Official agencies now broadly expect El Niño to develop in 2026. But for the cashew market, the real risk is not a guaranteed global supply shock. It is a tighter margin for error across Asia, Africa and Brazil at the same time.
Recent headlines about a possible “Super El Niño” have started to attract attention across agricultural markets. For cashew buyers, processors and traders, the question is not only whether El Niño will develop, but how it could affect the main origins of raw cashew nuts and kernels.
The current evidence points to a clear but nuanced conclusion. El Niño development in 2026 is now broadly considered the base case by official forecasting agencies. NOAA’s latest outlook places the chance of El Niño at 82% for May–July 2026 and 96% for December 2026–February 2027. Other agencies, including JMA, WMO, BoM and ASMC, also point toward El Niño development from mid-2026 onward.
However, the strength of the event remains less certain. This is where some market headlines risk going too far. The widely circulated “65% chance” appears to refer to the combined probability of strong plus very strong El Niño conditions around November 2026–January 2027. That is not the same as saying there is a 65% chance of a “Super El Niño.”
WMO and the UK Met Office do not use “Super El Niño” as an official operational category. NOAA also communicates in terms of strength probabilities rather than “super” status. For commodity markets, that distinction matters. A strong El Niño would not automatically mean a supply shock, but it would make the market more weather-sensitive, especially if several origin risks overlap during the same season.
Why El Niño matters for cashews
El Niño is the warm phase of the El Niño–Southern Oscillation, a Pacific Ocean climate pattern that can influence rainfall, heat, drought and flood risk across many parts of the world. Its impact is not the same everywhere. In some regions it can bring dryness and heat; in others it can increase rainfall or logistics risk.
Cashews are particularly sensitive to timing. The crop can be damaged by too much rain and humidity during flowering, which may increase flower drop, fruit drop and fungal disease. But too little rain and excessive heat during the reproductive stage can also reduce fruit set, nut number, nut weight and overall yield.
Once nuts are ready for harvest, drier weather can sometimes be beneficial. It can improve field drying, lower moisture risk and support quality. That means the key question is not simply whether El Niño brings “dry” or “wet” weather. The real question is which crop stage is exposed when the anomaly arrives.
Southeast Asia: the clearest risk area
Vietnam and Cambodia stand out as the clearest cashew-market exposure in the current outlook.
ASMC explains that El Niño typically brings drier and warmer conditions to Southeast Asia, with stronger impacts during moderate or strong events. Historical Mekong-region analysis also links El Niño with reduced rainfall in the Lower Mekong during June–September.
This matters because Cambodia has become an important raw cashew supplier into Vietnam, while Vietnam remains the central processing hub of the global cashew industry.
If Vietnam and Cambodia experience materially hotter and drier conditions, local raw cashew availability could come under pressure. Flowering, nut fill and local crop development are the main areas to watch. Drier harvest weather could still help with drying and moisture control, but if dryness hits too early or lasts too long, the negative effect on crop formation could outweigh the post-harvest benefit.
The commercial risk is straightforward: if Vietnam’s domestic crop disappoints, the country may need to rely even more heavily on imported raw cashew nuts. That could increase competition for African RCN and put pressure on Vietnamese processing margins.
West Africa: not a simple “bad crop” story
West Africa is more complex. Côte d’Ivoire, Ghana, Nigeria, Benin and Guinea-Bissau are all important to global raw cashew supply, but the ENSO signal in the region is not uniform.
El Niño can increase risk around flowering and fruit set if dry-season anomalies intensify or rainfall distribution becomes unfavorable before the crop is fully set. At the same time, drier harvest conditions can improve drying, reduce moisture problems and support outturn.
That makes West Africa the most two-sided region in this analysis.
For buyers, the practical implication is that West Africa should not be treated as automatically bullish or bearish under El Niño. The market will need to monitor local rainfall distribution, flowering conditions, quality, moisture and export timing country by country.
Côte d’Ivoire remains especially important because of its scale and because Vietnamese buyers depend heavily on African raw cashew supply. Even if West Africa produces an ordinary crop, stronger Asian demand for RCN could make African origin differentials more sensitive.
India: monsoon risk and import demand
India is another important watchpoint. IMD research describes ENSO as a major driver of year-to-year variation in Indian summer monsoon rainfall, with El Niño typically associated with a weaker monsoon.
A weaker monsoon does not guarantee a poor Indian cashew crop, but it does raise downside risk to domestic production and upside risk to import demand.
This matters commercially because India is both a producer and a major processor/importer of raw cashew nuts. If India and Vietnam both increase their need for imported RCN at the same time, the market could become more sensitive to African farmgate policies, shipment timing, quality claims and farmer selling behavior.
In that scenario, the issue may not only be total global crop size. The more important factor could be how much good-quality, exportable RCN is available at the right time.
Tanzania, Mozambique and Brazil: late-season flexibility at risk
Tanzania and Mozambique are important because they help fill the global supply calendar later in the year.
Tanzania can face risks from excessive rainfall, including cashew blight and drying delays. Mozambique sits more clearly in the Southern African El Niño drought-risk zone, with additional exposure to cyclone and logistics disruptions.
Brazil is not the central price-setting origin in cashews, but it still matters as part of global supply diversity. Northeast Brazil is the key cashew zone, and drought and heat are the main El Niño-related concerns there.
In a tighter global weather narrative, even a smaller origin can matter if buyers are looking for alternative supply.
Price risk: upside, not certainty
The strongest conclusion is not that cashew prices must rise. The better framing is that El Niño could increase upside risk, especially if several supply-side pressures occur together.
There are three market layers to watch.
First, raw supply risk could rise if Southeast Asia dries, India’s monsoon disappoints and selected African or Brazilian origins underperform.
Second, processing-margin risk could increase if Vietnam needs more imported RCN while African exportable surplus is affected by local processing, policy or farmer holding behavior.
Third, quality and contract-performance risk could become as important as tonnage. Cashew markets react quickly to moisture, outturn, nut count and shipment timing.
This means the first market reaction may not be a broad price rally. It may show up in origin differentials, quality premiums, cleaner outturns, dependable shipment timing and stronger competition for specific origins.
Non-weather variables also remain important. Demand in destination markets, freight, currencies, trade policy, local processing incentives and origin selling behavior can all influence final price formation. Weather may raise the risk premium, but it will not set the market alone.
What buyers should monitor now
The next three to six months will be important for determining whether El Niño remains a manageable weather risk or becomes a stronger market driver.
For cashew buyers and processors, the most important indicators are:
- Whether NOAA and other agencies continue to upgrade the strength outlook.
- Whether ocean-atmosphere coupling strengthens through summer.
- Indian monsoon performance.
- Lower Mekong rainfall and heat stress in Vietnam and Cambodia.
- West African rainfall distribution and flowering conditions.
- Vietnam and India’s RCN import pace.
- Origin policies and local processing moves in Côte d’Ivoire, Ghana, Benin and other African origins.
The most useful market message is measured rather than alarmist: scenario planning is warranted, but panic buying is not.
El Niño is now the base case. A truly top-tier “Super El Niño” is not. The cashew market should prepare for higher weather sensitivity, more attention to quality and moisture, and less margin for error across origins.
Conclusion
For cashew markets, the 2026–27 El Niño risk should not be ignored, but it should also not be overstated. The official forecast picture supports a high probability of El Niño development, while the strength of the event remains uncertain.
The biggest risk is not one single global crop failure. It is the possibility that several important cashew origins face weather stress at the same time: Southeast Asian dryness, weaker Indian monsoon conditions, mixed African flowering and quality risks, and drought pressure in Brazil or Southern Africa.
For buyers, the right response is to monitor origins more closely, diversify where possible, and keep quality, moisture and outturn assumptions conservative.
The market may become more weather-sensitive, but the final impact will depend on timing, regional crop development, demand, freight, policy and currency movements.
