Fertilizer Supply Normalisation Accelerates as US Iran Deal Shifts Bearish Outlook for $780 Urea Peak

The Diplomatic Breakthrough Reshaping Commodity Markets

The diplomatic landscape between the United States and Iran shifted significantly over the 48 hours ending May 7, 2026. US President Donald Trump indicated that productive discussions with Tehran had raised the possibility of a comprehensive agreement, prompting a pause in the military escort operation known as Project Freedom.

A one-page, 14-point memorandum of understanding is under active negotiation, brokered through Pakistani intermediaries. The framework would declare an end to hostilities and initiate a 30-day period of detailed talks covering the reopening of the Strait of Hormuz, limitations on Iran's nuclear programme, and the phased lifting of US sanctions.

The immediate market response was severe. Brent crude plunged as much as 12% to $96.73 per barrel on May 6, before stabilising above $101 on May 7. WTI crude fell as much as 13.3% to $88.66 before recovering above $95. Corn and soybean futures followed energy markets lower, as the war premium that had supported prices since late February began to unwind.

Strait of Hormuz Reopening and the Fertilizer Supply Chain

The Strait of Hormuz has been effectively closed to most commercial shipping since the US and Israel launched strikes on Iran on February 28, 2026. The disruption represents the largest interruption to global energy supply since the 1970s oil crisis.

For global fertilizer markets, the closure has been particularly damaging. Approximately one-third of all seaborne fertilizer trade transits the strait, according to the United Nations. The Gulf region produces nearly half of the world's urea and 30% of global ammonia output. An estimated 30% of globally traded urea originates from Iran and Hormuz-constrained producers including Saudi Arabia, Qatar, and Bahrain.

Since late February, transit volumes through the strait have fallen by more than 95% from pre-conflict levels. QatarEnergy halted downstream urea production after suspending liquefied natural gas output. China imposed export controls on urea and fertilizers in March to protect domestic supplies. These compounding supply losses removed the world's largest swing suppliers from global markets simultaneously.

If the MOU is finalised and the strait is declared open to all shipping, stalled consignments of urea and sulphur could begin reaching destination markets by late June 2026. However, the logistical realities of recovery are significant: clearing naval mines, restoring damaged port infrastructure, and restarting idled ammonia plants across the Gulf region will require weeks to months.

Urea Price Outlook Under the Agreement Scenario

With the prospect of a deal now on the table, the urea price outlook has shifted. Analysts project that urea prices will peak in June 2026 at approximately $782 per ton before entering a steady decline, rather than remaining elevated through the northern hemisphere winter as previously forecast.

The US Iran deal, if completed, would represent the single largest bearish catalyst for nitrogen fertilizer markets since the conflict began. However, even a signed agreement does not translate to immediate supply restoration. The World Bank's latest Commodity Markets Outlook projected a 31% increase in global fertilizer prices for 2026, warning that average urea prices could exceed the 2022 average of $700 per metric ton if disruptions persist.

The fertilizer price index rose by more than 12% in the first quarter of 2026 alone, reaching levels not seen since the 2022 energy crisis. Benchmark granular urea prices moved from the $450 to $500 per ton range in February to $650 to $700 in key markets by late March.

Current Fertilizer Price Snapshot

As of the morning of May 7, 2026, nitrogen-based fertilizer prices remain sharply elevated from pre-conflict levels, while phosphate and potash markets have experienced more modest movements.

Anhydrous ammonia has surged approximately 35% since February, rising from $828 per ton to $1,123. Urea at the NOLA benchmark is trading in a volatile $580 to $780 range, reflecting a 25% to 45% increase. DAP and potash prices have remained broadly stable, underscoring the concentration of supply disruption in nitrogen products.

This pricing pattern aligns with analysis from CRU Group, which noted that approximately 30% of exportable urea supply is currently unavailable to the global fertilizer market. The disruption has extended beyond nitrogen into sulphur markets, as the Gulf produces 44% of global supply. Sulphur scarcity is cascading into phosphate fertilizer production worldwide, compounding the nitrogen shortfall.

Agricultural Market Spillover

The knock-on effects for agricultural commodity markets have been substantial. Corn and soybean prices are heavily linked to energy costs through biofuels blending economics and to fertilizer costs through input pricing.

Corn futures followed energy markets lower on May 6 and into overnight trading on May 7 as the war premium began to evaporate. July corn fell to $4.6750 per bushel, its lowest intraday price since late April. July soybeans declined to $12.0475, retreating from a seven-week high.

The broader concern for 2026 crop production centres on planting decisions already made under elevated input costs. Surveys indicate that 48% to 70% of US farmers reported difficulty affording full fertilizer applications for the 2026 season. Some acreage is believed to have shifted from nitrogen-intensive corn to soybeans, though the extent of this shift remains uncertain ahead of USDA's June acreage update.

The World Food Programme has warned that prolonged disruptions could push up to 45 million additional people into acute food insecurity, with import-dependent economies in East Africa and South Asia facing the greatest exposure.

The Wildcard: Verification and Sequencing Risks

While the diplomatic path appears more promising than at any point since the conflict began, significant obstacles remain. The verification of nuclear curbs and the sequencing of sanctions relief are major sticking points in the negotiation.

The duration of a moratorium on uranium enrichment is under active discussion, with reports indicating a range of 12 to 15 years under consideration. Iran would need to commit to enhanced UN inspections, including snap checks, and to removing its stockpile of highly enriched uranium from the country. The White House has acknowledged that Iranian leadership is divided, complicating efforts to forge consensus across political factions.

If these final hurdles derail the memorandum, the war premium could return to energy and fertilizer markets rapidly. As ING's head of commodities strategy Warren Patterson noted, roughly 13 million barrels per day of disrupted oil supply is being offset by inventory drawdowns, leaving the market increasingly vulnerable with each passing day. Tighter stocks will leave commodity markets trading in an increasingly volatile manner if diplomatic progress stalls.

For fertilizer markets specifically, the stakes extend beyond pricing. A prolonged disruption would reduce crop yields in the 2026 to 2027 season, transmitting the supply shock from energy and fertilizer markets directly into global food systems. The global fertilizer market has no equivalent of strategic petroleum reserves, making supply disruptions harder to absorb and slower to resolve.
