Nickel prices rose for a fourth straight day Wednesday after Indonesia ordered the world’s largest nickel mine to sharply cut output in a move aimed at tightening global supply and lifting prices.

LME nickel climbed 2% to $17,835 a tonne as of 6:45 a.m. London time, after earlier touching $17,910, extending a rally of more than 20% since mid-December amid speculative buying and heightened geopolitical tensions.

Indonesia plans to issue production quotas of 260 million to 270 million tonnes of nickel ore this year, according to Bloomberg, slightly above an earlier estimate of 250 million to 260 million tonnes but far below the 379 million tonnes targeted for 2025. Authorities manage output through annual mining permits, known as RKABs, and can revise volumes mid-year.

PT Weda Bay Nickel will receive a 12 million tonne ore quota this year, down from 42 million tonnes in 2025. The mine, located on Halmahera in North Maluku, is owned by Tsingshan Holding Group Co, France’s Eramet SA and PT Aneka Tambang. Eramet confirmed the reduced quota and said it plans to seek a revision, while the county’s Energy and Mineral Resources Ministry said quotas remain under evaluation.

Price control

Indonesia is trying to rein in a persistent global surplus after its production surged to about 65% of world supply, triggering a two-year price slump that forced higher-cost rivals in Australia and New Caledonia to shut down.

The quota cut will weigh heavily on Weda Bay, which had planned to expand output to more than 60 million tonnes of ore to support a nearby industrial park. Instead, it has imported large volumes of ore from the Philippines to offset local shortages.

Nickel, used in stainless steel and electric-vehicle batteries, has seen weaker-than-expected demand from the battery sector as some manufacturers shift to non-nickel chemistries.

In January, Macquarie Group raised its 2026 nickel price forecast by 18% to $17,750 a tonne on the LME, citing a sharp drop in the expected surplus due to tighter Indonesian quotas.

Curbing coal

Indonesia is also curbing thermal coal output, with mining quotas in the world’s largest exporter set to fall by nearly 25% from a year earlier. The Indonesian Coal Mining Association said the cuts could force some operations to close and leave overseas buyers scrambling for alternative supplies.
