Rising costs of fertilizer and fuel are pushing British farmers to the brink, threatening food affordability and long-term viability. A farmer in Shropshire has described his industry as being “hammered” by the price spikes, with the potential for significant impacts on consumer costs despite the relatively small impact of commodity prices on everyday items like bread.
Global Instability Drives Price Hikes
The crisis is fueled by volatility in global energy markets, particularly the recent surge in oil prices exceeding $100 a barrel amid tensions in Iran and surrounding Gulf states. These geopolitical factors have sent shockwaves through the agricultural supply chain, where natural gas is a key component in nitrogen fertilizer production (accounting for 60-80% of its cost). Since July 2025, fertilizer prices have jumped by 50% – from £330 to £490 per tonne – adding severe pressure on farm budgets.
Arable vs. Livestock: A Divided Impact
Farmers who grow crops like wheat, barley, and oats (arable farms) may be slightly better positioned, as many secured their fertilizer supplies last year before prices climbed. However, livestock farmers who purchase inputs on demand face the full brunt of the increases.
The situation is worsened by two consecutive poor harvests, leaving farms already struggling to break even. The increased cost of red diesel – a lower-tax fuel used in agriculture – adds another layer of financial strain, with prices rising roughly 50% since before the Iran conflict.
Long-Term Risk and Consumer Effects
The agricultural industry operates on long time horizons: farmers invest two years before seeing returns. This means that every decision carries heightened risk in the current climate. Although commodity prices themselves may not be the primary driver of consumer inflation, the overall cost increases will inevitably be passed down the supply chain.
Farmers are calling for greater transparency in the fuel market, arguing that price spikes are disproportionately rapid compared to declines. The crisis underscores the interconnectedness of global events, agricultural production, and household budgets.
Without intervention or stabilization, these escalating costs could reshape farming practices, reduce output, and further challenge food security in the UK.
