Indonesia's mining revenue passed its audit, and the fiscal value of the sector is now measured to that standard

An audit opinion, and what it certifies

On Wednesday, 5 August 2026, the Audit Board of the Republic of Indonesia handed the Ministry of Energy and Mineral Resources the result of its examination of the ministry's financial statements for the 2025 fiscal year. The opinion was Wajar Tanpa Pengecualian, the unqualified opinion the Board issues when a set of accounts presents its information fairly in all material respects, discloses adequately, complies with the applicable regulations, and rests on internal controls that function.

Minister of Energy and Mineral Resources Bahlil Lahadalia described the outcome in Jakarta the following morning as evidence of continuity in how the ministry manages and accounts for public money. He paired the point with a condition on how the revenue should keep growing.

"Revenue increases must continue to be carried out accountably and transparently, and with attention to the sustainability of natural resource management," Bahlil said, after describing the audit result as a sign of the ministry's consistency in the quality of its financial management and accountability.

Nyoman Adhi Suryadnyana, Member I of the Audit Board, made a narrower observation that is worth pausing on. Few ministries, he noted, record their success principally through the performance of their core business. Most audit opinions certify that a ministry spent an allocated budget properly. This one certifies something different in kind. It certifies that a ministry measured, collected and accounted for the money that Indonesia's resource base generated, at a scale that dominates the ministry's own financial statements.

For institutions working on resource governance, that distinction is the story. The fiscal value of Indonesian mining is no longer an estimate produced by the sector for the sector. It is a figure that has been through an external examination and survived it.

The composition of the number

Non-tax state revenue managed by the ministry reached Rp138.40 trillion in 2025 against a target of Rp127.48 trillion, an achievement of 108.56 percent. The mineral and coal subsector supplied Rp130.17 trillion of that, or 104.38 percent of its own target of Rp124.71 trillion. Mining is not one contributor among many in this ledger. It is the ledger.

The internal composition is where the more useful reading sits. Royalties delivered Rp106.26 trillion against a target of Rp83.52 trillion, an achievement of 127.23 percent. The net profit share from special mining business permits, the IUPK instrument, brought Rp4.26 trillion against Rp3.50 trillion, or 121.78 percent. Landrent, the fixed area fee, returned Rp0.67 trillion against Rp0.46 trillion, or 143.77 percent. The one component that fell short was the sale of mining output, which delivered Rp18.98 trillion against a target of Rp37.23 trillion, or 50.99 percent.

Three of the four components overshot, and the one that missed is the component tied most directly to physical tonnage moved and sold by the state's own account. The components that overshot are the ones indexed to price and to profitability. According to the ministry, royalties have been the largest contributor to mineral and coal revenue for five consecutive years, and the strength of gold prices since 2024, together with regulatory changes to metal mineral royalty rates, lifted the 2025 figure well past its target.

That is the structural point. Indonesia's fiscal return from mining now tracks the value of what is extracted rather than the volume of it. A tonne of ore that leaves the country as a higher grade product, at a higher price, in a year of firm metal markets, pays more than a tonne that leaves as raw material in a soft market. The revenue system has been rebuilt to notice the difference.

The trajectory through the year also deserves a note, because it shows how carefully the figure was tracked. As of 15 November 2025, realisation stood at Rp114 trillion, or roughly 92 percent of target. In late December, Director General of Minerals and Coal Tri Winarno projected that the year would close between 105 and 110 percent of target. The final audited figure of 104.38 percent landed just under that projection. Forecasting to within a few percentage points on a base above Rp120 trillion is a governance result in itself.

For 2026, collection through the end of July stood at Rp96.26 trillion against a target of Rp136.18 trillion, or 70.69 percent. Two thirds of the year's target was in hand with five months of the year remaining.

What made the number auditable

An audit opinion of this kind is not produced by good intentions. It rests on infrastructure, and in this case the infrastructure has a name. SIMBARA, the mineral and coal information system operated jointly across ministries and agencies, has been running since 2022. Coal was integrated in 2023, and nickel and tin followed in 2024.

SIMBARA is built around traceability across five flows: documents, goods, money, transport, and the entities involved. It links a single taxpayer identity to the permit, the sales plan, the sales verification, the revenue payment, the export, the shipment, and the foreign exchange proceeds. An Automatic Blocking System prevents a shipment from proceeding where an obligation is outstanding. The effect is that a cargo cannot become revenue without leaving a record, and a record cannot exist without a matching payment.

This is what turns a resource endowment into an auditable number. The ministry supported the 2025 result with cross ministry data integration through SIMBARA, the blocking system, the use of a single taxpayer identity, formal inter agency cooperation, and sanctions for non compliance. Each element narrows the space between what was mined and what was declared.

The half of the ledger still being built

The fiscal value of mining is now measured to audit standard. The environmental value associated with the same activity is measured to a different and less settled standard, and that gap is where the next phase of work sits.

The instruments already exist. Reclamation and post mining guarantees placed by companies had reached around Rp35 trillion by late 2025, with 1,592 further applications awaiting approval. That is a substantial pool of money whose adequacy depends entirely on how accurately the cost of restoring a given piece of land has been calculated. Permen LH No. 7 Tahun 2014 provides Indonesia's regulatory methodology for pricing ecological damage, environmental economic loss, and recovery cost. Every AMDAL document contains a projection of impact that could, in principle, be tested against outcomes.

What is less consistent is the evidence base underneath these instruments. A reclamation guarantee calculated from a standard cost table describes an average hectare. A guarantee calculated from satellite imagery of the actual disturbed area, ground verified soil and water measurements, and a species inventory describes the specific site. The two figures can differ materially, in either direction. Operators who have restored more than their permit required have as much interest in the second method as regulators do, because only the second method can demonstrate it.

Sirkularium's view

The audit result is a good outcome and should be read as one. Indonesia has built, over roughly four years, a system that converts mining activity into a revenue figure precise enough to withstand external examination. That is a genuine institutional achievement, and the ministries and agencies that built SIMBARA and the accountability framework around it deserve the credit.

Sirkularium's read for government and for operators is that the same discipline can now be extended to the environmental side of the same activity. The fiscal ledger works because every tonne is traced through documents, money and entities, with a single identity linking them. The environmental ledger can be built on the same principle: GIS and remote sensing to establish what changed on the ground and when, field measurement of water quality, soil condition, biodiversity and carbon to calibrate the imagery, and the existing Permen LH No. 7 Tahun 2014 methodology to convert those measurements into monetary terms.

Two things are worth watching over the remainder of 2026. The first is whether the 2026 revenue figure closes above target for a second consecutive year, which would confirm that the value based royalty structure is stable rather than a product of one strong price cycle. The second is whether the 1,592 pending reclamation guarantee applications are assessed against site specific evidence or against standard tables.

For mining operators, the practical conclusion is straightforward. The fiscal value of their activity is now documented to a standard that regulators trust. Commissioning independently verified economic valuation of the environmental dimension, built on GIS plus ground data and standard methodology, and maintained as ongoing practice rather than assembled in response to a dispute, brings the second half of the ledger to the same standard. A company that can present both halves is in a materially stronger position with the Ministry of Environment and Forestry than one that can present only the first.
