Oil surges 2% as US-Iran strikes reignite Strait of Hormuz disruption fears
Five ships a day through the world's oil artery
Mark
Why does what happens in the Strait of Hormuz matter so much to oil prices?
Mimi
Because a fifth of the world's oil flows through it. It's a chokepoint. If shipping stops or slows, the supply signal hits markets immediately.
Luke
But the strait hasn't actually closed, right? Five ships a day is low, but it's not zero.
Mimi
True. It's the fear of closure that's moving prices, not closure itself. And the fear is rational—there's an active conflict happening there.
Mark
So when Trump posted about Kharg Island being destroyed, why didn't that spike prices more?
Luke
Because Iran denied it, and there was no evidence. The market didn't believe the claim. An AI video with no details isn't credible.
Mimi
Exactly. If the island actually went down, that would be a supply shock. But nobody can verify it happened, so traders treated it as noise.
Mark
What would actually cause a bigger price move?
Mimi
An actual closure of the strait, or a sustained attack on tankers that makes insurance prohibitively expensive.
Luke
Or a breakthrough in negotiations that reopens it. That would probably push prices down.
Mark
How long can this stalemate last?
Mimi
Analysts are guessing oil stays in the $85-95 range until something gives. But six months in, there's no sign of movement.
Luke
And the U.S. is planning weekly sanctions, which suggests they're not expecting a deal soon either.
The Pulse
- U.S. strikes on Iran's Larak Island and Iranian retaliatory attacks on American bases in Jordan marked the sharpest military exchange in weeks, jolting energy markets out of a fragile calm.
- Vessel traffic through the Strait of Hormuz collapsed to just five ships per day over the weekend, and a tanker struck by a projectile on Saturday made clear the danger is neither distant nor abstract.
- President Trump's social media claim that Iran's Kharg Island was being destroyed was flatly denied by Tehran, deepening the fog of conflicting narratives that now surrounds every development in this conflict.
- Negotiations to reopen the strait remain deadlocked after six months, and analysts who had hoped for progress by quarter's end are quietly revising that timeline further into the future.
- Brent crude settled near $89.87 and WTI near $84.85, with analysts forecasting a holding pattern between $85 and $95 per barrel until the strait's status becomes clearer.
- Washington is tightening economic pressure in parallel, with weekly Iran sanctions planned and Venezuelan oil earmarked to replenish a U.S. Strategic Petroleum Reserve near a 44-year low.
For six months, the Strait of Hormuz — the narrow throat through which a fifth of the world's oil passes — has been slowly closing, and this weekend's exchange of strikes between the United States and Iran tightened that constriction further. Oil prices rose nearly two percent as markets absorbed what has become a familiar rhythm: military action, retaliation, and the receding prospect of a return to normalcy in one of civilization's most consequential waterways. The conflict is not yet catastrophic, but it is persistent, and persistence has its own kind of cost — measured now in cautious captains, stalled negotiations, and crude trading in a range that reflects a world holding its breath.
Oil prices climbed nearly two percent on Monday after the United States and Iran exchanged strikes over the weekend, reviving fears of prolonged disruption to the Strait of Hormuz — the narrow passage through which a fifth of global oil supply travels. Brent crude rose to $89.87 a barrel and WTI to $84.85, as traders absorbed the latest flare-up in a conflict now entering its sixth month.
The immediate trigger was a U.S. strike on Iranian launcher systems on Larak Island, the first known American military action against Iran since late July. Tehran responded by attacking two U.S. air bases in Jordan. The cycle has grown familiar enough that it no longer shocks markets — but it moves them, because every escalation pushes back the possibility of the strait returning to normal commercial traffic.
President Trump's weekend social media post claiming Iran's Kharg Island energy hub was being destroyed — accompanied by an AI-generated video — added a layer of confusion. Iran denied any attack on the island and said oil operations there continued uninterrupted. The gap between claim and evidence has become a defining feature of this conflict.
Shipping data captured the real-world effect: only five commodity vessels transited the strait daily over the weekend, and a tanker was struck by a projectile on Saturday. Before the conflict began in late February, the strait was a routine commercial corridor. Now it is a passage where risk is calculated voyage by voyage.
Mediation efforts remain stalled, and analysts who had anticipated some diplomatic movement by quarter's end are now less optimistic. DBS energy research head Suvro Sarkar described the likely trajectory as "contained confrontation" — serious enough to keep prices elevated, but short of the kind of sustained escalation that would break the current range. Oil is expected to trade between $85 and $95 per barrel until the strait situation clarifies.
On the economic front, Treasury Secretary Scott Bessent said the administration plans to issue new secondary sanctions against Iran weekly. Separately, Trump announced that oil from a recently negotiated deal with Venezuela will replenish the U.S. Strategic Petroleum Reserve, which has fallen to near its lowest level in 44 years. The market, for now, is waiting — for a diplomatic opening, a shift in the conflict, or something that breaks the stalemate.
Oil prices climbed nearly 2% on Monday as the United States and Iran exchanged strikes over the weekend, reigniting fears that the Strait of Hormuz—the narrow waterway through which a fifth of the world's oil flows—could face prolonged disruption. Brent crude futures rose $1.77 to $89.87 a barrel, while West Texas Intermediate crude gained $1.45 to $84.85, as traders absorbed the latest escalation in a conflict now stretching into its sixth month.
The trigger was straightforward: U.S. forces struck two launcher systems on Iran's Larak Island in the strait on Sunday, marking the first known American military action against Iran since late July. Tehran responded by attacking two U.S. air bases in Jordan, according to Iranian media citing the country's Revolutionary Guards. The cycle of retaliation has become familiar enough that it no longer shocks markets—but it does move them, because every flare-up pushes back the possibility of the strait reopening to normal traffic.
President Trump posted on social media Sunday claiming that Iran's Kharg Island energy hub was being "blown to smithereens," accompanied by an AI-generated video clip. The post offered no supporting detail, and Iran flatly denied any attack on the island, asserting that oil operations there continued uninterrupted. The discrepancy between Trump's claim and the available evidence underscored the fog that now surrounds this conflict—what is actually happening versus what is being claimed about what is happening.
The real measure of disruption lies in the strait itself. Shipping data showed that only five commodity vessels transited the waterway daily over the weekend, a sharp drop reflecting the caution of companies wary of becoming targets. The United Kingdom Maritime Trade Operations reported that a tanker was struck by a projectile while sailing inbound through the strait on Saturday, a reminder that the risk is not theoretical. Before the conflict began in late February, the strait was a normal commercial highway. Now it is a corridor where captains calculate odds.
Negotiations aimed at ending the broader conflict remain deadlocked, and mediators working to reopen the strait have made little visible progress. Suvro Sarkar, head of energy research at DBS, offered a measured assessment: the market should expect "contained confrontation rather than any sustained escalation," but each new incident delays the timeline for reopening. Analysts had hoped negotiations might resume by the end of the third quarter, but that prospect now looks unlikely. The result is a holding pattern—oil prices likely to trade between $85 and $95 per barrel unless the situation in the strait clarifies.
Meanwhile, the U.S. Treasury Secretary Scott Bessent signaled that Washington intends to tighten the economic vise, telling Reuters the administration plans to issue new secondary sanctions against Iran on a weekly basis. On another front, Trump announced that oil from a recently negotiated deal with Venezuela will be used to replenish the U.S. Strategic Petroleum Reserve, which has fallen to near its lowest level in 44 years. Brent and WTI are on track to post small declines for August overall, though both fell more than 4% last week in their first weekly drop in three weeks. The market is waiting—for clarity on the strait, for a shift in the conflict, for something to break the current stalemate.

We see more chances of contained confrontation rather than any sustained escalation in the conflict. What continues to be impacted with every flare up are the timelines for Hormuz reopening.— Suvro Sarkar, head of energy research at DBS
