Indonesia and the Philippines formalise a coordinated nickel corridor
25 May 20266 min read
Summary
- The Asosiasi Penambang Nikel Indonesia (APNI) and the Philippine Nickel Industry Association signed a Memorandum of Understanding on Strategic Nickel Industry Development Cooperation on 7 May 2026 in Cebu, witnessed by Indonesia's Coordinating Minister Airlangga Hartarto and Philippine Trade and Industry Secretary Maria Cristina Roque.
- The agreement commits to a minimum monthly supply of 200,000 metric tonnes of nickel beginning June 2026 and sets a structured framework connecting Philippine upstream ore with Indonesian downstream smelting capacity.
- Nickel is the metal that determines how much energy an EV battery can store; with the corridor accounting for 73.6% of global nickel production, what gets coordinated in Jakarta and Manila will be felt in every EV battery cell delivered through 2027.
Indonesia and the Philippines have formalised a coordinated nickel supply corridor that will move 200,000 metric tonnes of ore per month from Philippine mines into Indonesian smelters from June 2026, under a Memorandum of Understanding signed in Cebu on 7 May 2026. The signing was witnessed by Indonesia’s Coordinating Minister for Economic Affairs Airlangga Hartarto and Philippine Trade and Industry Secretary Maria Cristina Roque, and the document formalises a partnership between the Asosiasi Penambang Nikel Indonesia (APNI) and the Philippine Nickel Industry Association (PNIA). According to United States Geological Survey (USGS) data, the two countries together accounted for 73.6% of global nickel production in 2025.
Coordination between the two largest producers has consequences that single-country dominance does not. For EV battery makers and stainless steel buyers in particular, 7 May 2026 should be read as the date the Asia nickel market shifted from ‘Indonesia-dominant, Philippines-adjacent’ to ‘Indonesia and the Philippines, coordinated’. To understand why that shift matters, it helps to remember what nickel actually does inside an electric vehicle battery.
Why nickel is the metal that defines EV battery range
Most electric vehicles sold today run on a battery chemistry called NMC, short for Lithium Nickel Manganese Cobalt Oxide. The cathode is the part of the battery that stores energy when the vehicle is charging and releases it when the vehicle is driving, and nickel is the metal that determines how much energy the cathode can hold. The Nickel Institute reports that nickel is the primary driver of energy density inside the cathode, meaning that for a fixed-size battery pack, more nickel allows the vehicle to travel further between charges.
The industry trend is to push nickel content higher. The NMC 811 chemistry that dominated EV sales in 2022 used 80% nickel in the cathode. Tesla and other leading manufacturers are shifting to NMC 955, which raises the nickel share to 90%. Higher nickel content delivers longer driving range without a larger battery, and reduces the cobalt and manganese the cathode requires. The trade-off is process complexity and material cost, both of which depend on a stable nickel supply. Korean producers Samsung SDI, LG Energy Solution and SK On, the Chinese producers CATL and BYD, and the Japanese producer Panasonic all build their cathode strategies around assumptions about Indonesian nickel availability through 2027.
That dependency is the reason the IndoPhil corridor is a procurement question, not just a trade-policy one. Coordinated supply across 73.6% of global production means coordinated input cost for the metal that determines how far the next generation of EVs will drive.
What the MoU actually commits to
The MoU on Strategic Nickel Industry Development Cooperation sets out four working areas. First, exchange of nickel data and information across the two associations, which is the foundation for any coordinated pricing or volume behaviour. Second, policy and regulatory dialogue, intended to reduce the regulatory friction that has historically slowed Philippine ore exports into Indonesia. Third, cross-border investment promotion, opening the door to Indonesian smelter operators investing in Philippine upstream mining and the reverse. Fourth, environmental, social and governance (ESG) methodology harmonisation, which matters because EU and US buyers are increasingly attaching battery materials sourcing conditions to imports.
The 200,000 metric tonne monthly figure is the supply-side commitment that anchors the deal. ANTARA News and the Philippine News Agency report that the volume begins June 2026 and represents a structured monthly floor rather than an annual contract. Indonesia Business Post notes that the corridor is positioned to feed Indonesia’s HPAL (high-pressure acid leach) processing plants, which produce the mixed hydroxide precipitate used in lithium-ion cathode manufacturing.
Why Indonesia needs Philippine ore now
Indonesia’s 2026 mining quota allocation under the Rencana Kerja dan Anggaran Biaya (RKAB) process came in materially below 2025 production levels, with the Ministry of Energy and Mineral Resources framing the reduction as an environmental and reserve-management measure. The operational consequence for downstream operators is that Indonesian smelters had begun sourcing additional ore from external suppliers, including the Philippines, by mid-2025 to maintain processing capacity. The 7 May MoU formalises an arrangement that was already running on spot terms, based on the trade flow visible in Indonesian customs data through late 2025.
Philippine producers benefit from the formalisation because it converts ad hoc spot sales into a contracted relationship with structured volume. Cebu Daily News reported in May 2026 that Philippine nickel producers had been operating below capacity in 2024 and early 2025 due to weakened Chinese demand. The corridor reorients Philippine ore from a Chinese-buyer dependency to an Indonesian-smelter dependency, which carries different risks but at least diversifies the buyer base.
What this means for battery and stainless steel buyers
For EV battery cell makers in Korea, Japan and China, the corridor changes the procurement question. The two largest nickel-producing countries are now coordinating, which means that ore-price arbitrage between Philippine and Indonesian sources will narrow. Battery buyers should expect Indonesian mixed hydroxide precipitate prices to track the coordinated input cost rather than benefiting from inter-country price competition the way they did through 2024. Because nickel is the primary driver of cathode energy density, the cost of higher-nickel formulations like NMC 955 becomes more directly linked to the coordinated supply position than it was when Indonesia and the Philippines were trading on independent terms.
For stainless steel mills in China, Japan and Korea that source nickel pig iron and ferronickel from Indonesia, the same logic applies. Indonesian ferronickel pricing has historically reflected the country’s own ore costs. From June 2026, the input cost will reflect a Philippine ore component that is contractually structured rather than spot-priced. The likely effect is reduced volatility in Indonesian ferronickel pricing through 2026 and 2027, but a higher floor than the 2023-2024 trough.
What to watch through 2026
Three things will determine whether the corridor sets prices or merely coordinates volumes. First, whether monthly shipments from the Philippines to Indonesia hit or exceed the 200,000 metric tonne floor in the first three months. Second, whether the ESG methodology working stream produces a published standard that EU and US buyers can use for battery passport compliance. Third, whether Chinese stainless steel mills, the largest historical buyer of Philippine ore, respond by securing alternative supply from New Caledonia or Russia. The first will be visible in June and July customs data. The second will probably take 12 to 18 months. The third should be visible in Chinese ferronickel import data through the second half of 2026.
The procurement timing question is open for the buyers who will lock in 2027 battery materials volumes. Two governments, two industry associations and an MoU that did not exist six months ago now run the price-discovery process for the world’s most energy-dense cathode metal. The volumes that get committed before the second half of 2026 will set the bargaining baseline for the period after.
