Barclays is warning that an El Niño commodity shock may be taking shape, with weather disruption, low inventories and supply constraints converging across global markets. The bank’s analysis points to the possibility of a historic El Niño event peaking between late 2026 and early 2027, creating outsized risks for food, energy and metals prices.
The most immediate pressure could hit agricultural commodities. Barclays estimates palm oil, coconut oil and rubber could climb 30% to 40% over the next 18 months, while robusta coffee may rise 20% to 30% and rice could gain 10% to 20% as drought conditions intensify across key producing regions.
The warning matters beyond crop markets. Barclays sees the same weather pattern spilling into industrial supply chains, with aluminum and copper potentially advancing as much as 20%, and thermal coal rising 20% to 40% if drought, mining disruption and power-market stress deepen.
Key Facts
- Barclays cited forecasts showing the El Niño index could peak near 3.2 degrees Celsius between late 2026 and early 2027.
- The projected event would be about 15% stronger than the 2015-16 Super El Niño if the forecast is realized.
- Barclays expects palm oil, coconut oil and rubber to rise 30% to 40% over the next 18 months.
- Robusta coffee could increase 20% to 30%, while rice prices may advance 10% to 20%.
- The Quantix Commodity Index Total Return has gained more than 22.5% since late June, signaling a broad-based rally across 24 commodity futures markets.
El Niño Commodity Shock
The central issue is not simply bad weather, but a tightening physical market that may have less resilience than in prior cycles. Years of underinvestment in resource production, declining inventories in several commodity chains and trade restrictions on critical materials have left the market more vulnerable to disruption. A powerful El Niño can then act as the trigger rather than the sole cause of higher prices.
In agriculture, the risk is straightforward: drought and shifting rainfall patterns can reduce yields, strain irrigation systems and cut export availability. Southeast Asia is especially important for palm oil, rice and rubber, while parts of Central America are relevant for coffee and other crops. If production losses emerge in several regions at once, buyers may be forced to compete for tighter supplies, accelerating price gains and feeding through to food inflation.
Industrial commodities are exposed through a different mechanism. Drought can reduce hydropower output, raise electricity costs for smelters and interrupt mine-to-port logistics. That matters for aluminum and copper, two metals already supported by structural demand tied to grids, electrification and data-center expansion. With copper prices already near record territory in recent trading and zinc inventories reported sharply lower this year, weather-related disruptions could amplify an already tight setup.
“The illusion of abundance is likely behind us.”
Why the Supply Risk Could Broaden
Commodity shocks rarely stay isolated. Higher agricultural prices can lift biofuel feedstock costs, affect edible oils and reshape trade flows. At the same time, reduced hydropower can force utilities toward thermal generation, increasing coal demand just as drought disrupts production and transport. That creates a feedback loop across food, fuel and industrial inputs.
Recent market moves suggest investors are already starting to price a broader scarcity theme. Wheat has pushed to a three-year high amid Black Sea disruption, copper has logged an extended run near record levels, zinc has touched a four-year high, and cocoa and tin have also posted sharp gains. The breadth of the rally is notable because it points to tightening conditions across multiple sectors rather than a single speculative burst.
Implications for Investors
For investors, the main takeaway is that weather risk is evolving into a macro risk. A stronger El Niño could push commodity inflation higher at a time when central banks remain sensitive to sticky price pressures. That has consequences for rate expectations, margins in food and industrial sectors, and the relative performance of producers versus consumers of raw materials.
Equity exposure may matter as much as futures exposure. Barclays highlighted Bunge and Archer-Daniels-Midland as potential beneficiaries in agriculture, while Norsk Hydro, South32 and Rio Tinto could benefit from stronger aluminum pricing. In copper, companies including Freeport-McMoRan, Hudbay Minerals, First Quantum Minerals and Southern Copper offer leverage to a bullish metal-price scenario. Investors should still weigh company-specific risks such as costs, jurisdiction, balance-sheet strength and hedging practices.
The risk side is equally important. Food manufacturers, airlines, chemical companies and other heavy commodity users could face input-cost pressure if the rally broadens. Investors should also monitor whether higher prices are driven by genuine physical tightness or by temporary sentiment. Key watch-points include rainfall and temperature updates, crop-condition reports, hydropower levels, exchange inventories, export restrictions and freight bottlenecks in major producing regions.
If El Niño forecasts continue to strengthen into 2027, commodity markets may shift from a cyclical rebound into a more durable scarcity trade. The next phase will depend on whether weather stress begins to show up in harvests, power generation and mine supply on a scale large enough to validate the bullish price targets.
