The Forecastable Shock: What the Forward Curve Has and Hasn't Priced for 2027
By Rebecca Osei, Head of Trade & Development Economics
Most supply shocks arrive without warning. The one now building in the equatorial Pacific has published its own advance notice. The latest ENSO diagnostic discussion from the US National Oceanic and Atmospheric Administration (10 September 2026, El Niño Advisory in effect) puts a greater-than-90% chance on a very strong El Niño through the Northern Hemisphere autumn and winter, and 75% odds that the October–December peak proves historic — exceeding every event since 1950. The World Meteorological Organization, in a separate assessment on 3 September, sees a near-100% likelihood that El Niño persists through February 2027, strengthening to very strong intensity before peaking late this year. Two probabilities — strength and persistence — and one unusually legible calendar.
Forward markets, however, are pricing this as four separate commodity stories rather than one class of risk. That gap is the decision. We have argued before that early-warning capability pays off only inside the notice period; this is the live worked example. The task for procurement and finance leaders is a triage — sorting every 2027 input exposure into fully priced, partially priced or unpriced — completed before Southern Hemisphere planting, from October, converts forecast into fact.
Cocoa: Already in the Price
Cocoa anchors the "fully priced" end. PricePedia reports that international quotations have risen more than 70% since February 2026, averaging above US$5,500 per tonne in early September, on deteriorating supply expectations and rising El Niño probability: drought stress across Côte d'Ivoire and Ghana, roughly 60% of global supply, and flood risk in Ecuador, the third-largest producer. Forecasts compiled by PricePedia put the 2027 average around 12% above 2026's; Consensus Economics sees just above US$5,000 per tonne by December 2027 — modestly below current levels. In our reading, the El Niño premium is largely in the price. That is not the same as historically expensive — 2026 still averages more than 40% below 2025's peaks above US$8,200 per tonne — but it does mean chasing the market now buys last season's news.
Palm Oil: The Lag the Curve Has Only Partly Caught
Palm oil is the centre of the 2027 story because its transmission is slow. Purdue University's analysis of converging vegetable-oil pressures notes that El Niño's yield impact builds over a 6–24-month lag: the June–September 2026 drought-stress window across Indonesia and Malaysia — together roughly 90% of global supply — will not fully express until 2027. The same analysis flags demand tightening simultaneously, as Indonesia's B50 biodiesel mandate absorbs a growing share of domestic output.
The curve has begun to respond. Bursa Malaysia's November 2026 contract closed at RM4,931 per tonne on 4 September, per Palm Oil Magazine reporting, with gains attributed to El Niño production concerns, and early-September forward months out to February 2027 traded around RM5,000–5,150 against nearby months in the low-RM4,600s — a calendar premium of roughly 10%, in our reading. Whether 10% covers a stress event whose yield consequences run through the whole of 2027, compounded by mandated biodiesel demand, is doubtful. Our interpretation: partially priced, with the gap concentrated in late 2027.
Grains: Thin Buffers and No Premium
The grain complex is where insurance is cheapest — because nothing is priced. USDA's September WASDE, released on 11 September and reported by DTN, cut US 2026/27 corn ending stocks by 86 million bushels to 1,567 million, lowered US soybean ending stocks to 310 million bushels from 320 million, and trimmed world corn and soybean stocks to 272.1 and 124.0 million tonnes respectively. These are balance-sheet revisions, not weather: no South American premium sits in these numbers, because that season has not begun.
Honesty requires the two-sided framing. El Niño's South American signal is historically mixed — often wetter, sometimes beneficially so, in Argentina and southern Brazil, drier in northern Brazil — with planting-window disruption from October the nearest-term channel. The defensible claim is not that corn and soybean prices must rise; it is that the buffer that would absorb a Southern Hemisphere problem is now materially thinner, so tail sensitivity has risen while the curve carries no premium for it. Unpriced risk, not a directional forecast.
The Triage: One Shock, Three Pricing States
Each commodity's status differs for one reason: biological and geographic lag structure — same shock, different transmission speeds. A buyer pricing exposures one desk at a time will systematically buy the lagged exposures late, after they converge with cocoa. It is the same composition-versus-headline discipline we applied to this year's trade figures: the aggregate "food commodities" story conceals three different pricing states. The status column below is our interpretation of public forward prices, not a statement of fact.
| Commodity | Key producing regions | Impact channel and lag | Price move since Feb 2026 | Forward-curve status (our interpretation) | Recommended action |
|---|---|---|---|---|---|
| Cocoa | Côte d'Ivoire and Ghana (~60% of supply); Ecuador third | West African drought, Ecuadorian floods; short lag, already in spot | Up more than 70%; above US$5,500/t average in early September | Largely priced — 2027 consensus modestly below current levels | Do not chase; cover residual 2027 volume only; watch Oct–Dec main-crop arrivals |
| Palm oil | Indonesia and Malaysia (~90% of supply) | Drought cuts yields on a 6–24-month lag; 2026 stress expresses through 2027 | Rising: Nov-26 up to RM4,931/t on El Niño concerns; Feb-27 months near RM5,150 (~10% over nearby) | Partially priced — modest premium against a full-year yield drag plus biodiesel demand | Extend first-half 2027 cover now; test substitution headroom before soft oils reprice |
| Corn | United States, Brazil, Argentina, Ukraine | South American planting disruption from October; historically two-sided for Argentina | No weather premium in the curve; US ending stocks cut to 1,567m bushels, world stocks to 272.1 MMT | Unpriced — cuts to date are balance-sheet arithmetic, not weather | Buy optionality: floors or collars on 2027 feed and starch exposure before October |
| Soybeans | Brazil, United States, Argentina | Same planting channel; soy oil inherits vegetable-oil tightness via the crush | No weather premium in the curve; US ending stocks 310m bushels, world 124.0 MMT | Unpriced — the soy-oil leg carries the added vegetable-oil asymmetry | Split the exposure: cover the oil leg earlier than meal and beans |
What Could Overturn This Reading
- The forecast itself. NOAA's 75% is a probability, not a certainty; a peak-and-fade toward moderate intensity by early 2027 would leave the unpriced legs correctly unpriced. The monthly diagnostics are the checkpoint.
- A benign South American season. El Niño has favoured Argentine yields in past events; smooth planting and large Brazilian and Argentine crops would rebuild world stocks and vindicate the flat curve.
- Policy moving faster than weather. Indonesia's B50 timing, and any export-levy response to domestic cooking-oil prices, can shift 2027 palm balances as much as yields. Watch whether the October and November WASDE rounds begin embedding South American weather — the first sign the unpriced leg is repricing.
What This Means for Decision-Makers
- Run the triage before October, as ordinary procurement hygiene. Classify every 2027 input exposure as fully, partially or unpriced against its lag structure. The classification, not a price view, drives the action: chase nothing fully priced, extend cover on the partially priced, buy optionality on the unpriced.
- Buy optionality where the curve is flat, not where the news is loud. Cocoa headlines are the rear-view mirror; corn and soybean options are cheap because no premium exists yet — and optionality fits a two-sided South American risk better than fixed-price contracts.
- Treat the vegetable-oil complex as one exposure. Palm tightness plus biodiesel demand transmits into soybean, rapeseed and sunflower oil through substitution; a buyer "diversified" across vegetable oils holds one correlated 2027 position.
- Timestamp the decision. The value of acting on a forecast decays on a known calendar — October planting, the October–December strength window, the February 2027 persistence horizon. Institutionalise the review date, not just the trade.
