Sugar prices sink as ethanol weakness may spur more sugar production

Sugar futures settled sharply lower on Wednesday: July NY World Sugar #11 (SBN26) closed down -0.56 (-3.64%) and August London ICE White Sugar #5 (SWQ26) fell -15.00 (-3.32%), with London trading at a one‑week low.

A key driver was a roughly 4% plunge in RBOB gasoline futures, which undercut ethanol prices and weighed on sugar by eroding biofuel margins; when ethanol weakens, mills can reallocate crushing toward sugar, altering near‑term supply dynamics.

Data from Brazil—central to global sugar balances—adds to the mix. The Brazilian National Supply Company (Companhia Nacional de Abastecimento – Conab) provided an initial 2026/27 outlook showing only a slight decline in total sugar output, while UNICA (Brazilian Sugarcane and Bioenergy Industry Association) reported a year‑on‑year 11.9% drop in Center‑South sugar production in the first half of April, reflecting a swing in the crush mix. These figures support the argument that production choices at mills remain a major near‑term supply factor.

At the global level, official balances from the US Department of Agriculture (USDA) previously pointed to comfortable production, but private forecasters such as Green Pool have cut surplus estimates and even project a deficit for 2026/27, a divergence that leaves markets sensitive to weekly and monthly supply updates. Geopolitical disruptions affecting shipping lanes have also been cited as a potential constraint on refined sugar flows.

Market strategists say the outlook hinges on fuel markets and forthcoming crop/processing reports: if gasoline recovers and ethanol parity improves, mills may favor ethanol and tighten sugar supplies, lifting prices; conversely, larger-than-expected production from Brazil or increased Indian exports would prolong the down‑trend. Traders should monitor weekly UNICA crush reports, Conab releases and USDA balance revisions for trading signals.
