Brent crude settled at $104.21 on Monday, up $2.92 on Trump's verbal alone. Saudi Aramco chief executive Amin Nasser said the market is losing roughly 100 million barrels of supply each week, with prolonged disruption pushing any normalisation into 2027.

Key takeaway

Brent at $104 prices Trump's words; Aramco's 100 million barrels per week implies a 17.5% unpriced shock.

Brent Crude settled at $104.21 on Monday 11 May, up $2.92 (2.9%) on $101.29 the previous session 1. The move broke the $101 floor that had held through Friday's bulk-carrier strike near Doha, the Mokhber doctrine declaration and the IRGC firing-order threat . Nothing signed underwrote the spike: it came on Donald Trump's Oval Office verbal statement, with no executive order, deployment directive or CENTCOM operational order behind it. Brent traded above $94 on Tuesday morning, holding most of Monday's gain.

Saudi Aramco chief executive Amin Nasser said the same day that the market is losing roughly 100 million barrels of supply each week and that prolonged disruption could push any normalisation into 2027 2. That weekly loss roughly equals Saudi Arabia's full weekly output. Translated into a daily run rate against the notional 80 million barrels per day global crude base, Nasser's number implies a 17.5% supply shock against a curve that has not priced it.

Brent at $104.21 prices the market's probability-weighted average of paper outcomes, not Nasser's physical-market reading; priced literally, Nasser's number justifies materially higher Brent. The ceiling holds while Wall Street still expects a deal; it breaks upward if Trump signs a bombing order on his Friday return, or downward if he signs a written counter-text. For UK consumers the lag template is already running: the $4.54 per US gallon pump benchmark hit on 8 May is the precedent forecourts will follow within a fortnight, putting roughly £1.78 per litre on UK pumps before the Beijing trip closes.

Deep Analysis

In plain English

The price of oil went up sharply on 11 May after Trump's tough statements about Iran. It reached $104.21 per barrel, breaking through a floor of about $101 that had held for several days. The CEO of Saudi Aramco; the world's largest oil company; said the world is losing around 100 million barrels of oil supply every week because of the Hormuz disruption. He warned it could be 2027 before the situation returns to normal. For ordinary people, this means petrol and diesel prices could rise further over the coming weeks if the situation does not improve. Oil prices that stay above $100 for an extended period push up the cost of transport, heating, and most goods that need to be shipped.

Deep Analysis
Root Causes

The Strait of Hormuz carries approximately 21 million barrels of oil per day in normal conditions; roughly a quarter of global seaborne crude. Iran's Persian Gulf Strait Authority has imposed a toll and registration requirement that most Western-flagged carriers have not complied with, effectively reducing transit to a fraction of pre-war volumes.

Saudi Aramco's export routes do not depend on Hormuz for the majority of its exports via the East-West pipeline to Yanbu on the Red Sea, but Aramco ships roughly 7 million barrels per day that do transit the strait; giving Nasser's 'market is losing supply' framing a direct commercial basis, not merely geopolitical observation.

The oil market's difficulty pricing the disruption reflects genuine uncertainty about whether a deal materialises this week or in three months: two scenarios produce $75 and $120 Brent respectively, so the $104 settlement is arithmetically the probability-weighted midpoint.

What could happen next?
  • Consequence

    Sustained Brent above $100 triggers fuel surcharge reviews at major freight carriers. US, UK, and EU logistics cost indices will absorb the move within 30 days.

  • Risk

    A 2027 normalisation scenario; if Nasser's guidance is treated as credible; would prompt hull and cargo insurers to reprice annual premiums at Q3 2026 renewal cycles, adding $15-25 per barrel in effective delivered cost for Asian buyers.

    Medium term · 0.6
  • Opportunity

    The $101 floor breaking higher gives US negotiators a price signal they can present to Iran: a deal that reopens Hormuz produces immediate Brent compression to $85-90, saving Tehran from the inflationary oil-price feedback on its own import costs.

Different Perspectives
Gulf shipping and insurance markets
Gulf shipping and insurance markets
With Hormuz and Bab el-Mandeb both hostile at once, war-risk underwriters face their first dual-chokepoint pricing problem; the rerouting hedge that absorbed one closure is gone for Israeli-linked hulls. Any deal that reopens Hormuz without a Houthi stand-down clause delivers only partial shipping relief.
Russia and China
Russia and China
Russia and China met IAEA chief Grossi jointly in Geneva on 5 June to coordinate an advance blocking position against Washington's censure resolution, the first documented instance of proactive pre-session obstruction rather than reactive post-vote dissent. Beijing's move came four days after OFAC designated Shanghai Qianye Energy under Iran energy sanctions.
Saudi Arabia
Saudi Arabia
Saudi Arabia was left out of the emergency $4.01 billion Patriot waiver Qatar received on 2 May as its own PAC-3 stocks ran near-empty from intercepting Iranian salvoes over Aramco facilities. Riyadh is on a standard 18-month FMS queue behind a production line booked through 2030, with no equivalent priority to Qatar's Al Udeid basing role.
Houthis (Ansar Allah)
Houthis (Ansar Allah)
The Houthis declared a complete ban on Israeli Red Sea navigation on 8 June and struck Jaffa, their first attack on Israeli territory since April, seven days after the Tasnim authorisation to activate other fronts including Bab el-Mandeb. The declaration put both chokepoints under hostile authority simultaneously.
Iran
Iran
Iran agreed the 9 June mutual halt after the Mahshahr exchange and coordinated with Russia and China to block Washington's IAEA censure resolution, using the Board as a second front while the bilateral pause held on the military one. Tehran's acceptance of the Lebanon carve-out contradicts the linkage position it stated on 1 June.

Benjamin Netanyahu and the IDF
Israel struck the Karun Petrochemical plant at Mahshahr on 8 June over Trump's explicit objection, then agreed a halt with Iran the following day scoped on Israeli terms with Lebanon carved out. Netanyahu's posture is that the IDF will not accept Iranian missile factories as off-limits regardless of US diplomatic timelines.
