The war between the United States (US) and Israel against Iran that erupted in late February 2026 sparked concerns about the closure of the Strait of Hormuz.
The Strait of Hormuz is a shipping route in the Middle East that passes through part of Iran, which plays a crucial role in global oil trade.
"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," said the U.S. Energy Information Administration (EIA) in its report Amid regional conflict, the Strait of Hormuz remains a critical oil chokepoint (June 2025).
"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," they said.
According to EIA data, in the first quarter of 2025, the volume of oil supplies sent through the Strait of Hormuz reached 20.1 million barrels per day (combined crude oil, condensate, and oil products).
This figure equates to 19.69% or roughly a fifth of total global oil consumption.
In the first quarter of 2025, the largest volume of oil supplies passing through the Strait of Hormuz was sent to China, with a volume of 5.35 million barrels per day (combined crude oil and condensate, excluding oil products).
During the 2020-2024 period, China was also consistently the largest destination for oil shipments via this route, followed by India, South Korea, and Japan.
Meanwhile, shipments to countries outside Asia, such as Europe and the United States, were minimal as shown in the graph.
"China, India, Japan, and South Korea were the top destinations for crude oil moving through the Strait of Hormuz to Asia. These markets would likely be most affected by supply disruptions at Hormuz," said EIA.
