TOKYO, June 23, 2025 (BSS/AFP) - Around 84 percent of oil passing through the 
Strait of Hormuz is destined for Asia, leaving the economies of China, India, 
South Korea and others vulnerable should Iran blockade the crucial trading 
route over US strikes on its nuclear sites.

Around 14.2 million barrels of crude oil and 5.9 million barrels of other 
petroleum products pass through the strait per day -- representing around 20 
percent of global production in the first quarter, according to the US Energy 
Information Administration (EIA).

And crude oil from Saudi Arabia, the UAE, Iraq, Kuwait, Qatar and Iran almost 
exclusively passes through the corridor.

Here are the main Asian countries where oil exported via the strait is 
destined:

- China -

More than half of the oil imported by East Asia passes through the Strait of 
Hormuz, experts estimate.

China is one of the largest buyers, importing 5.4 million barrels of crude 
oil a day through Hormuz in the first quarter this year, according to the 
EIA.

Saudi Arabia is China's second-largest supplier of crude oil, accounting for 
15 percent of its total oil imports -- 1.6 million barrels a day.

China also buys more than 90 percent of Iran's oil exports, according to the 
analysis firm Kpler.

It imported 1.3 million barrels of Iranian crude oil a day in April, down 
from a five-month high in March.

- India -

India is highly dependent on the Strait of Hormuz, importing 2.1 million 
barrels of crude a day through the corridor in the first quarter, EIA data 
shows.

Around 53 percent of India's imported oil in early 2025 came from Middle 
Eastern suppliers, particularly Iraq and Saudi Arabia, local media reported.

Wary of an escalating conflict in the Middle East, New Delhi has increased 
its imports of Russian oil over the past three years.

"We have been closely monitoring the evolving geopolitical situation in the 
Middle East since the past two weeks," India's Minister of Petroleum and 
Natural Gas Hardeep Singh Puri said on Sunday.

"We have diversified our supplies in the past few years and a large volume of 
our supplies do not come through the Strait of Hormuz now," he wrote on X, 
adding "We will take all necessary steps to ensure stability of supplies of 
fuel to our citizens."

- South Korea -

Around 68 percent of South Korea's crude oil imports pass through the Strait 
of Hormuz -- 1.7 million barrels a day this year, according to the EIA. 

South Korea is particularly dependent on its main supplier Saudi Arabia, 
which last year accounted for a third of its oil imports.

Seoul's trade and energy ministry said there have been "no disruptions so far 
in South Korea's crude oil and LNG imports" but "given the possibility of a 
supply crisis", officials were "planning for potential disruptions in the 
Strait of Hormuz".

"The government and industry stakeholders have prepared for emergencies by 
maintaining a strategic petroleum reserve equivalent to about 200 days of 
supply," the ministry said in a statement.

- Japan -

Japan imports 1.6 million barrels of crude oil a day through the Strait of 
Hormuz, the EIA says.

Japanese customs data showed 95 percent of crude oil imports last year came 
from the Middle East.

The country's energy freight companies are readying for a potential blockade 
of the strait.

"We're currently taking measures to shorten as much as possible the time 
spent by our vessels in the Gulf," shipping giant Mitsui OSK told AFP.

- Others -

Around 2 million barrels of crude oil passing through the Strait of Hormuz 
each day in the first quarter were destined for other parts of Asia -- 
particularly Thailand and the Philippines -- as well as Europe (0.5 million 
barrels) and the United States (0.4 million barrels).

- Limited alternatives -

Asian countries could diversify their oil suppliers, but it is difficult to 
replace the large volumes coming from the Middle East.

In the short term, "elevated global oil inventories, OPEC+'s available spare 
capacity, and US shale production all could provide some buffer", experts at 
MUFG Bank said.

"However, a full closure of the Hormuz Strait would still impact on the 
accessibility of a major part of this spare production capacity concentrated 
in the Persian Gulf," they said.

Saudi Arabia and the UAE have infrastructure to bypass the strait, 
potentially mitigating disruptions, but their transit capacity remains very 
limited -- around 2.6 million barrels a day.

And the Goreh-Jask pipeline built by Iran to export via the Gulf of Oman, 
which has been inactive since last year, has a maximum capacity of only 
300,000 barrels per day, according to the EIA.
