IDXCarbon Monthly Market Report: 2026-05

IDXCarbon’s 2026-05 headline average price was IDR 60906/tCO2e. The month closed with a softer price signal than 2026-04, while trading activity also narrowed: reported volume was 219 tCO2e and traded value was IDR 13338600.

Price

The average price moved lower from IDR 76862/tCO2e in 2026-04 to IDR 60906/tCO2e in 2026-05. That shift points to a weaker clearing environment on IDXCarbon during the month, rather than a tightening one.

For buyers, the lower average price improves near-term entry conditions, particularly for entities that are building compliance readiness or testing procurement workflows. For sellers, the price move signals that bids may have become more selective, and that project-level differentiation matters when buyers can wait for attractive offers.

Liquidity (volume & value)

Liquidity also eased. Traded volume declined from 554 tCO2e in 2026-04 to 219 tCO2e in 2026-05. Traded value likewise fell from IDR 42581600 in 2026-04 to IDR 13338600 in 2026-05.

The combined pattern matters: a lower average price was accompanied by a smaller quantity traded and a smaller rupiah value transacted. That is not simply a cheaper month with heavier turnover; it was a quieter month overall. In practical terms, participants should treat the May data as a softer market print with limited depth, not as a broad repricing confirmed by high activity.

Low turnover can make monthly average prices more sensitive to the specific credits that clear. Project type, vintage preference, buyer eligibility needs, and whether a trade is opportunistic or programmatic can all shape the observed result. This makes order placement, documentation readiness, and counterparty engagement important for participants seeking reliable execution.

What it means for participants

Buyers. The lower average price may support staged procurement, especially for buyers that are not under immediate delivery pressure. However, lower liquidity means buyers should avoid assuming that all desired volumes can be sourced at the monthly average. A disciplined approach would compare available credits, eligibility, and settlement timing before committing.

Sellers. The softer price and thinner turnover suggest that sellers may need to be more deliberate about when and how they bring supply to market. Clear project documentation, transparent credit attributes, and realistic offer levels can help improve buyer confidence. Sellers with flexibility may choose to monitor bid formation before listing larger blocks.

Policymakers. The month reinforces the importance of steady market infrastructure and clear demand signals. A market with visible price discovery but modest activity can still be useful, yet deeper liquidity would make the reference price more robust. Policy clarity, onboarding support, and confidence in credit quality remain central to broader participation.
