PetroChina Moves 2 Million Barrels to Singapore as Iran War Strains Supply

A rare crude oil transfer from China’s strategic reserves highlights the growing strain on Asian energy supply chains as the conflict in Iran disrupts global trade.

PetroChina has supplied a rare cargo of nearly 2 million barrels of crude oil from its strategic storage to its half-owned refinery in Singapore, a significant move to plug supply shortfalls triggered by the month-old Iran war. The transfer underscores the growing pressure on Asian refiners as the conflict chokes off roughly a fifth of the world’s oil supply, much of which was destined for the region.

“Russia emerges as a major winner from the entire conflict,” said Sam Reynolds of the Institute for Energy Economics and Financial Analysis. Given the energy crisis and speed of delivery, he said Asia has "a much larger incentive to import Russian oil,” adding, “countries are going to do whatever they need to to protect their energy security.”

The conflict’s impact is rippling across global trade lanes, with oil tankers rerouting around the Strait of Hormuz and airspace restrictions complicating cargo flows. German carrier Hapag-Lloyd estimates the conflict is costing it between $40 million and $50 million per week due to higher fuel prices and operational complexity. The U.S. has temporarily eased sanctions on Russian oil shipments already at sea, first for India and then globally, to shore up supplies.

This deployment of strategic reserves by a state-owned oil major signals that geopolitical tensions are causing tangible disruptions to energy supply routes. The move highlights the vulnerability of the sector to regional conflicts and may prompt other nations to evaluate their own strategic petroleum reserves, potentially leading to increased price volatility for crude oil.

Asian Buyers Scramble for Russian Crude

With supplies from the Middle East severely curtailed, energy-hungry Asian nations are increasingly competing for a limited pool of Russian crude oil. Before the Iran war, China, India, and Turkey were the main importers of Russian oil, but the U.S. sanction waiver has prompted new interest from the Philippines, Indonesia, Thailand, and Vietnam. The Philippines, which declared an energy emergency, imported Russian crude for the first time in five years.

However, the opportunity is short-lived and shrinking. “The real problem is how much cargo is still available in this market,” said Muyu Xu, a senior crude oil analyst at the global trade data firm Kpler. Russia is already exporting near its peak capacity of around 3.9 million barrels per day, and analysts say it is unlikely to boost exports sharply. India and China, having secured cargoes early, hold an advantage, leaving other Southeast Asian nations to compete for the roughly 126 million barrels still at sea.

Ripple Effects Hit Global Shipping

Beyond the scramble for crude, the conflict is creating secondary shocks across the logistics and manufacturing sectors. Airspace closures are making it more difficult to transport engineers and spare parts, disrupting routine vessel maintenance and creating what David Fuhlbrügge of Condition Monitoring Technologies called a “double-barrelled hit” of longer transit times and rising costs. These delays risk reducing fleet efficiency and adding further strain to global shipping schedules.

The sustained pressure from higher fuel costs may also force a long-term reassessment of distribution strategies. According to Mark Russo of Savills, companies may be pushed to reduce transportation distances and move inventory closer to end consumers. This shift would likely increase demand for urban and infill logistics space across North America as firms look to offset higher shipping costs with greater proximity to their markets. The crisis also underscores how dependent global shipping remains on conventional fuels, as the infrastructure for alternatives like LNG and methanol is not yet robust enough to handle such disruptions.
