Escalating conflict around Iran and the effective closure of the Strait of Hormuz have triggered a sharp spike in energy and freight costs, with knock‑on effects on fertilizer markets and global food inflation. For the potato sector, higher oil, gas, freight and nutrient prices are feeding directly into production, storage, processing and logistics costs, even as some downstream prices remain sticky.
While potato and potato‑starch quotations in parts of Europe have so far remained broadly stable, the war‑driven surge in fuel and fertilizer prices is eroding margins across the chain. Traders, processors and growers now face a structurally higher cost base as long as Middle East shipping remains disrupted and energy markets stay on edge.
Introduction
The 2026 Iran war has turned the Strait of Hormuz into a central flashpoint for global commodity flows. Hormuz normally carries around 20% of global seaborne oil and significant LNG volumes; tanker traffic has fallen sharply since Iran moved to restrict passage, forcing rerouting of crude and gas and pushing up benchmark prices.
Brent crude has climbed well above USD 100/bbl in recent days, with analysts speaking of a war premium of USD 30–40 per barrel, while some scenarios now contemplate prices approaching USD 200/bbl if the strait stays effectively closed. Freight rates for tankers and container ships have jumped as ships avoid the Gulf or price in additional risk, feeding directly into transport and input costs for agriculture.
🌍 Immediate Market Impact
The closure and militarization of Hormuz, combined with attacks on regional energy infrastructure, have produced what the IEA describes as the largest disruption in the history of the global oil market. Oil supply from key Gulf producers has been curtailed, and redirecting flows via alternative routes such as Saudi Arabia’s East‑West pipeline to Yanbu has only partially offset lost capacity.
Higher oil and LNG prices are lifting diesel, electricity and bunker fuel costs worldwide. This is pushing up ocean freight rates: spot container prices on main Far East–Europe and Far East–US West Coast routes have risen 20–25%, and tanker and LNG day rates have hit record levels. For input‑intensive crops such as potatoes, the impact is felt through higher fuel for fieldwork and irrigation, more expensive cold storage and processing, and rising transport costs on export lanes.
📦 Supply Chain Disruptions
Shipping lines are adding risk surcharges and rerouting vessels away from the Gulf, increasing voyage times and tying up capacity. Hapag‑Lloyd estimates the Iran war is adding USD 40–50 million per week to its costs via higher fuel, insurance and storage, which it intends to pass through to customers. This is contributing to wider container and bulk freight inflation that affects frozen and dehydrated potato products, seed potatoes and processed starch shipments.
Fertilizer flows are a particular concern for the potato industry. The Gulf region accounts for roughly a quarter to a third of global seaborne fertilizer exports, including urea, ammonia, phosphates and sulfur, much of which usually transits Hormuz. Disruptions to these exports, coupled with higher gas prices, have pushed fertilizer prices up by as much as 40% since the start of the conflict, with nitrogen products especially affected.
India and other major importers in Asia are rushing to diversify supply away from the Gulf, bidding up alternative volumes from North Africa, Russia and other origins. This tightens the global nutrient balance and raises input costs for potato growers in both developed and emerging markets, particularly where farmgate prices cannot adjust quickly.
📊 Commodities Potentially Affected
- Crude oil and refined fuels – Directly supported by restricted Hormuz flows and refinery attacks, lifting diesel, gasoline and bunker costs across all agri supply chains.
- LNG and natural gas – Reduced Gulf LNG exports tighten global gas balances, raising power and fertilizer feedstock costs in importing regions.
- Nitrogen fertilizers (urea, ammonia) – High gas prices and shipping bottlenecks through Hormuz have pushed up urea prices by around 50% and driven volatility in ammonia.
- Phosphate and sulfur fertilizers – Supply risks from Gulf exporters and rising freight costs are inflating DAP/MAP and sulfur prices, key for potato nutrition.
- Containerized frozen and dehydrated potato products – Higher container freight rates on Asia–Europe and trans‑Pacific routes increase delivered costs for fries, flakes and granules.
- Potato starch and derivatives – While spot prices in some EU origins remain stable, rising energy and logistics costs threaten margins for processors and could trigger upward price adjustments if pressures persist.
🌎 Regional Trade Implications
Asian fertilizer importers that relied heavily on Gulf suppliers—such as India and other South and Southeast Asian markets—face the greatest short‑term disruption and may need to draw down stocks or pay premiums for alternative cargoes. This could constrain nutrient application rates for potatoes and other crops if price transmission to farm level is severe.
In contrast, fertilizer producers outside the conflict zone, including in North Africa, Russia, Europe and the Americas, stand to benefit from stronger pricing and substitution demand. Exporters of processed potato products in Europe and North America may also gain relative competitiveness if rivals in more energy‑dependent regions see sharper cost escalation.
On the logistics side, ports and corridors that bypass the Gulf—such as Saudi Arabia’s Red Sea outlets, Mediterranean hubs and North American gateways—are absorbing some diverted flows, but at the cost of longer voyages and higher freight. This reinforces regional disparities in delivered prices for imported potatoes, starches and processed goods.
🧭 Market Outlook
In the near term, the key driver for potato‑related costs will remain energy markets and their influence on freight and fertilizer. As long as Hormuz traffic is constrained and attacks on regional infrastructure continue, traders should expect elevated volatility in oil, LNG and nitrogen prices, and persistent risk premiums in freight markets.
Any credible de‑escalation or partial reopening of Hormuz could trigger a sharp pullback in energy and freight benchmarks, easing some pressure on input costs. Conversely, a multi‑hub disruption scenario—combining Gulf chokepoints with further strikes on infrastructure—would raise the risk of a broader supply shock, with stronger spillovers into global food prices.
CMB Market Insight
The 2026 Hormuz crisis underlines how deeply the potato value chain is intertwined with energy, freight and fertilizer markets. Even where finished potato and starch prices have not yet moved, producers and processors are absorbing a rapid increase in operating costs that is unlikely to be temporary if geopolitical tensions persist.
For market participants, risk management now hinges on closely monitoring energy and fertilizer benchmarks, reassessing freight exposure on vulnerable corridors, and securing diversified input and logistics options. In this environment, contract structures that share cost risks along the chain, and strategic stock and sourcing decisions, will be critical to maintaining competitiveness in the global potato sector.
