Key takeaway

Goldman Sachs's $120 severe scenario is now the operative frame, not the tail risk.

Brent Crude surged 8% above $103 on the blockade announcement, reversing the post-ceasefire drop that had taken prices to $92.21. Goldman Sachs had cut its Q2 Brent forecast to $90 after the ceasefire was announced. The blockade made that forecast obsolete within a day. Goldman's severe scenario, $120 by Q3, is now the operative frame rather than the tail risk.

Approximately a dozen Iranian supertankers carrying an estimated $2.4 billion of crude sit stationary in The Gulf of Oman, caught between CENTCOM's blockade from one side and Iran's own mine and vetting regime from the other. The $2.4 billion figure derives from operational analysis rather than wire-service confirmation. 325 tankers remain stranded in The Gulf. Hormuz traffic, which had climbed to 17 transits by Saturday, dropped to near zero when enforcement started⁠¹. 20,000 sailors aboard roughly 2,000 vessels are stranded.

Saudi Arabia has insulated itself: its Petroline pipeline, restored to full capacity, now routes all exports via the Red Sea, bypassing Hormuz. That protects Riyadh's revenue but does nothing for the 21 million bpd that normally transits the strait .

Deep Analysis

In plain English

Oil prices shot up sharply on Monday when the blockade was announced. Brent Crude , the international benchmark for oil pricing , jumped 8% above $103 per barrel. For context, it had fallen to $92 after the ceasefire last week. Why does this matter to you? Oil prices feed into fuel prices at petrol stations, heating costs, and the cost of transporting goods. When oil goes up, almost everything gets slightly more expensive with a delay of a few weeks. Goldman Sachs, one of the world's largest banks, had previously predicted oil could reach $120 in the worst case. Before Monday, that seemed unlikely. Now analysts say it is possible without anything further going wrong.

What could happen next?

Consequence
April CPI will layer blockade-driven fuel costs on top of March's 0.9% monthly rise , the largest since 1967 , creating a two-month compounding effect that central banks cannot offset without rate rises that would further damage consumer confidence.
Short term · 0.85
Risk
If Goldman's $120 scenario materialises, US Federal Reserve rate policy is constrained: cutting rates to support the economy while inflation is energy-driven would be politically untenable, forcing a stagflationary choice between growth and price stability.
Medium term · 0.72
Opportunity
Saudi Arabia, now exporting via Petroline and insulated from Hormuz disruption, benefits from elevated prices without the supply constraint , strengthening Riyadh's fiscal position and reducing its incentive to mediate a Hormuz resolution.

Source Landscape

This story draws on neutral-leaning sources from United States (includes United States state media)

United States

Primary parallel: The 1973 Arab Oil Embargo sent Brent's predecessor from $3 to $12 in under three months , a 300% rise , by restricting supply to specific countries. The 2026 shock mechanism is different: not country-targeted embargo but physical chokepoint closure.

The closer structural parallel is the 1967 Suez Canal closure, which added 5,000 miles to tanker routes and created a sustained 18-month freight premium rather than a sharp price spike. The Hormuz closure is structurally more severe than Suez because there is no bypass route for most Gulf producers.

Counter-parallel: The 2019 Abqaiq drone strikes on Saudi Arabia's largest crude processing facility briefly cut global supply by 5 million bpd and sent Brent up 15% in a single session , but prices recovered to pre-strike levels within 10 days as Saudi Aramco restored capacity. The 2026 disruption has no equivalent restoration mechanism: the Hormuz Chokepoint is not a facility that can be repaired.

The $103 level represents the second structural repricing in 45 days. The first came at war's outbreak (from $82 to $95); the post-ceasefire correction fell to $92.21; Monday's blockade announcement recovered and exceeded the war-onset high.

At $103 Brent, the transmission to consumer prices is: UK average petrol prices rise approximately 2-3 pence per litre per $10 Brent move, with a 10-14 day lag. A sustained $103-110 range would add 2-4p per litre within a fortnight. Diesel, which powers UK goods transport, tracks more closely and faster.

The 325 stranded tankers represent an inventory overhang: when the blockade eventually resolves, that trapped crude will reach markets simultaneously, potentially creating a brief price collapse before the supply structure normalises. Goldman's $120 scenario assumes the blockade sustains through Q3; if it breaks in May, spot prices could fall sharply even as structural damage to tanker routing persists.

Consensus view: Goldman Sachs commodities research (head of global commodities Daan Struyven) and Citigroup's Ed Morse both assess the $103 level as the market's recalibration from 'stalemate' to 'active blockade' pricing.

The $8 single-session move is consistent with the range Goldman assigned to a blockade scenario in its 9 April note, which set $120 as the Q3 severe case. Before the blockade, that was a tail-risk scenario. Now, as Struyven noted, it requires no further escalation to reach.

Counter-view: The Oxford Institute for Energy Studies (OIES) argues that $120 is not a base case regardless of the blockade, because Saudi Arabia's Petroline restoration to 7 million bpd context; Petroline event in skeleton and UAE's ADCO pipeline capacity provide a partial Hormuz bypass. OIES's Bassam Fattouh calculates that non-Hormuz-dependent Gulf export capacity sits at roughly 9 million bpd , enough to satisfy most of Europe's needs but leaving Asia-Pacific exposed.

Key tension: Whether the oil market is pricing a supply shock (shortage of physical barrels) or a risk premium (uncertainty about supply even if some barrels reach market) , the two require different policy responses and have different price-duration profiles.

Different Perspectives

United States (Joint Maritime Information Center)

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.

Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

Korea Shipowners' Association

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.

Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
