IDXCarbon Recap: August 2026

IDR 78136/tCO2e was the headline IDXCarbon average price in August, a much lower print than July’s IDR 74366400/tCO2e and accompanied by broader traded volume.

Price

August’s average price of IDR 78136/tCO2e reset the visible market level after July’s unusually high average price of IDR 74366400/tCO2e. The direction was clear: price discovery moved down sharply, while the market also showed more transactions by volume.

For buyers, the August print is the more relevant reference point for near-term procurement discussions than July’s thinly traded level. It suggests that executable pricing can look very different when more volume is present. Buyers should still treat the average price as a market signal rather than a guaranteed procurement level, because IDXCarbon remains sensitive to the project type, vintage, and available supply behind each trade.

For sellers, the month reinforces the need to distinguish between posted expectations and tradeable demand. A high single-month price can attract attention, but August’s lower average price points to where bids may have become more realistic when market participation widened. Sellers preparing offers should benchmark against live market evidence on KarbonLens prices, not only against the prior month’s headline.

Liquidity (volume & value)

Liquidity improved in volume terms. August traded volume was 227 tCO2e, compared with July’s 1 tCO2e. That is a meaningful change in market depth, even though the absolute level remains modest for corporate buyers that need larger retirement or inventory programs.

Traded value moved in the other direction. August traded value was IDR 17737000, while July traded value was IDR 74366400. The combination of higher volume and lower value confirms that the price reset dominated the month’s turnover profile. In practice, this means the market became more active in units traded, but not in rupiah turnover.

Participants should read the liquidity picture carefully. A larger volume base gives buyers and sellers a better signal than a near-empty month, but IDXCarbon still needs repeated monthly depth before the average price can be treated as a robust benchmark. The August data is useful, but it is not yet a full liquidity curve.

What it means for participants

Buyers: August offers a more usable reference point for budget setting and internal carbon cost assumptions. Procurement teams should compare IDXCarbon prints with project-level availability, eligibility, and retirement requirements before committing. A lower average price can help revive buyer interest, but execution still depends on available supply and registry readiness.

Sellers: The month shows that liquidity can appear when pricing meets demand. Sellers may need to prepare differentiated offers by project quality, co-benefits, and documentation rather than relying only on scarcity narratives. If the market continues to clear closer to August levels, disciplined offer strategy will matter more than headline asking prices.

Policymakers: August underlines the importance of transparent and continuous market data. Higher traded volume is positive for price discovery, but lower traded value also shows how fragile the benchmark can be. Policy support that increases eligible supply, clarifies compliance demand, and improves disclosure would help convert episodic trades into a more reliable market.

Coverage context

KarbonLens currently tracks 69 Indonesian carbon projects and 25668148 tCO2e of issued credits across those tracked projects. That coverage matters because IDXCarbon pricing is only one part of the domestic market picture: participants also need to understand project pipelines, issuance profiles, and supply quality.
