Record speculative long positions unwind as weather concerns ease, but stronger ethanol demand and emerging El Niño risks continue to point toward a tighter 2026/27 global balance.
White sugar futures surrendered the bulk of a three week rally this week, with prices sliding to a two and a half week low into Wednesday's close as heavy fund liquidation collided with an unexpectedly encouraging turn in India's monsoon. The retreat came just as the August contract approached its final trading day, a combination that has left the market's near term direction looking considerably more fragile than it did a week ago, even as the medium term case for tighter 2026/27 supply remains largely undisturbed.
Price action through the week was choppy rather than one directional. Both contracts closed lower on Monday, rebounded on Tuesday as Brazil's higher ethanol blend mandate and firmer crude oil lent support, then reversed sharply on Wednesday. That reversal was compounded by positioning risk built up over the prior rally, with a record fund net long position in London white sugar leaving the market acutely exposed to further unwinding.
Monsoon Relief and a Record Long Position Drive the Selloff
The most immediate catalyst for this week's decline was India's weather. India's Meteorological Department reported cumulative monsoon rainfall at 23 percent below normal as of July 15, a marked improvement from the 42 percent deficit recorded as recently as June 30, easing concern over the harvest prospects of the world's second largest cane producer. That improvement builds on an interim reading of 19 percent below normal referenced earlier in the week, itself already a step up from the June 30 baseline.
That easing weather risk met a market already primed for a correction. CFTC Commitment of Traders data for the week ended July 7 showed funds had added 10,368 contracts to their London white sugar net long position, taking it to a record 58,131 contracts, the largest in a data series stretching back to 2011. With the August contract's final trading day approaching, that crowded positioning gave way to heavy liquidation on Wednesday, a dynamic that has historically produced outsized moves once it begins to unwind. Layered on top of these near term pressures is a 2025/26 crop picture that remains comfortably supplied. The International Sugar Organization forecast a record global crop of 182 million tonnes for 2025/26 in May, up 3.5 percent year on year, and lifted its surplus estimate to 2.2 million tonnes from a February projection of 1.22 million tonnes. The USDA's own biannual estimate put global 2025/26 output at a record 186.056 million tonnes.
Ethanol Economics and El Niño Risk Keep the 2026/27 Case Intact
Set against that near term weakness, the fundamental argument for a tighter market in the season ahead has changed little. Brazil's National Energy Policy Council approved raising the mandatory anhydrous ethanol blend in gasoline to 32 percent from 30 percent, a shift that gives mills further incentive to favor ethanol over sugar production. Unica data through May already shows that reallocation underway, with the share of Center South cane directed to sugar falling to 41.42 percent from 50.09 percent a year earlier, while the ethanol share rose to 58.38 percent from 49.91 percent. Czarnikow responded by cutting its global 2026/27 balance estimate from a surplus of 1.4 million tonnes to a deficit of 100,000 tonnes, citing mills favoring ethanol amid elevated crude prices, a shift reinforced this week as WTI crude rose more than 9 percent on Monday to a three and a half week high before adding a further 1 percent on Tuesday.
El Niño remains the other pillar of the bullish medium term case. The US Climate Prediction Center has flagged that the emerging pattern could rank among the strongest in more than 75 years, with the potential to curb rainfall across Brazil, India and Thailand alike. India's weather office has already cut its June to September monsoon estimate to 90 percent of the long term average, and the Earth Science Ministry has warned this could be the weakest monsoon in 11 years. The ISO projects global 2026/27 production falling 1.15 percent year on year to 180 million tonnes, producing a deficit of 262,000 tonnes, while StoneX forecasts a deficit of 550,000 tonnes and the USDA sees output falling 6.5 percent to 184.854 million tonnes, with Thailand's crop down 15.6 percent and Brazil's down 3.0 percent.
