El Niño can disrupt global supply chains by changing weather patterns, affecting agricultural production, transport routes, energy supplies and commodity prices. For procurement professionals, this can mean higher costs, longer lead times and increased supplier risk.
You may have seen El Niño mentioned in relation to periods of extreme heat, drought or heavy rainfall. But its effects can extend far beyond the weather. It is a naturally occurring climate pattern associated with unusual warming of surface waters in the central and eastern tropical Pacific Ocean. Although it originates in the Pacific, changes in weather patterns can have consequences for economies and supply chains around the world.
For procurement and supply chain professionals, El Niño is an external risk that cannot be prevented – but its potential impact can be anticipated and managed.
How can El Niño disrupt agricultural supply chains?
Agriculture is particularly exposed to changes in temperature and rainfall.
El Niño can bring drought and extreme heat to some regions while contributing to unusually heavy rainfall in others. This can affect the production of commodities such as coffee, cocoa, rice, wheat, sugar, palm oil and fruit.
The consequences for procurement teams can include:
- Reduced availability of raw materials
- Greater commodity price volatility
- Inconsistent product quality
- Longer lead times
- Increased competition for available supplies
This remains a relevant risk. In June 2026, the World Bank highlighted the potential for a stronger or more prolonged El Niño to affect several major agricultural regions simultaneously, with possible consequences for global food prices.
Procurement teams sourcing agricultural commodities should therefore monitor weather forecasts, crop reports, commodity markets and supplier locations to identify emerging risks before they affect supply.
How does El Niño affect transportation and logistics?
Extreme weather can disrupt the infrastructure that global supply chains depend on, including ports, roads, rail networks and shipping routes.
Flooding and storms can prevent goods from reaching ports, damage infrastructure and delay vessels. Drought creates a different challenge, particularly for waterways and canals that depend on sufficient water levels.
The Panama Canal provides a useful example. Drought associated with El Niño has previously contributed to reduced water levels and restrictions on vessel traffic, demonstrating how a weather event in one location can have wider consequences for international trade.
For procurement teams, disruption can lead to alternative shipping routes, longer lead times and increased transport costs.
Organisations should understand whether critical goods depend heavily on a particular port, transport route or geographical region and identify alternatives before disruption occurs.
What impact can El Niño have on energy and manufacturing?
Higher temperatures can increase electricity demand as homes and businesses use more cooling. At the same time, drought can reduce hydroelectric power generation in countries that depend heavily on reservoirs and rivers. The World Bank has identified reduced hydroelectric generation as one of the potential consequences of prolonged drought.
For procurement teams, energy disruption can create risks further down the supply chain.
Suppliers facing higher energy prices may increase their own prices or seek to renegotiate contracts. In more severe cases, unreliable energy supplies could affect manufacturing output and lead times.
Understanding a supplier’s exposure to energy and climate-related risks can therefore form an important part of supplier risk management.
How can procurement teams prepare for El Niño?
Procurement teams cannot control El Niño, but they can reduce their organisation’s exposure to the disruption it may cause.
Building greater supply chain resilience could include:
- Mapping supply chains beyond tier-one suppliers
- Identifying critical materials sourced from climate-sensitive regions
- Developing alternative suppliers and transport routes
- Reviewing safety stock levels for critical goods
- Reviewing insurance and business continuity arrangements
- Ensuring contracts clearly address weather-related risks
- Monitoring supplier financial health and operational capacity
- Collaborating with key suppliers on contingency plans
Supplier diversification can be particularly important. Heavy dependence on one supplier, country or region can leave an organisation exposed when extreme weather affects that location.
However, diversification should not be considered in isolation. Procurement teams still need to balance resilience against cost, quality, sustainability and supplier performance.
Why is El Niño a strategic procurement issue?
El Niño demonstrates why effective procurement is about more than securing the lowest price.
A low-cost supplier may offer poor overall value if its operations are highly exposed to drought, flooding, infrastructure disruption or other climate-related risks.
By combining supply chain mapping, supplier relationship management, climate intelligence and contingency planning, procurement professionals can identify vulnerabilities earlier and respond more effectively when disruption occurs.
El Niño itself may be unavoidable. Its impact on supply continuity, costs and customers, however, can be reduced through proactive procurement and supply chain risk management.
