Brent crude has moved above $100 a barrel again, adding another variable to fertilizer cost forecasting as renewed Middle East tension raises concerns about energy flows, shipping and industrial feedstocks. Reuters reported Brent settling at $101.21 on September 9 as attacks around the Gulf and Strait of Hormuz intensified supply concerns.
Oil prices do not directly determine ammonia prices. Nitrogen fertilizer economics are much more closely tied to natural gas, while phosphate production depends on different raw materials and energy inputs.
The important connection is broader. A disruption affecting Gulf oil can also affect gas, LNG, ammonia, phosphates, sulfur and maritime logistics, creating a wider cost and availability shock for fertilizer markets.
The International Fertilizer Association has already identified the Strait of Hormuz as a material risk because it affects both finished fertilizers and the energy and raw materials required to produce them.
The return of Brent above $100 changes the assumptions used by fertilizer buyers when estimating delivered costs.
Crude oil influences transportation, marine fuel and other energy-related expenses throughout the supply chain. Higher oil prices can therefore raise the cost of moving fertilizer even when the underlying fertilizer production cost is unchanged.
The larger concern is the possibility that oil disruption occurs alongside pressure on regional gas and LNG markets.
The Gulf is important to international fertilizer trade because it supplies substantial volumes of urea, ammonia and other fertilizer raw materials. IFA describes the region as central to energy-derived fertilizer supply and identifies urea as the finished fertilizer most exposed to current trade-route risks.
For procurement teams, the result is a broader range of possible delivered costs.
It is important not to treat higher crude prices as an automatic signal for higher natural gas prices.
Ammonia production is primarily gas-linked. Yara's cost model shows natural gas as a major component of ammonia production costs, with a typical consumption rate of about 36 MMBtu of natural gas per tonne of ammonia. Urea production also carries a natural gas-linked process cost and uses ammonia as its principal intermediate.
The connection with oil becomes stronger when a geopolitical event affects several energy markets at once.
If conflict restricts shipping through major waterways, reduces regional energy exports or damages infrastructure, oil, gas and fertilizer markets can all experience simultaneous pressure. That is a risk transmission mechanism rather than a direct oil-to-ammonia pricing formula.
The Middle East has an outsized role in global fertilizer supply, particularly for nitrogen products and important fertilizer raw materials.
IFA's 2026 medium-term outlook identifies the Strait of Hormuz and Red Sea as two trade chokepoints under stress. The organization notes that disruption affects producers, importers, shipping markets, distributors and farmers.
Yara has also reported that the Middle East conflict disrupted global energy and fertilizer markets. Its first-quarter report said the Strait of Hormuz blockage disrupted around one-third of globally traded urea as well as important fertilizer inputs including natural gas, ammonia, phosphates and sulfur.
That makes the current oil rally more relevant to fertilizer forecasting than a simple crude-price movement would suggest.
The key issue is not that fertilizer prices mechanically follow Brent. It is that the same geopolitical event can affect several cost and supply variables simultaneously.
Transportation is one of the clearest channels through which higher oil prices can affect fertilizer costs.
Fertilizer is traded globally in large volumes, often moving by ocean freight from major production centers to importing regions. Higher bunker fuel costs can therefore increase the delivered price even when the producer's ex-works cost remains stable.
The effect can become stronger when shipping routes are disrupted.
Longer voyages, rerouting around maritime chokepoints, higher insurance premiums and tighter vessel availability can all increase logistics costs. Buyers may then face higher delivered fertilizer prices without a corresponding increase in the underlying production cost.
This distinction matters when comparing supplier quotations.
A low FOB price may not remain competitive if freight and insurance costs rise sharply before the shipment reaches the buyer.
Ammonia is particularly sensitive to natural gas availability because gas is a major feedstock and energy source for conventional production.
When gas prices rise, higher-cost ammonia plants can face margin pressure. Producers may reduce operating rates if selling prices do not compensate for higher production costs.
Yara's 2026 reporting illustrates this sensitivity. The company said Middle East disruptions created significant supply shocks across global fertilizer markets, while regional gas and fertilizer price volatility influenced purchasing patterns.
This can create a chain reaction.
Higher gas costs can raise ammonia production costs. Higher ammonia costs can then increase the cost of producing urea and other nitrogen products, particularly in regions where ammonia is purchased as an intermediate.
Urea buyers face both production and logistics exposure.
The production side is connected to ammonia and natural gas costs. The logistics side is affected by shipping fuel, freight availability and trade-route conditions.
Yara's cost framework shows that urea production requires ammonia plus process gas, meaning changes in ammonia economics can flow into urea production economics.
This makes urea particularly important for global procurement planning.
IFA has identified urea as the fertilizer product most exposed to current Gulf trade-route disruption. That exposure reflects the importance of the region in international urea trade as well as the vulnerability of maritime routes.
The fertilizer impact of Middle East tension extends beyond nitrogen.
Phosphate production uses different feedstocks from ammonia, but the sector can still be affected by energy costs, sulfur availability, transportation and regional infrastructure.
IFA specifically identifies phosphates and sulfur among the fertilizer-related raw materials affected by disruption around the Strait of Hormuz.
This means fertilizer buyers should avoid using a nitrogen-only framework when evaluating geopolitical cost exposure.
Different products have different direct feedstock requirements, but their supply chains can converge through shared shipping routes, energy markets and industrial infrastructure.
A single oil-price assumption is becoming less useful for procurement planning.
Buyers can instead model several scenarios around energy and logistics conditions.
A lower-risk scenario could assume continued oil flows, stable gas markets and manageable shipping costs. A moderate-risk scenario could incorporate higher freight rates and regional energy premiums.
A severe-disruption scenario would consider prolonged restrictions around key waterways, tighter gas availability and sustained increases in shipping and insurance costs.
The purpose is not to predict the exact oil price. It is to understand how different combinations of energy and logistics conditions could affect delivered fertilizer costs.
South Asian fertilizer markets deserve close attention because several countries rely on imported energy and fertilizer flows from the Gulf.
IFA notes that fertilizer producers in India, Pakistan and Bangladesh can be exposed to higher feedstock costs or curtailments because of their dependence on imported gas from the Gulf.
For buyers in these markets, the impact of Middle East tension can therefore appear through several channels at once.
Imported fertilizer prices can rise while freight costs increase. Domestic producers can also face higher feedstock costs if regional gas markets tighten.
This creates a more complicated procurement environment than simply tracking international urea prices.
Fertilizer companies are responding to energy volatility by looking for greater geographic and feedstock diversification.
Yara's acquisition of a U.S. ammonia production facility in Texas reflects this broader strategy. The company said the acquisition would diversify its energy exposure and strengthen the competitiveness of its global ammonia production footprint.
The company has also emphasized its ability to optimize ammonia sourcing across markets when regional energy prices change.
For buyers, these developments matter because supplier diversification can improve resilience during regional disruptions.
A producer with multiple manufacturing and sourcing locations may be better positioned to maintain deliveries when one region experiences a feedstock or logistics shock.
Procurement teams should broaden their monitoring beyond crude oil prices.
Important indicators include:
Brent crude: A useful indicator of transportation and broader energy-market pressure.
Natural gas prices: A more direct measure of nitrogen fertilizer production economics.
Ammonia prices: A critical input for urea and other downstream nitrogen products.
Urea prices: A direct benchmark for many agricultural buyers.
Freight rates: Important for calculating delivered fertilizer costs.
Shipping routes: Disruptions can rapidly change voyage times and freight economics.
Gulf export activity: Changes in regional shipments can signal physical supply constraints.
Sulfur and phosphate availability: Relevant for non-nitrogen fertilizer cost exposure.
Monitoring these variables together provides a more reliable view of procurement risk.
The current environment reinforces the importance of calculating landed fertilizer cost rather than relying on benchmark prices alone.
A buyer may see a stable international fertilizer benchmark but still face higher procurement costs because freight, insurance, financing or port charges have increased.
Conversely, a temporary increase in crude prices may have limited impact on fertilizer production if natural gas markets remain stable and shipping routes continue operating normally.
The procurement objective should therefore be to identify which cost component is actually changing.
This approach can prevent buyers from overreacting to headline oil movements while still recognizing genuine supply-chain risks.
Chemical and fertilizer traders can incorporate geopolitical risk into their forward pricing models by separating product, energy and logistics assumptions.
The first layer should estimate production-linked costs, particularly natural gas and ammonia for nitrogen fertilizers.
The second layer should account for freight, insurance and route-specific costs.
The third layer should capture potential risk premiums associated with supply disruption, inventory scarcity and regional price differences.
This structure makes it easier to update a forecast when conditions change.
If oil rises but gas and freight remain stable, the model can reflect a limited fertilizer impact. If oil rises alongside gas, freight and shipping disruptions, the same model can show a much larger potential increase in delivered cost.
The direction of fertilizer costs will depend less on the $100 oil threshold itself than on how long the underlying disruption persists.
Reuters reported that crude flows through the Strait of Hormuz had fallen sharply, while attacks on Saudi energy infrastructure were adding to supply concerns.
For fertilizer markets, the key questions are whether shipping routes remain available, whether Gulf fertilizer exports continue normally and whether gas and LNG markets experience additional disruption.
Yara has already warned that renewed escalation could create additional concerns for fertilizer supply into the next season.
If disruptions remain temporary, fertilizer markets may absorb some of the cost shock through inventories and alternative supply. A prolonged disruption would present a more serious challenge.
Fertilizer buyers can reduce exposure by combining multiple sourcing strategies.
Maintaining relationships with suppliers outside the most exposed regions can provide alternatives when Gulf shipments become difficult.
Buyers can also review contract terms for freight adjustments, delivery windows and price formulas. Where practical, staggered purchasing can reduce the risk of committing the entire requirement at a single volatile price point.
Inventory planning also becomes more important.
Strategic stock can provide protection against short-term shipping delays, but excessive inventory can create financial exposure if fertilizer prices later decline.
The best balance depends on the product, season, supplier lead time and local consumption cycle.
Brent crude moving above $100 adds a new variable to global fertilizer cost forecasting, but oil should not be treated as a direct proxy for ammonia or urea production costs. Natural gas remains the more important direct energy and feedstock input for conventional nitrogen fertilizer, while oil primarily affects logistics and the wider energy environment.
The bigger risk comes from the possibility that the same Middle East disruption affects multiple markets at once. Gulf fertilizer exports, natural gas, ammonia, phosphates, sulfur and shipping routes can all be exposed to the same geopolitical and logistical pressures.
For procurement teams, the most effective response is scenario-based forecasting. Tracking oil alongside gas, ammonia, fertilizer benchmarks, freight and Gulf export conditions can provide a clearer view of how geopolitical developments may affect delivered costs.
