August handed sugar futures a 21.5% gain — the sweetener’s strongest month since October 2010, when it climbed 24%, and enough to lift the commodity above the stock market’s 2026 performance.
For the year, sugar sits roughly 20% higher. The S&P 500 has put together close to 13% across the same period. Earnings and interest-rate bets explain one of those figures. The other traces back to heat waves, a monsoon that never arrived, and a nation that flipped from exporter to buyer.
Europe’s beet crop broke first
What set the move off was weather across the European Union. According to William Osnato, Barchart’s director of commodity data research and analysis, harm done to Europe’s sugar-beet crop during a summer heat wave ranked among the single biggest immediate drivers.
Beets occupy the same fields and the same growing calendar as corn and wheat — which is precisely why a heat wave that damages one damages all three.
“That’s been factored in over the last month. So a bunch of organizations lowered their production estimates,” Osnato said.
And lower them they did. The most recent sugar balance sheet from the European Commission has EU output falling 19% to 13.4 million metric tons in the 2026/27 marketing year, down from 16.6 million tons a year earlier in 2025/26.
Everyone’s deficit number is different, and that’s the point
In a note published Tuesday, Citi pencilled in a global shortfall of 1.3 million metric tons. Green Pool Commodity Specialists pegged the gap at 3.2 million metric tons. The spread between those estimates is wide — and less important than the fact that both point the same way.
“What is usually consistent is that they’re all going in the same direction,” Osnato said. “They’re all increasing the deficit.”
Among agricultural commodities trading on the Intercontinental Exchange, Citi labelled sugar its “highest-conviction bullish” market. The bank lifted its three-month target to 19 cents per pound, pointing to shrinking inventories, India’s surprise import program, and worsening weather across India, Thailand and the EU.
India stopped being a seller
India — the second-biggest producer on earth after Brazil — has just cleared 1 million metric tons of duty-free raw-sugar imports. Officials framed the move as a way to shore up domestic supply in the face of weaker production, seasonal demand and climbing prices.
The detail worth holding onto: per Osnato, the authorization came on the heels of two disappointing crops and marked India’s first since the 2017-2018 season. Should India take up even roughly half the approved volume, he said, the decision supports the case that supplies are tighter than earlier estimates suggested.
With India curbing exports at the same time it steps in on the buy side, the world loses twice over on available supply.
Rain across India’s core sugar-growing regions has come in below normal levels. A feeble monsoon empties reservoirs, and empty reservoirs make farmers reluctant to plant something as thirsty as sugarcane in the season that follows.
The forward-looking problem is a Pacific temperature reading
The climate pattern that brings warmer seas and violent weather — El Niño — is in Osnato’s view probably “the biggest forward-looking concern.”
One figure explains why that carries weight. A multi-model median forecast from The Climate Brink has the temperature anomaly in the Pacific’s Niño 3.4 region topping out around 3.9 degrees Celsius — roughly 39 degrees Fahrenheit — in November. A very strong El Niño is defined at 2 degrees Celsius, or 35.6 degrees Fahrenheit.
Between them, Brazil, India and Thailand supply something like 70% of the world’s sugar exports. Goldman Sachs noted that drought over the growing season can suppress cane yields, while too much rain at harvest can stall work in the fields and dilute the sugar content of the cane. Abnormally warm Pacific waters are also forecast to deliver unpredictable rainfall and water shortages throughout Thailand.
Brazilian mills can just decide to make something else
Brazil on its own supplies close to half of global sugar exports, and its mills are free to swing their output between sugar and ethanol based on which one pays more. At the moment, energy prices are pushing that decision in one direction.
“When the price of oil increases, countries that produce ethanol from sugar have a higher incentive to produce more ethanol and export less sugar to the global market,” said Rob Johansson, director of economics and policy analysis at the American Sugar Alliance.
“With oil prices over $90 a barrel, countries like Brazil, which heavily subsidizes its ethanol industry, are producing more biofuel, lowering the amount of sugar available on the market and putting upward pressure on prices,” Johansson said.
Goldman Sachs points to a knock-on version of the same dynamic. Because corn feeds ethanol production alongside sugarcane, a corn crop weakened by El Niño-driven drought could draw still more cane into ethanol and leave less sugar destined for export.
Where this trade falls apart
Harvesting in Brazil has been held up by rain, Osnato said, and part of that output may yet be salvaged once fields dry. Recovering sugar content in Brazil, or a quicker harvest, stands out as one of the most obvious threats to the price on the downside.
The Food Price Index compiled by the U.N.’s Food and Agriculture Organization also climbed in August on broad-based gains, with sugar leading the way.
“The surge reflected expectations of lower sugar beet yields in the European Union due to adverse weather, concerns over the impact of El Niño on production prospects in key producing countries in Asia, lower sugar production in Brazil, and India’s announcement of duty-free raw sugar imports,” the organization said in its recent report.
Four causes, all pushing the same way. And each of them leads back to one country.
“Brazil remains the market’s key balancing supplier, but weather-related execution risks during the remainder of the harvest leave little margin for error,” Citi analyst Arkady Gevorkyan wrote in a note.
Between now and November, the single variable worth tracking is how quickly Brazilian fields dry out. The rest of this rally is already in the price.
