A Landlocked Nation Strangled: Afghanistan's Trade and Aid Lifelines Severed by the Pakistan Border and Strait of Hormuz Closures

Afghanistan's humanitarian and economic crisis has deepened dramatically because the country has, in effect, been placed under a dual blockade. The conflict-driven closure of its border with Pakistan in October 2025 severed the country's traditional eastern trade artery. When commerce and aid were redirected through Iran's Bandar Abbas port, the subsequent closure of the Strait of Hormuz cut off that new lifeline. The result is a compounded catastrophe that has sent transport costs and food prices soaring while emergency nutritional aid for up to 1 million children hangs in the balance .

A Cascade of Closures: How Afghanistan Lost Both Trade Corridors

The blockade is a story of sequential disruption that quickly became a full-blown logistical nightmare.

First, the eastern door slammed shut. The border with Pakistan has been largely closed since mid-October 2025 following deadly clashes between the two countries. This closure is expected to last at least through September 2026, cutting off the primary route through Karachi that historically handled a massive share of Afghanistan's imports, including food and fuel .

The fallback plan then collapsed. In response, Afghan traders and humanitarian agencies, including the United Nations' World Food Programme (WFP), rerouted shipments to Iran's Bandar Abbas port. This was the closest major maritime gateway and the only viable alternative for a landlocked country .

The naval chokepoint sealed the crisis. War in the region effectively shut the Strait of Hormuz, stranding hundreds of ships and their crew, and immediately choking off the Iranian corridor. With the eastern route blocked by a border closure and the western route blocked by war, Afghanistan was suddenly cut off from its two main supply lines .

Humanitarian Fallout: Tripled Costs, Delayed Aid, and Children Turned Away

The practical consequences for humanitarian operations have been swift and severe.

• Aid delivery costs have roughly tripled. The WFP reports that the cost of delivering food to Afghanistan has skyrocketed since the Strait of Hormuz closure began .
• Transit times have been extended by three weeks. It now takes about three weeks longer for food shipments to reach the country, a delay that further strains a fragile food system .
• Lifesaving nutrition for 1 million children is at risk. WFP's operations, which include therapeutic foods for malnourished mothers and children and fortified biscuits for schoolchildren, are directly affected. The UN has warned that aid for up to 1 million children is now threatened .
• A new, far longer supply route has been forged. After losing both the Pakistan and Iran corridors, the WFP was forced to reroute supplies overland through seven countries—including Saudi Arabia, Turkey, Georgia, and Turkmenistan—from Dubai to Afghanistan .
• The most vulnerable are already being turned away. Due to acute supply shortages, some humanitarian facilities on the ground have been forced to turn away malnourished women and children .

WFP Afghanistan director John Aylieff summarized the human cost starkly: “Afghan children today are going hungry as a result,” warning that many could die if the disruptions continue .

Economic Shockwaves: A 20% Jump in Food Prices and a Crippled Private Sector

The dual blockade has not only throttled humanitarian aid; it has also injected severe inflation into the commercial economy.

• Food prices have surged by roughly 20%. The WFP directly attributes this sharp increase across Afghanistan to the Strait of Hormuz crisis .
• A wider energy and fertilizer shock is unfolding. The Hormuz closure took roughly 20% of the world's seaborne oil offline, triggering a global energy shock that pushed up fuel and fertilizer prices and made food production and transport even more expensive .
• The business community describes the situation as devastating. Losing both major trade routes simultaneously has been disastrous for import-dependent sectors, including food, medicine, and construction materials. The simultaneous loss has also crippled Afghan exports like dried fruits, carpets, and textiles, which depended on both corridors to reach global markets .

A Permanently Fragile State: The Outlook Despite a Reopening

The situation remains deeply precarious, even with a critical but limited diplomatic development.

The Strait of Hormuz reportedly reopened in April 2026 following a temporary ceasefire, but the International Rescue Committee (IRC) has cautioned that the disruption's effects "will not be quickly reversed" . Weeks of backlogs are likely to take months to clear. Meanwhile, the Pakistan border remains closed, perpetuating a one-corridor reality for a country that desperately needs both. The United Nations notes that logistics costs have risen by around 20%, and up to half of humanitarian commodities are at risk of pipeline breaks . Afghanistan's supply chain may have survived the immediate shock, but it remains in a state of extreme and enduring fragility.
