The restructuring of supply chains, forced by the current geopolitical crisis, is set to fundamentally diminish the monopoly held by Middle Eastern resource nations in key chemical materials over the long term.
Recent military actions by the United States and Israel against Iran have completely upended the global energy and chemical supply chain landscape. While a direct confrontation is not feasible for Iran, inaction was also not an option. Consequently, Iran swiftly adopted an asymmetric strategy, retaliating by blockading the Strait of Hormuz.
The blockade of the Strait of Hormuz has thrown global energy and chemical supply chains into disarray. Although the Strait's narrowest point is only 29 nautical miles wide, with a two-way deep-water channel merely 2 nautical miles across, its strategic position guarding the major crude oil and natural gas export hubs of the Persian Gulf—including Saudi Arabia's Dammam, Qatar, Kuwait, Bahrain, and Iraq—grants it immense importance in global crude oil logistics. Prior to the blockade, the Strait facilitated the daily transit of approximately 20 million barrels of crude oil and petroleum products. This volume represents 25% of global seaborne oil trade and equates to 20% of the world's daily consumption. This figure does not even include the roughly 20% of global liquefied natural gas (LNG) trade that passes through—approximately 93% of Qatar's (the world's largest LNG exporter) LNG exports rely on the Strait, while the figure is 96% for the UAE. The blockade effectively erased 20% of global LNG supply overnight (around 10.8 billion cubic feet per day).
Given that petrochemicals are deeply integrated into daily life, this disruption has severely impacted transportation, chemicals, semiconductors, and even fertilizers. Nations reliant on crude oil imports are the first to feel the effects. Geographically, oil supply chains exhibit a distinct proximity bias to minimize transport distances. The primary buyers of Middle Eastern crude are European and Asian countries—2024 data indicates that about 70% of the crude oil and condensate from the Strait flows to China, India, Japan, and South Korea, with another 14% going to other Asian nations.
Significant shifts have occurred in global oil and gas production and consumption since 2010. On the production side, the most notable change stems from the United States: in 2010, the U.S. produced 7.62 million barrels per day (bpd), ranking third behind Russia and Saudi Arabia; by 2024, U.S. production had surged to 20.23 million bpd, making it the world's largest producer. On the consumption side, the major change is China's growth from 10.58 million bpd to 17.85 million bpd. Although China remains the second-largest oil consumer after the U.S., this growth has propelled the Asia-Pacific region past the Americas to become the largest oil-consuming region globally.
These opposing trends reveal intriguing dynamics. The first major change is the declining reliance of the United States on crude oil imports. In 2010, the U.S. required daily imports of 11.77 million barrels; by 2024, this figure had plummeted to just 190,000 bpd, less than one percent of the previous level. Considering the Americas as a whole, and factoring in consistent exports from neighboring Canada, the region has transformed from a net importer of 8.86 million bpd to a net exporter of 4.38 million bpd.
The second change is the increasing crude oil demand from the Asia-Pacific region, led by China. The region's daily demand has grown from 19.23 million barrels to 31.14 million barrels. Even excluding China, demand rose from 13.83 million to 18.55 million bpd.
Analyzing global oil export regions highlights the dominance of the Middle East and the Commonwealth of Independent States (Russia and five Central Asian nations), followed by Africa and, more recently, the Americas. Combined, the Middle East and CIS provide approximately 30 million bpd of supply, for which substitutes are scarce in the short term. This is particularly critical for Europe, Japan, and South Korea (and regions like Taiwan, China, unable to import Russian energy), which have deliberately severed imports of Russian energy following the Ukraine conflict. Having lost Russian supplies, these regions have become more dependent on Middle Eastern nations. Consequently, this over-reliance on a single region leaves them highly vulnerable to supply shocks like the current one.
Conversely, Middle Eastern oil-producing nations themselves are excessively dependent on the Strait of Hormuz. The region's pipeline infrastructure capable of bypassing the Strait is extremely limited, relying mainly on strategic assets in Saudi Arabia and the UAE. The primary alternative is Saudi Arabia's 750-mile East-West Crust Oil Pipeline, linking the Abqaiq oil fields in the east to the Yanbu port on the Red Sea. However, built in the 1980s with a maximum capacity of only 7 million bpd, it is insufficient to handle the Strait's normal daily throughput of 20 million barrels, meeting roughly just a third of the demand. For natural gas, bypass options were largely not considered historically.
The immediate result has been government intervention to calm market panic and curb inflation through strategic reserve releases. The U.S. Energy Department released 172 million barrels of crude to stabilize markets, while the International Energy Agency (IEA) coordinated a joint release totaling 400 million barrels. The U.S. release of 172 million barrels is significant—it is the second-largest historic release after the 180 million barrels released by the Biden administration in 2022, depleting U.S. reserves to their lowest level. Yet, the 400 million barrels globally are a drop in the ocean; with a daily shortfall of 10 million barrels from the Middle East, these reserves would sustain the market for only about 40 days. Ironically, to alleviate extreme supply pressure, the U.S. Treasury Department was forced to compromise, announcing a 30-day exemption allowing countries to purchase sanctioned Russian crude.
Beyond oil itself, other industries are inevitably affected. Three key examples illustrate this: 1. **Semiconductors:** In semiconductor manufacturing, helium is indispensable for cooling silicon wafers and sensitive optical components due to its superior thermal conductivity and chemical inertness. As helium is a byproduct of natural gas extraction, its global supply chain is heavily concentrated in the Gulf region, with Qatar alone accounting for 40% of global helium production capacity. 2. **Agriculture:** Agricultural production depends on fertilizers, which in turn rely heavily on nitrogen-based fertilizers like urea, produced from natural gas. This makes the global fertilizer supply chain highly dependent on the Gulf region. The timing is critical, coinciding with the key spring planting season in the Northern Hemisphere, meaning fertilizer price spikes could be devastating for farmers. 3. **Chemical Industry:** The petrochemical industry is the foundation for plastics, synthetic fibers, synthetic rubber, and other essential materials for modern manufacturing. Therefore, a disruption in petroleum product supply will cascade like dominoes through downstream sectors including packaging, construction materials, textiles, apparel, and consumer goods, ultimately triggering widespread global inflation.
However, this crisis also presents opportunities. For Chinese enterprises, and indeed for Chinese manufacturing as a whole, that can maintain stable supplies, this is a rare opening. From a broader perspective, the supply chain restructuring forced by this geopolitical crisis may, in the long run, fundamentally weaken the monopolistic position of Middle Eastern resource countries in core chemical materials, thereby profoundly altering the underlying dynamics of global geopolitical competition.
