- The conflict between the US and Iran has led to shipping disruptions in the Strait of Hormuz, severely limiting the supply of crude oil and natural gas from the Middle East to Asia, and significantly increasing US exports of liquefied petroleum gas to China and Japan.
- Freight rates for liquefied petroleum gas from the Gulf of Mexico to Asia have risen to a six-year high, exceeding $300 per ton, doubling from pre-conflict levels. The high logistics costs have led some Asian buyers to cancel June shipments.
- Major global importers are forced to adjust their supply chains, with countries like India, which heavily rely on Persian Gulf energy, turning to alternative channels. Some tankers are sailing covertly by turning off their transponders to avoid geopolitical risks.
Geopolitical Conflict Disrupts Core Middle Eastern Shipping Routes
The escalation of military conflict between the US and Iran has caused severe shipping disruptions in the Strait of Hormuz, one of the world's most crucial energy corridors. The obstruction of crude oil and natural gas exports from the Middle East has led to a temporary shortage in the regular energy supply for major Asian economies. With traditional supply lines under pressure, Asian buyers are compelled to look beyond the traditional Middle Eastern markets. According to the latest data from S&P Global, this supply gap has directly increased US exports of liquefied petroleum gas (LPG) to Asia. Last month, US LPG exports to China reached 457,000 barrels per day, and to Japan, 460,000 barrels per day.
Reconstruction of Supply Chains by Major Asian Importers
The disruption in energy supply has had varied impacts on the industrial structures of different Asian countries. India, as a major global consumer of liquefied petroleum gas, previously relied on the Persian Gulf for up to 92% of its planned annual import of 2.2 million tons of LPG. Facing the current supply risk, the Indian government and energy companies are urgently seeking alternative sources. Unlike liquefied natural gas (LNG), which is primarily methane, LPG mainly consists of propane and butane, used in India mainly for residential cooking fuel, while in China, it is widely used in the chemical industry for plastic production. Given the significant uncertainty in Middle Eastern production and export prospects, analysts from the energy consultancy Vortexa indicate that US LPG supply is expected to hold a more stable share in the Asian market at least during May and June.
Rising Freight Costs and Buyer Default Risks Emerge
Although US supply has filled part of the market gap, cross-border logistics bottlenecks are becoming a core variable limiting the continued growth of trade volumes. Due to the concentrated surge in shipping demand and detour factors, LPG freight rates from the US Gulf of Mexico to Asia have soared to over $300 per ton, the highest level in six years, doubling from pre-conflict freight levels. The high transportation costs have severely eroded arbitrage profits, causing Asian buyers' purchasing intentions to waver. According to industry insiders, due to higher-than-expected landed costs, buyers have already canceled at least two batches of LPG orders originally scheduled to depart from the US Gulf of Mexico in June. If freight rates remain high, subsequent purchase volumes may be further reassessed.
Shipping Route Disruptions Trigger Covert Shipping Phenomenon
In addition to soaring freight rates, the actual turnover efficiency of tankers has significantly decreased due to the limitations of alternative routes. Ships passing through the Panama Canal face longer waiting times or need to pay high fees to jump the queue, while choosing to reroute via the Cape of Good Hope in Africa significantly lengthens the one-way journey, further exacerbating the global shipping capacity tension. Notably, despite the blockade of the Strait of Hormuz, a small amount of local Middle Eastern supply is still flowing out through extreme measures. Some LPG tankers heading to India are sailing in stealth mode by turning off their Automatic Identification System (AIS) transponders to leave the Persian Gulf. This unconventional navigation method to avoid geopolitical risks highlights the extreme pressure currently on the global energy supply chain.
