How Europe's Farmers Are Already Feeling the Iran War — Before It Even Started in Their Fields

European farmers are being hit by the Iran war from two directions simultaneously: soaring fuel costs and spiking fertiliser prices. Here is the full picture.

The Iran war arrived in European agriculture before most European farmers even knew its name. The sequence of cause and effect runs through several steps, each invisible to the consumer who buys a cucumber in a supermarket without thinking about the supply chain behind it.

Step one: US-Israeli strikes on Iran begin February 28. Step two: oil prices surge from approximately $70 to $122 per barrel over four weeks as Hormuz restriction removes supply. Step three: diesel prices at German and French agricultural fuel depots rise 25-30 percent in the same period. Step four: fertiliser prices, which track natural gas prices because nitrogen fertiliser production is extremely energy-intensive, surge by 35-40 percent from their already elevated March levels. Step five: European farmers, who had locked in fuel and fertiliser purchasing contracts for the spring planting season months in advance, find that their input costs have increased dramatically relative to the prices they can charge for their output.

The timing is brutal. Spring is when European farmers spend the most on inputs — fuel for field preparation and planting equipment, fertiliser for application before and during growth — and when their cash flow is at its most negative, having not yet received income from the harvest that is months away. A 30-40 percent increase in fuel and fertiliser costs during this window translates directly into either higher debt (borrowing more to cover the gap) or lower investment (buying less fertiliser, which reduces yield).

French agricultural unions, already in a combative mood following the farmer protests of early 2026, have called for emergency meetings with the agriculture ministry and have threatened further protests if support measures are not announced within the week. German agricultural organisations have published detailed analyses showing that at current input prices, large categories of crop production — particularly winter wheat and sugar beet — are at or below the break-even cost for many producers.

The European Commission's emergency agricultural working group, which has never been particularly fast-moving, is under pressure to activate reserve funds and provide bridging support before the planting season reaches the point of no return.
