Oil Prices Surge Over 2.5% as US-Iran Strikes Renew Supply Fears

Oil prices jumped more than 2.5% on Monday, with Brent crude rising above $90 a barrel, following renewed military strikes between the US and Iran near the Strait of Hormuz. The escalation, including Iranian missile attacks on US air bases in Jordan and a US strike on an Iranian island, revived concerns about energy supply disruptions. Meanwhile, Brent continued to climb on Tuesday, exceeding $91.

Oil Prices Jump on Renewed US-Iran Clashes

Oil prices closed more than 2.5% higher on Monday, with Brent crude futures rising $2.39, or 2.71%, to $90.49 a barrel, while US West Texas Intermediate (WTI) gained $2.36, or 2.83%, to $85.76 a barrel. During the session, Brent climbed as high as $91.52, its highest level since August 25, according to Proto Thema.

The latest surge followed an exchange of military strikes between Washington and Tehran. US President Donald Trump was reportedly preparing a tough response after Iranian missiles were launched at two US air bases in Jordan. Tehran's attack came in retaliation for a US strike on Iran's Larak Island, as reported by Proto Thema.

Trump was quoted by Fox News as saying, "We will hit them hard. There will be a response," according to Proto Thema. The remarks raised fears of further escalation, as did Trump's earlier characterization of the conflict as a "little war," which he used to play down suggestions that US military resources were being strained, reported CNBC TV18.

The fighting marked the first direct military exchange between the US and Iran in roughly a month, stoking fears of extended disruption to energy shipments through the Strait of Hormuz, a critical chokepoint for global oil supplies, according to CNBC TV18.

Strait of Hormuz in Focus

The renewed clashes brought the Strait of Hormuz back to the center of market attention. Before the war began in late February, roughly one-fifth of global oil supplies passed through the strait, noted Proto Thema. Shipping data showed that the number of visible cargo vessels crossing the strait over the weekend fell to five per day, the same source reported.

Despite the danger, oil exports have continued to move through the strait, with many tankers switching off their transponders to avoid being tracked, CNBC TV18 reported. Gulf producers including the UAE, Saudi Arabia, Kuwait, and Iraq were all still managing to move barrels out of the region, the outlet added. Analysts at Gelber & Associates noted that some volumes of Gulf oil are still passing through the strait, limiting the extent of the price increase, according to Proto Thema.

The UK Maritime Trade Operations (UKMTO) reported that a tanker leaving the Strait of Hormuz near Oman was hit by three unidentified projectiles while under way, CNBC TV18 said.

Conflict Escalation and Market Reactions

Iran aimed missiles at US air bases in Jordan, with local reports saying air defences intercepted and destroyed eight of the projectiles before they could cause damage, according to CNBC TV18. The strikes on the UAE and Jordan were the first such exchange in about a month, the outlet added.

On Sunday, Trump said in a social media post that Iran's energy hub on Kharg Island was "being blown to pieces," although there was no evidence confirming that the island was under attack, Proto Thema reported. The post was accompanied by an AI-generated video and contained no further details. Iran denied that Kharg was under attack, saying oil operations on the island were continuing normally, the same source said. US Vice President D. Vance said that Trump was sending a message to Tehran through the post, according to Proto Thema.

Investors are now focused on whether the latest military tensions can ease or whether the recent attacks signal the beginning of a new cycle of conflict, Proto Thema reported. The first direct military exchange in a month forced traders to once again price in a significant short-term supply risk premium, the outlet added.

Refined Products and Supply Side

The West Asia conflict, compounded by the ongoing war between Russia and Ukraine, pushed refined-product prices up even faster than crude prices as supplies tightened, with diesel among the worst hit, CNBC TV18 reported.

On the supply side, crude inventories in the US Strategic Petroleum Reserve (SPR) fell by around 3.1 million barrels last week to 286.6 million barrels, according to Proto Thema. Additionally, the Abu Dhabi National Oil Company (ADNOC) brought its Ruwais refinery back to full output after war-related damage earlier in the conflict, as reported by CNBC TV18, citing a Bloomberg report.

US Treasury Secretary Scott Bessent told CNBC on Monday that the goal of US sanctions against Iran is "to create the conditions so that they will come back to the table" for negotiations, Proto Thema reported.

Oil Prices Continue Climbing Tuesday

Oil prices climbed for a second straight session on Tuesday, September 1, with Brent crude rising above $91 a barrel, while WTI held above $86 after jumping 2.8% on Monday, its sharpest one-day rise in three weeks, CNBC TV18 reported. Markets moved as renewed fighting between the US and Iran continued to stoke fears of extended disruption to energy shipments through the Strait of Hormuz, the outlet said.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
