How Does the War With Iran Impact Agriculture in 2026?

Prices, Trade & Farmland

By Nolan Sampson

I’m Nolan Sampson, a farmland real estate agent and farm manager serving clients across Indiana and Michigan. My work centers around helping landowners and operators make sound, long-term decisions—whether that’s managing farmland, navigating leases, or evaluating buying and selling opportunities.

In today’s environment, those decisions are being shaped by something far bigger than local markets: global conflict. The 2026 war involving Iran is already having real, measurable impacts on agriculture here in the Midwest. From input costs to commodity prices and ultimately farmland values, this situation is worth understanding.

Let’s break down what’s happening—and what it means for farmers, landowners, and investors.

The Big Picture: Why This War Matters to Agriculture

The Iran conflict has disrupted one of the most important chokepoints in global trade: the Strait of Hormuz. This region is critical not just for oil, but for fertilizer and energy inputs that agriculture depends on.

When that system gets disrupted, agriculture feels it quickly—and often painfully.

The result in 2026:

• Higher fertilizer prices

• Increased fuel and input costs

• More volatile commodity markets

• Uncertainty in global trade

For Midwest agriculture, this is not theoretical—it’s already showing up in balance sheets.

Fertilizer Prices: The Immediate Pressure Point

If there’s one area where this conflict hits hardest, it’s fertilizer.

• Fertilizer prices have surged as much as 40% in 2026 due to supply disruptions.

• Roughly one-third of global fertilizer supply moves through the Strait of Hormuz, making it highly vulnerable.

• Nitrogen prices have jumped dramatically, in some cases nearly doubling from prior levels.

From a farm management standpoint, timing matters:

• Farmers who pre-purchased inputs are relatively protected

• Those buying in-season are absorbing significantly higher costs

What this means:

• Pressure on margins, especially for corn-heavy operations

• Potential shift toward lower-input crops like soybeans

• Increased importance of cost control and planning

This is where strong farm management becomes critical—input decisions today will directly impact profitability this fall.

Energy & Fuel Costs: The Hidden Multiplier

Fertilizer isn’t the only issue. Energy prices are rising as well.

• Oil prices surged significantly following the conflict

• Fuel, drying, transportation, and chemical costs all increase alongside energy

And here’s the key: energy drives fertilizer production. Up to 70% of nitrogen fertilizer cost is tied to energy inputs.

So when energy rises, it compounds everything.

On the farm:

• Higher diesel costs for planting and harvest

• Increased trucking and basis pressure

• Elevated grain drying costs

This is squeezing profitability from both sides—higher costs and uncertain revenues.

Commodity Prices: A Mixed Outlook

You might expect higher costs to automatically lead to higher crop prices—and in some cases, they do.

But the reality is more complicated.

Bullish factors:

• Reduced fertilizer use could tighten supply

• Lower global yields may support grain prices

Bearish factors:

• Global competition (especially Brazil in soybeans) remains strong

• Trade disruptions limit export demand

• Broader economic uncertainty weighs on markets

Bottom line:

We’re in a volatile environment, not a guaranteed price rally.

That’s why marketing strategy and risk management matter more than ever.

Global Trade Disruptions: The Bigger Risk

The Strait of Hormuz isn’t just about inputs—it’s also about trade.

• Fertilizer, fuel, and agricultural goods all rely on global shipping routes

• Disruptions increase costs and delays

• Countries may shift sourcing, altering long-term trade relationships

We’ve already seen how quickly trade dynamics can shift in recent years. This conflict adds another layer of uncertainty.

For U.S. agriculture, that means:

• Export demand can change quickly

• Competitor countries may gain market share

• Policy responses could reshape markets

What This Means for Farmland Values

Now let’s bring this back to what I focus on every day—farmland.

Despite all this volatility, farmland historically behaves differently than other assets.

Short-term pressures:

• Higher input costs reduce farm profitability

• Interest rate uncertainty impacts borrowing

• Cash rent margins may tighten

Long-term support:

• Strong balance sheets in agriculture

• Inflation protection characteristics of land

• Limited supply of high-quality farmland

Even in uncertain times, farmland remains a long-term asset class, not a short-term speculation.

Key insight:

Periods like this often separate:

• Well-managed operations from struggling ones

• Strategic buyers from reactive sellers

Farm Management Matters More Than Ever

In an environment like 2026, farm management isn’t just helpful—it’s essential.

The difference between profitability and loss may come down to:

• Input purchasing strategy

• Lease structure and flexibility

• Crop planning decisions

• Marketing timing

This is where I spend most of my time with clients—helping them navigate uncertainty with a clear plan.

Final Thoughts: Uncertainty Creates Opportunity

The war with Iran is a reminder of something agriculture has always faced:

We operate in a global system, whether we like it or not.

Yes, there are real challenges:

• Higher costs

• Market volatility

• Trade uncertainty

But there are also opportunities:

• Stronger commodity prices in certain scenarios

• Strategic land acquisitions

• Improved management efficiencies

The key is being proactive—not reactive.
