For the first time since the record-breaking event of 2023–24, forecasters are again flashing an El Niño warning — and the world’s tropical commodity markets are paying close attention. On June 11, 2026, NOAA’s Climate Prediction Center upgraded its outlook to an El Niño Advisory, confirming that conditions are present and expected to strengthen through the Northern Hemisphere winter. For coffee, cocoa, sugar, and palm oil — crops grown almost entirely in the narrow band of the tropics where El Niño does its damage — that forecast is more than a weather headline. It is a supply-side variable that systematic traders, managed-futures programs, and commercial hedgers all have to price.
Here is what the forecast actually says, why these four markets are so sensitive to it, and how traders and hedgers tend to approach a developing El Niño.
What the forecast actually says
An El Niño is the warm phase of the El Niño–Southern Oscillation (ENSO), defined by unusually warm sea-surface temperatures across the central and eastern equatorial Pacific. In its June 11, 2026 diagnostic discussion, the Climate Prediction Center reported that the key Niño-3.4 region had warmed to roughly +0.7°C above average, with the far-eastern Niño-1+2 region running far hotter still. Crucially, CPC put the odds of the event becoming a very strong El Niño — one that would rank among the largest since reliable records began in 1950 — at about 63% for the November–January peak.
That distinction matters. Weak El Niños come and go with little agricultural consequence. Strong ones reorganize rainfall across the entire tropical belt: drought in Southeast Asia and parts of West Africa, erratic monsoons over India, and shifting patterns across Brazil. The June advisory does not guarantee a strong event, and CPC will update its view in its next discussion in July. But a 63% probability of a top-tier El Niño is exactly the kind of skew that supply-sensitive markets begin to discount months ahead of the physical impact.
Why El Niño moves coffee, cocoa, sugar, and palm oil
Three features make these particular markets so reactive. First, production is geographically concentrated — a handful of countries near the equator grow the overwhelming majority of the world’s supply, so a regional weather shock is effectively a global one. Second, these are perennial or seasonal tree and cane crops with long lags: heat and drought stress during a critical growth window can suppress output six to twelve months later, well after the El Niño itself has faded. Third, demand is highly inelastic. People do not stop drinking coffee or eating chocolate because prices rise, so even a modest supply deficit can translate into an outsized price move.
The 2023–24 El Niño offered a textbook demonstration of all three. Below, each market in turn.
Coffee: robusta is the front line
Coffee splits into two beans with very different weather exposures. Arabica, grown heavily in Brazil and Colombia, is the premium bean; robusta, the hardier, more caffeinated bean used in instant coffee and espresso blends, is dominated by Vietnam — the world’s largest robusta producer — with Indonesia close behind. Both Southeast Asian growers reliably dry out during El Niño.
In 2023–24 that dryness arrived on schedule. Vietnam’s agriculture ministry projected its crop could fall roughly 20% to its smallest in four years, and robusta futures responded by climbing to multi-decade highs — their loftiest levels since at least 2008, with arabica dragged up alongside. A strengthening 2026–27 event puts the same Vietnamese and Indonesian growing regions back in the crosshairs, which is why coffee is one of the first softs to attract speculative positioning when an advisory is issued.
Cocoa: the most weather-sensitive of all
Cocoa may be the single most El Niño-sensitive commodity on the board. Roughly two-thirds of the world’s cocoa comes from a small cluster of West African nations — Ivory Coast, Ghana, Nigeria, and Cameroon — where hot, dry conditions during the main-crop establishment window, which begins around October, can sharply curtail yields. Analysts have noted that essentially every strong El Niño of the past half-century has coincided with reduced global cocoa production.
Traders need no reminder of the stakes. The 2023–24 season’s West African crop failure sent cocoa nearly tripling to records above $12,000 per tonne by late 2024 — briefly making a soft agricultural commodity more valuable than several industrial metals. Prices have since come well off those extremes, with New York cocoa spiking near $4,700 per tonne this past May before easing. With a potentially very strong El Niño overlapping the next main-crop window, the market enters the 2026–27 season with little tolerance for another weather disappointment.
Sugar: monsoon-dependent and export-sensitive
After Brazil, the world’s two largest sugar exporters are India and Thailand — and both depend on monsoon rains that El Niño tends to weaken. The 2023–24 event made the linkage vivid. India recorded its driest monsoon in five years, sugar output fell roughly 11% year over year, and New Delhi imposed export restrictions to protect domestic supply. Thailand fared worse still, with production collapsing by more than a third to a multi-year low. Global sugar prices climbed to their highest since 2011.
Sugar carries an added wrinkle: it competes with ethanol. When cane is diverted to biofuel, or when major producers restrict exports for food-security reasons, the supply available to the world market tightens further — effects that can amplify a weather-driven deficit. A strengthening El Niño reintroduces all of these variables at once.
Palm oil: the long-lag trade
Palm oil is the world’s most consumed vegetable oil, and its production is concentrated even more tightly than cocoa’s — Indonesia and Malaysia together account for the large majority of global supply. The El Niño effect here is real but slow. Oil palms stressed by drought produce fewer fresh fruit bunches, but the yield hit typically shows up six to twelve months after the dry period, as the trees’ reproductive cycle catches up to the weather.
That lag makes palm oil a market where the El Niño thesis plays out over quarters rather than weeks, and where the timing of the price response is as important as the direction. It also ties palm oil to the broader edible-oils complex, so a Southeast Asian supply scare can ripple into soybean oil and other substitutes.
What it means for systematic traders
For trend-following and other systematic managed-futures programs, a developing El Niño is not a forecast to trade on directly — it is a backdrop that tends to produce exactly the conditions these strategies are built to capture: sustained, fundamentally driven moves in markets that often have little to do with equities or bonds. The softs complex has historically been a source of valuable diversification precisely because its return drivers — weather, harvests, regional politics — are largely uncorrelated with the macro forces that move financial futures.
A systematic trader does not need to predict whether the 2026–27 event peaks as strong or very strong. The discipline is to let price and trend signals do the work: if El Niño tightens cocoa or coffee supply, the resulting trend is something a rules-based program can participate in on either side, long or short, without taking a discretionary weather bet. The caution is equally important — weather is not destiny, markets often price an expected El Niño months in advance, and the lags between a forecast and an actual crop shortfall leave plenty of room for false starts and sharp reversals.
What it means for hedgers
For the commercial side — roasters, chocolate manufacturers, sugar refiners, food companies, and the producers who supply them — an El Niño advisory is a risk-management prompt. A confectioner staring at a 63% chance of a very strong event over the next cocoa main crop has a concrete reason to revisit how much of its forward input cost is locked in. The same logic runs the other way for a producer who wants to protect a favorable price against the possibility that the event fizzles and supply recovers.
Futures and options exist precisely so that these participants can transfer weather risk rather than absorb it. The goal of a well-built hedge is not to predict the weather but to remove it as a source of uncertainty in the budget — converting an unknowable crop outcome into a known, manageable cost.
How Wisdom Trading approaches it
Wisdom Trading sits on both sides of this picture. We provide direct-access execution and competitive commissions for traders active in the softs and broader commodity markets, we work with established systematic and managed-futures programs that trade these markets as part of a diversified portfolio, and we advise commercial clients on building hedging structures appropriate to their exposure. A developing El Niño is a reminder of why those markets exist in the first place — and why having an experienced, independent broker matters when conditions get volatile.
If you trade the softs complex, run a systematic program that includes these markets, or carry commercial exposure to coffee, cocoa, sugar, or palm oil, we are happy to talk through execution and hedging options as the 2026–27 ENSO picture develops.
