Crude opened the week with a jolt. West Texas Intermediate (WTI, the US benchmark crude grade) rose $2.17, or 2.48%, to $89.53 a barrel by 2312 GMT on Sunday, while Brent climbed $1.93, or 2.12%, to $93.05, after Israel ordered troops to push further into Lebanon against the Iranian-backed Hezbollah militant group, despite a ceasefire announced more than six weeks earlier.
The Lebanon push is the headline that moved the screens. It is not the thing holding the floor under the price. That job belongs to a 21-mile stretch of water at the mouth of the Gulf, where Iran has laid fresh sea mines and where roughly a fifth of the world’s oil keeps waiting for a safe channel out.
Lebanon Lit the Match Under Crude
Monday’s move followed a Friday in which both benchmarks already settled higher, Brent up 1.8% and WTI up 1.7%, on hopes that Washington could broker an extension to the US-Iran ceasefire. The renewed fighting in Lebanon cut against that optimism within 48 hours, and traders repriced the risk that the broader conflict is far from over.
The Israel-Lebanon front has been the widest spillover of the Iran war. It opened on March 2, when Hezbollah began firing rockets and drones across the border into Israel to back its ally in Tehran. The two sides reached a ceasefire in mid-April, then kept trading fire across the line for weeks.
Here is the snapshot that markets woke up to:
- $89.53 WTI, up $2.17 (2.48%) in early Monday trade
- $93.05 Brent, up $1.93 (2.12%) over the same window
- Friday close: Brent +1.8%, WTI +1.7% on ceasefire-extension hopes
The Chokepoint Holding the Price Floor
Strip out the Lebanon noise and the supply math is what keeps buyers paying up. The Strait of Hormuz is the single most important valve in the oil trade, and Iran has effectively shut it since the conflict began with US and Israeli strikes in February. In a normal year that valve carries around 20 million barrels a day, about one-fifth of global petroleum liquids consumption, according to the EIA’s tally of Strait of Hormuz oil traffic.
The US Energy Information Administration (EIA, the statistical arm of the Department of Energy) has already logged the damage. Gulf producers including Saudi Arabia, the UAE, Kuwait, Iraq, Qatar and Bahrain collectively shut in 7.5 million barrels a day in March, a figure the agency projected would climb to 9.1 million in April before easing.
That is the part the Lebanon story tends to bury. A militia firing rockets across a land border is dramatic, but it does not by itself remove barrels from the seaborne market. A mined chokepoint does, and it does so on a scale that dwarfs the day’s headline. The price is not reacting to one battlefield; it is reacting to a closed artery.
Our earlier coverage tracked how quickly that artery became the market’s obsession, with Brent’s run past $111 a barrel on Strait of Hormuz supply fears showing how little it takes to send the curve higher once traders focus on the strait.
Why a Ceasefire Won’t Flood the Market
The trap for anyone betting on a sharp pullback is the assumption that a deal flips the supply switch back on. It does not. Mines have to be found, identified and neutralized before tankers and their insurers will commit to the route, and that clearing work is slow, dangerous and easy to disrupt.
Even if an agreement is reached, it won’t deliver a flood of supply.
That warning came from Tony Sycamore, a market analyst at brokerage IG, who flagged in a client note that fresh mines in the strait could slow any reopening and delay relief for the oil market even after the shooting stops. The clearing timelines back him up: a RAND analysis of demining the strait notes that mine countermeasures assets move slowly and largely lack self-defense, while estimates presented to Congress have stretched to six months for a full sweep. You can read the operational detail in a RAND briefing on clearing mines in the Strait of Hormuz.
The Deal Trump Is Still Weighing
On Friday, US President Donald Trump said he would soon decide on a proposed deal to extend the early-April ceasefire with Iran, buying negotiators more time for a permanent settlement and a fix for the underlying dispute over Iran’s nuclear program. Israel would be central to any agreement, and Tehran has insisted Hezbollah be included.
The mine question is now a ceasefire question. An Axios reporter said on X on Friday that Iran had dropped more mines in the strait earlier in the week, shortly after US Defense Secretary Pete Hegseth warned that laying more mines would be a violation of the truce.
Here is how the conflict reached this point:
- February: US and Israeli strikes hit Iran; Tehran effectively closes the strait to traffic.
- March 2: Hezbollah opens the Lebanon front with rockets and drones into Israel.
- Mid-April: Israel and Lebanon reach a ceasefire, then keep trading fire.
- Friday: Washington hosts Israel-Lebanon peace talks; Trump signals a decision on extending the Iran truce.
- Sunday: Israel orders troops deeper into Lebanon, and crude gaps higher.
Markets had leaned the other way only days earlier. When the diplomatic track looked alive, prices sagged, a swing our desk captured as Brent fell more than six percent on Iran peace-talk optimism. The Lebanon order reversed that mood in a single session.
Importers Pay the Premium First
A sustained supply premium does not land evenly. The countries that buy crude rather than pump it feel it first, through pricier fuel imports, weaker currencies and fatter import bills. The pain map looks like this:
- Asian crude importers that draw heavily on Gulf barrels, where a closed strait forces longer, costlier voyages around it.
- Currency-exposed economies such as India, where a rising oil bill drains reserves and pressures the rupee.
- Refiners and airlines facing higher feedstock and jet-fuel costs they cannot fully pass on.
India shows the mechanism in real time. The rupee has buckled under the oil shock, a slide our markets team detailed when the rupee opened at a record 96.38 to the dollar on the oil shock. Every dollar added to Brent widens the gap between what import-reliant economies budgeted and what they now have to spend.
There is one counterweight, and it sits in the demand column. Weekend data from China showed factory activity stalling, with exports contracting and cost pressures building, a sign the world’s second-largest economy is losing momentum. Softer Chinese demand normally caps oil. This week, supply fear simply outran it.
Where Brent Goes From $93
The forward path now hinges on two clocks running at different speeds: the diplomatic clock, which could deliver a ceasefire in days, and the engineering clock, which needs months to make the strait passable again. The EIA’s own numbers assume the gap between them keeps prices elevated well into the year before they fade.
| Period | EIA Brent outlook | What drives it |
|---|---|---|
| March 2026 (actual) | $103 average | Strait closure, Gulf shut-ins begin |
| Q2 2026 (peak) | $115 | Shut-ins near 9.1 million b/d |
| Q4 2026 | Below $90 | Production slowly returns |
| 2027 (average) | $76 | Output near pre-conflict levels |
The agency’s read, set out in the EIA’s short-term price outlook on the Hormuz closure, is that crude peaks in the second quarter near $115 a barrel, then eases as shut-ins abate, slipping below $90 by the fourth quarter and averaging $76 in 2027. Administrator Tristan Abbey stressed the forecast is highly contingent on three moving parts: how long the strait stays shut, how fast production recovers, and how quickly the reopening, which he said will take months, actually proceeds.
At $93, Brent sits between those two clocks. If the ceasefire holds and the mine-clearing begins on schedule, the premium drains through the back half of the year and importers get their relief. If the mines stay in the water or the Lebanon front widens again, the strait stays shut in practice, and the EIA’s $115 peak starts to look like a floor rather than a ceiling.
Frequently Asked Questions
Why are oil prices rising this week?
Prices rose more than 2% after Israel ordered troops to move further into Lebanon against Hezbollah, despite a six-week-old ceasefire. WTI gained 2.48% to $89.53 and Brent 2.12% to $93.05. The escalation dimmed hopes for an extension of the US-Iran ceasefire and revived supply fears tied to the closed Strait of Hormuz.
How much oil passes through the Strait of Hormuz?
In a normal year the strait carries around 20 million barrels a day, roughly one-fifth of global petroleum liquids consumption, according to the EIA. Iran has effectively closed it since US and Israeli strikes in February, and Gulf producers shut in 7.5 million barrels a day in March, a figure projected to rise toward 9.1 million in April.
Will a ceasefire bring oil prices back down quickly?
Not immediately. Analysts warn that fresh sea mines must be cleared before tankers and insurers return, and that clearing work is slow. Estimates range from a few weeks to six months for a full sweep, so a diplomatic deal would not deliver an instant flood of supply.
Where does the EIA expect Brent to go?
The EIA expects Brent to peak in the second quarter of 2026 near $115 a barrel, then ease as production shut-ins recover, falling below $90 in the fourth quarter and averaging $76 in 2027. The forecast depends on how long the strait stays shut and how fast it reopens.
