The Middle East is once again at the epicenter of global anxiety, as a dramatic escalation in military actions has brought the region—and the world’s energy markets—to the brink. In the wake of airstrikes launched by the United States and Israel, Iran responded with a wave of retaliatory attacks, culminating in the Islamic Revolutionary Guard Corps (IRGC) effectively blockading the Strait of Hormuz, one of the world’s most critical maritime oil routes. The fallout has been immediate and profound, with shipping, energy prices, and international relations all thrown into turmoil.
According to multiple international sources, including the British maritime trade organization UKMTO and major news agencies, the situation reached a fever pitch on March 1, 2026. The IRGC’s blockade was not just a symbolic gesture: at least four ships were attacked in rapid succession, resulting in one fatality and several injuries among civilian crews. The Palau-flagged tanker Skylight, carrying 15 Indian and 5 Iranian crew members, was struck by a combination of drone and missile attacks near Kasab, Oman. Miraculously, all 20 crew members managed to escape, though four were injured. The vessel had previously been sanctioned by the US Treasury for transporting Iranian oil—a detail that Iran’s state media cited as justification for the attack, reporting, “We struck a tanker that attempted illegal passage in defiance of the ban.”
Elsewhere, a Marshall Islands-flagged tanker, MKDVYOM, was hit by unidentified projectiles north of Muscat, Oman, sparking a fire in the engine room and resulting in the death of one crew member. The Hercules Star was also hit near the UAE, and another unidentified projectile exploded close to a ship 35 nautical miles west of Sharjah. In these latter incidents, crews escaped without injury, but the message was clear: no vessel was safe. Even Oman, a nation traditionally playing the role of regional mediator, was not spared—its Duqm port was targeted by two drones, injuring a worker.
The IRGC claimed responsibility for missile strikes on three tankers linked to the US and UK, stating, “We targeted three US and UK tankers associated with hostile forces,” and insisted their actions were justified. The Gulf Cooperation Council (GCC), however, condemned Iran’s moves as “dangerous escalations threatening regional security.” The result has been a near-total paralysis of maritime traffic through the Strait. As reported by international agencies, the number of vessels passing through the Strait of Hormuz dropped from about 60 to single digits in a single day. Approximately 150 tankers have now abandoned attempts to transit the strait, choosing instead to anchor in international waters, waiting for the dust to settle.
The impact on global energy markets was swift and severe. According to YTN, the New York Mercantile Exchange saw April delivery West Texas Intermediate (WTI) crude oil close at $71.23 per barrel on March 2, up 6.28% from the previous close, with prices spiking as much as 12.4% intraday. Brent crude and WTI both surged around 8% in after-hours trading, threatening to breach the $70–$80 per barrel range and raising the specter of $100 oil should the conflict escalate further. UBS analyst Henri Patrico told YTN, “The key factors affecting oil prices in the coming days will be the recovery speed of traffic through the Strait of Hormuz and Iran’s retaliatory actions.”
Shipping companies have not waited for further escalation. According to Rystad Energy, many have already suspended tanker operations through the Strait. Shipping giant Maersk, for example, has halted use of the Suez Canal and is rerouting vessels around the Cape of Good Hope, a move that adds significant time and cost to global supply chains. The effective closure of the Strait of Hormuz—through which roughly 20% of the world’s oil supply transits—has sent shockwaves through the international economy.
Few countries are feeling the pressure more acutely than South Korea. With about 70% of its crude oil and 20–30% of its LNG imported from the Middle East, South Korea faces the prospect of sharp industrial cost increases if supply disruptions persist. The US-based Stimson Center warned that a prolonged conflict could “strain power supply and export competitiveness” for South Korea. Even with strategic reserves of over 100 million barrels of crude oil and about 50 days’ worth of LNG, these buffers can only cushion the blow temporarily.
The economic ramifications of a sustained blockade are daunting. Experts warn that rerouting oil shipments could increase maritime shipping costs by 50–80%, extend transport times by three to five days, and drive insurance premiums up to seven times their usual rates. Such cost increases would ripple through the global economy, hitting energy-importing nations especially hard. South Korea’s government has been urged to act swiftly, with recommendations to release strategic reserves, secure alternative sources of energy imports, and support maritime transport. Longer-term, voices in industry and government are calling for a more diversified energy strategy, including expanded renewables, nuclear power, and hydrogen.
Meanwhile, the human cost and security risks remain front and center. About 17,000 South Koreans currently reside in the Middle East, and their safety is now a top priority. The Ministry of Trade, Industry and Energy has activated an emergency response team as of March 3, 2026, to coordinate safety measures and contingency planning. Despite these efforts, uncertainty looms large. As one commentator noted, “The shadow of war in the Middle East is no longer someone else’s problem. Only a cool-headed assessment of the situation and proactive measures can minimize the economic shock.”
The prospect of further escalation cannot be dismissed. US President Donald Trump has predicted that the military operation would last “four weeks or less,” but with Gulf nations reportedly weighing whether to join the attacks on Iran, the risk of a wider conflict remains high. The closure of the Strait of Hormuz is not just about rising oil prices—it threatens to disrupt supply chains worldwide, with consequences for everything from shipping schedules to power generation. Past crises in the region have seen insurance premiums soar and shipping delays multiply, and this episode could prove even more disruptive.
For now, the world watches and waits. The next moves by Iran, the US, and their allies will determine whether this crisis deepens or begins to resolve. As UBS’s Patrico put it, the pace of recovery in Strait traffic and the nature of Iran’s next steps will “most influence oil prices in the coming days.” Until then, governments, businesses, and ordinary citizens alike are bracing for impact, hoping for swift resolution but preparing for the long haul.
