Nickel Indonesia Quota Cut: RKAB Slashed 30-34% as Eramet Halts Production at Weda Bay

The Indonesian government has implemented its most aggressive nickel supply intervention to date, slashing the 2026 RKAB (Rencana Kerja dan Anggaran Biaya) quota by roughly 30-34% to between 250 million and 270 million wet metric tonnes, down from 379 million wmt previously allocated. The policy is explicitly designed to arrest the multi-year decline in nickel prices and support Indonesia's vast downstream processing industry.

The market response was immediate and unambiguous. Shanghai Futures Exchange (SHFE) nickel surged more than 4% within hours of the announcement, and LME three-month nickel rose to approximately $19,410 per tonne by May 4, 2026 — representing a 13.9% monthly gain and a 24.9% year-on-year increase. (FACT: Trading Economics, May 4, 2026; IDNFinancials, April 28, 2026) The rally was concentrated in the refined metal complex, with NPI and ferronickel premiums also reacting as smelters began pricing in ore scarcity.

The quota reduction creates a structural ore deficit of approximately 80-100 million wmt relative to installed smelter capacity. According to industry estimates, this gap reduces smelter utilization rates from roughly 90% to 70-75% in 2026, forcing operators to compete aggressively for available ore, bid up domestic ore premiums, and in some cases suspend operations entirely.

The most visible casualty is Eramet's PT Weda Bay Nickel operation. Following the RKAB cuts, Eramet announced it would temporarily halt production beginning May 2026 after exhausting its 2026 RKAB allocation. The French mining group also confirmed it is preparing a €500 million capital increase in the second half of 2026, with board approval already secured. Reports from MySteel and IDNFinancials indicate that Indonesia's sovereign wealth fund Danantara is exploring the acquisition of Eramet's 38.7% stake in PT Weda Bay Nickel, a move that would further consolidate Indonesian state control over the country's nickel supply chain.

The policy signals a fundamental shift in Indonesia's nickel strategy. For years, the government prioritized volume growth — encouraging rapid smelter construction and ore extraction to capture downstream processing value. The 2020 ore export ban was the first major lever. The RKAB quota cut represents a second, more surgical intervention: restricting upstream supply to support prices while maintaining the downstream export infrastructure. Indonesia controls roughly 60%+ of global nickel supply, meaning its production decisions have outsized market impact. (FACT: S&P Global, December 29, 2025; Carbon Credits, 2026)

The price implications are significant. With Indonesia effectively setting a floor under prices through administrative supply restriction, analysts have revised their LME nickel targets upward to the $19,000-20,000/t range. This compares to ING's baseline outlook of $15,000-17,000/t average for 2026, suggesting that the quota cut has introduced a policy premium of roughly $2,000-5,000/t into the market. (FACT: ING Think, 2026; S&P Global, December 29, 2025)

However, risks remain. The approximately 250,000 tonnes of Class 1 nickel sitting in LME warehouses acts as a ceiling on price rallies — every significant upward move meets physical selling from inventory holders. The surplus in refined metal means that the price impact of the RKAB cut is most acute in the ore and NPI markets, while the LME-traded cathode market remains comparatively well-supplied. (FACT: LME, 2026; ING Think, 2026)

Additionally, the quota cut creates an incentive for Indonesian smelters to import ore — primarily from the Philippines — to bridge the domestic ore gap. Ore imports from the Philippines to Indonesia have been rising steadily, and the two countries signed a Memorandum of Understanding in early May 2026 formalizing what is being called the "Indonesia-Philippines Nickel Corridor." This paradox — the world's largest nickel producer importing ore from the second-largest — underscores the structural tension in Indonesia's policy framework. (FACT: SteelNews.biz, May 11, 2026; Discovery Alert, May 6, 2026)

For buyers, the key takeaway is that Indonesia has decisively shifted from a volume-maximization strategy to a price-support strategy. The 30-34% RKAB cut is not a temporary adjustment; it represents a structural policy reset. Ore-constrained smelters will face margin pressure, while producers with captive mining quotas will benefit from ore scarcity premiums. The LME price will increasingly reflect a tug-of-war between the Indonesian policy floor at $19,000-20,000/t and the inventory ceiling imposed by 250,000 tonnes of exchange stocks.
