The Strait of Hormuz, located between Oman and Iran, connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. The strait is deep enough and wide enough to handle the world’s largest crude oil tankers, and it is one of the world’s most important oil chokepoints. Large volumes of oil flow through the strait, and very few alternative options exist to move oil out of the strait if it is closed. In 2024, oil flow through the strait averaged 20 million barrels per day (b/d), or the equivalent of about 20% of global petroleum liquids consumption. In the first quarter of 2025, total oil flows through the Strait of Hormuz remained relatively flat compared with 2024.
Although we have not seen maritime traffic through the Strait of Hormuz blocked following recent tensions in the region, the price of Brent crude oil (a global benchmark) increased from $69 per barrel (b) on June 12 to $74/b on June 13. This piece highlights the importance of the strait to global oil supplies.
Chokepoints are narrow channels along widely used global sea routes that are critical to global energy security. The inability of oil to transit a major chokepoint, even temporarily, can create substantial supply delays and raise shipping costs, potentially increasing world energy prices. Although most chokepoints can be circumvented by using other routes—often adding significantly to transit time—some chokepoints have no practical alternatives. Most volumes that transit the strait have no alternative means of exiting the region, although there are some pipeline alternatives that can avoid the Strait of Hormuz.
Between 2022 and 2024, volumes of crude oil and condensate transiting the Strait of Hormuz declined by 1.6 million b/d, which were only partially offset by a 0.5-million b/d increase in petroleum product cargoes. The decline in oil transit through the strait partially reflects the OPEC+ decision to voluntarily cut crude oil production several times starting in November 2022, which lowered exports from Saudi Arabia, Kuwait, and the United Arab Emirates (UAE). In addition, disruptions in 2024 to oil flows around the Bab al-Mandeb Strait, which connects the Arabian Sea to the Red Sea, led Saudi Arabia’s national oil company Aramco to shift seaborne crude oil flows from the Strait of Hormuz, instead sending it over land through its East-West pipeline to ports on the Red Sea. Also, more refining capacity in the Persian Gulf states increased regional demand for crude oil and shifted some flows to local markets within the Persian Gulf.
Flows through the Strait of Hormuz in 2024 and the first quarter of 2025 made up more than one-quarter of total global seaborne oil trade and about one-fifth of global oil and petroleum product consumption. In addition, around one-fifth of global liquefied natural gas trade also transited the Strait of Hormuz in 2024, primarily from Qatar.

Based on tanker tracking data published by Vortexa, Saudi Arabia moves more crude oil and condensate through the Strait of Hormuz than any other country. In 2024, exports of crude and condensate from Saudi Arabia accounted for 38% of total Hormuz crude flows (5.5 million b/d).
Alternative routes
Saudi Arabia and the UAE have some infrastructure in place that can bypass the Strait of Hormuz, which may somewhat mitigate any transit disruptions through the strait. The pipelines do not typically operate at full capacity, and we estimate that about 2.6 million b/d of capacity from the Saudi and UAE pipelines could be available to bypass the Strait of Hormuz in the event of a supply disruption.
Saudi Aramco operates the 5 million-b/d East-West crude oil pipeline, which runs from the Abqaiq oil processing center near the Persian Gulf to the Yanbu port on the Red Sea. Aramco temporarily expanded the pipeline’s capacity to 7.0 million b/d in 2019 when it converted some natural gas liquids pipelines to accept crude oil. In 2024, Saudi Arabia pumped more crude oil through the East-West pipeline to avoid the shipping disruptions around the Bab al-Mandeb.
The UAE also operates a pipeline that bypasses the Strait of Hormuz. This 1.8 million-b/d pipeline links onshore oil fields to the Fujairah export terminal in the Gulf of Oman. In 2024, crude oil and condensate volumes originating in the UAE and traversing Hormuz were 0.4 million b/d less than in 2022 because refinery upgrades allowed more heavy crude oil to be refined locally. These upgrades also allowed the UAE to increase exports of its lighter crude oil grades, and use of the pipeline to the Fujairah export terminal increased. Increased use of the pipeline for day-to-day operations has limited the excess capacity available to reroute additional volumes around the Strait of Hormuz.
Iran inaugurated the Goreh-Jask pipeline and the Jask export terminal on the Gulf of Oman (avoiding the Strait of Hormuz) with a single export cargo in July 2021. The pipeline’s effective capacity remains around 300,000 b/d. However, during the summer of 2024 Iran exported less than 70,000 b/d from ports (Bandar-e-Jask and Kooh Mobarak) using the Goreh-Jask pipeline and stopped loading cargoes after September 2024.
Destination markets
We estimate that 84% of the crude oil and condensate and 83% of the liquefied natural gas that moved through the Strait of Hormuz went to Asian markets in 2024. China, India, Japan, and South Korea were the top destinations for crude oil moving through the Strait of Hormuz to Asia, accounting for a combined 69% of all Hormuz crude oil and condensate flows in 2024. These markets would likely be most affected by supply disruptions at Hormuz.

In 2024, the United States imported about 0.5 million b/d of crude oil and condensate from Persian Gulf countries through the Strait of Hormuz, accounting for about 7% of total U.S. crude oil and condensate imports and 2% of U.S. petroleum liquids consumption. In 2024, U.S. crude oil imports from countries in the Persian Gulf were at the lowest level in nearly 40 years as domestic production and imports from Canada have increased.
