China Less Vulnerable to Oil Price Surges Amidst Iran Conflict Due to Strategic Reserves and Energy Diversification

Surging oil prices, a direct consequence of the unfolding Iran war, are poised to exert a less severe impact on China’s economy compared to historical precedents. This reduced vulnerability is attributed to the nation’s substantial crude oil stockpiles and its ongoing diversification of energy sources, with a significant pivot towards renewable energy playing a crucial role.

As crude oil prices breached the $100 per barrel mark for the first time in four years, analysts at OCBC noted that China’s sensitivity to a prolonged closure of the Strait of Hormuz is likely to be considerably lower than that of many of its Asian counterparts. This resilience stems from China’s accumulation of one of the world’s largest strategic and commercial crude reserves. Furthermore, the country’s accelerated transition to electric vehicles and renewable energy sources provides an additional structural hedge against oil price volatility.

As of January, China held an estimated 1.2 billion barrels of onshore crude stockpiles. This reserve is equivalent to approximately three to four months of supply, a buffer that is expected to delay any significant economic repercussions, according to Rush Doshi, director of the China Strategy Initiative at the Council on Foreign Relations. Doshi highlighted that over the past two decades, China has strategically reduced its reliance on maritime oil flows. The development of new overland oil pipelines and increased investment in renewable energy have meant that the country now depends on the Strait of Hormuz for only about 40% to 50% of its seaborne oil imports.

China has set an ambitious target to increase the share of non-fossil fuels in its total energy consumption to 25% by 2030, a notable increase from the 21.7% recorded in 2025. The Strait of Hormuz, a critical chokepoint connecting the Persian Gulf to the Arabian Sea, is a narrow passage bordered by Iran to the north and Oman and the United Arab Emirates to the south. In the previous year, approximately 31% of the world’s seaborne oil flows, translating to around 13 million barrels per day of crude, transited through this vital waterway, according to data from Kpler.

However, the significance of these oil shipments to China’s overall energy consumption is relatively modest. Ting Lu, chief China economist at Nomura, pointed out that oil shipments through the Strait of Hormuz account for only 6.6% of China’s total energy consumption. Natural gas imports via the same route constitute an additional 0.6%. This shift underscores a two-decade-long strategic transition that has positioned China uniquely within the global energy landscape.

The United States stands as the world’s largest consumer of oil, followed by China and India, as per data from the Organization of the Petroleum Exporting Countries (OPEC). However, China is the preeminent crude importer, sourcing nearly twice the volume imported by the U.S., with India ranking third. Analysis of U.S. Energy Information Administration data for 2023 reveals that India is the most dependent on petroleum imports among the three, with these imports accounting for one-fourth of its total consumption. In contrast, China’s reliance was lower at 14%, while the U.S. produced the majority of its petroleum needs.

Diverging Energy Strategies

While the United States has significantly ramped up its domestic oil production over the past decade, China has pursued a vigorous strategy of diversifying its energy sources. Renewables, excluding nuclear and hydropower, constituted 1.2% of China’s total energy consumption in 2023, a substantial increase from the mere 0.2% recorded two decades prior. This trend is notably higher than the shares observed in India and the U.S. for the same year, which both recorded 0.2% for renewables.

Although currently a small percentage, the growing share of renewables in China’s energy mix carries significant global implications. The nation’s aggressive push towards electric vehicles, particularly in the commercial truck sector, has already displaced over one million barrels per day of implied oil demand, according to a July 2025 report by Rhodium Group. The research firm projected this figure to rise by approximately 600,000 barrels per day in the subsequent twelve months. Currently, more than half of the new passenger vehicles sold in China are new-energy vehicles, indicating a growing preference for battery-powered transportation over gasoline-dependent models.

Analysts at OCBC observed that with road fuel demand showing signs of peaking and renewable capacity expanding rapidly, China’s sensitivity to oil price fluctuations is diminishing on a year-on-year basis. The ongoing electrification of transportation and the expansion of renewable power generation are expected to further insulate the Chinese economy from oil-related shocks. In terms of the power generation mix, oil and natural gas collectively account for a mere 4% of China’s energy supply, a figure significantly lower than the 40% to 50% observed in many other Asian economies. Electricity, predominantly generated from coal and an increasing proportion of renewables, now represents a growing share of China’s total energy consumption, according to the energy think tank Ember.

Fossil Fuels Still Loom Large

Renewables were responsible for approximately 80% of China’s new electric power demand in 2024, as reported by Ember. Nevertheless, coal continues to be a significant, albeit stagnating, energy source within the country. Despite concerted efforts to reduce carbon emissions, China remained the world’s largest producer and consumer of coal in 2023.

In the context of U.S. sanctions on Iran, China has emerged as one of the few significant buyers of Iranian oil. Ano Kuhanathan, Head of Corporate Research at Allianz Trade, indicated that Iran accounted for approximately 20% of China’s oil imports, though this volume could largely be substituted by increased imports from Russia. The more substantial risk, Kuhanathan noted, pertains to the roughly 5 million barrels per day of oil that China imports from other Middle Eastern countries through the Strait of Hormuz.

As the Iran war enters its second week, the duration of the conflict remains uncertain. Muyi Yang, senior energy analyst, Asia, at Ember, suggested that such a shock would likely reinforce the current trajectory of China’s energy policies rather than instigate a change. She emphasized that the situation highlights the inherent risks of heavy reliance on imported oil and gas, underscoring the importance of not only expanding wind and solar capacity but also pursuing economy-wide decarbonization.

However, the transition away from fossil fuels is not without its challenges. The dominance of state-owned corporations within China’s fossil fuel industry may present obstacles to rapid change, as these entities tend to be less agile than their private-sector counterparts. China may also continue to bolster its strategic crude reserves. The U.S. Energy Information Administration projected in February that China would expand its strategic stockpiles by around 1 million barrels per day in 2026.

Data from Wind Information indicated a nearly 2% drop in China’s crude oil imports in 2024. However, as tensions in the Middle East escalated last year, China’s crude imports saw a notable increase of 4.6%, reaching a record of approximately 580 million metric tons. Go Katayama, principal insight analyst at Kpler, previously commented to CNBC that China is "materially exposed but more flexible."
