World's Second-Largest Rice Exporter Was Paralyzed by the War
Vietnam is the world's second-largest rice exporter. But soaring energy prices, triggered by the US-Iran war, have forced the country to cut production. Even with a temporary ceasefire, the world remains deeply worried about food supplies.
Captains speak of diesel prices doubling — with increases potentially larger and longer-lasting than after Russia's 2022 invasion of Ukraine. Dockworkers and forklift operators fear they may soon need new jobs. Fuel and fertilizer shortages from the Middle East have already crippled this agricultural powerhouse, and the outlook for the next planting season is grim, regardless of how the war unfolds.

A Fertile Land Under Siege
The plight of Vietnam's Mekong Delta reveals how this war — despite any announced truce — continues to directly challenge global food supplies, triggering a cascade of long-term consequences. Farmers are still captive unless tankers laden with crude-mega-shiploads every four days can come safely and Iran keeps the promise it made not to block Hormuz.
Healthy yields rely on proper nutrition, so if they are undernourished, global food prices will soar. The vise squeezing world farm output is not only caused by high fossil fuel prices, but also impoverished half-dozen of Asian countries that cannot afford minerals--in particular right away when seedlings desperately need them. Before it is too late, the price and scarcity of fertilizers must be solved.
Economically speaking, it can tackle tomorrow's problems today: oil and the world's poor soil. Asia depends heavily on the Middle East for both oil and fertilizer. The Mekong Delta and its 19 million residents-in theory if not fact-are difficult to disturb. But even before this war, climate change was already driving saltwater into fertile land, setting off anxiety nearly everywhere. At present the oil crisis has hit like a hammer blow, adding further disillusionment with a resource once known as "black gold," but increasingly feels more akin to fate.
Fuel Rationing and Impossible Choices
Fuel rationing began within a week of the war's outbreak. Vietnam lacks substantial fuel reserves, so resource allocation has become a zero-sum game. Conflict between different sectors is inevitable, presenting the nation with an impossible dilemma.
In the struggle for scarce resources, who wins? Urban residents? Manufacturing companies? Or the Mekong Delta — the vast plain that relies on pumped irrigation to export 8 million tonnes of rice, 4 million tonnes of fruit, and nearly 2 million tonnes of seafood every year?
The Mekong Delta spans Vietnam's southern tip and is larger than the Mississippi River Delta. A capillary-like irrigation network crisscrosses the land, where shrimp, poultry, citrus, durian, and rice all grow side by side. Since the war began, the cost of transporting everything — including water and fertilizer — has soared. And no one knows whether the nations involved in peace talks can truly deliver stability.
Ripple Effects Across Asia
Stagnation is rare in Vietnam. After fifty years of brutal war and subsequent famine, the country has developed remarkable momentum. Following the pandemic, farmers bought drones for seeding to reduce gathering of seasonal workers. But agricultural economics research shows that uncertainty kills enterprise. The Mekong has not been spared.
About 90% of Vietnam's rice exports come from the Mekong Delta, destined primarily for the Philippines, but also for Africa and the United States. Normally.
In these abnormal times, buyers are hesitant. Shipping delays of 10 to 15 days have become routine as carriers slow their engines to save fuel. Basmati rice from India destined for the Middle East cannot pass through the Strait of Hormuz. In the Philippines, wholesalers are unsure when they will have enough diesel to transport imported goods.
A Strange Paradox: Falling Wholesale Prices, Rising Costs
The result is a glut of rice across Asia, creating a short-term paradox: wholesale prices are falling while production costs are rising. After a year of good harvests, traders — seeking to hedge against future risks — have lowered the prices they offer to farmers.
Food economists say that even if this suppresses inflation for now, it may not last. They expect sharper price increases for crops that are difficult to stockpile, such as vegetables.
Complex systems tend to produce wicked problems. Even if a lasting peace is eventually achieved, the consequences of the US-Iran war could have long-term effects on agriculture. The world's rice bowl remains under threat, and no ceasefire alone can replant a single grain.
