Executive Summary
A large US corn harvest is masking a tightening global supply picture as worldwide consumption is forecast to exceed production significantly during the 2026/27 season.
The latest US Department of Agriculture outlook reduced its forecast for global coarse-grain production by 5.1 million tonnes compared with its previous estimate.
US corn production was reduced by approximately 5.4 million tonnes, while expected production outside the United States was also lowered.
Reductions include India, where projected corn production has been cut by approximately 2 million tonnes.
Global corn consumption is now forecast to exceed production by almost 30 million tonnes during 2026/27.
If realised, that would represent the largest annual production deficit in more than three decades.
The risk is easily overlooked because the United States is still harvesting a very large crop. Global availability, however, depends upon consumption and stocks as well as headline harvest size.
UK Impact
Corn is embedded throughout food and agricultural supply chains.
UK exposure includes:
- Animal feed.
- Poultry.
- Pork.
- Dairy.
- Food manufacturing.
- Starches.
- Sweeteners.
- Biofuels.
Higher feed costs can move through the supply chain into meat and dairy prices.
Businesses should therefore monitor not merely UK or European crop conditions but the international balance between supply and consumption.
Global Impact
The USDA’s latest outlook points to tightening global coarse-grain stocks.
This matters because corn has several competing uses:
- Human food.
- Animal feed.
- Ethanol.
- Industrial processing.
Demand therefore does not originate from one sector.
Weather conditions add another layer of uncertainty as the developing El Niño pattern affects agricultural regions differently around the world.
Businesses should avoid assuming that El Niño will uniformly reduce production.
Its effect varies substantially by crop and geography.
However, a tighter starting inventory position means future weather disruption could have a greater effect on prices than it otherwise would.
Our View
Food and agricultural businesses should distinguish between a large harvest and a comfortable global balance sheet.
Companies should ask:
- How much corn exposure exists within products?
- Is exposure direct or through animal feed?
- Where is corn sourced?
- Are contracts fixed-price?
- When do contracts reset?
- How much inventory is held?
- Could alternative feed grains be used?
- Are substitutions nutritionally and commercially viable?
- How exposed are suppliers to weather?
- Are livestock producers experiencing margin pressure?
- Could higher feed costs affect supplier solvency?
- Are ethanol mandates increasing competition for grain?
- Could export restrictions emerge if prices rise?
- Are customers able to absorb price increases?
- Could El Niño materially affect key producing regions?
- Are procurement forecasts based upon headline production rather than global stocks?
The central lesson is straightforward.
Record or near-record production does not necessarily mean abundant supply when consumption is rising faster.
For businesses, the relevant measure is not how much the world produces — it is how much remains after the world has consumed it.
