Iran Conflict Raises Costs Across Banana Supply Chain, Threatening U.S. Prices

The war in Iran that began in February has pushed up fuel and fertilizer costs across the global banana supply chain, raising the prospect of higher retail prices for the most consumed fruit in the U.S., according to the New York Times and industry officials. Danny Dumas, the president of Del Monte North America, called the situation a "crisis," according to the New York Post. Tom Stenzel, the president of the Banana Association of North America, told The Post that the combination of factors marks a crisis. Banana contract prices remain locked through December, according to the Times. Producers are absorbing the higher costs for now, though it is not known how many grocers will allow prices to rise when those contracts expire, the newspaper reported.

Diesel, Fertilizer and Tariffs Add Pressure to a Low-Margin System

Diesel fuel needed for fast deliveries on refrigerated tankers has risen 70% since the start of the war, the Times reported. The price of banana fertilizer made with natural gas from the Middle East has shot up as well, along with tariffs and a truck driver shortage, according to the report. The fuel pressure is measurable across the broader freight sector. The SONAR DTS.USA Truckstop average retail diesel price stood at $5.18 per gallon on March 20, up from $3.81 per gallon on March 2, according to FreightWaves [1]. One analysis put the national diesel price at about $5.60 per gallon, a rise of more than $2.00 from the $3.55 per gallon recorded a year earlier and in early January 2026 [2]. A single banana packed with potassium can cost as little as 15 cents, but the supply chain that delivers it operates on thin margins, the Times noted. "That system is currently under growing pressure," Stenzel told The Post. The banana business has long been an underappreciated feat of logistics, one that involves transporting a fragile and finicky fruit thousands of miles from the tropics, only to be sold for less than a dollar, according to the Oman Observer [3].

Producers Bear Costs as Contract Deadlines Approach

One producer told the Times that his costs jumped 5% from last year to this year. Costs have risen so much that some proactive farmers have already switched to a different yellow fruit, the report stated. Banana contract prices are set to expire in December, and it is not known how many grocers will let prices go up, according to the Times. Costs were at a six-year high in 2025 at 67 cents per pound, largely attributed to tariffs on imports from Guatemala, Ecuador, Honduras and Costa Rica that have since been lifted. In August, banana costs were 2.2 percentage points higher than the same month last year, the Times reported. The broader produce aisle is also affected. Wholesale prices for berries, limes, tomatoes and other produce are rising, with higher fuel prices from the war with Iran cited as the cause [4]. Rising fuel and fertilizer costs tied to the Iran war are squeezing banana growers in Guatemala and Peru, even as U.S. retail prices stay near 65 cents a pound [5].

El Niño and Panama Disease Pose Longer-Term Risks

The El Niño weather phenomenon is making shipping uncertain, according to the Times. Irregular weather patterns and fungal diseases are usually the main disruptors to the otherwise year-round supply of bananas, according to the Handbook of Banana Production, Postharvest Science, Processing Technology and Nutrition [6]. Panama disease has threatened the Cavendish banana, the world's most popular varietal, for many years, the Times noted. The fungus completely wiped out an earlier banana varietal known as the Gros Michel. The Handbook of Banana Production identifies Fusarium Wilt Tropical Race 4, a fungal disease, as the biggest threat to global banana production, with the potential to disrupt banana production and trade as they are known [6]. Industry officials said the combination of immediate cost pressures and long-term disease risks remains a concern.

Outlook Uncertain as December Contract Expiration Nears

Banana prices remain locked by contracts, but the December expiration could determine whether higher costs reach consumers, officials said. The Times reported that it is not known how many grocers will let prices go up. War-related energy and shipping disruptions are increasing costs for banana producers, while higher fertilizer prices and expiring supply contracts could eventually push up supermarket prices [7]. Banana companies continue to monitor fuel, fertilizer, tariffs, weather and disease, according to industry statements.
