Hormuz Blockade Leaves Asia Exposed as Oil Pipelines and Pacific Routes Fall Short

Twenty Million Barrels a Day Meet a Blocked Passage

Saudi Arabia's main pipeline around the Strait of Hormuz has reached its full capacity of about 7 million barrels a day, yet only about 5 million barrels are available for export after domestic refineries take their share. That limit captures the problem facing Asia on March 28, 2026: alternative routes cannot replace a waterway that normally carries approximately 20 million barrels of oil every day.

Military strikes by the United States and Israel against Iran began on February 28. Tehran subsequently moved to halt maritime traffic through Hormuz, turning the narrow passage between Iran and the Arabian Peninsula into an effective no-go zone for the world's oil tankers. About 150 tankers carrying oil and liquefied natural gas chose to anchor rather than risk crossing hostile waters.

Brent crude, a benchmark used to price oil internationally, has climbed above $100 a barrel and reached $119 during volatile trading. The disruption is among the most severe blows to global energy supply in decades, with consequences reaching electricity systems, transport, manufacturing and food production.

Hormuz measures just 33 kilometers across at its narrowest point. Its normal oil traffic represents one fifth of global petroleum consumption and one quarter of oil traded by sea. Closing such a concentrated route creates a problem that buying from another supplier cannot quickly solve: the replacement oil must also have a usable path to the customer.

Asia receives approximately 84% of the crude oil and 83% of the liquefied natural gas passing through the strait, according to International Energy Agency and U.S. Energy Information Administration data. The region therefore faces the largest direct exposure to the interruption, even as rising prices spread the costs worldwide.

China and India Face the Biggest Volumes at Risk

China and India together received 8.2 million barrels a day of crude through Hormuz before the crisis, accounting for 44% of the strait's crude flows. Their large populations and industrial economies make replacing those supplies a substantial task.

Japan and South Korea import smaller volumes, but their dependence is especially acute because they have virtually no domestic crude production. Their economies rely on dependable imports to keep fuel supplies moving. Taiwan faces similar exposure, with energy security analysts warning that a prolonged interruption threatens industrial production across these major manufacturing economies.

China produces approximately 4.3 million barrels of crude a day domestically and holds strategic petroleum reserves estimated at 1.2 billion barrels. Strategic reserves are stored oil that can be released when normal supplies are interrupted. They provide a buffer while buyers seek replacements or wait for shipping routes to reopen.

Beijing has also pursued vehicle electrification and expanded renewable energy. Those measures reduce some demand for petroleum, but China still needs large quantities of imported oil to keep its economy functioning. The blockade is testing how much protection its domestic production, reserves and changes in energy use can provide.

Japan's strategic reserves cover nearly 150 days, helping it avoid immediate shortages. That cushion has not protected it from sustained price pressure. Stored supplies and access to affordable new supplies address different parts of the same emergency.

Two Pipelines Cannot Replace Hormuz

Saudi Arabia and the United Arab Emirates have the only operational infrastructure capable of carrying crude exports around the Strait of Hormuz. Both systems move oil overland to ports beyond the blocked passage, but their combined capacity falls far below normal traffic through the strait.

Saudi Arabia's East West Pipeline, commonly called Petroline, runs 1,200 kilometers from the Abqaiq processing center near the Persian Gulf to Yanbu on the Red Sea. Saudi Aramco chief executive Amin Nasser confirmed that it has reached its full operational capacity of approximately 7 million barrels a day.

About 2 million barrels a day supply Saudi refineries along the western coast, leaving approximately 5 million barrels for export. A pipeline's total capacity therefore gives a different picture from the amount available to foreign customers: domestic consumption takes part of the flow.

The UAE's Abu Dhabi Crude Oil Pipeline runs 360 kilometers from Habshan to Fujairah on the Gulf of Oman. It can carry between 1.5 million and 1.8 million barrels a day, although operational constraints and recent security incidents have limited actual throughput.

Together, the bypass routes can handle roughly 6 million to 7 million barrels a day, described in current estimates as covering roughly 30% of normal Hormuz traffic. The figures leave most of the usual 20 million barrels a day without an equivalent alternative route.

The U.S. Energy Information Administration notes that the pipelines generally operate below full capacity in normal conditions. Estimates put their genuinely spare capacity before the crisis at only 2.6 million barrels a day. Spare capacity means the additional oil they could carry beyond volumes already using them. Redirecting existing exports and adding new flows are therefore separate tasks, and maximum use still leaves a large gap.

Ports Outside the Strait Still Face Attack Risks

Yanbu and Fujairah move loading operations away from Hormuz, but both routes retain security risks. Saudi crude exported through Yanbu must still pass through the Bab el Mandeb strait at the southern end of the Red Sea, a waterway previously threatened by Houthi forces in Yemen.

Fujairah lies outside Hormuz but remains within range of Iranian missiles and drones. Loading operations were suspended following attacks on March 16. Storage facilities have also been hit, forcing tankers to take partial loads before departing.

Those interruptions affect how much oil reaches customers even when a pipeline is operating. Moving crude to a coastal terminal is only one stage: storage, loading and the ship's subsequent journey must also remain available.

The crisis has developed across several key dates:

• February 28, 2026: U.S. and Israeli military strikes against Iran began, followed by Tehran's move to halt maritime traffic through Hormuz.
• March 2026: Saudi crude loadings for India from Yanbu rose to 8.8 million barrels, compared with zero in previous months.
• March 16, 2026: Attacks led to the suspension of loading operations at Fujairah.
• March 28, 2026: Asian buyers continued seeking replacement supplies while pipeline capacity and security risks constrained alternatives.

Decades of Planning Left Few Other Routes

Saudi Arabia built the East West Pipeline during the Iran Iraq war to avoid attacks on maritime traffic. Hormuz had been recognized as a critical vulnerability since the 1980s, yet later upgrades concentrated on incremental expansion rather than constructing fully parallel export systems.

Gulf producers prioritized efficient routes over spare infrastructure. Building pipelines through neighboring countries also required agreement over sovereignty and security, creating political and economic obstacles to additional routes.

Iraq, Kuwait, Qatar and Bahrain have no bypass options and remain entirely dependent on Hormuz transit. The Trans Arabian Pipeline, which once connected Saudi Arabia to Lebanon's Mediterranean coast, ceased operating in 1990 and now survives as a derelict heritage site.

Daniel Yergin, an energy historian and vice chairman at S&P Global, described why the possibility of a closure did not produce a larger network of alternatives. He said policymakers viewed the worst case as unlikely and counted on importing countries to protect the shipping route:

There always has been the nightmare scenario, but it seemed to be a scenario that was not very likely. The diversification or security came from the fact that the consumers would be there to protect the oil.

The assumption that consumer nations would provide sufficient military protection reduced the economic incentive to build costly bypass infrastructure. The present interruption exposes the limits of a system designed around keeping one crucial passage open.

India Redirects Purchases, but Supply Gaps Persist

India imported approximately 40% of its crude through Hormuz before the crisis, equivalent to between 2.5 million and 2.7 million barrels a day. Its Petroleum Ministry says refiners have since diversified purchases so that 70% of supplies come through routes outside Hormuz, although a substantial supply gap persists.

Indian refiners have turned aggressively toward Saudi Arabia's Yanbu terminal and the UAE's Fujairah port. Commodity analytics firm Kpler recorded 8.8 million barrels of Saudi crude loaded at Yanbu for India in March 2026, compared with zero in previous months.

Additional volumes are arriving through the Fujairah pipeline. Tracking those movements is difficult because some vessels switch off their transponders, the devices that transmit identifying and location information, to conceal their movements near conflict zones.

New Delhi has also secured 20 very large gas carriers transporting approximately 1 million tonnes of supply from the United States, using Red Sea and Gulf of Oman alternatives. Government sources confirm that the emergency shipments are arriving but acknowledge that they cannot fully replace lost Middle Eastern volumes.

Emergency supplies from the United States and West Africa form part of India's effort to close the gap. Its experience shows both the scope for changing suppliers quickly and the limits imposed by available cargoes, ports and shipping routes.

Gas Buyers Have No Equivalent Pipeline Escape

Qatar, the world's second largest exporter of liquefied natural gas, sends virtually all of its production through Hormuz. The UAE also depends on the strait for gas exports. Together, the two countries account for nearly 20% of global LNG trade, with most of those supplies destined for Asia.

LNG is natural gas cooled into a liquid so that ships can carry it. Unlike the crude oil moved through the Saudi and UAE bypass pipelines, these LNG exports have no pipeline alternative. If liquefaction plants stop operating or cannot load tankers, their gas cannot reach overseas customers.

Qatar Energy declared force majeure shortly after the conflict began, halting production at facilities that normally process more than 112 billion cubic meters annually. Force majeure is a contract provision used when extraordinary events prevent a company from meeting its obligations.

Bangladesh, India and Pakistan import nearly two thirds of their LNG through Hormuz and depend heavily on electricity generated using gas. Pakistan derives 50% of its power from natural gas, while Bangladesh depends on it for 25% of electricity.

LNG price increases of 39% in a single trading session have added a financial shock to the shortage of supply. Governments in these countries have implemented rolling blackouts and required energy conservation measures, including university closures. Rolling blackouts spread interruptions across different areas at different times when electricity supply cannot meet demand.

The absence of a bypass makes the gas emergency especially difficult to resolve. Oil buyers can redirect some cargoes through Yanbu and Fujairah; buyers dependent on Qatari and UAE LNG must seek replacement cargoes from elsewhere.

Higher Energy Costs Reach Farms and Consumers

Gasoline, diesel, jet fuel, petrochemicals, fertilizers and basic foodstuffs have risen sharply in price as the supply disruption spreads through the economy. Oil and gas are fuels, but they also support the production and movement of goods that households buy every day.

Farmers in the Northern Hemisphere are entering the planting season with higher input costs. More expensive fertilizer and fuel threaten to push food prices higher months from now, extending the effects of the blockade beyond the immediate energy emergency.

China has ordered refiners to stop exporting fuel in order to preserve domestic supplies. South Korea has announced fuel price caps for the first time in three decades. Across Asia, governments have adopted emergency responses ranging from export bans to price controls.

Japan's substantial reserves have helped prevent immediate shortages, while continuing price pressure shows why access to stored oil does not remove the economic cost of an international supply shock. Governments must address both the amount of fuel available and the price consumers pay.

A Historic Reserve Release Would Buy Time

The International Energy Agency plans to recommend releasing 400 million barrels from strategic petroleum reserves. That would be the largest coordinated stock release in the organization's history.

The scale is large, but so is the interrupted flow. Dividing 400 million barrels by the approximately 20 million barrels normally passing through Hormuz each day gives 20 days of normal strait traffic. This comparison shows why even a historic release cannot replace continuing daily deliveries indefinitely.

No release timetable is given. Stored oil could help reduce immediate shortages while shipping and purchasing arrangements change, but the continuing task is to restore dependable flows to importing countries.

Asia's exposure also varies by fuel. Strategic petroleum reserves address oil shortages, while the LNG interruption requires replacement gas cargoes or reductions in consumption. The responses therefore have to match the fuel that each country is missing.

Canada Offers Pacific Routes, with Limits on Expansion

Asian buyers are increasingly looking across the Pacific to North America. Canada's LNG Canada project in Kitimat, British Columbia, and the expanded Trans Mountain Pipeline serving Vancouver provide routes that avoid Hormuz, the Strait of Malacca and the South China Sea.

LNG Canada has operated since June 2025. Its cargoes travel directly into the North Pacific and can reach terminals in Northeast Asia in 10 to 11 days, compared with 24 days for LNG from the U.S. Gulf Coast traveling through the Panama Canal. The shorter passage provides a practical advantage for buyers seeking supplies outside the Middle East.

Crude from Alberta can move through the Trans Mountain Expansion pipeline, which has capacity of 890,000 barrels a day. Its Pacific export route similarly avoids Middle Eastern chokepoints, although its capacity is far smaller than the 20 million barrels normally moving through Hormuz daily.

Expanding these alternatives takes years. LNG Canada Phase 2 would add 14 million tonnes of annual capacity, with a final investment decision under consideration for late 2026 or early 2027. That decision would determine whether the proposed expansion proceeds.

The proposed Alaska LNG project has support from the Trump administration but lacks binding contracts. Exports would not begin before 2031 at the earliest. Canadian Pacific infrastructure offers an alternative viewed as geopolitically stable, while the timetable for larger supplies extends well beyond the immediate emergency.

Asia's current choices therefore combine emergency purchases, reserve use, conservation and limited rerouting. The Saudi and UAE pipelines provide some relief, and Pacific supplies broaden purchasing options, but neither can quickly replace the oil and gas normally moving through Hormuz.
