving through the strait over the weekend fell sharply, while maritime authorities reported that a tanker had been struck by a projectile. The decline in traffic is important because it shows that the market is responding to perceived security risks before a complete physical blockade occurs.
That creates a difficult situation for policymakers. Washington is attempting to keep the waterway open while simultaneously applying military and economic pressure on Tehran. Iran, meanwhile, has demonstrated that it retains the ability to threaten maritime traffic even when it does not completely close the strait. The resulting uncertainty can keep an oil risk premium embedded in prices for much longer than the duration of an individual military exchange.
The Larak attack changes the escalation calculation
The significance of the American strike lies partly in what it targeted. Washington said the launchers were being prepared to deploy sea mines into the waterway, making the operation directly connected to maritime security rather than an attack on an Iranian oil facility. That provides the United States with a narrower stated justification for military action, but it also means that any Iranian response affecting shipping could produce another American reaction.
This creates a potentially self-reinforcing cycle. A perceived threat to commercial shipping prompts military action; military action prompts retaliation; retaliation increases the perceived risk to ships; and higher maritime risk pushes oil prices upward. The important question for markets is therefore not whether the Larak operation immediately removes barrels from the market. It is whether the exchange makes future disruptions more likely.
Recent experience has already shown how sensitive Hormuz flows are to changing security conditions. Oil flows recovered strongly during a temporary easing of hostilities earlier in the year, with Gulf exports rising as tankers moved through the strait more freely. But those flows remained below their pre-war levels, demonstrating that shipping confidence can return gradually even when physical infrastructure remains available.
The latest escalation threatens that recovery. Negotiations over reopening the strait remain uncertain, while the United States is also preparing additional financial pressure on Iran. Treasury Secretary Scott Bessent has indicated that Washington intends to continue imposing secondary sanctions, potentially tightening the economic pressure on countries and financial institutions dealing with Tehran. The combination of sanctions and military pressure makes the energy outlook more difficult to separate from the broader geopolitical confrontation.
Higher prices do not necessarily mean an oil shortage
The market's reaction also needs to be kept in perspective. Brent and WTI had recently fallen sharply, and both benchmarks were still positioned for monthly declines despite Monday's rebound. That suggests traders were not treating the Larak strike as proof of an immediate global supply crisis. Instead, prices were adjusting to a higher probability of disruption after a period in which expectations of greater flows had helped push crude lower.
There are also limited buffers outside the strait, although they cannot fully replace Hormuz. Saudi Arabia, the United Arab Emirates and Iran have pipeline routes that can bypass part of the waterway, but their combined alternative capacity is far below the volumes normally transported through Hormuz. This means that a prolonged closure or severe restriction would be difficult to offset through existing infrastructure alone.
The United States has another potential cushion in its Strategic Petroleum Reserve, but its position is less comfortable than it once was. President Donald Trump has announced that oil obtained under a new agreement with Venezuela will be used to replenish the reserve, which currently holds roughly 290 million barrels, close to a 44-year low. However, additional Venezuelan production would require investment and infrastructure improvements, meaning that the agreement cannot be treated as an immediate solution to a sudden Hormuz disruption.
For Asian economies, the exposure is more direct. China, India, Japan and South Korea together accounted for a large majority of the crude and condensate moving through Hormuz in the first half of 2025. A prolonged disruption would therefore transmit higher shipping and crude costs into economies that rely heavily on imported energy. The effect would extend beyond petrol and diesel to transport, manufacturing, chemicals, power generation and other industries that use petroleum products.
Oil’s next move depends on shipping, not headlines
The central market signal from the Larak strike is that traders are watching the physical condition of the Strait of Hormuz more closely than the headline military exchange alone. If shipping resumes and tankers continue moving in meaningful numbers, the initial price increase could fade as the market concludes that the confrontation remains contained. If vessels continue avoiding the route, insurers raise costs and military incidents multiply, the risk premium could become considerably more persistent.
That makes the coming response from both sides more important than the initial strike. Iran's retaliatory action against American positions in Jordan has already widened the geographical scope of the confrontation. At the same time, the United States has made clear that it intends to protect maritime traffic, while Tehran has repeatedly demonstrated that control over access to Hormuz remains one of its most powerful strategic instruments.
Oil markets are consequently facing two competing forces. Supply flows have shown some ability to recover when security conditions improve, limiting the need for an immediate surge in prices. But the physical vulnerability of Hormuz remains exceptionally high, and every new military incident increases the cost of assuming that normal shipping can continue.
The rise above $90 therefore represents more than a reaction to one strike. It reflects the market placing a renewed premium on the possibility that the world's most important oil chokepoint could again become the centre of the conflict. Whether that premium persists will depend on whether Larak proves to be an isolated military episode or the beginning of another cycle of attacks, retaliation and disruption across the waterway.
