Asia Braces for Energy Shock as Iran Conflict Disrupts Oil Supply

Asian economies are facing significant energy challenges following disruptions to oil flows caused by the escalating conflict involving Iran. The closure of the Strait of Hormuz, a critical waterway for global oil shipments, has sent oil prices soaring and raised fears of fuel shortages across the region.

Dependence on Gulf Oil

Much of Asia is heavily reliant on oil and gas from the Gulf region. Approximately 20% of the world’s oil trade, around 19 million barrels daily, passes through the Strait of Hormuz [1]. Exports from the Gulf constitute 80% to 90% of oil imported into Japan and 30% to 40% of oil imported into China [1]. This dependence makes the region particularly vulnerable to disruptions in supply.

Government Responses

Several Asian governments have taken immediate steps to mitigate the impact of the crisis:

• Japan: Has pledged to release a record 80 million barrels of oil reserves, equivalent to roughly 45 days of supply [2]. Japan has likewise requested increased LNG output from Australia.
• South Korea: Is lifting limits on coal-fired power generation and increasing the utilization of nuclear power plants to as high as 80% [2]. Domestic fuel prices have been capped, and energy vouchers are being considered for vulnerable households.
• China: Has imposed an immediate ban on refined fuel exports, including gasoline, diesel, and jet fuel, to prevent a domestic shortage [2].
• India: Sought safe passage for 22 vessels stranded west of the Strait of Hormuz, after Iran allowed a few Indian ships to sail through [2].
• Thailand: Suspended crude and petroleum exports on March 1 [1].

Diversification Efforts and Ongoing Challenges

While some Asian countries have attempted to diversify their energy sources, including increasing imports from Russia and Central Asia, the reliance on Gulf oil remains substantial [1]. Refineries in Southeast Asia are specifically configured to process “heavy sour” or “medium sour” crude oil from the Middle East, making a swift switch to alternative suppliers difficult and costly [4].

Impact on LNG Supplies

The Strait of Hormuz is also a key transit route for Liquefied Natural Gas (LNG), with approximately one-fifth of global LNG volumes passing through its waters [1]. Around 83% of LNG exported from the Gulf is destined for Asian markets, including China, India, and South Korea.

Looking Ahead

The current crisis underscores Asia’s vulnerability to geopolitical instability in the Middle East. The long-term implications will likely include increased investment in energy diversification, renewable energy sources, and strategic oil reserves. However, in the short term, Asian economies will continue to grapple with higher energy prices and potential supply disruptions.
