Humanitarian Logistics Under Conflict: The Impact of the Iran–U.S. War on Aid and Supply Chains
Humanitarian logistics, maritime disruption, and supply-chain resilience Humanitarian logistics becomes especially critical when conflict disrupts the systems used to move food, medicine, fuel, shelter materials, and other essential supplies. The ongoing Iran–U.S. war has created a complex logistics environment across the Middle East, with consequences extending well beyond the immediate conflict zone. The disruption of maritime routes, regional airspace, fuel markets, ports, and transportation corridors is creating additional challenges for humanitarian organizations. The effects are not limited to Iran and neighboring countries. Humanitarian supply chains operating across the Middle East, Africa, and other vulnerable regions can also face higher transportation costs, longer lead times, and reduced access to critical supplies. As of October 2026, the Strait of Hormuz remains one of the most important logistics concerns. The International Maritime Organization has confirmed 93 incidents involving commercial shipping in the Strait of Hormuz and the wider Middle East as of October 6, while recent attacks on tankers have increased maritime security risks. For humanitarian organizations, this raises an important question: How can essential supplies continue moving when the transportation infrastructure itself becomes part of the crisis? Figure 1. Humanitarian logistics under conflict: maritime routes, ports, transport infrastructure, and relief supply chains. What Is Humanitarian Logistics? Humanitarian logistics is the planning, coordination, transportation, storage, and distribution of goods and resources required to support people affected by disasters, conflict, displacement, and other emergencies. Unlike commercial supply chains, humanitarian logistics often operates under extreme uncertainty. The objective is not simply to minimize cost. The objective is to deliver the right supplies to the right place at the right time under difficult and rapidly changing conditions. That makes humanitarian logistics particularly vulnerable when transport corridors, ports, airports, fuel supplies, or border crossings are disrupted. Figure 2. A typical humanitarian supply-chain flow from sourcing and procurement to final distribution to affected communities. How the Iran–U.S. War Is Affecting Humanitarian Supply Chains The conflict has created a combination of direct and indirect logistics disruptions. The UN humanitarian system has reported that the consequences of the regional crisis include disruptions to transportation corridors, airspace, ports, border crossings, and fuel supply chains. These disruptions have affected humanitarian operations across several countries and regions. The International Rescue Committee also reported that the closure of the Strait of Hormuz and regional airspace restrictions were affecting humanitarian supply chains, including cargo flights, staff movements, nutrition supplies, medical supplies, and emergency assistance. 1. Longer transportation routes: When a normal shipping route becomes unsafe, humanitarian organizations may have to reroute cargo. Every additional logistics stage introduces another potential point of failure. 2. Higher transportation costs: Fuel prices, vessel availability, insurance premiums, security requirements, and longer routes can all increase logistics costs. 3. Longer lead times: Ports, airspace, border crossings, fuel availability, security conditions, and carrier decisions can all delay shipments. The Strait of Hormuz: A Critical Logistics Chokepoint Figure 3. Container ports and maritime transport become strategically important when a major shipping corridor is disrupted. The Strait of Hormuz is one of the world’s most strategically important maritime chokepoints. Its importance extends beyond energy markets. When maritime traffic through a major chokepoint becomes disrupted, the consequences can spread across energy, transportation, manufacturing, food, and humanitarian operations. On October 7, Reuters reported that attacks and attempted attacks on tankers in the Strait of Hormuz during the previous week reached their highest level since the war began. Maritime security sources and the Joint Maritime Information Center identified at least 12 incidents involving oil, LNG, and LPG tankers between September 28 and October 5. The IMO’s incident database listed 93 confirmed incidents as of October 6. This does not mean that all maritime trade has stopped. Oil continues to move through and around the region, but the cost, complexity, and risk of moving it have increased substantially. Reuters reported that crude exports through Hormuz had recovered to approximately 14.2 million barrels per day, around 80% of pre-war levels, while freight and insurance costs remained elevated. The problem is increasingly not simply whether the product is available, but whether the product can be transported safely, affordably, and reliably. That is a logistics problem. Figure 4.

Documentary-style view of medical and humanitarian cargo handling, illustrating the physical operations behind emergency supply chains. Fuel is one of the hidden foundations of humanitarian operations. Humanitarian organizations need fuel to operate trucks, ambulances, generators, refrigeration systems, warehouses, water pumps, communication systems, field offices, and emergency equipment. If fuel becomes expensive or difficult to obtain, the effect can spread throughout the entire humanitarian supply chain. The International Rescue Committee warned that rising fuel and energy prices were increasing operational costs for humanitarian programs following the disruption of regional transport routes. Food Supply Chains Are Also Vulnerable Food is another major concern. Modern humanitarian food supply chains depend on international transportation networks. Food may be purchased from international suppliers, transported to a regional hub, stored in warehouses, moved through ports, transported across borders, delivered to local distribution centers, and finally distributed to affected communities. A disruption at any stage can delay the entire process. Conflict-related energy and transportation disruptions can also affect fertilizer markets, agricultural production, food prices, and transportation costs. Medical Supply Chains Face Even Greater Pressure Medical logistics is particularly sensitive to delays. Some medical products require temperature-controlled transportation, refrigerated storage, specialized packaging, short delivery windows, reliable electricity, and strict inventory controls. Vaccines and certain medicines may require cold-chain management throughout transportation. A disruption in electricity or fuel can therefore become a medical supply-chain problem. A shipment that arrives late may become unusable. Airspace Closures Add Another Layer of Complexity Humanitarian logistics does not depend entirely on ships. Air freight is often used when speed is more important than transportation cost. Medical
