Corn and Wheat Prices Jump to Highest Levels in More Than Three Years

 Corn and Wheat Prices Jump to Highest Levels in More Than Three Years

## Two Crops, Two Crises

The numbers are stark. Wheat futures settled 3.1% higher at **784 cents per bushel** on Friday, August 28, after touching an intraday high of 790.25 cents — the highest level since February 2023. The contract gained **12.1% for the week**, its biggest weekly surge since March 2022, and is now up more than **54.5% year-to-date** .

Corn wasn't far behind. Futures settled at **536.5 cents per bushel** after hitting 541.25 cents, the highest since July 2023. Corn gained 5.5% for the week and is up **15.6% in August alone**, on pace for its best monthly performance since April 2021 .

Both crops are at three-year highs. But the forces driving these rallies couldn't be more different.

## Wheat: The Black Sea Bottleneck

Wheat's surge is about one thing: **supply disruption**. Russia and Ukraine together account for more than a quarter of global wheat exports. And right now, those exports have virtually ground to a halt .

Attacks on shipping have shut down **more than 97% of Russia and Ukraine's grain export capacity** in the Azov and Black Sea basin . Ukraine's Black Sea ports effectively ceased operations at the end of July. In Russia, the only grain terminal still operating is a small facility with a capacity of about 160,000 tons per month — a fraction of normal volumes .

The two countries had been exporting an average of **7.2 million metric tons of grain per month** from the region last season. That flow has been severed .

Global wheat prices have risen roughly **30% from a year ago**, and the pressure is mounting. While stockpiles have allowed some importers to delay purchases, traders say there are no signs of de-escalation. Russia rejected a Ukrainian proposal for both sides to halt attacks on civilian shipping, reducing hopes for a near-term recovery .

Russia can redirect some exports through Baltic, Caspian, and Far Eastern ports, but longer transport distances create logistical challenges and increase costs . Ukraine is relying on rail links with Eastern Europe and Danube River ports, but those routes can only replace about 50% of its export potential at best .

As one analyst put it: "At present, civilian shipping in the Black Sea has virtually ground to a halt" .

## Corn: The American Supply Squeeze

Corn's rally is different. It's about **the U.S. crop** — and it's not looking as plentiful as expected.

The USDA's August World Agricultural Supply and Demand Estimates (WASDE) report cut corn yield forecasts more than traders anticipated, despite projecting the second-largest harvest on record. The agency lowered its yield forecast by 2.3 bushels per acre to 180.7 .

Then came the Pro Farmer Crop Tour. The field observations were disappointing. Extreme July heat damaged the crop after excessive rain in June for many parts of the U.S. .

"From the beginning of August to now, the consensus in the market is that there is less supply than we thought at the beginning of the month," said William Osnato, Barchart director of commodity data research and analysis .

Global supplies were already tight. "We thought the world was going to be bailed out by the U.S. supply. Now the U.S. supply is becoming questionable, and the market's moving up into a rationing mode," said Jim McCormick, co-founder and chief operating officer at AgMarket.Net .

Europe's extreme summer heat also damaged its corn production, and strong export demand from the region added pressure to already-constrained supplies .

## Two Markets, One Fear

Despite their different drivers, both rallies reflect the same underlying concern: **the global food system is losing its buffer**.

The International Grains Council cut its forecast for world wheat production in 2026/27 by 4.3 million tons to 816.7 million tons, partly reflecting Europe's heat-damaged crops . The global wheat crop is now forecast at 27.5 million tons below last season .

Black Sea ports handle roughly 14% of seaborne grain volumes, and continued disruptions could have a significant impact on food prices and supply . Wheat and corn are essential staples for markets across Africa, the Middle East, Europe, and Asia .

Russia and Ukraine together account for more than a quarter of global wheat exports. When that supply is cut off, buyers must compete for grain from higher-cost suppliers like Australia and the United States — and that competition drives prices higher .

## The Bigger Picture: A Perfect Storm Brewing

The current price spike isn't happening in isolation. It's part of a broader pattern of converging risks.

The World Bank has warned that El Niño conditions, rising energy and fertilizer costs, growing biofuel demand, and potential trade restrictions could all push food prices significantly above current projections .

The closure of the Strait of Hormuz has disrupted global energy supplies and pushed fertilizer prices to their highest levels since 2022. Fertilizer — especially urea and phosphate — is critical for crop production. Higher fertilizer costs often lead farmers to use less, which can tighten food supplies and put further upward pressure on prices .

Higher crude oil prices have also increased the attractiveness of biofuels, which matters because the crops used for biofuels are the same ones that feed people. Several major economies have recently raised their biofuel blending mandates, further tightening grain supplies .

JPMorgan expects global food inflation to rise from 2.8% in the first half of 2026 to **5% in the first half of 2027**, driven by the Hormuz disruption and a potential "super El Niño" . Goldman Sachs projects global food prices could rise **15.8% cumulatively by 2028** .

## Frequently Asked Questions (FAQs)

### 1. How high did wheat prices go on August 28, 2026?

Wheat futures settled at **784 cents per bushel** after hitting an intraday high of 790.25 cents — the highest since February 2023 .

### 2. Why did wheat prices surge?

Wheat's rally is driven by **disruption to Black Sea exports**. Attacks on shipping have shut down more than 97% of Russia and Ukraine's grain export capacity. Russia and Ukraine together account for more than a quarter of global wheat exports .

### 3. How much did corn prices rise?

Corn futures settled at **536.5 cents per bushel** after hitting 541.25 cents — the highest since July 2023. Corn is up 15.6% in August and 21.8% year-to-date .

### 4. Why is corn rallying?

Corn's surge is driven by **concerns about the U.S. crop**. The USDA cut its yield forecast more than expected, and the Pro Farmer Crop Tour found that extreme July heat had damaged the crop. Global supplies were already tight, and the U.S. was expected to bail out the market .

### 5. What does this mean for food prices?

Higher grain prices will eventually translate into higher food prices. JPMorgan expects global food inflation to rise from 2.8% in the first half of 2026 to 5% in early 2027. Goldman Sachs projects a cumulative 15.8% rise in global food prices by 2028 .

### 6. Is there any relief in sight?

Black Sea exports show no signs of resuming anytime soon. Russia rejected a Ukrainian proposal to halt attacks on civilian shipping. Alternative export routes cannot fully replace Black Sea capacity, and Ukraine may face a storage deficit of up to 11 million tons by November .

### 7. What role did the U.S. crop play in corn prices?

The U.S. corn crop is central to this year's corn rally. The USDA lowered its yield forecast, and weather damage has raised concerns about supply. Europe's heat-damaged corn crop and strong export demand have added pressure .

### 8. How much of the world's wheat comes from Russia and Ukraine?

Russia and Ukraine together account for **more than a quarter of global wheat exports**. Their combined exports from the Azov and Black Sea region averaged 7.2 million metric tons per month last season .

## The Harvest of Consequences

The 54.5% year-to-date surge in wheat and the 21.8% rally in corn are not just numbers on a screen. They are signals that the global food system is under stress.

Wheat's rally is a warning about the fragility of global supply chains. A war in one region can cut off a quarter of the world's supply and send prices soaring. Corn's rally is a reminder that even the world's largest producer isn't immune to weather and crop failures.

Together, they represent the kind of supply shock that the world hasn't seen since the early 2020s. And with El Niño expected to strengthen, the Strait of Hormuz still contested, and fertilizer prices surging, this may only be the beginning.

The food system's buffer is depleting. And the bill is coming due.
