What Has Happened in the Middle East?
The conflict in the Middle East escalated over the weekend through USA involvement, as the United States and Israel launched large-scale strikes on Iran. These strikes targeted military infrastructure, missile capabilities and sites linked to the country’s nuclear program, reportedly striking nearly 2000 targets across more than 130 Iranian cities – including command centres of the Islamic Revolutionary Guard Corps, naval assets and missile launch facilities. The strikes have triggered Iranian retaliation across the region and heightened fears of broader regional escalation, with President Donald Trump indicating operations could continue for several weeks. The situation has rapidly become a key geopolitical risk for global markets, particularly due to Iran’s proximity to the Strait of Hormuz, a critical trade route for energy and fertiliser shipments.
The Strait of Hormuz
As one of the most critical trade corridors in the global economy, The Strait of Hormuz is located between Iran and Oman- connecting the Persian Gulf to global markets. This narrow shipping lane handles a significant share of the world’s energy and fertiliser trade, with approximately 20 million barrels of crude oil passing through per day (~20% of global consumption), and one fifth of global liquefied natural gas (LNG) trade.
Agricultural inputs are also directly impacted, with 25-35% of globally traded ammonia and urea fertiliser passing through the strait, with the Middle East also accounting for 40-50% of globally traded urea – meaning the current disruptions can significantly and rapidly tighten fertiliser availability.
Since the conflict escalated, shipping activity through the Strait of Hormuz has already been disrupted. Maritime monitoring groups have reported declines in tanker traffic, electronic interference affecting vessel tracking systems, and several attacks on ships near the mouth of the Persian Gulf, including a drone strike on an oil tanker in the Gulf of Oman. Rising war-risk insurance premiums and safety concerns are also discouraging vessels from transiting the region, effectively restricting shipping even without a formal blockade. For agricultural markets, the implications are significant, as disruptions to energy shipments can lift global oil and diesel prices, while interruptions to natural gas and fertiliser exports quickly increase nitrogen fertiliser costs in a market that operates with limited global stockpiles and just-in-time supply chains.
Energy Markets React: Oil Volatility Returns
Energy markets reacted quickly to the escalation in the Middle East, with Brent crude rising from around US$72 per barrel in late February to above US$80–84 per barrel within days, a gain of roughly 10–15% as traders priced in the risk of supply disruptions. Diesel and natural gas markets have also moved higher, with U.S. diesel prices reportedly rising by around 10% amid tightening supply expectations. For growers, the main implication is indirect: higher oil prices typically translate into higher fuel, freight and fertiliser production costs, as nitrogen fertiliser relies heavily on natural gas and global transport costs rise alongside energy prices.
Fertiliser Supply at Risk
The Middle East is a key global supplier of fertilisers and fertiliser feedstocks, particularly urea, ammonia and sulphur, with major exporters including Iran, Qatar and Saudi Arabia. Any disruption to production, export logistics or shipping routes in the region can quickly tighten global supply. Since the conflict escalated, this market has already begun reacting to rising natural gas and freight costs, as nitrogen fertiliser production is highly energy-intensive and heavily dependent on gas prices. For Australian growers, the risk is that continued instability could push nitrogen fertiliser prices higher in coming months, particularly if shipping through key trade routes slows or energy costs remain elevated.
Freight and Shipping Disruptions
The widening conflict is increasingly affecting global shipping lanes beyond the Middle East itself. In the past 24 hours the situation escalated further after a U.S. submarine torpedoed the Iranian frigate Iris Dena in the Indian Ocean near Sri Lanka, marking the first sinking of an enemy vessel by U.S. torpedo since World War II. The incident occurred roughly 44 nautical miles off Sri Lanka’s southern coast, along a key maritime corridor linking the Middle East with Asia. A second Iranian naval vessel, the Irins Bushehr, subsequently requested emergency docking in Sri Lanka after engine failure, highlighting the growing military presence and disruption across shipping routes that connect the Persian Gulf, Indian Ocean and Asian trade lanes.
For Australia’s agricultural sector, the significance lies in how these events affect global maritime freight networks. The Indian Ocean shipping corridor is one of the primary routes used for fertiliser, chemicals, fuel and other agricultural inputs moving from the Middle East and Asia into Australia, while Australian grain exports frequently transit the same broader trade network when heading toward markets in Asia, the Middle East and North Africa. Escalating naval activity, higher war-risk insurance premiums and shipping detours around the Cape of Good Hope are already raising freight costs and creating delays across global trade. If the conflict continues to intensify, Australian growers could face higher landed costs for imported inputs and increased freight volatility for exported grain, even if Australian ports themselves remain unaffected.
Commodity Markets: Early Moves in Grain and Oilseeds
Grain and oilseed markets have responded to the Middle East escalation with increased risk premiums and directional movement over the past week. Chicago futures show strength: wheat has risen roughly 1–1.5%, corn is marginally higher, and soybeans have gained modestly alongside a rally in soybean oil- itself supported by higher crude prices as markets price ongoing supply risk and elevated biofuel margins. Commodities analysts note that soybean oil and wheat have tended to co‑move with crude during sharp oil rallies, providing spill‑over support to agricultural markets.
The Australian dollar has weakened against the U.S. dollar in recent sessions amid risk‑off sentiment, trading near 70 US cents, which further bolsters returns for Australian exporters when grain prices are expressed in AUD. This has prompted some growers to consider forward selling or marketing, especially as farm input costs – particularly fertiliser and diesel – are expected to remain elevated, squeezing margins and increasing the need for cash flow ahead of the planting season. Elevated futures prices, combined with a softer AUD, help lift domestic bids and improve revenue prospects for growers needing to cover higher projected input costs.
Overall, while underlying supply and demand fundamentals still weigh on markets, current price action reflects short‑term volatility driven by energy risk, freight disruption concerns and input cost pressures, with growers increasingly watching both futures and currency moves to time sales in the context of rising costs.
Scenarios/Key Indicators to Watch
- Strait of Hormuz activity – any further disruption could push oil, diesel, and fertiliser prices higher.
- Energy markets – crude oil and LNG prices remain highly volatile; sustained spikes directly affect production costs.
- Fertiliser markets – nitrogen and phosphate availability, shipping disruptions, and production constraints will influence input pricing.
- Agricultural futures & AUD/USD exchange rate – higher commodity prices paired with a weaker AUD can improve export returns.
- Geopolitical developments – military escalation, sanctions, or new trade restrictions could extend volatility across markets.
What It Means for Australian Growers
Australian farmers are facing a rapidly changing cost environment. Fertiliser, diesel, and other inputs are likely to rise due to supply disruptions in the Middle East, just-in-time shipping challenges, and natural gas price spikes affecting nitrogen production. Meanwhile, commodity prices for wheat and oilseeds have rallied, supported by higher oil prices, risk premiums, and a softer AUD, offering growers potential revenue gains. However, tighter cash flow may force growers to sell some grain early to fund the next season’s inputs, highlighting the need for careful financial planning.
Short-term, growers may benefit from elevated commodity prices, but rising input costs and ongoing supply chain risks are tightening margins. Working with a grain broker can provide insight into market trends and timing, helping growers make more informed decisions around selling and cash flow. Staying aware of price movements and market indicators with expert guidance can help ensure costs for the next season are covered while taking advantage of favourable prices.
