Sugar futures rallied sharply in the latest session as concerns over a potentially powerful El Niño weather pattern added to existing supply-side risks. March New York raw sugar rose 2.96% to settle at 20.87 cents per pound, while December London white sugar advanced 3.35% to 562.00 per tonne, based on the supplied closing changes and prices.

The rally reflects growing concern that adverse weather could disrupt sugar production across Brazil, India and Thailand, three of the world’s most important sugar-producing and exporting regions. Further rainfall in Brazil’s Center-South region could delay harvesting and cane crushing, while below-normal Indian monsoon rainfall adds uncertainty to the next production cycle.

The outlook is becoming increasingly sensitive to weather developments, harvest progress and revisions to global supply estimates. Although forecasts for a 2026/27 deficit provide support, the market still faces uncertainty over the size of the potential shortfall and the extent to which existing inventories can absorb production losses.

Market Snapshot

Price changes and market estimates are based on the supplied source material. Global balance forecasts differ materially between organisations and remain subject to revision.

1. El Niño Raises the Risk of Weather-Related Supply Disruption

Weather expectations are becoming a central driver of sugar prices. Japan’s Meteorological Agency has reported unusually elevated tropical Pacific temperatures, while US climate forecasters have warned that the developing El Niño could become one of the strongest in decades.

A strong El Niño can alter rainfall patterns and temperatures across major agricultural regions. For sugar, the implications depend on the location, timing and severity of those changes. Drought can reduce cane yields and sugar content, while excessive rainfall can disrupt harvesting, transport and processing.

Brazil is particularly important because it is the world’s largest sugar producer. Forecasts for intensified rainfall in the Center-South region raise the possibility of further delays to harvesting and crushing. If these disruptions persist, the amount of sugar reaching the market could fall short of expectations.

However, weather forecasts alone do not confirm a sustained production decline. The market will need to assess actual rainfall, field conditions, mill operations and updated crop estimates before pricing in a more severe global shortage.

2. Brazil’s Harvest Progress Remains a Key Price Driver

Brazil’s sugar industry is a major influence on global availability, and recent production figures have highlighted the market’s sensitivity to weather disruptions. The supplied data indicate that Center-South sugar production fell 26.3% year on year in June to 3.903 million tonnes.

That decline provides a reminder of how quickly adverse operating conditions can affect output. Continued rain could slow harvesting and reduce the pace at which mills process sugar cane, tightening near-term availability.

Crude oil prices also matter because Brazilian mills can allocate more cane towards ethanol rather than sugar, depending on relative returns. If energy prices strengthen sufficiently, ethanol production may become more attractive and limit the amount of cane directed towards sugar.

The balance between rainfall, milling activity and ethanol economics will therefore remain central to the next phase of the market. A recovery in crushing rates could ease some of the current supply concerns, while prolonged disruption would strengthen the case for further gains.

3. India and Thailand Add to the Supply Concerns

India’s production outlook is another important consideration. The supplied figures show cumulative monsoon rainfall was 12.6% below normal by the end of September, the weakest reading in 11 years according to the cited report.

Lower rainfall can affect cane development and future yields, although the eventual impact depends on regional conditions, irrigation, soil moisture and the timing of subsequent rainfall. India’s sugar availability is especially important because domestic consumption is substantial and export volumes can change depending on local supply.

India’s decision to permit up to one million tonnes of raw sugar imports without taxes until October 31 also points to concern about domestic supply availability. As India is usually a significant exporter, a shift towards imports can affect the amount of sugar available to the international market.

Thailand presents a further risk. The Thai Sugar Millers Corp has projected that 2026/27 production could fall to around 10 million tonnes, a decline of 17% year on year. Other forecasts also anticipate a sizeable reduction.

If production falls in both India and Thailand while Brazilian harvesting remains disrupted, global exporters could face a tighter supply outlook. Nevertheless, the scale of the impact will depend on actual crop results, domestic consumption and any changes to export policy.

4. Global Sugar Balance Forecasts Remain Divided

The longer-term supply picture is supportive, but the estimates vary considerably.

The International Sugar Organization has forecast a global surplus of 1.1 million tonnes for 2025/26, following a deficit in the previous season. For 2026/27, it projects production falling to approximately 180.1 million tonnes and a deficit of around 200,000 tonnes.

Other organisations have issued different projections. StoneX has estimated a considerably larger deficit, while Covrig Analytics has also revised its outlook as expectations for production and consumption have changed. Czarnikow has highlighted the possibility of a more substantial deficit in 2027/28.

These differences matter because sugar prices respond not only to whether the market is expected to move into deficit, but also to the size of that deficit relative to inventories and consumption. A small projected shortfall may have a limited effect if stock levels remain comfortable. A larger production shortfall, combined with falling inventories, would provide a stronger basis for a sustained rally.

There is also a counterweight to the bullish narrative. The ISO expects a record crop and a surplus in 2025/26, while USDA estimates in the supplied material point to relatively high ending stocks for 2026/27. Differences in reporting periods and forecasting assumptions mean these estimates should not be treated as directly interchangeable.

For traders, updated crop forecasts and inventory data will be important in determining whether the recent rally reflects a temporary weather premium or the beginning of a more persistent tightening in global supply.

5. Fund Positioning Could Amplify Price Swings

Speculative positioning is another factor supporting the market. The supplied Commitment of Traders data show that funds increased their net-long New York sugar positions by 60,442 contracts in the week ended October 6, taking the net-long position to 212,559 contracts.

A large net-long position indicates that speculative investors are positioned for higher prices. This can help sustain upward momentum when new bullish information emerges, particularly if weather forecasts deteriorate or production estimates are reduced.

However, crowded positioning also creates a risk. If rainfall improves, harvest delays ease or forecasts shift back towards a global surplus, funds may reduce exposure. A wave of long liquidation could accelerate a correction even if the underlying supply-demand balance remains relatively tight.

The market is therefore vulnerable to sharp moves in both directions as traders respond to weather updates and revisions to crop estimates.

Technical Outlook: Sugar Futures

The latest rally strengthens the near-term bullish tone in both New York raw sugar and London white sugar. However, the supplied data do not provide enough verified chart information to establish reliable current support and resistance levels.

The next technical assessment should focus on whether prices can hold the gains from the latest session and build on the recent advance. Follow-through buying would suggest that the market is accepting the tighter-supply narrative. A failure to maintain the rally could indicate that speculative positioning and weather concerns have already been substantially priced in.

Bullish scenario

Sugar prices could extend their gains if rainfall continues to disrupt Brazilian harvesting, crushing activity remains weak and forecasts for India and Thailand are revised lower. Evidence of declining inventories or a larger 2026/27 deficit would reinforce this scenario.

Bearish scenario

Prices could retreat if Brazilian mills improve their operating pace, weather conditions become more favourable or production estimates recover. A reduction in speculative long positions could amplify the decline, particularly if updated balance estimates point to adequate global stocks.

Neutral scenario

Sugar may consolidate after the sharp rally while the market waits for clearer evidence of crop damage and harvest disruption. In this scenario, short-term price swings could remain pronounced without establishing a sustained directional trend.

Sugar Price Forecast: Outlook for the Coming Sessions

The near-term outlook is cautiously bullish, with weather risk providing the principal source of support. The combination of potential Brazilian harvest delays, below-normal Indian monsoon rainfall and weaker Thai production expectations creates a credible risk that global supply will tighten during the next crop cycle.

The immediate focus will be on rainfall across Brazil’s Center-South region and whether mill activity can recover. Further disruption could encourage additional buying, especially while speculative positioning remains supportive.

Attention will also turn to updated production estimates and evidence of how much sugar will be available for export from India and Thailand. If these developments confirm a widening global deficit, the rally could gain further momentum.

However, the market is not without downside risk. Forecasts for the global sugar balance remain divided, existing stock estimates offer some cushion, and heavily net-long fund positioning could leave prices exposed to profit-taking.

Over the coming sessions, sugar is likely to remain sensitive to weather forecasts, harvest progress and changes in speculative exposure. A sustained advance will require confirmation that production risks are translating into tighter physical availability rather than relying on weather expectations alone.

Analysis — Louis Roche, Today Markets

Sugar is increasingly being priced as a weather-sensitive commodity, with the potential for El Niño to disrupt production across several major growing regions. Brazil remains the key near-term variable because rainfall can affect both the timing of harvesting and the volume of cane processed by mills.

The broader outlook is constructive for prices if the expected production declines in India and Thailand materialise and Brazil experiences further disruption. Yet the size of the projected global deficit remains uncertain, and a forecast shortfall should not be confused with a confirmed physical shortage.

The next phase of the rally will depend on whether weather risks translate into measurable reductions in output and export availability. Until that evidence becomes clearer, the balance of risks favours a cautiously bullish but volatile market rather than an uninterrupted upward trend.

Currency Hedger View

Sugar is influenced by more than agricultural conditions. Crude oil prices can affect the economics of ethanol production in Brazil, while currency movements can alter producer revenues and export competitiveness. Weather disruptions, trade policy and global demand also shape the price outlook.
