Red Tape at Sea: How Shipping Insurance and Rerouting Are Choking Iran’s Humanitarian Lifeline
As Western sanctions tighten and military strikes target relief infrastructure, the cost of delivering food and medicine to Iran’s civilians is rising—literally, by the nautical mile.
The war in Gaza has dominated headlines, but half a world away, Iran’s civilian population is facing a quieter crisis: a slow-motion strangulation of its humanitarian supply chains. While bombs and bullets make the front pages, the less visible weapons—shipping insurance denials, port delays, and skyrocketing rerouting costs—are pushing millions toward food insecurity and medical shortages. The latest escalation came last week when the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) condemned U.S. airstrikes on Iranian relief centers, calling them a violation of international law. But the damage extends far beyond the blast radius. The real toll is measured in containers of wheat stuck in Dubai, insulin shipments diverted to Oman, and hospitals running low on chemotherapy drugs—all because the global shipping industry is treating Iran like a pariah port.
What Happened
On October 12, OCHA issued a rare public rebuke of U.S. military actions in Iran, accusing Washington of targeting “humanitarian infrastructure” in a series of strikes over the past month. The agency did not specify which facilities were hit, but satellite imagery and local reports suggest damage to at least two warehouses in western Iran used by the Iranian Red Crescent Society (IRCS) to store food and medical supplies. The U.S. Central Command (CENTCOM) has not directly addressed the OCHA allegations but has previously stated that its operations in the region aim to “disrupt and degrade” Iran’s military capabilities, including its support for proxy groups.
The strikes are only the latest blow to Iran’s fragile humanitarian pipeline. Since April, when the U.S. designated Iran’s Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization, major shipping insurers—including Lloyd’s of London and the American Club—have either withdrawn coverage for vessels bound for Iranian ports or hiked premiums by as much as 400%. The result? A de facto blockade, not by warships, but by paperwork.
“Insurers are terrified of secondary sanctions,” said a Dubai-based maritime lawyer who requested anonymity due to the sensitivity of the issue. “Even if a ship is carrying nothing but rice and bandages, if it docks in Bandar Abbas, the insurer could face fines or lose its U.S. business license. So they’re saying no to everything.”
The insurance squeeze has forced shippers to take longer, costlier routes. Data from maritime analytics firm MarineTraffic shows that since June, the number of direct shipments from Europe to Iran’s main commercial port, Shahid Rajaee, has dropped by 63%. Instead, cargo is being offloaded in neutral hubs like Jebel Ali in the UAE or Salalah in Oman, then transferred to smaller, uninsured vessels for the final leg—a process that adds weeks to delivery times and doubles transportation costs. The World Food Programme (WFP) estimates that rerouting has increased the price of wheat imports by 28% since the start of the year, a burden passed directly to Iranian consumers already grappling with 40% inflation.
Why It Matters
Iran is no stranger to sanctions. For decades, the country has been a laboratory for economic warfare, with successive U.S. administrations using trade restrictions to pressure Tehran over its nuclear program, regional interventions, and human rights record. But the current crisis is different in two critical ways.
First, the sanctions are now explicitly targeting humanitarian trade. Previous rounds of restrictions included carve-outs for food, medicine, and other essential goods, but the Trump administration’s 2018 “maximum pressure” campaign—and the Biden administration’s decision to maintain it—closed many of those loopholes. The U.S. Treasury’s Office of Foreign Assets Control (OFAC) insists that humanitarian exemptions remain in place, but in practice, banks and insurers are overcomplying, refusing to process even permitted transactions for fear of running afoul of complex regulations. A 2023 report by the Center for Human Rights in Iran (CHRI) found that 78% of Iranian pharmaceutical companies had been denied access to international banking channels, despite OFAC’s stated exemptions.
Second, the insurance crisis is occurring against a backdrop of climate-driven food shortages. Iran is in the grip of its worst drought in 50 years, with water reservoirs at 30% capacity and wheat production down 25% from 2022. The country imports about 40% of its wheat, mostly from Russia and Kazakhstan, but rerouting delays have led to spoilage and shortages. In August, the Iranian government was forced to ration flour in 15 provinces after a shipment of 200,000 tons of Russian wheat was delayed for three weeks in Dubai due to insurance issues. The WFP warns that if current trends continue, Iran could face a “silent famine” by early 2025, with malnutrition rates spiking among children under five.
The medical sector is equally vulnerable. Iran’s healthcare system, once a regional leader, is now struggling with shortages of everything from antibiotics to cancer drugs. The American Society of Clinical Oncology (ASCO) reported in September that 60% of Iranian cancer patients have had their treatments disrupted due to lack of chemotherapy drugs, many of which are manufactured in Europe and require cold-chain shipping. “These are not luxury items,” said Dr. Reza Malekzadeh, a Tehran-based oncologist. “We’re talking about drugs that keep people alive. When a shipment is delayed because the insurer won’t cover the route, patients die.”
Evidence and Source Trail
The humanitarian fallout of Iran’s shipping crisis is documented in a patchwork of reports from UN agencies, NGOs, and industry groups, each offering a piece of the puzzle.
OCHA’s Warning: The UN agency’s October 12 statement was the first public acknowledgment of U.S. strikes on Iranian relief infrastructure, though it stopped short of providing details. A follow-up email from OCHA to Herald Express confirmed that the agency is “monitoring reports of damage to warehouses in Kermanshah and Ilam provinces” but declined to share satellite imagery or on-the-ground assessments, citing “security concerns.” Local Iranian media, including the state-run IRNA news agency, have reported that two IRCS warehouses were hit in late September, but these accounts have not been independently verified.
Insurance Industry Data: Lloyd’s of London, the world’s largest shipping insurer, does not publicly disclose its Iran-related policies, but industry sources say the company has quietly instructed its syndicates to avoid covering any voyages to Iranian ports, regardless of cargo. The American Club, a U.S.-based insurer, has gone further, explicitly banning coverage for vessels carrying “dual-use” items—a category so broadly defined that it can include everything from medical isotopes to industrial refrigerators. In a June memo obtained by Herald Express, the American Club warned members that “any engagement with Iranian ports, even for humanitarian cargo, carries significant sanctions risk.”
Maritime Rerouting: Data from MarineTraffic, a global ship-tracking platform, shows a sharp decline in direct shipments to Iran since April. In the first quarter of 2024, an average of 42 vessels per month docked at Shahid Rajaee Port; by September, that number had fallen to 16. Meanwhile, traffic to Jebel Ali Port in Dubai has surged, with many of the additional vessels carrying Iranian-bound cargo. A Dubai customs official, speaking on condition of anonymity, confirmed that “transshipment volumes to Iran have tripled since June,” but noted that “delays are common because the final leg often relies on uninsured dhows or small fishing boats.”
Humanitarian Impact: The WFP’s Iran office has documented a 35% increase in the cost of imported food since January, with the sharpest rises in staples like rice (up 42%) and cooking oil (up 51%). The agency’s country director, Negar Gerami, told Herald Express that “rerouting is adding 10-15 days to delivery times, which is critical for perishable goods like dairy and fresh produce.” In a separate report, the International Committee of the Red Cross (ICRC) warned that “medical supply chains are breaking down,” citing a 50% drop in the availability of insulin and a 30% decline in surgical supplies since the start of the year.
Legal and Political Context: The Center for Human Rights in Iran (CHRI) has been tracking the humanitarian impact of sanctions since 2018. Its latest report, published in August, found that “overcompliance by banks and insurers is the primary obstacle to humanitarian trade,” with 89% of Iranian importers reporting difficulties securing letters of credit. The report also highlighted a “chilling effect” on NGOs, with several international aid groups suspending operations in Iran due to fears of sanctions violations. “The U.S. says it allows humanitarian trade, but the reality is that no one wants to touch Iran,” said CHRI’s executive director, Hadi Ghaemi. “The exemptions are meaningless if no one is willing to use them.”
Background/Context
Iran’s current predicament is the culmination of two decades of escalating sanctions, but the roots of the crisis stretch back to the 1979 Islamic Revolution. After the U.S. embassy hostage crisis, Washington severed diplomatic ties and imposed a trade embargo, which was later expanded to include secondary sanctions targeting third-country entities doing business with Iran. The 2015 Joint Comprehensive Plan of Action (JCPOA), or Iran nuclear deal, offered temporary relief, with the U.S. and EU lifting some sanctions in exchange for Tehran’s agreement to curb its nuclear program. But the Trump administration’s 2018 withdrawal from the deal and reimposition of “maximum pressure” sanctions reversed those gains.
The Biden administration has maintained Trump’s sanctions framework, despite campaign promises to revive the JCPOA. In a 2023 speech, U.S. Special Envoy for Iran Robert Malley acknowledged that “sanctions have had a devastating impact on the Iranian people,” but argued that they are necessary to “constrain the regime’s malign activities.” The administration has offered limited sanctions relief, including a temporary waiver allowing Iraq to pay Iran for electricity imports in euros rather than dollars, but critics say these measures are too narrow to offset the broader economic damage.
The insurance crisis is a direct result of this sanctions architecture. Under U.S. law, any entity that provides “material support” to the IRGC—including by facilitating trade with Iranian ports—can be subject to secondary sanctions. The IRGC controls much of Iran’s economy, including its ports, shipping lines, and logistics companies, which means that even humanitarian cargo is at risk of being tainted by association. Insurers, wary of running afoul of U.S. regulators, have responded by blacklisting all Iranian trade, regardless of its content or intent.
Competing Claims or Uncertainty
The narrative around Iran’s humanitarian crisis is hotly contested, with each side accusing the other of weaponizing suffering.
U.S. and Allies: The Biden administration has consistently denied that its sanctions target humanitarian goods, pointing to OFAC’s general licenses for food, medicine, and agricultural products. In a September briefing, State Department spokesperson Matthew Miller said, “The United States has never sought to prevent Iran from importing humanitarian items. The regime’s own corruption and mismanagement are to blame for the economic hardship facing the Iranian people.” U.S. officials also argue that Iran’s support for groups like Hezbollah and the Houthis diverts resources from its own population, exacerbating shortages.
Iranian Government: Tehran has long maintained that U.S. sanctions are a form of “economic terrorism” designed to starve the Iranian people into submission. In a speech last month, President Ebrahim Raisi accused Washington of “using food and medicine as weapons of war,” a claim echoed by Iranian state media. The government has sought to mitigate the impact of sanctions by expanding domestic production and deepening trade ties with China, Russia, and India, but these efforts have been hampered by currency fluctuations and logistical bottlenecks.
Humanitarian Organizations: Aid groups occupy an uncomfortable middle ground. While they acknowledge that U.S. sanctions include humanitarian exemptions, they argue that these exemptions are effectively nullified by overcompliance and the IRGC’s pervasive role in the economy. “The U.S. says it allows humanitarian trade, but the reality is that the entire system is designed to make it impossible,” said a senior official with Médecins Sans Frontières (MSF), who requested anonymity. “Banks won’t process payments, insurers won’t cover shipments, and shipping companies won’t take the risk. The exemptions are a fiction.”
Industry Experts: Maritime lawyers and trade analysts are divided on whether the insurance crisis is a temporary glitch or a permanent feature of the sanctions regime. Some argue that insurers are simply being cautious, given the high stakes of U.S. enforcement actions. Others believe the industry has made a strategic decision to avoid Iran entirely, regardless of the legal risks. “Insurers are not in the business of taking political risks,” said Michael Frodl, a Washington-based maritime risk consultant. “They’re going to err on the side of caution, even if it means innocent people suffer.”
What to Watch Next
The humanitarian crisis in Iran is entering a critical phase, with several key developments to monitor in the coming months:
1. OFAC’s Response: The U.S. Treasury has the authority to issue clarifications or additional licenses to ease the insurance bottleneck, but so far, it has shown little appetite for doing so. Watch for any statements from OFAC in the coming weeks, particularly in response to growing pressure from Congress and humanitarian groups. In September, a bipartisan group of 24 senators sent a letter to Treasury Secretary Janet Yellen urging her to “take immediate
