Indonesia’s downstreaming story is no longer only about nickel. In 2026, official investment figures show a sharper diversification into other minerals, especially bauxite and copper, as the government maintains its strategy of pushing domestic processing. In Q2 2026, total downstreaming investment reached Rp152.7 trillion, up 5.7% year on year, and represented 29.8% of Indonesia’s total realized investment of Rp511.8 trillion. This change matters for investors watching how new value chains are prioritized and where project pipelines are forming beyond the mature nickel ecosystem.
Bauxite is the clearest signal of that shift. Realized investment in bauxite downstreaming hit Rp40.1 trillion (about US$2.23–2.26 billion) in Q2 2026, up 193% from Rp13.7 trillion (about US$765–773 million) in the previous quarter. Investment Minister Rosan Roeslani said bauxite took first place for the first time, surpassing nickel, because several bauxite processing projects are being developed by both domestic and foreign investors. In the same quarter, nickel downstream investment stood at Rp29.4 trillion, while copper recorded Rp16.7 trillion, with iron and steel at Rp13.2 trillion and silica sand at Rp4 trillion.
Policy Signals: Export Restrictions and Broader Downstream Targets
Indonesia’s policy stance helps explain why capital is moving. Energy and Mineral Resources Minister Bahlil Lahadalia said the government would maintain its ban on exports of unprocessed mining commodities, including bauxite and copper, continuing a policy that began with nickel in 2019. The government frames export restrictions as an instrument to accelerate downstreaming, increase the value of natural resources, create jobs, and support economic growth. This approach also aligns with a broader downstream push: across 15 priority downstream commodities under the 2025–2029 RPJMN, investment realization reached IDR 273.47 trillion in the first half of 2026, equal to 27.06% of total national investment realization.
For the Indonesia copper downstream investment topic, the numbers show that copper is already a meaningful part of the mix, even as bauxite captures headlines. In H1 2026, downstream investment in Indonesia’s mineral sector reached Rp206.5 trillion, with nickel at Rp71 trillion, bauxite at Rp53.8 trillion, and copper at Rp37.4 trillion, followed by iron and steel at Rp30.2 trillion and silica sand at Rp5.9 trillion. These H1 totals suggest copper is not a niche category, but part of the core downstreaming portfolio that investors track alongside bauxite-to-alumina buildouts.
Execution on the ground is also visible in projects and employment. BKPM reported that downstream projects created 742,263 jobs during Q2 2026, up 5.1% from the previous year, while total realized investment during the first half of 2026 generated 1,448,862 jobs, around 15% higher than the same period in 2025. In bauxite, one named project is Phase I of the Smelter Grade Alumina Refinery (SGAR) in Mempawah, West Kalimantan, which has an annual production capacity of 1 million tonnes of alumina per annum. Together, these figures show a downstreaming strategy expanding beyond nickel through policy continuity, rising realized investment, and industrial projects that add processing depth.
