Perfect Storm for Grocery Prices: How the US-Iran Conflict Impacts Your Weekly Shop (2026)

The Rising Cost of Groceries: A Perfect Storm Unveiled

The warning signs are clear: a perfect storm is brewing, and it's about to hit our grocery bills. Australians, brace yourselves for a significant impact on your weekly shop.

The Global Impact

The ongoing conflict between the US and Iran has sent shockwaves through global markets, with fuel prices remaining stubbornly high. This crisis has infiltrated every link of the supply chain, as highlighted by Colm Maguire, CEO of the Australian Food and Grocery Council (AFGC). From farm to factory, the cost of doing business has shifted fundamentally. Fertilizers, fuel for transportation, and energy for production have all become more expensive, creating a complex scenario for the industry.

Navigating the Oil Crisis

AFGC members are meticulously assessing how the oil crisis will affect grocery prices. It's a challenging task, as the impact is felt across various inputs, including fertilizer, oil, transportation, energy production, and even the cost of plastic packaging. Mr. Maguire emphasizes that a simple percentage increase across the board is not feasible, and individual producers and suppliers must navigate this complex landscape to determine their bottom line.

The Strait of Hormuz, a critical chokepoint for global oil supply, has been blocked, leading to a rapid rise in fuel costs. Oil prices, which were around $56 per barrel in January, have fluctuated between $100 and $110 per barrel since the Middle East conflict began. This has a direct impact on transportation costs, with Australians paying an extra 10 cents per liter at the pump for every $10 increase in oil prices.

Beyond Transportation Costs

The impact of rising oil prices extends far beyond transportation. Mr. Maguire points out that the industry is facing price pressures on multiple fronts. From the plastic wrapping on bread to the bottles for milk and even tissue boxes and nappies, the reach of oil and petrochemicals is broad. While the initial focus may be on fuel costs, the flow-on effects through packaging, a critical component of the grocery industry, will inevitably lead to increased costs.

Absorbing the Increases

Australian manufacturers, suppliers, and retailers have been absorbing these increases to protect consumers during a cost-of-living crisis. However, as the crisis continues, costs will have to be passed on. A separate report by Rabobank highlights the challenges faced by dairy producers, with rising input costs stretching margins.

Dairy Producers and Farmers

Dairy producers are entering the 2026/27 season with limited room for error. While seasonal conditions have improved, they cannot offset the compounding cost pressures. Processors face higher packaging costs due to the oil supply crisis, and energy, processing, and distribution costs have all increased. Norco, a farmer-owned dairy cooperative, has already announced a price hike of 5 cents per liter to tackle rising freight costs, which will add approximately 30 cents per week to the average household grocery bill.

Farmers are warning of an impending milk price surge due to these higher input costs. Woolworths has announced it will pay farmers directly linked to its Farmers Own Brand 10 cents more per liter, benefiting around 20 farmers. Lactalis, the nation's largest dairy company, will also pay an additional 5 cents per liter to more than 800 farmers starting May 1.

The Australian Dairy Farmers have called for a 20% rise across the board, arguing that this would allow some money to flow through to the farmers after suppliers, retailers, and the government take their cut.

Consumer Resilience

Michael Harvey, RaboResearch's senior dairy analyst, warns that a renewed cycle of food price inflation, including for dairy, would further test consumer resilience. Households are already adjusting their behavior, opting for private-label products and prioritizing value over brand. The price increases are being felt beyond the farm gate, constraining the ability of processors to absorb additional cost shocks and potentially leading to further interest rate hikes.

Conclusion

The perfect storm hitting grocery prices is a complex and multifaceted issue. It highlights the interconnectedness of global markets and the impact of geopolitical tensions on our daily lives. As consumers, we must navigate these rising costs and adapt our spending habits accordingly. The coming months will be crucial in understanding the full extent of this crisis and its long-term effects on our grocery bills.
