Agriculture relies on fossil fuels. It’s costing us.
Rising fossil fuel prices, exacerbated by geopolitical conflict in Iran, are driving up fertilizer costs, which in turn increases food prices globally. Microbe-based alternatives are emerging but face limitations.
Intelligence analysis by Gemini 2.5 Flash
The agricultural sector is heavily dependent on fossil fuels, particularly natural gas, for fertilizer production. Recent conflicts, like the war in Iran, have disrupted trade routes and spiked natural gas prices, leading to significantly higher fertilizer costs and contributing to global food inflation. This vulnerability highlights the urgent need for sustainable alternatives.
Imagine the food your plants eat, called fertilizer, is made using a special kind of gas. When there's a war far away, that gas becomes super expensive, like when your favorite toy costs way more than usual. Because the plant food is expensive, farmers have to pay more, and then the food we buy at the grocery store also gets more expensive. Some smart scientists are trying to make new plant food using tiny helpers called microbes, so we don't have to rely on that expensive gas anymore.
Analysis
The intricate link between fossil fuels and agriculture has been starkly exposed by recent geopolitical events, leading to a significant surge in fertilizer prices. Natural gas is not merely an energy source for fertilizer production but also a crucial chemical input for ammonia, a primary ingredient. This dual dependency means that any volatility in natural gas markets, such as that caused by the conflict in Iran, directly translates into higher costs for farmers and, subsequently, consumers.
Strait of Hormuz
The conflict in Iran has had a profound impact on global trade, particularly affecting the movement of fertilizers. Approximately one-third of the world's seaborne fertilizer trade typically transits through the Strait of Hormuz, a vital maritime chokepoint. The effective closure of this strait to commercial traffic due to the conflict has created significant supply chain disruptions, exacerbating the price increases and limiting access to essential agricultural inputs, especially for vulnerable, poorer nations.
Pivot Bio
In response to these challenges, innovative companies like Pivot Bio are developing alternative solutions. Pivot Bio specializes in creating fertilizers using genetically edited microbes that can provide nitrogen to plants without relying on natural gas inputs. This approach offers a potential hedge against the volatile fossil fuel market, allowing farmers to lock in prices and reduce their exposure to energy price spikes. While these microbial products currently replace a fraction of synthetic fertilizers, they represent a crucial step towards decoupling food production from fossil fuel dependency.
CoBank
The long-term outlook for fertilizer prices remains uncertain, with some forecasts, including a report from CoBank, one of the largest US agricultural banks, suggesting high prices could persist through at least 2028. This extended period of elevated costs is partly attributed to the lasting damage inflicted by conflicts, such as the war in Iran, which has affected or shut down 31 ammonia plants in the Middle East, in addition to 20 plants damaged in Russia in recent years. Such sustained high prices pose a significant threat to farmers' already thin margins and contribute to broader food inflation, emphasizing the systemic vulnerability of the current agricultural model.
Key points
- Rising fossil fuel prices, particularly natural gas, are directly increasing fertilizer costs due to its use as both an energy source and chemical input.
- The conflict in Iran has disrupted global trade, closing the Strait of Hormuz to commercial traffic and affecting one-third of global seaborne fertilizer trade.
- Fertilizer prices, like urea, have climbed significantly, reaching levels not seen since 2022, with forecasts suggesting high prices could persist until at least 2028.
- Companies like Pivot Bio and Switch Bioworks are developing microbe-based fertilizers as an alternative to reduce reliance on fossil fuels.
- High fertilizer costs are squeezing farmers' already thin margins and contributing to higher food prices for consumers.
The development and scaling of microbe-based fertilizers, as pioneered by companies like Pivot Bio and Switch Bioworks, offer a promising path to reduce agriculture's reliance on fossil fuels. This innovation could stabilize fertilizer costs, mitigate the impact of geopolitical conflicts on food prices, and contribute to a more sustainable and resilient global food system.
Continued geopolitical instability and the long-term damage to fertilizer production facilities in key regions could keep fertilizer prices elevated for years, potentially through 2028. This sustained pressure on farmers' margins could lead to higher food prices globally, disproportionately affecting poorer countries and exacerbating food insecurity.
Market signals
- NG Geopolitical conflict in Iran and trade disruptions through the Strait of Hormuz have caused natural gas prices to spike, as it is a key input for fertilizer production.
- Urea Fertilizer Fertilizer prices, particularly for urea, have climbed significantly due to increased natural gas costs and trade disruptions, with forecasts suggesting high prices through 2028.
