Brazil's Wet Weather Curbs Sugar Output Despite Price Surge

Unusually wet weather in Brazil is overriding strong price signals for sugarcane processors, forcing them to favor ethanol production over sugar and potentially tightening global supplies. Analysts and traders report that despite a significant price advantage for sugar, mills are constrained by high moisture content in the cane, a direct result of El Niño weather patterns.

Weather Overrides Price Signals

Raw sugar futures jumped more than 21% in August, creating a clear financial incentive for Brazilian mills to maximize sweetener production. The profitability gap is currently around 20% in favor of sugar over ethanol, according to Fabio Meneghin, a partner at Veeries consultancy, who was cited in a Reuters report.

However, persistent rains have saturated the sugarcane, boosting vegetation growth but reducing the concentration of sucrose. While this high moisture content is detrimental for efficient sugar crystallization, it does not negatively impact the fermentation process for ethanol. "In the end, we are not looking anymore at market prices to guess the production mix... The focus is the climate," said Marcelo Bonifacio Filho, a sugar analyst for broker StoneX.

Production Forecasts Trimmed

The global sugar market closely monitors the production mix in Brazil—the percentage of sugarcane allocated to sugar versus ethanol—as it determines the total supply from the world's largest producer. A shift of just one percentage point toward sugar can introduce an additional 750,000 metric tons to the market.

Reflecting the weather-related constraints, StoneX has already lowered its production forecast for Brazil's Center-South region to below the 40 million metric tons expected at the start of the harvest. The brokerage now sees a possibility that total output may not surpass 38 million tons, with senior analyst Michael McDougall noting that further downgrades are possible if heavy rains continue into October.

Implications for Global Prices

The inability of Brazilian mills to respond to higher prices could have significant implications for the market. According to trader GSX Commodities, the current sugar price rally could be capped if mills manage to increase their sugar mix and bring additional supply online.

Conversely, if wet conditions persist, preventing both a shift in the production mix and the complete harvesting of available cane, sugar prices could move higher. The harvest was already experiencing delays after some parts of Brazil's sugar belt recorded the wettest winter in over a century, according to the University of Sao Paulo.
