Key takeaway

Brent closed 45 per cent above the pre-war baseline after a 21 April round trip through the $100 handle.

Brent Crude briefly crossed $100 per barrel on expiry morning on 21 April before retreating to $97.91 by close after Trump's extension post landed ¹. The close sits 45 per cent above the $67.41 pre-war baseline. Goldman Sachs's $120 Q3 severe scenario remains the operative forecast frame across sell-side desks.

Monday's 7 per cent surge to $96.88 on early extension hope gave Tuesday's market the exit-trigger test, and the trigger was identified as unreachable faster than the futures curve could reprice. The four-dollar round-trip through the $100 handle tracked the moment the market parsed the Truth Social text: blockade continues, unified-proposal condition unmet, tanker risk at the Hormuz gate unchanged. Dated Brent's refusal to settle below $96 across five sessions now is what a blockade-continues price looks like once traders stop pricing a near-term diplomatic resolution.

Deep Analysis

In plain English

Oil is priced in US dollars per barrel on global markets. Before Iran's conflict with the US began, a barrel of Brent crude (the international benchmark) cost $67.41. On 21 April it briefly crossed $100 before settling at $97.91 , a 45% increase. The jump to $100 and rapid retreat happened because markets were testing whether Trump's social media post meant the war was genuinely winding down. When traders read the post carefully and saw the blockade was still in place, the price pulled back. But it did not fall far, because the underlying blockade risk had not changed. Higher oil prices feed through to petrol and diesel costs within weeks, and also raise the price of goods that are transported or manufactured using energy.

What could happen next?

Risk
Goldman Sachs's $120 Q3 severe scenario remains live if OFAC designations follow the GL-U lapse and target specific Chinese buyers, which would remove China's demand cushion and drive a supply withdrawal.
Consequence
Brent settling above $96 for five consecutive sessions shifts institutional hedging benchmarks, locking fuel cost inflation into airline, shipping, and manufacturing forward contracts for Q3.

Source Landscape

This story draws on neutral-leaning sources from Israel

Israel

Primary parallel: During the 1990 Gulf War oil price spike, Brent crossed $40 intraday in October 1990 and retreated within hours when the market parsed the first credible diplomatic statement. The 2026 round-trip through $100 mirrors that mechanics: expirations combined with a forcing moment, one credible-seeming text (the Truth Social post), and a price collapse once traders identified the text as incomplete.

Counter-parallel: The 2019 Saudi Aramco Abqaiq attack sent Brent up 15% intraday and the price recovered fully within two weeks as spare capacity from Saudi and US sources absorbed the supply loss. The 2026 situation differs: there is no spare capacity large enough to replace Hormuz volume , so the price floor is structurally higher and a comparable diplomatic text would produce a smaller percentage drop from a higher base.

The $97.91 Brent close represents a 45% premium over the $67.41 pre-war baseline, sustained across a second consecutive expiry cycle. Goldman Sachs's $120 Q3 severe scenario , originally conditioned on a ceasefire failure , now functions as the operative forecast frame even during a ceasefire, because the blockade's continuation has decoupled the price from the ceasefire/war distinction.

The transmission channels: tanker war-risk insurance rates have increased 800-1200% above pre-war baselines for Hormuz transits; P&I clubs have imposed voyage-specific surcharges; the futures curve is inverted in the front months (backwardation), reflecting physical scarcity rather than demand-side pressure. Each of these mechanisms is slow to unwind even after a ceasefire is formalised, which is why Wood Mackenzie's Hittle assessed a $10-15 structural residual even in a full-reopening scenario.

Consensus view: Goldman Sachs commodity chief Daan Struyven and Wood Mackenzie's Ann-Louise Hittle both read the $97.91 close as a 'blockade-continues' price rather than a ceasefire price: the four-dollar round-trip through $100 on expiry morning and the fast retreat tracked exactly how quickly traders parsed the Truth Social text , blockade unchanged, unified-proposal trigger unmet, kinetic risk at Hormuz gate unresolved .

Counter-view: Vanda Insights' Vandana Hari argues that Dated Brent's refusal to settle below $96 across five sessions reflects supply-disruption pricing combined with a structural insurance premium now baked into tanker finance globally , so even a full Hormuz reopening tomorrow would leave a $10-15 residual premium in place until P&I coverage normalises.

Key tension: Whether the $97.91 price reflects a reversible geopolitical risk premium that a signed ceasefire could deflate, or whether the war has permanently re-rated the cost of Hormuz tanker insurance in a way that will outlast the blockade itself.

Different Perspectives

Shipping and insurance industry

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Russia and China

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
