Brazilian Mills Shift Sugarcane to Ethanol as Sugar Prices Sink Below Production Costs

Brazilian mills are entering the 2026/27 season with a clear bias toward ethanol production, a strategic pivot driven by deteriorating macro conditions for sugar and a structural increase in energy costs. This shift is a direct response to the unfolding commodity cycle, where real interest rates, currency dynamics, and inflation are redefining the profitability calculus for cane.

The immediate pressure on sugar is stark. Global prices are under clear downward pressure, with New York futures for the March 2027 contract trading around 15 cents per pound. More critically, Brazilian mills are reporting that their sugar production costs are around $16.30 per pound. This creates a direct cost-price squeeze, making sugar production uneconomical at current levels. The market outlook reinforces this, with forecasts pointing to consecutive global surpluses over the next two seasons, which reduces the likelihood of a near-term price recovery. In this environment, the flexibility to redirect cane from sugar to ethanol becomes a vital earnings protection tool.

At the same time, the cost of the other key input-electricity-is rising structurally. The Brazilian National Electricity Agency has set the 2026 optimized energy price standard at R$18.27 per MWh, with a structural maximum limit of R$785.27 per MWh for thermal generation. While the base price increase is tied to inflation, broader market projections indicate that electricity bills are expected to rise above inflation again in 2026, with estimates ranging from around 5% to 8%. This increase is driven by a multi-billion dollar rise in sector subsidies, which will be passed through to consumers. For mills, higher energy costs directly improve the relative economics of producing ethanol, which can be seen as a form of on-site energy generation.

The bottom line is a convergence of forces. When sugar prices fall below the cost of production, and the cost of the energy used in processing rises, the margin for ethanol production becomes more attractive by comparison. This macro setup is compelling mills to adjust their sugar-ethanol mix, with analysts already revising projections to show a reduction in sugar production in central-south by 700,000 tonnes. The pivot is less about a sudden boom in biofuel demand and more about a cyclical response to a deteriorating sugar price environment and a rising energy cost floor.

The Production Pivot: Quantifying the Shift

The operational shift is now well underway, moving from a strategic consideration to a quantifiable reality. Market sources estimate that sugar production in Brazil's central-south region will fall between 800,000 and 2 million tonnes below the latest estimates, approaching 40 million tonnes. This shortfall directly translates to a significant ethanol windfall, with output potentially 500 million liters to 1.4 billion liters higher than the latest projections for the 2026/27 season.

The pivot is accelerating, with clear milestones marking the change in direction. The week ending August 19th served as the peak for sugar bets, with 63.3% of sugarcane juice allocated to sugar. By the week ending September 30th, that allocation had plummeted to 57.9%. This decisive shift began in earnest in October, following the consolidation of ethanol's price advantage and the implementation of the new 30% ethanol blend in gasoline.

The move is incentivized by a combination of firmer ethanol prices and a resilient domestic market. As Copersucar's CEO noted, ethanol prices have risen amid a tight supply balance, with demand remaining firm. This creates a buffer for producers, as the country's large and liquid domestic market can absorb a significant share of production. The price action supports this: hydrous ethanol prices in São Paulo began rising in the second half of July and have since increased by 8%, with prices last week being 16% higher than the same period in 2024.

The change is being driven by major players. Companies like Cofco and São Martinho began shifting their mix in August and September, respectively, with Cofco now expecting to produce 65 million liters more ethanol. This momentum is spreading, with mills in tax-incentive states and larger groups like Copersucar, Raízen, and bp bioenergy following suit in early October. The bottom line is a sector recalibrating its output mix in real time, with the production pivot now a central feature of the 2026/27 season.

Market Implications and Cyclical Trade-Offs

The production pivot has tangible consequences for global markets, creating a complex trade-off between near-term supply tightening and a longer-term bearish structural trend. A significant reduction in Brazilian sugar output-estimated at 800,000 to 2 million tonnes-will tighten the physical supply of the world's top exporter. This shift is already showing in price action, with sugar futures settling higher in recent sessions as a stronger Brazilian real discouraged export sales, potentially reducing flows. For now, this supply shock offers a buffer against the broader price decline.

Yet this near-term support is likely to be capped by the global cycle. The market outlook remains one of consecutive surpluses, with forecasts pointing to consecutive global surpluses over the next two seasons. This is driven by a recovery in output elsewhere, particularly in India, where production is surging. In this context, any rally in sugar prices is likely to be shallow and temporary. The pivot in Brazil, while a major event for the sector, does not alter the fundamental supply-demand imbalance that has been building.

The shift also alters trade dynamics. With Brazil's sugar exports expected to fall -11% year-over-year in the 2026/27 season, the country's role as a supplier is diminishing. This creates a potential opening for other exporters, like India, to step in and fill the gap. However, India's own export plans are constrained by domestic policy, limiting its ability to fully offset the Brazilian shortfall. The result is a more fragmented and volatile global trade picture.

For ethanol, the outlook is more straightforwardly positive. The pivot directly translates to a potential 500 million liters to 1.4 billion liters higher in Brazilian ethanol production. This boost aligns with a firm domestic market and rising prices, providing a clear earnings outlet for mills. However, the cycle here is also defined by its own constraints. The surge in output is a response to a deteriorating sugar market, not a fundamental boom in energy demand. As such, the ethanol market's strength is intrinsically linked to the sugar price environment and the macro pressures that drove the pivot in the first place. The bottom line is a sector navigating a cyclical trade-off: protecting earnings today by shifting production, but doing so within a global market that still expects ample supply.

Catalysts and Risks: Confirming the Macro Cycle

The emerging cycle for Brazilian biofuels is now set in motion, but its trajectory hinges on a few key variables. Mills are likely to prioritize ethanol production at the start of the 2026–27 crushing season as stronger prices incentivize diverting cane away from sugar, according to top producer Copersucar SA. This initial push is expected to be concentrated in the early months, offering a near-term supply shock to global sugar markets. However, the pace of the shift will be determined by the timing of the harvest start and weather conditions, with any heavy rainfall capable of delaying operations.

The primary catalyst for this pivot is the clear price signal. With sugar prices currently below the cost of production, mills have a powerful incentive to switch. As one analyst noted, Brazilian sugar mills hedged by taking short positions on the ICE exchange in New York. However, they only hedged a little?more than 20 percent of their anticipated raw sugar sales. This lack of forward pricing leaves producers with the flexibility to respond to real-time market conditions, making the initial production mix a direct function of relative ethanol and sugar prices.

The main risk to this cycle is a reversal in sugar prices. If prices recover and rise above the estimated sugar production cost in Brazil's central-south of around $16.30 per pound, the economic calculus for mills would shift dramatically. As the CEO of Copersucar noted, mills will continuously reassess their mix as and when ethanol and sugar prices converge. A sustained sugar rally could quickly pull cane back into sugar production, undermining the entire pivot thesis.

Another critical variable is the cost of electricity, which is rising structurally. Projections indicate that electricity bills are expected to rise above inflation again in 2026, with estimates ranging from around 5% to 8%. The activation of Brazil's more expensive tariff flags, driven by hydrological risk and the need for thermal generation, will directly increase mill operating costs. This adds a layer of complexity: while higher energy costs improve the relative economics of producing ethanol, they also raise the absolute cost of running the mill. The net effect on profitability will depend on the balance between these two forces.

The bottom line is that the cycle is confirmed by the current price environment and mill flexibility, but it remains vulnerable to a sugar price recovery and is subject to rising input costs. The coming months will test whether the macro pressures are strong enough to sustain the pivot through the entire season.
