A potentially record-strength El Niño is not creating one agricultural trade. Sugar carries the clearest near-term price risk, corn exposure builds with South America’s 2026/27 crop cycle, while larger global supplies give wheat more room to absorb a regional weather shock.
NOAA now sees a 75% probability that October–December RONI reaches at least +2.5°C, a level that would exceed every El Niño event in its post-1950 RONI record.
| Commodity | Risk now | Main pressure | Critical window |
|---|---|---|---|
| Sugar | Highest near term | Brazil output mix, weaker Thailand crop | Q4 2026–Q1 2027 |
| Corn | Building | Tighter balance, South America weather | Q4 2026–Q2 2027 |
| Wheat | Better buffered | Australian harvest weather | Sep–Dec 2026 |
Global food markets are entering the event from firmer levels. The FAO Food Price Index rose 1.9% month on month to 133.3 in August. Its Sugar Price Index jumped 11.9%, while world wheat prices rose 2.6% and international maize prices increased 2.5%.
Those moves reflect several supply, demand, trade and weather forces, but they show that the three markets are not starting from the same price backdrop.
Brazil could harvest substantially more sugarcane in 2026/27 and still produce less sugar. Cane production is projected to rise 4.7% to 705.2 million tonnes, while sugar output falls 2.9% to 42.89 million tonnes and cane-based ethanol production rises 9.7% to 29.98 billion litres.
Global sugar availability depends on how much cane mills convert into crystallised sugar. A larger Brazilian cane crop does not automatically translate into more exportable sugar.
Thailand adds pressure, with 2026/27 sugar production forecast at 9.5 million tonnes, around 16% lower, and exports projected to fall about 14% to 6.0 million tonnes. India provides the strongest offset, with output forecast to rebound 12% to 33.6 million tonnes from a revised 30 million tonnes in 2025/26.
That leaves India’s recovery carrying significant weight in the current supply outlook. A weaker-than-expected Indian crop would leave sugar considerably more exposed as El Niño approaches its expected peak.
Corn enters the coming weather window with less balance-sheet protection than it had in August.
USDA cut projected 2026/27 world corn production by 7.93 million tonnes to 1,290.95 million tonnes, while global ending stocks fell by 2.56 million tonnes to 272.10 million tonnes. US ending stocks declined from 1.653 billion to 1.567 billion bushels, and the season-average farm-price forecast rose from $4.50 to $4.80 per bushel.
The next major variable is planting progress, not the El Niño label itself. Argentina’s main corn planting window runs from roughly September through November, while Brazil’s larger second corn crop depends on how quickly soybeans are planted and harvested first.
Earlier soybean planting gives Brazilian corn more time to establish before seasonal rainfall fades. Delays compress that window and increase exposure to poorer conditions later in the cycle, while adequate early moisture can still support establishment.
The next significant corn repricing is therefore more likely to come from planting delays or deteriorating reproductive conditions than from El Niño strength alone.
Wheat faces genuine Australian weather risk, but September’s global supply revisions moved in the opposite direction to corn.
Projected 2026/27 world wheat production rose from 819.30 million to 822.43 million tonnes, while ending stocks increased from 273.25 million to 276.29 million tonnes. Australia’s production forecast climbed from 28 million to 31 million tonnes, up about 10.7% in one month.
Australia still faces harvest exposure. The October–December outlook favours below-average rainfall across much of the southeast and above-average temperatures across most of the country, while wetter conditions are expected across large parts of western and central Australia.
The risk is therefore regional rather than a nationwide drought signal. Australian yield or quality deterioration could restore a wheat weather premium, but higher global production and stocks do not eliminate export-market risk.
The strongest El Niño readings and the strongest inflation effect would not necessarily occur together.
Commodity markets can price weather risk within days. Retail food inflation moves through a slower chain involving crop yields, harvests, trade, processing, transport and final pricing. A short-lived futures premium alone is not enough to produce sustained consumer inflation.
US food-at-home prices are currently forecast to rise 2.1% in 2027, although the 95% forecast interval spans -5.7% to +10.5%. Much of next year’s food-price outlook therefore remains unresolved before the 2026/27 crop outcomes are known.
The timing points to late-2026 commodity repricing first, followed by any broader retail-food effect in 2027 if crop losses prove large and persistent enough to pass through processing and distribution.
That inflation risk would ease if India’s sugar rebound exceeds expectations, South American corn planting stays on schedule, or Australian wheat harvest results preserve both yield and quality.
NOAA also cautions that a stronger RONI raises the probability of characteristic El Niño impacts but does not guarantee extreme weather in every producing region. Record-strength ocean conditions would not automatically produce record agricultural damage.
No. Price reactions depend on where weather anomalies occur, the crop’s development stage, inventories, export availability and the market’s starting supply position. A severe climate event can produce a limited global price response when stocks are ample, while a smaller disruption can move a tighter market sharply.
Australian wheat harvest results should provide one of the earliest signals during late 2026. South American corn risks become clearer as Argentine planting develops and Brazil moves from soybean harvesting into second-crop corn planting. Asian sugar production estimates will provide another key test through late 2026 and early 2027.
Yes. El Niño strength describes conditions in the tropical Pacific, not guaranteed crop losses. Regional rainfall, temperature, crop timing and existing inventories determine the eventual supply effect. Wheat currently demonstrates that distinction because global production and stocks have risen even as the El Niño outlook has intensified.
Sugar, corn and wheat enter a potentially historic El Niño with very different supply buffers, making the next crop results more important than the climate headline alone. Australian wheat harvests provide the first major test in Q4 2026, followed by South American corn planting and reproductive conditions through early 2027 and updated Asian sugar output across the 2026/27 crushing season.
Those results will determine whether today’s weather premium develops into a broader 2027 food-price shock or fades as supply proves more resilient.
