Brent crude futures climbed above $105–$106 per barrel this week, marking the highest price levels since July 2022, as geopolitical tensions in the Middle East entered their third week and energy markets reacted with alarm.
The escalation has been driven by U.S. military strikes on Iranian targets, including military sites on Kharg Island, Iran’s key oil export hub, and Tehran’s vow to keep the critical Strait of Hormuz effectively closed amid the conflict between U.S./Israel and Iran.
The United States launched airstrikes on March 13, 2026, targeting more than 90 Iranian military positions on Kharg Island, a Persian Gulf port through which as much as 90 percent of Iran’s crude oil exports are processed and loaded for shipment. Although energy infrastructure was reportedly not directly hit, the strikes heightened fears of broader disruption to oil exports from the region.
Iran has responded with threats and military actions across the region, prompting the effective shutdown of tanker traffic through the Strait of Hormuz, the narrow waterway that links Persian Gulf producers to international markets and normally channels about 20 percent of global seaborne crude oil. With commercial shipping sharply curtailed or paused due to security risks, markets have repriced energy risk premiums sharply higher.
In early March 2026, the conflict has slashed shipping flows through the strait by as much as 70 percent, driving up freight costs, war-risk insurance premiums, and logistical uncertainty. Because many fertilizers and crude oil shipments are exported from the Gulf and travel through Hormuz, markets have tightened, and key energy price benchmarks have risen sharply within days of the disruption.
Norway’s largest fertilizer producer and other analysts have warned that a prolonged blockage could seriously reduce global crop yields and threaten food supplies, especially in countries that cannot outbid richer nations for scarce resources.
The disruption to Gulf oil exports has already had significant knock-on effects. Flows through the Strait of Hormuz have plunged to near-standstill levels as shipping companies and insurers reroute tanker traffic via much longer passages around Africa or avoid the region entirely.
Analysts estimate that the absence of normal transit may leave millions of barrels per day of oil, and significant natural gas and product volumes, out of international markets, tightening global supply at a time when spare production capacity is limited. With these physical disruptions, Brent crude prices have climbed sharply, gaining more than 40 percent since the conflict began, and briefly trading above $106 per barrel, reflecting a high level of geopolitical risk priced into global energy markets.
In an extraordinary move, members of the International Energy Agency (IEA) agreed to release 400 million barrels of oil from emergency reserves, the largest such coordinated release in the agency’s history, in an effort to blunt the price surge and support supplies, especially in Asia and other major consuming regions.
This release supplements smaller moves by individual countries and seeks to temper some of the upward price pressure caused by the supply shock. Despite these actions, markets remain highly sensitive to further developments, as the pace of reserve releases may not fully offset the scale of exports blocked by the conflict, and investors remain wary of open-ended escalation in the Gulf.
The effects of sustained energy price pressure are already rippling through global financial markets and broader economies. Higher crude and refined product prices, including diesel and gasoline, are translating into upward pressure on consumer and business fuel costs, which can feed into broader inflation measures in major economies. Retail gasoline prices in the United States and fuel costs across Asia have risen as a result.
Equity markets have responded unevenly; in some trading sessions, major stock indices have fallen in response to heightened geopolitical risk and potential economic slowdown, while energy stocks and related sectors have outperformed amid higher commodity prices. Prolonged disruption in Gulf exports, especially if accompanied by broader regional escalation, could constrain global economic growth, as energy input costs weigh on industrial activity and consumer spending. Many emerging economies that are net energy importers are particularly vulnerable to such price shocks.
The Strait of Hormuz is one of the world’s most consequential maritime chokepoints. Running roughly 21 miles at its narrowest point between Iran and Oman, it serves as a gateway for millions of barrels of oil every day destined for Asia, Europe, and beyond. Its importance to global energy flows means that even temporary disruptions can rapidly magnify risk premiums and inject volatility into oil futures markets.
In the current conflict, Iran’s leadership has indicated a willingness to maintain a blockade of the strait if hostilities continue and if U.S./coalition naval presence attempts to reopen the route. That stance has added to market uncertainty and made it difficult for traders and policymakers to forecast when, or if oil exports might return to prior levels.
Meanwhile, U.S. officials have reportedly been in talks to organize a coalition of partner nations to escort commercial shipping through the region, a strategy aimed at restoring some degree of commercial flow and breaking the effective chokepoint. However, details including participating countries, timing, and naval assets involved have not yet been fully confirmed.
The current Middle East conflict and its repercussions for energy markets represent one of the most significant supply disruptions since the oil shocks of the 1970s. With Brent crude near multi-year highs, emergency releases from strategic reserves underway, and no clear end in sight to the Strait of Hormuz impasse, global markets are confronting a range of possible scenarios, from near-term stabilization if conflict eases, to prolonged volatility if shipping remains curtailed.
For consumers, businesses, and policymakers alike, the key variables will be how long the shipping disruption lasts, the effectiveness of coordinated reserve releases, and the political resolution of the conflict itself. Until those are resolved, oil markets and energy-dependent economies will likely continue to experience heightened uncertainty and price risk.
