New Wave of Export Curbs on Fertilizers and Foodstuffs Raises Fresh Risks for Global Supply Chains

Recent moves by several major producers to tighten export controls on fertilizers and key food staples are reverberating through global agricultural markets. As governments respond to elevated prices and domestic shortage concerns, traders report renewed volatility in nitrogen and phosphate fertilizers and growing risk premia across wheat, rice and corn supply chains.

The backdrop is already fragile: the 2026 Strait of Hormuz crisis has pushed fertilizer benchmarks sharply higher, while China has kept nitrogen fertilizer exports curbed and introduced fresh restrictions on sulfur-linked industrial commodities. These policy measures, layered on top of elevated energy costs and geopolitically driven freight risks, are now reshaping trade flows and procurement strategies for import-dependent economies in Asia, Africa and Latin America.

Introduction

In recent days, policymakers in several exporting countries have moved to reinforce or expand export bans, licensing requirements and quotas on fertilizers and sensitive food products. The measures are framed as temporary steps to secure domestic supplies and contain inflation, but they arrive at a time when fertilizer markets are already strained by war-related disruptions in the Middle East and reduced availability from key producers.

China, the world’s largest producer of nitrogen fertilizers, has maintained tight controls that have held outbound shipments well below historical levels, while also restricting exports of sulfur-linked industrial products critical for phosphate fertilizer production. At the same time, the Hormuz crisis has lifted urea and diammonium phosphate (DAP) prices by double digits compared with pre-war levels, amplifying the price and availability impact of any new export curbs on both fertilizers and crops that depend on them for yield.

Immediate Market Impact

New and extended export licensing regimes on urea, ammonia and phosphate fertilizers are tightening prompt supply into key importing regions, particularly South and Southeast Asia. Market participants report that buyers are lengthening coverage windows and shifting tenders to alternative origins, often at higher freight and premium costs, as traditional suppliers ration export volumes in favor of domestic markets.

On the food side, traders are increasingly factoring in the risk that governments facing rising domestic food inflation could follow past patterns and impose export limits on wheat, rice or corn. Modeling studies of past crises show that even partial export restrictions can amplify global price spikes, as importing countries overbuy and re-route demand away from constrained origins. The current combination of fertilizer constraints and potential cereal export limits is therefore feeding into higher volatility across grain and oilseed futures curves and basis levels.

Supply Chain Disruptions

The convergence of export restrictions and war-related shipping risks is creating pockets of congestion and delay along major fertilizer and grain routes. Reduced flows of urea, ammonia and sulfur out of the Middle East and China are forcing importers to draw more from secondary suppliers, often through longer routes that tie up tonnage and elevate freight rates.

Import-dependent countries in South Asia, the Middle East and parts of Africa are particularly exposed, as they rely heavily on a narrow set of exporters for nitrogen and phosphate inputs. Delayed fertilizer arrivals can compress application windows, raising agronomic risk and adding another layer of uncertainty to upcoming harvests. In parallel, any new licensing constraint on cereal exports from key Black Sea, Asian or South American origins would likely trigger further front-loading of purchases and additional strain on port and inland logistics.

Commodities Potentially Affected

• Urea and other nitrogen fertilizers – Export controls from major producers and conflict-related disruptions around Hormuz have already driven prices sharply higher, tightening availability for importers.
• Phosphate fertilizers (DAP/MAP, phosphoric acid) – Restrictions on sulfur and related industrial commodities, combined with elevated energy costs, are constraining supply and raising production costs.
• Potash – While less directly targeted, potash markets remain vulnerable to broader sanctions and export policy shifts from key Eastern European and Central Asian suppliers.
• Wheat – Past episodes show wheat is often subject to export curbs during price spikes; higher fertilizer costs also threaten yield potential and production margins.
• Rice – Rice importers are sensitive to policy changes in large Asian exporters; export licensing or quotas can quickly tighten global availabilities and lift benchmark prices.
• Corn and feed grains – Elevated fertilizer prices may influence planting decisions and yields, with knock-on effects for feed markets and livestock sectors.

Regional Trade Implications

Import-dependent countries in Asia and Africa are likely to accelerate diversification of fertilizer and grain suppliers, with increased interest in secondary origins in Southeast Asia, North Africa and Latin America. Some exporters with surplus capacity, such as select nitrogen and phosphate producers outside the immediate conflict and restriction zones, stand to benefit from improved margins and greater negotiating leverage.

At the same time, traditional large exporters that tighten controls to shield domestic consumers may see market share erode as buyers seek more predictable partners. Longer term, sustained export licensing and quota regimes could encourage more regional self-sufficiency investments in fertilizer production and storage, but those projects will take years to materially change global trade patterns.

Market Outlook

In the near term, traders should expect elevated price volatility across nitrogen and phosphate benchmarks, as well as in wheat, rice and corn markets exposed to policy risk. Spot and nearby contracts are likely to command persistent risk premia over forward months, reflecting uncertainty over the duration and scope of export controls and the evolution of the Hormuz conflict.

Market participants will closely monitor any additional policy announcements from major fertilizer and cereal exporters, as well as tender activity from large importing countries. Evidence of easing restrictions or alternative supply coming online would be price negative, while any escalation in export bans or transport disruptions could trigger another leg higher in both fertilizer and food commodity prices.

CMB Market Insight

The latest wave of export restrictions on fertilizers and potential curbs on staple crop shipments underscores how quickly policy risk can reprice agricultural supply chains. For now, the direct impact is most visible in tighter fertilizer balances and higher input costs, but the downstream effects on planting decisions, yields and food inflation will unfold over coming seasons.

For commodity traders, importers and food industry buyers, the strategic response is clear: broaden origin options, secure supply through diversified term contracts where feasible, and maintain robust risk management around both fertilizer and grain exposures. In an environment where policy decisions can shift export availability overnight, agility in sourcing and hedging remains the key competitive advantage.
