Sugar Market Tightens as ISO Slashes Surplus and Flags El Niño Risk

The global sugar market has shifted rapidly from a comfortable surplus narrative toward a finely balanced and weather‑sensitive outlook, with prices already reacting to the tighter fundamentals. After several downward revisions, the International Sugar Organization now sees only a marginal surplus in 2025/26 and a small deficit in 2026/27, leaving far less buffer against crop or logistical shocks. At the same time, European wholesale prices in EUR are firm to slightly higher and futures on ICE have rallied to a 16‑month high on renewed supply concerns. Against this backdrop, a strengthening El Niño with high probability of becoming a very strong event into late 2026 materially raises production risks for Brazil, Thailand and the EU, increasing procurement risk for buyers and supporting price resilience despite ISO’s view that the latest rally is somewhat ahead of fundamentals.

Prices

ISO reports that the ISA Daily Price averaged 17.4 US cents/lb in August, reflecting a strong rally in raw sugar futures as markets priced a much tighter balance. Converting roughly at 1 EUR = 1.10 USD, this implies an average world raw sugar level near 343 EUR/tonne. Spot market strength has extended into early September, with ICE raw sugar futures reaching around 18.7 cents/lb, their highest level in about 16 months, driven by worries over Brazil’s harvest performance and tightening global availability.

In Europe, physical quotations for refined white sugar remain firm, with FCA offers mostly in a 0.49–0.65 EUR/kg band depending on origin and specification. Recent quotes include around 0.58 EUR/kg for UK and Czech refined sugar, 0.49 EUR/kg for Ukrainian origin in Central Europe, and about 0.65 EUR/kg for German product into Berlin. Compared to mid‑August, most listings are steady to slightly higher, confirming that the futures‑led rally and tighter global balance are supporting regional wholesale prices in EUR terms.

Supply & Demand Balance

The International Sugar Organization has cut its 2025/26 global sugar surplus forecast to just 1.1 million tonnes, down from 2.2 million tonnes in May and marking the fourth downgrade this season. The revision is driven primarily by weaker‑than‑expected output in Brazil’s Centre‑South region in the first half of the crushing season, underlining Brazil’s role as the dominant swing producer able to adjust between sugar and ethanol.

Despite a robust recovery in China, where ISO now estimates sugar production at nearly 13 million tonnes—the highest since 2013/14—the additional Chinese output has only partially offset Brazil’s shortfall. On ISO’s latest numbers, the 2026/27 season is expected to show global production of about 180.1 million tonnes and consumption of 180.4 million tonnes. This implies a small deficit of roughly 0.2–0.3 million tonnes after balance‑sheet adjustments, confirming that the global market is transitioning from modest surplus to slight structural shortfall.

Outside Brazil, ISO expects sugar production to fall by around 4.4 million tonnes in 2026/27, with the largest declines concentrated in the European Union, Thailand and Central America. This prospective contraction leaves Brazil even more central to the world supply picture. If multiple non‑Brazilian origins underperform simultaneously, the global market would become increasingly dependent on Brazilian mills expanding sugar output, significantly heightening the sensitivity of prices to Brazil’s cane allocation decisions and any harvest or logistical disruptions.

Fundamentals: Brazil, China, EU & Thailand

Brazil as swing producer. Early‑season data for the Centre‑South show a notable decline in cane throughput versus last year, with June milling down by roughly 14–15% year‑on‑year as some mills delayed crushing and field yields softened. Nonetheless, recent gains in sugar futures have improved the relative economics of sugar over hydrous ethanol, incentivising mills to shift a greater share of cane to crystal sugar in coming months. This flexibility could partially offset the weak first‑half performance and some of the 4.4‑million‑tonne drop expected outside Brazil.

China’s recovery. China’s nearly 13‑million‑tonne crop, the highest in over a decade, boosts domestic availability and trims import needs, marginally easing global tightness. However, even with this recovery, ISO’s repeated downgrades to the world balance show that Chinese strength cannot fully compensate for weakness in Brazil, the EU and Thailand at current demand growth rates. Any weather‑related setback in China during 2026/27 would therefore exacerbate a balance that is already projected to be in slight deficit.

EU and Thailand under pressure. ISO’s outlook assumes meaningful output declines in both the EU and Thailand for 2026/27. In Europe, beet area and yield risk are elevated amid regulatory uncertainty, disease pressure and rising input costs, while Thailand’s cane sector faces persistent weather and profitability challenges. Together with anticipated declines in Central America, these regions account for the bulk of the expected 4.4‑million‑tonne drop outside Brazil, reinforcing the theme of a narrower and more geographically concentrated supply base.

Weather & El Niño Risk

Weather risk is now the single biggest uncertainty for the sugar outlook. ISO explicitly flags the current El Niño as the main threat to 2026/27 production, with the event potentially becoming one of the strongest on record. Recent assessments from global meteorological agencies confirm that El Niño has strengthened through mid‑August, with forecasts pointing to a very strong event and near‑100% probability it will persist through at least February 2027.

For the September–November 2026 period, seasonal outlooks project further intensification of El Niño conditions, with Niño‑3.4 sea‑surface temperature anomalies potentially exceeding 3°C as the event peaks around late 2026. Historically, such strong episodes have been associated with altered rainfall and temperature patterns in key cane and beet regions, including Brazil, Southeast Asia and parts of Europe. In Brazil, current guidance suggests above‑average rainfall in parts of the Centre‑South and drier‑than‑normal conditions in the North and Northeast, while much of the tropics and subtropics face elevated heat stress—conditions that could pressure cane yields and harvesting logistics if extremes materialise.

This evolving climate backdrop magnifies the downside risk around ISO’s relatively modest 0.2‑million‑tonne deficit projection for 2026/27. Any combination of drought, excessive rainfall or prolonged heat affecting Brazil, Thailand or the EU could quickly flip the balance into a materially larger global shortfall, providing additional justification for the recent price rally and supporting volatility in both futures and physical premiums.

Market Outlook & Trading View

The tightening of the global balance—from a 2.2‑million‑tonne surplus expected in May for 2025/26 to just 1.1 million tonnes now, and a projected 0.2‑million‑tonne deficit in 2026/27—marks a regime shift for the sugar market. Even though ISO judges the latest price rally to 17–19 cents/lb as somewhat premature relative to current fundamentals, the smaller cushion against weather or policy shocks implies that risk premia are likely to remain embedded in prices. The market has effectively moved into a high‑beta phase where incremental news on Brazilian cane allocation, El Niño developments, and EU/Thailand crop conditions could trigger outsized price reactions.

For importers, the combination of tighter fundamentals and escalating climate risk materially increases procurement risk. A modest deficit and thinner exporter base reduce flexibility to cover unexpected demand or origin‑specific problems, particularly if logistics or policy interventions emerge in key suppliers. For exporters and mills, by contrast, firmer prices and strong white‑raw spreads improve margins and strengthen the incentive to maximise sugar output where agronomic conditions permit. In Brazil, this is likely to translate into higher sugar‑to‑ethanol allocation in 2026/27, while in the EU and Thailand the scope for supply response is more constrained by structural and weather‑related factors.

Focused Trading Recommendations

• Importers / industrial users: Consider layering in medium‑term cover on price dips rather than relying on spot, given the compressed surplus and elevated El Niño risk into early 2027. Prioritise diversified origin exposure (Brazil, EU, Thailand, Ukraine) to mitigate regional weather and policy shocks.
• Refiners and distributors in Europe: With FCA refined prices broadly stable to slightly higher around 0.50–0.65 EUR/kg and global futures at multi‑month highs, hedge forward sales selectively, focusing on locking margins where input and energy costs are known. Maintain some unhedged volume to benefit from potential further upside if El Niño significantly curbs 2026/27 output.
• Producers / mills in Brazil and other exporters: Current futures levels and ISO’s tight balance projections favour a bias toward higher sugar production over ethanol where logistics and credit permit. However, retain flexibility in cane allocation decisions to respond if energy prices or policy shifts improve ethanol returns later in the season.

3‑Day Directional Price Indication (EUR terms)

• ICE raw sugar (world market, EUR/tonne equivalent): Bias moderately upward/volatile over the next 3 days, with strong El Niño headlines and tight ISO balance likely to keep prices supported near recent highs.
• European refined sugar, FCA (EUR/kg): Expect broadly steady to slightly firm indications around 0.50–0.65 EUR/kg as physical sellers test higher offers but buyers resist rapid follow‑through after August increases.
• Regional Central European quotes (CZ, UA, LT): Prices near 0.49–0.58 EUR/kg likely to hold, with limited downside given global fundamentals; modest upside possible if futures extend gains or if regional logistics tighten.
