Palm Oil’s War Boom Is Testing Southeast Asia’s Limits

In the humid lowlands of Sumatra, harvesters move through endless rows of oil palms before sunrise, cutting heavy crimson fruit bunches with long poles while trucks idle nearby, waiting to rush the crop to processing mills before it spoils. Across Indonesia and Malaysia — producers of roughly 85% of the world’s palm oil — the industry has once again found itself pulled into the gravitational force of distant geopolitical crises.

Escalating tensions in the Middle East, including the widening regional instability involving Iran in 2026, have pushed up crude oil prices, disrupted shipping routes, and renewed demand for palm oil as a cheaper alternative for biodiesel and food manufacturing. Buyers from Asia, Europe and beyond scrambled to secure supply. Export prices climbed. Mills accelerated operations.

For a moment, the surge looked like another windfall for Southeast Asia’s most controversial commodity.

But on plantations stretching from Sumatra to Kalimantan, the boom increasingly resembles something else: a stress test for an industry running into environmental, biological and economic limits after decades of relentless expansion.

“This is not the kind of rally the industry can easily sustain,” said Sathia Varqa, a Singapore-based palm oil analyst and co-founder of Palm Oil Analytics. “Higher prices may improve revenues temporarily, but structurally the sector faces declining productivity, aging trees, labor shortages and climate-related disruptions.”

The optimism visible in export figures masks a deeper fragility within the world’s most dominant vegetable oil market.

 Smallholders Under Pressure

The strain is especially visible among smallholders, who produce around 40% of Indonesia’s palm oil and form the backbone of the industry. In rural Sumatra, small farms sit between vast corporate estates, their yields increasingly vulnerable to rising costs and erratic weather.

Many farmers initially welcomed the jump in prices. But the benefits have been uneven. Fertilizer costs — already among the largest expenses in palm cultivation — surged following global supply disruptions linked to conflict and energy market volatility.

“No one expected this war to happen,” Varqa said. “Plantations and farmers did not maintain large fertilizer inventories, so many had to ration usage almost immediately.”

The consequences unfold slowly but visibly. Farmers unable to afford standard fertilizer applications often reduce quantities or turn to cheaper substitutes such as organic manure. The trees survive, but yields weaken over time. Fruit bunches become smaller. Oil extraction rates decline.

Unlike annual crops, oil palms are highly dependent on long-term maintenance. Neglecting nutrients today can reduce output months or even years later.

“Palm oil is a biological system, not a factory,” said James Fry, chairman of commodities consultancy LMC International. “You cannot simply increase production overnight because prices rise. Trees respond slowly, and weather increasingly complicates the equation.”

Across Indonesia and Malaysia, another problem is looming: millions of hectares of aging palms are approaching the end of their most productive life cycle. Oil palms generally yield best between seven and 25 years of age. After that, harvesting becomes more difficult as trees grow taller, while fruit production gradually falls.

Replanting is expensive and risky, especially for smallholders.

Farmers must cut down old trees, prepare land, purchase seedlings and wait several years before new palms begin generating income. Although government subsidy programs exist in Indonesia and Malaysia, analysts say they often fail to fully cover the costs or compensate for lost earnings during the transition period.

“The economics discourage timely replanting,” said Abdul Rahman Ismail, a Malaysian agricultural economist specializing in plantation systems. “When prices are high, many farmers delay replacing old trees because they want to maximize short-term income, even though productivity is already declining.”

The result is a quiet erosion of future supply capacity beneath the surface of today’s export boom.

 Climate Stress and Biological Limits

Climate pressures are adding another layer of uncertainty.

Oil palms thrive under stable tropical conditions: consistent heat, abundant rainfall and predictable seasonal patterns. But Southeast Asia’s climate is becoming less reliable. Extended droughts linked to El Niño events increasingly alternate with severe flooding, disrupting pollination, fruit development and harvesting cycles.

Researchers have warned that parts of Indonesia and Malaysia may gradually become less suitable for oil palm cultivation if temperatures continue rising and rainfall patterns become more erratic.

“Extreme weather events are no longer occasional anomalies,” said Erik Meijaard, a conservation scientist and chairman of the Borneo Futures initiative. “They are becoming part of the operating environment for plantations.”

Heat stress can reduce photosynthesis and weaken fruit formation. Excessive rainfall damages transport roads and delays deliveries to mills, where timing is critical because fresh fruit deteriorates rapidly after harvesting.

Fluctuating moisture conditions also contribute to the spread of diseases such as basal stem rot, one of the most destructive threats facing oil palms in Southeast Asia.

The industry has not stopped growing entirely. Large companies continue investing in higher-yield seedlings, mechanization and sustainability certification systems. Governments in Indonesia and Malaysia still view palm oil as strategically vital for exports, rural employment and domestic biodiesel programs.

What has increasingly become a battleground over land and resources, Papua, a region with a history of unrest and insurgency, is now being treated by Indonesia as a new frontier for palm oil expansion as land shortages and environmental restrictions slow growth in Sumatra and Kalimantan. The government has linked new plantation projects in South Papua to its biodiesel strategy and energy self-sufficiency goals. But environmental groups warn the expansion risks accelerating deforestation and indigenous land conflicts, arguing Jakarta is shifting the industry’s pressures eastward rather than addressing declining productivity in existing plantations.

 The Global Ripple Effect

The effects ripple far beyond Southeast Asia.

Australia and New Zealand import significant volumes of palm oil and palm-based products for food manufacturing, cosmetics, industrial uses and livestock feed. Australia relies heavily on imported palm oil for processed foods, while New Zealand’s dairy sector uses palm kernel expeller as supplemental feed for cattle.

When prices rise or supply tightens in Indonesia and Malaysia, costs travel through global supply chains into supermarket shelves and agricultural industries thousands of kilometers away.

Manufacturers often have few easy substitutes. Palm oil remains one of the world’s most efficient vegetable oils, producing far more oil per hectare than soybean, sunflower or rapeseed crops. Replacing it entirely would require substantially more land elsewhere.

That efficiency is one reason the industry remains deeply entrenched despite years of environmental criticism.

“Palm oil is not disappearing,” Fry said. “The question is whether the industry can stabilize productivity while reducing environmental pressure and helping smallholders adapt.”

Importers, traders and manufacturers are now watching Southeast Asian weather patterns and biodiesel policies almost as closely as they monitor energy markets.

A Boom That Reveals the Industry’s Fragility

For now, the current rally — fueled by geopolitical instability and elevated energy prices — has exposed how tightly balanced the system has become.

Indonesia’s biodiesel mandates continue diverting part of domestic production away from export markets. Climate variability is increasing supply volatility. Aging trees are reducing yields. Farmers face mounting financial pressure.

Yet in plantation communities, work continues much as it always has. Harvesters move beneath towering palms in oppressive heat. Trucks haul fruit through muddy roads toward mills operating around the clock. Smallholders weigh whether they can afford another season without replanting.

The global market may still treat palm oil as an endlessly expandable commodity. On the ground, however, the industry increasingly looks like a living system approaching its limits.

And while war abroad may temporarily inflate prices, it cannot solve the deeper vulnerabilities taking root beneath the fronds.
