The two crops most reliably damaged by El Niño are the two cheapest things in the agricultural complex right now. Cocoa has fallen 19% in 2026 and arabica coffee 30%, both unwinding record highs into rising exchange inventories. Meanwhile the Pacific has just been classified as very strong, with official odds of a historic event at three in four. That gap between the physics and the price is the story.
The Pacific Signal in Numbers
The US Climate Prediction Center's weekly update on 14 September 2026 put the Niño-3.4 sea-surface anomaly at +2.0°C, the threshold for a very strong classification, and lifted the probability of an October–December event exceeding every El Niño since 1950 to 75%, from 69% a month earlier. Subsurface Pacific water is running more than 10°C above average at depth.
The Oceanic Niño Index has travelled from −0.4°C in December–February to +1.8°C in June–August, with the eastern Pacific Niño-1+2 region at +3.7°C. The WMO's seasonal ensemble sees a September–November mean near +3.6°C, a peak in November–December and near-certain persistence into February 2027. On 3 September the WMO said it had never issued an update "so unequivocal".
What the Last Two Events Cost
History sets the scale. Peaks reached +2.1°C in 1982–83, +2.4°C in 1997–98, +2.6°C in 2015–16 and +2.0°C in 2023–24. The most recent episode delivered a record cocoa price of $12,646 a tonne in December 2024, raw sugar at 28.14 cents a pound in November 2023, the highest since 2011, India's rice export ban of July 2023 and the first cancelled anchovy season in Peru's history.
The 2015–16 event cost the world economy an estimated $7.8 trillion in lost productivity, on a Dartmouth study. Munich Re's chief climate scientist Tobias Grimm described the present configuration as "a dangerous mix: as global warming continues, the world is also heading for a Super El Niño".
Mapping Drought Against Flood
| Region | Effect | Commodities exposed | Status, September 2026 |
|---|---|---|---|
| Indonesia, Malaysia | drought, fires | palm oil, robusta, cocoa | fires visible on satellite; palm stocks at 8-month high |
| India, Thailand | weak monsoon | rice, sugar, pulses | monsoon 14% below normal; India importing sugar |
| Australia east and south-east | dry spring | wheat, barley, canola | USDA raised wheat to 31 million tonnes on the current crop |
| Vietnam Central Highlands | dry | robusta | exposure is the 2027/28 flowering |
| West Africa | variable | cocoa | 2026 problem so far is excess rain and black pod |
| Peru, Ecuador coast | floods, warm water | anchovy, fishmeal | anchovy quota cut 36% to 1.9 million tonnes |
| Southern Brazil, Argentina | wet | soybeans, corn benefit; sugar harvest disrupted | Conab has Brazil sugar down 2.9% |
| US southern tier | wetter winter | winter wheat southern edge | Atlantic season: 0 hurricanes by 10 September |
Rabobank's Carlos Mera framed the discipline required: "The mistake would be to treat El Niño as a single weather story. Procurement teams need to map it commodity by commodity and origin by origin."
The Repricing That Already Happened
Sugar was the cleanest expression and the entry has passed. Raw sugar gained 21.5% in August, the largest monthly rise since October 2010, after India, which with Brazil and Thailand supplies about 70% of exports, moved to import 1 million tonnes duty free for the first time in roughly a decade. Indian domestic prices climbed about 40% in two months.
The contract sits near 18 cents, a 17-month high and up 12.6% for the year, with the FAO sugar sub-index adding 11.9% in August alone. The International Sugar Organization models a 2026/27 deficit near 260,000 tonnes; Citi calls sugar its highest-conviction bullish agricultural setup, targeting 19 cents in three months.
Rice followed the monsoon. Indian rainfall from 1 June to 31 August ran 13.8% below normal, August alone 16% below, and the southern peninsula was 27% short by 7 September. USDA's September report cut India's milled rice crop to 147 million tonnes from 154, the first year-on-year fall in ten years, against world output of 533.9 million tonnes. Thai 5% broken rice is $483–485 a tonne and CBOT rough rice is up 35% in 2026.
Palm oil, up about 10% for the year on Indonesia's B50 mandate and the El Niño narrative, is capped near term: Malaysian stocks rose 7.5% in August to 2.82 million tonnes, an eight-month high. The 2015–16 precedent implies output falls with a six-to-twelve-month lag, placing the production hit in 2027.
The Asymmetry in Cocoa
Cocoa's balance is tightening beneath a falling price. StoneX has cut its 2026/27 surplus from 267,000 tonnes in January to about 25,000 in August. Ivory Coast's main crop is seen at 1.35–1.45 million tonnes against roughly 1.6 million, with more than 20% of flowers and cherelles lost to excess rain in May–June, while Ghana's COCOBOD expects a 16% decline and forward sales have slowed.
Exchange stocks sit at a two-year high of 3.44 million bags, yet West Africa and Ecuador supply about 70% of world cocoa, and every significant El Niño in 55 years has cut output. Citi's third-quarter view was a return to $6,000 within a year on West African damage. Hershey guides to "good visibility into cocoa deflation for next year" with a 41.6% gross margin; Mondelez carries a $500 million cocoa charge.
Coffee's Two-Sided Case
Brazil's 2026 crop is a record 66.7 million bags, arabica 45.8 million, and August exports rose 45%, which explains arabica at 286 cents against a 52-week high of 432. Offsetting that, ICE certified arabica stocks are at a 27-year low of 223,712 bags, and the September–October flowering determines 2027 supply.
StoneX's Leonardo Rossetti warns that "El Niño has coincided with both higher and lower Brazilian coffee output in past seasons". Robusta, exposed through Vietnam's dry season, nearly doubled year on year by August on Rabobank's count. Starbucks and Keurig Dr Pepper enjoy a cost tailwind now and inherit the 2027 risk.
Grains Belong to a Different Narrative
Wheat is up 36% in 2026, touching a three-and-a-half-year high of $7.67 on 28 August, with corn up 24% and soybeans 25%. The Pacific deserves little credit. USDA's September report raised world wheat ending stocks to 276.3 million tonnes on larger Russian, Australian and Ukrainian crops, adding 3 million tonnes to Australia at 31 million on "very favorable conditions".
Corn is the exception with a genuine cut: US yield at 178.5 bushels an acre, stocks at 1.567 billion and world stocks at 272.1 million tonnes, India reduced on the monsoon. FAO's August index printed 133.3, up 1.9% on the month, prompting chief economist Máximo Torero to call it "a warning that the risk premium is returning to food markets".
Where the Equity Exposure Sits
Processors and traders such as ADM and Bunge earn on volatility and spreads. Nitrogen names CF Industries and Nutrien benefit as farmers protect yield, with urea already lifted by lost Iranian exports, while Mosaic's potash lags in dry sowing conditions. Tyson and Hormel face feed costs rising with corn, soy and fishmeal.
The cost-takers split by timing. Hershey, Mondelez, Lindt and Barry Callebaut face 2027 cocoa shortage risk against current deflation guidance; Starbucks, Keurig Dr Pepper and JDE Peet's have relief now and flowering risk later. Sugar producers São Martinho, Adecoagro and Shree Renuka re-rated in August. Gas names APA, EQT, Range and EOG face a bearish warm winter, and Allstate, Progressive and Travelers benefit from a quiet Atlantic, with first-half insured losses the lowest since 2020. Broad or single-crop access runs through DBA, MOO, CORN, WEAT, SOYB and CANE.
Sequencing the Risk Budget
Three layers separate the opportunity. Sugar and rice are done for now, the residual upside being a September monsoon below 91% of normal, which the Indian Meteorological Department forecasts. Palm oil and nitrogen form a six-month position with Malaysian stock builds as the headwind. Cocoa and coffee hold the asymmetry: prices down 19% and 30%, stocks high, and a very strong El Niño arriving at the flowering that sets 2027 supply.
Analyst Ruslan Averin would spend the risk budget in that third layer, favouring put options on the cost-takers over outright futures, because futures require the weather to arrive while confectioner guidance only requires it to be feared. The macro overlay compounds it: FAO's index turned up in August, and a central bank fighting energy prices does not need a second front in food.
