During a pivotal Senate Agriculture Committee hearing on Tuesday, March 12, 2026, lawmakers and expert witnesses converged on a pressing concern: the escalating war in Iran and its immediate, potentially catastrophic impact on American farmers already grappling with unprecedented operational expenses. The testimony underscored a deepening crisis, with agricultural leaders warning that sustained conflict in the Gulf region could push input costs—already deemed "through the roof"—to unsustainable levels, jeopardizing the economic viability of countless farms across the nation.
The Genesis of Crisis: Conflict and a Choked Strait
The current agricultural anxiety is rooted in the recent intensification of geopolitical tensions in the Middle East, culminating in an active conflict in Iran. This escalation, which began in early March 2026, quickly led to a critical development: the closure of the Strait of Hormuz. This narrow waterway, connecting the Persian Gulf with the Arabian Sea and the open ocean, is arguably the world’s most vital oil transit choke point, but its significance extends far beyond energy. It serves as a crucial artery for global trade, particularly for the movement of raw materials and finished products essential for the agricultural sector.
Reports confirm that up to 30 percent of the world’s fertilizer exports, alongside a substantial percentage of other vital raw materials used in fertilizer production, typically transit through the Strait. Its closure has effectively severed a major supply line, creating an immediate and severe bottleneck for global agricultural inputs. The American Farm Bureau Federation (AFBF) President Zippy Duvall articulated the gravity of the situation, stating, "It is a serious time. My phone has been ringing off the hook since last week when the Strait [of Hormuz] was shut down." This sentiment reflects a widespread alarm within the farming community, signaling an impending supply chain shock that threatens to cripple an already strained industry.
Unpacking the Economic Strain: Fertilizer and Fuel
The primary concerns voiced by agricultural groups center on two critical inputs: fertilizer and fuel. Both commodities have seen significant price volatility in recent years, but the current crisis introduces a new, alarming dimension.

Fertilizer: The Lifeblood of Crop Production
Fertilizer is indispensable for modern agriculture, supplying essential nutrients like nitrogen, phosphorus, and potassium that are vital for crop growth and yield. The global fertilizer market is highly interconnected, with major producers and raw material sources often located far from end-users. The closure of the Strait of Hormuz directly impedes the movement of these crucial components. For instance, a significant portion of the world’s ammonia, a key ingredient for nitrogen fertilizers, is produced in Gulf states and must traverse the Strait for export. Similarly, potash and phosphate rock, while sourced from diverse locations globally, often rely on complex shipping routes that are now either disrupted or face increased costs due to rerouting and heightened insurance premiums.
Even before the current conflict, farmers were contending with record-high fertilizer prices. Data from early 2025 showed that nitrogen fertilizer prices had increased by over 200% compared to pre-pandemic levels, with phosphate and potash seeing similar, albeit slightly less dramatic, surges. These increases were attributed to a confluence of factors including rising natural gas prices (a primary feedstock for nitrogen fertilizer), supply chain disruptions, and geopolitical events in other key producing regions. The Iran conflict exacerbates these issues, threatening to push prices further into unprecedented territory. North Dakota Farmers Union President Matt Perdue echoed the sentiments of many, telling senators, "One of the things I consistently hear from neighbors, friends, fellow farmers, and ranchers across the state of North Dakota is input costs are just through the roof." He warned that if the war drives an additional increase, the financial burden would be too great for many farmers, making it impossible to "make it pencil out"—a stark indicator of potential widespread financial distress and even farm closures.
Fuel: Powering the Planting Season
Beyond fertilizer, the soaring cost of fuel poses an equally significant threat, particularly as the spring planting season approaches across much of the United States. Agricultural operations are highly fuel-intensive, requiring diesel for tractors, harvesters, irrigation systems, and the transportation of goods. Any spike in crude oil prices, a direct consequence of instability in a major oil-producing region like the Gulf, translates almost immediately to higher costs at the pump for farmers.
Historical data consistently demonstrates a direct correlation between crude oil price surges and increased operational costs for the agricultural sector. For example, during the 2008 oil price spike, agricultural fuel costs rose by an average of 30-40%, significantly impacting farm profitability. The current crisis, with the Strait of Hormuz—a conduit for approximately 20% of the world’s total petroleum consumption—being shut down, has sent global oil markets into a frenzy. Futures contracts for Brent crude surged by over 15% in the days following the Strait’s closure, indicating widespread market apprehension about future supply. This volatility directly threatens farmers’ ability to afford the fuel necessary to plant and cultivate their crops, potentially leading to reduced acreage, delayed operations, and ultimately, lower yields.
Urgent Calls for Federal Intervention and Policy Shifts
In response to this multi-faceted crisis, agricultural advocacy groups and lawmakers have put forth a series of urgent requests and policy proposals aimed at mitigating the economic fallout for American farmers.
Farm Bureau’s Immediate Demands
The American Farm Bureau Federation (AFBF) has been at the forefront of these efforts, outlining concrete steps it is asking the White House to take. Beyond naval protection for merchant shipping through the Strait to ensure the flow of goods, AFBF’s primary request is for the exemption of critical agricultural inputs, especially fertilizer, from tariffs. This demand is particularly pertinent given ongoing trade disputes and the existing tariff landscape, which has already added to input costs for farmers. For example, a 2025 analysis revealed that tariffs on certain phosphate fertilizers from Morocco and Russia had already contributed to a 15-20% increase in prices for U.S. farmers, even before the current geopolitical crisis. Removing these tariffs, AFBF argues, would provide some immediate relief and prevent further cost escalation.

The Jones Act and Fuel Price Mitigation
To address the burgeoning fuel crisis, AFBF President Zippy Duvall also called upon President Donald Trump to suspend the Jones Act. This federal law, formally known as the Merchant Marine Act of 1920, mandates that all goods transported by water between U.S. ports must be carried on U.S.-built, U.S.-owned, U.S.-crewed, and U.S.-flagged vessels. While intended to support the domestic maritime industry and ensure national security, critics argue that it can inflate shipping costs and limit available capacity, particularly in times of crisis. Waivers to the Jones Act can allow foreign-flagged ships to transport goods, such as oil, between U.S. ports, potentially increasing supply and lowering prices.
President Trump, recognizing the severity of the fuel price situation, indicated on Thursday, March 12, 2026, that his administration plans to grant a waiver to the Jones Act. This move aligns with historical precedents, as waivers have been issued in past emergencies, such as after Hurricanes Harvey and Maria, to facilitate the rapid movement of critical supplies, including fuel. While a temporary measure, such a waiver could help stabilize domestic fuel supplies and offer some respite to farmers ahead of the crucial planting season.
The E15 Debate: A Push for Biofuel and Energy Independence
Throughout the Senate Agriculture Committee hearing, a bipartisan chorus of senators seized the moment to renew calls for year-round sales of E15, a blend of gasoline containing 15 percent ethanol. Lawmakers argued that the situation in Iran bolstered the case for Congress to pass legislation allowing E15 to be sold year-round, citing its potential to boost markets for U.S. corn producers while simultaneously helping to bring down fuel prices.
Historically, federal law has restricted E15 sales during summer months due to concerns about increased smog pollution, particularly related to Reid Vapor Pressure (RVP) regulations. However, federal agencies have issued waivers to override this rule in recent years, especially during periods of high gas prices or supply disruptions. Proponents of E15, including various farm groups, argue that it is a cleaner-burning fuel and that modern vehicle engines are well-equipped to handle the blend. Furthermore, they emphasize that year-round E15 sales would create a more stable and robust domestic market for corn, reducing the nation’s reliance on foreign oil and enhancing energy independence. A 2025 study by the Iowa Renewable Fuels Association estimated that year-round E15 sales nationwide could increase corn demand by an additional 1-2 billion bushels annually, providing a significant economic boost to corn growers.
Market Consolidation and the Defense Production Act
Adding another layer of concern, the farm advocacy group Farm Action sent a letter to the White House on Wednesday, March 11, 2026, warning that the highly consolidated fertilizer market could lead companies to exploit the crisis by raising prices even further. The letter highlighted that just a handful of multinational corporations control the majority of fertilizer production and distribution, creating an environment susceptible to price manipulation during periods of supply shock.
Farm Action urged President Trump to "initiate an immediate review of whether key fertilizer inputs and materials should be designated as scarce or threatened resources under the Defense Production Act if current supply disruptions persist or worsen." The Defense Production Act (DPA), a Cold War-era statute, grants the President broad authority to direct industrial production for national defense. Invoking the DPA could allow the administration to prioritize fertilizer production, allocate resources, and potentially impose price controls or prevent hoarding, thereby safeguarding supply and curbing opportunistic price increases. This call underscores a broader concern within the agricultural community about the impact of corporate consolidation on farmers’ economic leverage and the resilience of the food system.
Broader Implications: Food Security, Supply Chains, and Rural Economies

The escalating crisis in the Gulf and its ripple effects on U.S. agriculture extend far beyond the immediate financial concerns of farmers. The situation poses significant implications for national food security, the resilience of global supply chains, and the economic stability of rural communities.
Food Security and Consumer Prices
Higher input costs for farmers inevitably translate into higher food prices for consumers. As farmers face increased expenses for fertilizer, fuel, and other necessities, they will be forced to either absorb these costs, risking their own profitability and long-term viability, or pass them on through increased commodity prices. This inflationary pressure could exacerbate existing cost-of-living challenges for households across the country. A 2025 analysis by the USDA’s Economic Research Service indicated that a 10% increase in farm-level input costs typically results in a 1.5-2% increase in retail food prices over a 6-12 month period, depending on the commodity. With the potential for much larger input cost surges, the impact on consumer food bills could be substantial, disproportionately affecting low-income households. Moreover, any significant reduction in crop acreage or yields due to prohibitive input costs could jeopardize the stability of the nation’s food supply, raising long-term food security concerns.
Supply Chain Resilience: Lessons Learned
The current crisis serves as a stark reminder of the inherent vulnerabilities in highly globalized supply chains. The reliance on a single, geopolitically sensitive choke point like the Strait of Hormuz for critical agricultural inputs highlights the need for greater diversification and resilience. This event could accelerate discussions about increasing domestic production capabilities for essential agricultural inputs, fostering regional supply networks, and developing strategic reserves of key commodities. The lessons learned from the COVID-19 pandemic, which exposed weaknesses in various supply chains, are now being reinforced by this geopolitical conflict, pushing policymakers and industry leaders to re-evaluate strategies for mitigating future disruptions.
Economic Stability of Rural Communities
The financial health of American farmers is inextricably linked to the economic vitality of rural communities. When farmers struggle with mounting debt and dwindling profits, the ripple effect is felt throughout the local economy. Farm equipment dealers, agricultural service providers, local banks, and small businesses all depend on a thriving agricultural sector. Increased farm bankruptcies or decisions to scale back operations could lead to job losses, reduced investment, and a decline in overall economic activity in many rural areas, exacerbating existing challenges like population decline and limited access to resources. The stress on the agricultural sector thus becomes a stress on the fabric of rural America.
A Critical Juncture for U.S. Agriculture
As the war in Iran continues and the Strait of Hormuz remains closed, the U.S. agricultural sector finds itself at a critical juncture. The convergence of pre-existing high input costs with unprecedented geopolitical instability presents a formidable challenge that demands swift, comprehensive, and strategic responses from both the public and private sectors. The discussions in the Senate Agriculture Committee hearing and the urgent pleas from farm organizations underscore the severity of the situation. The coming weeks and months will be crucial in determining the extent of the impact on American farmers, the stability of food prices, and the long-term resilience of the nation’s food system in an increasingly volatile global landscape. The immediate focus remains on ensuring that the foundational industry of American agriculture can withstand this latest storm, continuing to feed the nation and the world amidst profound uncertainty.
