Twin Chokepoints: Hormuz Shut, Red Sea Under Fire as Oil Supply Disruption Tops 2 Billion Barrels

Two chokepoints, one squeeze

The global oil market is facing a twin-chokepoint crisis that shows no sign of resolving. In the east, the Strait of Hormuz has been effectively closed to commercial shipping for 165 days since Iran’s February 28 closure declaration.^[1] War-risk insurance has priced transit beyond the reach of most operators, and four of the world’s largest container carriers have stopped using the route.^[1] In the west, Yemen’s Houthis have opened a second front, declaring a maritime blockade on Saudi Arabia and striking Aramco’s Jazan refinery on the Red Sea coast with a drone on August 9.^[2]

The result is an extraordinary strategic squeeze. Saudi Arabia had been rerouting crude toward its Red Sea coast to bypass Hormuz — but the Houthi blockade on the adjacent Bab al-Mandeb strait has halved Saudi crude exports through that route, from 3.2 million barrels per day earlier in the conflict to roughly 1.5 million b/d now.^[2] Hormuz shut in the east, Red Sea under threat in the west, and the kingdom caught between both.

The supply disruption is now structural

Energy Intelligence calculates that the Iran war has produced an average 12.9 million barrel-per-day reduction in seaborne supplies of crude oil, refined products, LPG, and ethane since February 28. The aggregate disruption surpassed 2 billion barrels at the start of August — the equivalent of nearly 19 days of total global output at prewar levels.^[3] That is not a temporary spike; it is a semi-permanent shock that analysts now say must be factored into medium-term supply outlooks, not just short-term ones.^[3]

LNG exports through Hormuz have collapsed by 95%, according to the United Nations.^[1] The disruption extends well beyond energy: fertilizer, industrial chemicals, and grain shipments are all caught in the bottleneck.

Oil prices hold above $83 as talks stall

Brent crude settled at $88.98 per barrel on August 12, up 0.08%, after jumping roughly 5% on Monday when Trump introduced new compensation demands against Iran.^[4] WTI traded near $83.91.^[4] Both benchmark contracts posted their highest closes since July 31.^[4]

The catalyst for the latest leg up was the collapse of negotiating momentum. The United States and Iran have exchanged new, maximalist demands: Iran’s Supreme National Security Council issued six conditions including lifting the US naval blockade, withdrawing US forces, ending sanctions, and releasing frozen assets.^[5] Trump responded by demanding Iran compensate families for deaths and injuries spanning decades, including USS Cole casualties and Iranian protesters killed in January unrest.^[5]

Analysts characterize both sets of demands as deliberately expansive. “Both sides appear to be putting forward maximalist demands ahead of serious negotiations,” said Negar Mortazavi, senior fellow at the Centre for International Policy.^[5] Oil prices jumped more than 5% on Monday after Trump’s new demands and rose again Tuesday as hopes for a deal faded.^[5]

A new defence pact reshapes the regional chessboard

On August 7, Saudi Arabia, Turkey, and Pakistan signed a mutual defence pact at the Makkah Summit, stipulating that an attack against any one of the three “shall be regarded as an attack against them all.”^[6] The agreement does not specify binding military actions, but it signals Riyadh’s intent to build a deterrence framework as it confronts threats from both the Houthis and Iran-aligned Iraqi militias.^[2]

The pact adds a new variable to any escalation scenario. A Saudi official told CNN the kingdom was bracing for “multiple coordinated attacks” by Iraqi militia factions and Houthis, citing intelligence reports of imminent operations under IRGC guidance.^[2] Whether the Turkey-Pakistan commitment translates into concrete military support remains an open question — but it raises the cost of any attack on Saudi territory and complicates Tehran’s calculus.

Markets are pricing the standoff, not the breakout

The S&P 500 rose 0.27% to 7,749 on August 12, helped by cooler-than-expected July CPI, while the Nasdaq gained 0.54% to 26,588.^[7] But energy and defense names tell a different story beneath the surface.

The Energy Select Sector SPDR (XLE) closed at $61.03, essentially flat on the day after a 3.3% sector drop the prior session.^[7] The ETF is still up roughly 20% over the past 90 days and 29% over the past year, reflecting how the Iran war has driven massive short-term profits in oil — but analysts caution that geopolitics is a risky trade to bank on.^[8] Seeking Alpha flagged the “Hormuz problem” hanging over XLE’s 40% rally, questioning whether the gains are sustainable if the strait reopens.^[8]

ExxonMobil (XOM) closed at $159.76, down 0.03%, and Chevron (CVX) at $196.56, down 0.05% — both essentially flat as the market digests conflicting signals.^[9] The major integrateds have delivered blowout earnings on the war premium, but their stock prices suggest the market is uncertain whether to price the disruption as permanent or transitory.^[8]

Frontline (FRO), the tanker operator, was the standout mover, up 3.75% to $39.57.^[9] Scarcity of available tankers — as ships divert around the Cape of Good Hope and Chinese supertankers take Africa detours to avoid Red Sea attacks^[10] — is the clearest mechanical beneficiary of the chokepoint crisis. FRO’s outperformance vs. the integrated majors captures the market’s read: the disruption in shipping capacity is real and quantifiable, even if the oil price level itself is a political coin flip.

On the defense side, Lockheed Martin (LMT) rose 1.50% to $606.72^[9], while Raytheon parent RTX slipped 0.49% to $222.76^[9]. The defense trade is more nuanced than energy: depleted missile inventories and replenishment demand are durable, but a ceasefire could reveal which defense names have sustained demand and which were riding a temporary war premium.^[8]

What to watch next

• Iran-Oman shipping arrangement: Foreign Minister Araghchi says negotiations with Oman over new shipping lanes through Hormuz are in “final stages.”^[5] Any announcement of an Oman-managed corridor would be the most concrete de-escalation signal yet — but Iran’s six conditions remain unresolved.
• Houthi escalation against Saudi Red Sea infrastructure: The Jazan refinery strike and the declared maritime blockade of Saudi Arabia mark a clear escalation pattern.^[2] If Houthi attacks extend north toward Yanbu — Saudi Arabia’s main Red Sea export terminal — the supply impact intensifies materially. Tankers are already concealing Yanbu calls to avoid targeting.^[11]
• The Saudi-Turkey-Pakistan pact’s first test: The August 7 defence agreement^[6] has not yet been tested. Saudi intelligence reports of imminent coordinated attacks by Iraqi militias and Houthis^[2] could trigger the pact’s mutual-defence clause — or expose its limits.
• US crude inventory data: Swelling US crude stockpiles^[4] are providing a partial offset to the Hormuz disruption. Weekly inventory prints will show whether domestic supply is adequate to buffer the import disruption, or whether the squeeze is tightening.
• CPI vs. oil passthrough: July CPI came in cooler than expected on August 12,^[12] but with Brent above $89, the lagged passthrough of energy costs into inflation is the variable that could shift Fed expectations — and with them, the equity market’s risk appetite.

The base case is that this crisis grinds on. Both sides have entrenched, maximalist positions; the chokepoints are physical and cannot be reopened by rhetoric alone; and the 2-billion-barrel disruption has already reshaped medium-term supply curves. The risk case is that any single incident — a tanker sinking, a refinery hit, a miscalculated strike — converts the standoff into a breakout. Markets are pricing the first scenario. The second remains the tail risk that no one can quantify.
