World Bank Sees Grain Prices Up 9.3% in 2027 on Black Sea Risk

Grain prices will rise 9.3% in 2027, the World Bank forecasts in its October Commodity Markets Outlook — and the driver isn't demand, it's supply.

Two forces sit behind the number. First, export disruptions via the Black Sea tied to military risks. Second, shrinking production in several key growing regions. Together they squeeze a market that, on paper, still holds the second-highest global grain supply on record.

How deep does the wheat cut go?

Global wheat production in the 2026/27 marketing year will come in 3% below the previous season, the Bank projects. The country-level detail is where the margin math lives:

• United States: wheat output down 23%
• European Union: down 8%
• Canada: down 12%
• Argentina and Australia: down 23–25%

Less grain at home means less grain on boats. Global wheat exports in 2026/27 may fall 7%. Ukraine's shipments are forecast 11% lower season-over-season; Russia's, 8% lower. For buyers in import-dependent regions, that's basis-widening news before a single vessel is loaded.

What does the 9.3% forecast actually assume?

The baseline scenario is conditional, and the Bank is explicit about it. Disruptions to Black Sea shipments persist through end-2026, then ease significantly in 2027. That's the assumption underpinning the headline price rise.

The downside case is blunt. If attacks on ports and grain infrastructure continue at current intensity, and alternative export routes stay insufficient, grain prices could land significantly above forecast. In other words, 9.3% is the optimistic path, not the ceiling.

Maize: a two-decade low in the EU

The maize picture splits the map. Global production in 2026/27 falls 3%. Ukraine adds 8% and Russia 11%, partially offsetting yield losses in Argentina, Brazil, the EU and the US.

The standout figure is Europe. EU maize production could drop 20% — to its lowest level in almost two decades. That's a feed-cost problem for European livestock producers, and a demand signal for whoever holds exportable surplus.

Supply is still historically large — so why the price rise?

Here's the tension worth watching. Even after the projected decline, global grain supply in 2026/27 remains the second highest on record, roughly 3% above 2024/25 levels. Prices rising 9.3% against the second-biggest supply ever tells you the market is pricing risk, not scarcity.

Energy adds a second layer. High energy prices push up farmers' production costs — fertilizer, fuel, drying — and stimulate biofuel demand, pulling maize in particular toward industrial buyers. Both channels pressure food markets from the cost side.

What this changes for growers

For producers outside the disrupted zones, the forecast implies stronger headline prices into 2027, tempered by energy-inflated input costs. For importers and livestock feeders, especially in the EU facing a 20-year maize low, sourcing strategy gets harder before it gets easier.

Watch two things: whether Black Sea attacks persist past the Bank's end-2026 assumption, and whether Argentina's and Australia's 23–25% wheat declines hold through harvest. Either number moving reshapes the 9.3% forecast — in both directions.
