Middle East Conflict Strains Global Economy as Supply Risks Mount

The spillover effects of the U.S.–Israel–Iran conflict are increasingly extending beyond financial markets into real-world production and consumption, with disruptions emerging across aviation, agriculture, and manufacturing. From tightening jet fuel inventories in Europe to fertilizer shortages ahead of peak planting seasons and rising constraints on industrial raw materials, analysts say global economic risks are accumulating as key pressure points converge.

Economists describe the current environment as one that has effectively 'tightened the warning clock' on the global economy, with risks intensifying as multiple critical timelines approach.

Aviation Fuel Tightening Raises Risk Of Flight Disruptions In Europe

In Europe, where summer typically marks peak travel season, airlines are now facing rising risks of flight cancellations due to surging jet fuel prices and tightening inventories.

International Energy Agency Director Fatih Birol said in a recent media interview that Europe's aviation fuel reserves may be 'down to around six weeks,' warning that if Middle East disruptions to oil supply persist, many flights could soon be cancelled.

According to industry data and model estimates cited by the agency, Europe remains highly dependent on Middle Eastern jet fuel supply. Under current inventory conditions:

• If 75% of Middle Eastern imports can be replaced, European jet fuel stocks could fall to critical levels — below 23 days — by August

• If only 50% can be replaced, inventories could reach critical thresholds as early as June

Once stockpiles fall below 23 days, some airports are expected to experience direct fuel shortages, leading to flight cancellations. Some European countries are already reporting aviation fuel inventories below 20 days.

The International Air Transport Association has warned that widespread cancellations linked to fuel shortages could emerge as early as late May. Barclays analyst Andrew Lobbenberg also expects European carriers to reduce flight schedules between May and July due to fuel constraints.

Rystad Energy analyst Janiv Shah said European jet fuel inventories are at their lowest level in three years. He noted that weaker supply conditions and rising prices are particularly impacting low-margin short-haul routes, while low-cost carriers face additional pressure due to limited fuel hedging strategies.

Fertilizer Supply Strain Raises Risk Of Food Inflation Cycle

In agriculture, analysts warn that the conflict is triggering a 'compound crisis' by disrupting fertilizer transport routes, tightening fuel availability for farm equipment, and increasing volatility in agricultural trade and financial markets.

Roughly one-third of global fertilizer trade passes through the Strait of Hormuz, making supply chains highly sensitive to regional disruptions.

According to World Bank commodity data, urea — the most widely used nitrogen fertilizer — has seen a sharp price increase since the conflict began. Average international prices rose to about $726 per ton in March, up significantly from around $472 in February.

Agricultural behavior is already shifting in response:

• United States Department of Agriculture data shows U.S. farmers plan to reduce corn planting acreage by 3% in 2026, shifting toward soybeans, which require less nitrogen fertilizer

• In Argentina, some farmers are moving away from wheat toward barley and oats due to high upfront fertilizer costs

The Food and Agriculture Organization of the United Nations says global food stocks currently provide a partial buffer against immediate shocks, but warns that risks are building.

Analysts expect the main agricultural impact to emerge with a delay due to planting cycles. With the global planting season running from April to June, disruptions in the first half of the year could lead to a significant decline in output in the third quarter.

If conditions do not stabilize, food inflation pressures are expected to materialize more clearly toward late 2026 and early 2027, potentially affecting household food costs globally, particularly in lower-income economies.

Manufacturing Faces Inventory Pressure And Raw Material Shortages

The impact of the Middle East conflict is also increasingly visible in global manufacturing. A recent survey published by Reuters shows that disruptions to maritime and air logistics networks are causing delivery delays and worsening input-cost inflation, weighing on industrial recovery.

In the short term, manufacturers are facing simultaneous increases in energy, transportation, and chemical input costs. As disruptions persist, inventories are being drawn down across supply chains.

Industry norms suggest that most manufacturers hold between several weeks and up to two months of key raw material inventory. If the conflict extends beyond this horizon, companies may be forced to adjust production levels. If it continues for around three months, risks shift from cost inflation toward outright shortages of critical inputs and components.

Vidya Mani, a supply chain expert and associate professor at the University of Virginia, said damage to LNG-linked infrastructure in Qatar has contributed to severe helium shortages. Helium is a critical input in semiconductor manufacturing, medical technologies, and aerospace industries.

Mani noted that manufacturers using helium typically maintain only about two months of inventory. If supply conditions do not improve, production of products ranging from automotive chips to mobile devices could face constraints.

Oxford Economics also warned that helium shortages could delay construction of artificial intelligence data centers, potentially leading firms to scale back investment plans.

Separately, aluminum supply risks are also emerging. Gulf countries account for roughly 9% of global aluminum production, and prices have climbed to a more than four-year high due to supply disruptions. Analysts say tighter aluminum availability could affect industries ranging from packaging to automotive manufacturing.

Systemic Risk Building Across Global Economy

Viewed over a longer horizon, analysts say inflationary pressures linked to the conflict could erode global purchasing power and slow recovery momentum in several economies.

While different sectors and regions are expected to experience impacts at varying speeds, the broader trend points to a shift from localized disruptions toward a more systemic risk environment across global manufacturing, agriculture, and transport networks.
