Iran War Triggers Energy Crisis, Threatening Global Economy

As the conflict in the Middle East continues to escalate, the global economy is bracing for serious repercussions, particularly in Europe and Asia. The ongoing war, particularly between the U.S. and Israel against Iran, has led to significant disruptions in oil supplies, sending prices soaring and raising concerns about inflation and economic stagnation across various regions.

According to a recent report by the Korea Institute for Industrial Economics & Trade (KIET), a 10% rise in global oil prices would result in an average increase of 0.71% in manufacturing costs for South Korea. This figure underscores the heavy reliance of the Korean economy on energy imports, with 70.7% of its crude oil sourced from the Middle East. Alarmingly, 99% of those shipments pass through the Strait of Hormuz, which has been largely blocked due to the ongoing conflict.

As of March 16, 2026, the price of Dubai crude—a benchmark for oil imported into Korea—hit $145.51 per barrel, nearly double the $71.24 recorded just weeks earlier, before the U.S.-Israeli strikes on Iran began. This dramatic increase in oil prices is expected to have a cascading effect on various sectors, especially energy-intensive industries like petroleum and chemicals, which may see production costs rise by 6.3% and 1.59%, respectively.

The situation is similarly dire in Europe, where the war is poised to deliver a punishing blow to the economy. After a prolonged period of stagnation, policymakers had hoped to accelerate growth this year, but the new energy shock complicates those plans. European governments are scrambling to provide relief, yet their options are significantly constrained compared to the responses during Russia's invasion of Ukraine four years ago. Higher government debt and borrowing costs, coupled with the absence of pandemic stimulus money, limit the tools available to policymakers.

As the conflict enters its third week, at least 15% of the world's oil supplies remain trapped in the Gulf, following the closure of the Strait of Hormuz, a critical maritime chokepoint. Reports indicate that Saudi Arabia is attempting to divert as many as 5 million barrels a day to the Red Sea port of Yanbu, while the United Arab Emirates is rerouting some crude exports through the Fujairah oil terminal. Despite these efforts, approximately 15 million barrels per day of Middle Eastern supply remain shut out of global markets, marking an unprecedented disruption in the post-World War II era.

The surge in oil prices has pushed Brent crude above $100 a barrel, with global prices for refined fuels like diesel and jet fuel rising even more sharply. Iran's Supreme Leader Mojtaba Khamenei has declared that the Strait of Hormuz will remain closed, although he has suggested that individual countries could coordinate ship movements with Iran's navy. The U.S. Navy currently lacks the capability to forcibly reopen the waterway, and while financial guarantees have been offered to commercial shippers to mitigate war-related losses, many remain unwilling to take the risk.

In a bid to cushion the blow to the oil market, the Trump administration has been exploring various measures. These include allowing countries to purchase sanctioned Russian crude oil and petroleum products currently at sea, a move that could potentially release significant volumes into the market. However, the actual relief may be limited, as countries like China, India, and Turkey have already been purchasing the bulk of Russia's oil despite Western sanctions.

The International Energy Agency (IEA) has also announced plans for its 32 member countries to release 400 million barrels from emergency reserves, a move that represents a historic drawdown equivalent to about one-third of the total strategic petroleum reserves managed by the agency. The United States will contribute 172 million barrels, but this still leaves Washington with only around 100 million additional barrels that could be tapped easily due to technical and operational limitations.

As countries in Asia begin to feel the impact of these disruptions, some are already moving toward fuel rationing. Governments from South Korea to Sri Lanka may be forced to implement such measures, further damaging their already fragile economies. Refineries across Asia are cutting operating rates to conserve crude, and some governments are ordering employees to work from home or even scrapping fuel duties to shield consumers from skyrocketing prices.

The report from KIET highlights the urgency of the situation, recommending that Korea diversify its energy supply chains and expand its strategic oil reserves. It warns that policymakers must prepare for the risk of stagflation—a combination of rising inflation and economic stagnation—as higher oil prices could push up production costs and weigh heavily on real economic activity.

“We need to respond to rising manufacturing costs and growing inflationary pressure,” said Hong Sung-wook, a senior researcher at KIET. “The government should establish tailored industrial responses and support systems for companies based on each sector’s energy dependence and supply chain structure.”

As the international community watches the situation unfold, the interconnectedness of global economies becomes increasingly apparent. The ramifications of the conflict in the Middle East are not confined to the region; they ripple through supply chains and markets worldwide. With no clear end in sight for the hostilities, the pressure on global oil supply chains is likely to intensify, further complicating the economic landscape.

In summary, as Europe and Asia grapple with the fallout from the Iran war, the need for strategic planning and robust responses becomes more critical than ever. The current crisis serves as a stark reminder of the vulnerabilities inherent in global energy dependence and the far-reaching consequences of geopolitical conflicts.
