1. Why the Strait of Hormuz Is Still the World’s #1 Oil Chokepoint
In 2024, tankers moved 20.3 million barrels per day of crude oil and petroleum products through the Strait of Hormuz. That’s from the US Energy Information Administration’s July 2024 “World Oil Transit Chokepoints” report. Global oil consumption was 102.9 million b/d that year. So Hormuz carries about 1 in 5 barrels the world uses.
The main exporters using the strait: Saudi Arabia, Iraq, UAE, Kuwait, Qatar, and Iran. The main buyers: China, India, Japan, and South Korea took 69% of Hormuz crude and condensate flows in 2023. Europe took about 18%.
2. Interactive Map: Strait of Hormuz Shipping Lanes
The strait is only 21 nautical miles wide at its narrowest point, with 2-mile-wide shipping lanes for inbound and outbound traffic. Zoom and pan the map to see major terminals at Kharg Island, Ras Tanura, and Fujairah.

Table 1: Major Oil Chokepoints vs 2024 Daily Flow
| Chokepoint | 2024 Oil Flow | Share of Global Seaborne Oil | Primary Risk Factor |
|---|---|---|---|
| Strait of Hormuz | 20.3 million b/d | ~30% | US-Iran geopolitical tension |
| Strait of Malacca | 23.7 million b/d | ~35% | Piracy, vessel congestion |
| Suez Canal + SUMED Pipeline | 8.8 million b/d | ~13% | Regional conflict, physical blockage |
| Bab el-Mandeb Strait | 8.6 million b/d | ~13% | Yemen conflict, Houthi attacks |

3. US-Iran Sanctions: 2018 to 2026 Data
The US withdrew from the Joint Comprehensive Plan of Action in May 2018. The policy goal, per US Treasury OFAC, was to reduce Iran’s oil exports to “zero” to pressure Tehran on nuclear and missile programs.
Table 2: Iran Crude + Condensate Exports
| Period | Avg Exports | Main Buyers | Policy Context |
|---|---|---|---|
| April 2018 | 2.8 million b/d | China, India, S. Korea, Japan, EU | Pre-JCPOA withdrawal |
| May 2019 | 0.4 million b/d | China, Syria | US waivers expired |
| 2021 Average | 0.8 million b/d | China “teapot” refineries | Maximum pressure campaign |
| 2023 Average | 1.3 million b/d | China 90%+ | Selective enforcement |
| Q1 2026 Est | 1.4 to 1.6 million b/d | China, via Malaysia transfers | Per TankerTrackers.com |

4. The Hidden Tax: Tanker Insurance and War Risk
The Joint War Committee at Lloyd’s of London keeps the Persian Gulf on its “Listed Areas.” Q1 2026 premiums are 0.10% to 0.15% of hull value, according to Marsh McLennan’s 2026 Political Risk Map. On $80 oil, that’s $0.80 to $1.20 per barrel in extra cost.
“Geopolitical risk is a structural component of the oil price. The market prices it daily through freight and insurance.”
— Fatih Birol, Executive Director, International Energy Agency, World Energy Outlook 2023
5. Can Pipelines Bypass Hormuz? The Math
Saudi East-West Pipeline: 5 million b/d capacity to Yanbu. Ran ~2.1 million b/d in 2024.
UAE Habshan–Fujairah Pipeline: 1.5 million b/d to the Gulf of Oman. Ran ~1.2 million b/d in 2024.
Total bypass used: 3.3 million b/d vs 20.3 million b/d through Hormuz.
Iran’s Goreh-Jask pipeline has 1 million b/d capacity and ran ~0.3 million b/d in 2024, per Shana news agency.
6. Argentina’s Vaca Muerta: Reserves, Production, Breakevens
The EIA’s 2013 assessment, updated 2022, estimates Vaca Muerta holds 16.2 billion barrels of technically recoverable shale oil and 308 Tcf of shale gas.
Table 3: Vaca Muerta Production Growth
| Year | Vaca Muerta Oil b/d | Argentina Total Oil b/d | Source |
|---|---|---|---|
| 2018 | 90,000 | 490,000 | Argentine Secretariat of Energy |
| 2021 | 210,000 | 540,000 | Argentine Secretariat of Energy |
| 2024 | 355,000 | 680,000 | Argentine Secretariat of Energy |
| 2025 Estimate | 410,000 | 740,000 | Rystad Energy, Dec 2025 |
| 2030 Target | 1,000,000 | 1,300,000 | YPF Corporate Plan 2024 |

Vaca Muerta spans ~30,000 sq km in Neuquén Province. The map shows the main producing blocks: Loma Campana, La Amarga Chica, and Bajada del Palo.

Breakevens are $35-$45/bbl per Wood Mackenzie 2025. For geology, see Vaca Muerta vs Permian: Why Geologists Are Excited.
9. How Non-OPEC Supply Changes Hormuz Risk Premiums
The IEA Oil Market Report, April 2026 models that each 1 million b/d of new supply outside Hormuz reduces the risk premium. If Guyana, Brazil, Canada, and Argentina add 5 million b/d by 2030, a full Hormuz shutdown affects 15% of global supply instead of 20%.
