Jakarta has this year cut mining quotas, stepped up environmental controls and adjusted ore pricing to rein in its runaway nickel sector.
A commitment to slash mining quotas from last year's 379 million metric tons to 250 million to 260 million tons propelled the London Metal Exchange nickel price CMNI3 to a May high of $20,000 per ton.
The price is now back down at $16,500 as the market loses confidence that Jakarta can tame its nickel tiger.
Policymakers' dilemma has been how to reduce mined output without disadvantaging their nickel processors, some of whom have only begun ramping up production this year.
A mid-year review of the quota system has resulted in higher allocations to specific operators.
French group Eramet ERMT.PA, for example, is restarting operations at its Weda Bay mine after being forced to suspend work in May when it had exhausted its 2026 quota.
The full extent of the upward creep is difficult to ascertain since neither Jakarta nor its nickel operators disclose details.
Moreover, it's clear some operators have adjusted to lower domestic mining rates by turning to imports, primarily from the Philippines.
Indonesia lifted imports of Philippine ore by 50% to 15.3 million tons last year and arrivals were up by another 67% year-on-year at 11.4 million tons from January to July, according to the World Bureau of Metal Statistics (WBMS), which collects data from official sources.
Another smaller stream of imports is now also arriving regularly from the Solomon Islands.
It's worth remembering that if all the country's nickel processing plants were operating at capacity, they would need 315 million tons of ore per year, according to the Indonesian Nickel Miners Association.
Balancing that captive demand with mining rates is still very much a work in progress.
