Super El Niño: Palm Oil, Rubber, Sugar at Risk

A rare super El Niño is forming in the Pacific. The Australian Bureau of Meteorology raised its alert level to "watch" last week. The U.S. Climate Prediction Center gives a 70% chance of a strong event by September. Commodity traders are already repositioning.

The last super El Niño, in 2015–16, cut palm oil output in Indonesia and Malaysia by roughly 10%, according to trade data. CPO futures rallied over 30% that season. Sugar followed a similar path – Thailand and India, two of the top three exporters, both saw yields drop. Cocoa and coffee faced drier conditions in West Africa and Vietnam. The pattern repeats because the trade winds weaken, warm water shifts east, and the weather footprints shift with it.

Global vegetable oil inventories are already tight after two years of below-trend production. A supply shock would hit a market with less buffer. Crude palm oil is the first read-through. The Bursa Malaysia CPO contract has already edged up 8% in the past month as the alert level rose. Plantation stocks – Sime Darby, IOI Corp, Kuala Lumpur Kepong – are up 6–12% over the same stretch. Traders say the rally has room if the monsoon trough stays weak through July. Indonesia's export levy policy adds another variable: if prices spike, Jakarta may adjust the levy rate to keep domestic cooking oil affordable, which would cap gains. Any levy cut would widen the discount for international buyers and lift volume, benefiting refiners while compressing margins for crude sellers.

Rubber is the second exposure. Thailand and Indonesia together account for roughly 60% of global natural rubber output. A super El Niño typically brings drier weather to the main tapping zones during the peak latex flow season from June to October. The last event in 2015–16 saw rubber output fall 8% and prices climb 25%. Traders say the current market is already factoring in a 5–7% production loss. The real risk is if the dry spell extends into November, which would delay the refoliation cycle and cut the next year's harvest. Listed rubber producers like Sri Trang Agro-Industry and Thai Hua Rubber are sensitive to that timeline.

Sugar and coffee are the third pocket. India's monsoon is the key swing factor. A weak Indian monsoon during an El Niño year means lower cane yields in Maharashtra and Karnataka, which reduces sugar output and pushes domestic prices higher. The Indian government typically restricts exports when that happens, which tightens global supply. Raw sugar futures in New York have already climbed 12% this year on weather risk premiums. Coffee – especially robusta from Vietnam – faces a similar dynamic. Vietnam's central highlands get drier during strong El Niño events, and the country's robusta stockpiles are already low after two years of below-average harvests. Traders say that if the weather forecast holds, the robusta premium over Arabica could widen further.

Energy traders are watching a different angle. Atlantic hurricane season is expected to be above average this year, partly because the warm water in the eastern Pacific shifts wind patterns. That raises the risk of production shutdowns in the Gulf of Mexico, which would tighten crude and natural gas supply. The 2015–16 super El Niño coincided with a relatively quiet hurricane season. Forecasters at the National Oceanic and Atmospheric Administration say the atmospheric setup this time is different because of the Atlantic's own warming trend. Natural gas storage levels are above the five-year average now, which limits the upside unless a storm hits the LNG export terminals on the Texas–Louisiana coast.

The next concrete marker is the June–July monsoon rainfall data from the India Meteorological Department. If the cumulative rainfall deficit widens past 10% by mid-July, sugar export restrictions and palm oil import tariff changes become likelier. Traders also flag the July 10 planting progress report from Indonesia's palm oil association for the first hard acreage data. A smaller-than-expected planting rebound would reinforce the supply tightness thesis.

Demand response is the unknown. A super El Niño that drives palm oil above 4,500 ringgit a tonne risks curbing buying from India and China, the two largest importers. That would cap the rally. Commodity traders say the demand elasticity at those levels is not priced in yet, which means the commodity stocks could face a reversal if the weather forecasts prove too dire.
