Indonesia's Nickel Refining Monopoly and Regional Concentration Risk in EV Battery Supply Chains

Indonesia controls over 60% of global nickel refining capacity, prompting battery manufacturers to accelerate investments in alternative supply sources—Australia and the Philippines—a shift that will redefine battery pack costs and supply chain diversification.

Indonesia’s Nickel Refining Monopoly Is Reshaping the Global Battery Supply Chain

Battery manufacturers are pouring billions of dollars into nickel mines in Australia and the Philippines to break free from dependence on a single supplier. With Indonesia controlling over 60% of global nickel refining capacity, geopolitical risk and cost competition are accelerating this trend. Battery pack cost structures and supply security are being redefined simultaneously.

Indonesia’s Dominance in Nickel Refining and the Shift in the Battery Industry

Nickel is a critical raw material for lithium-ion batteries. Indonesia ranks first in global nickel ore production and holds an overwhelming advantage in the refining stage. More than 60% of global refining capacity is concentrated in Indonesian plants. This concentration in the supply chain is vulnerable to geopolitical shocks and makes it difficult for battery manufacturers to manage costs when nickel prices fluctuate.

Why Supply Chain Diversification Is Accelerating Now: Four Factors

1. Geopolitical Risk Becoming Concrete: Export restrictions by the Indonesian government, changes in environmental policy, and political instability are forcing battery companies to develop alternative supply sources. Reducing dependence on a single country has become an essential element of supply chain resilience.

2. Intensifying Mining Development Competition between Australia and the Philippines: As Australia’s abundant nickel resources and the Philippines’ development potential gain attention, strategic cooperation between mining companies and battery manufacturers is expanding. Building refining infrastructure in these countries has emerged as a medium-term priority.

3. Explosive Growth in Battery Demand: As electric vehicle sales continue to grow, nickel demand is rising alongside. Indonesia alone cannot meet growing demand, making multiple supply sources an essential strategy.

4. Battery Pack Cost Pressure and Profitability Defense: As battery prices continue to fall, manufacturers must manage raw material procurement costs more precisely. Supply source diversification is not merely risk avoidance but a cost optimization strategy.

Structural Impact on Mining Companies

A Double-Edged Sword of New Opportunities and Intensifying Competition: RIO (closing at $81.89 as of October 30, 2026) benefits from this trend as it holds strong nickel assets in Australia. However, its stock has declined 12.73% over three months, reflecting macroeconomic factors beyond mining. SCCO maintains current price strength with a high net profit margin (37.2%) and 39.1% sales growth, but companies with high dependence on Indonesian refining may face margin pressure over the long term.

Structural Weakness: Companies with existing refining capacity in Indonesia will be forced to make new investments and upgrade technology to improve unit profitability in the future. Conversely, companies building new refining capacity in Australia and the Philippines face high initial capital costs but can gain an advantage in long-term supply stability.

In Summary

Indonesia’s excessive concentration in nickel refining is triggering a redesign of battery industry supply chains. The move toward diversification into Australia and the Philippines is likely to significantly reshape the global refining landscape within five years. The choice for mining companies is clear: either secure opportunities in new regions or boost productivity in existing locations.
