Understanding and managing the carbon-price risk within CBAM costs

The Carbon Border Adjustment Mechanism (CBAM) has moved beyond its transitional reporting phase and into its definitive regime. For affected businesses importing certain carbon-intensive goods into the EU, it creates a carbon-linked financial exposure that can affect costs, budgets and margins.

CBAM links part of the cost of importing certain goods into the EU to the European carbon price. The price of CBAM certificates is calculated by reference to prices in the EU carbon market, known as the EU Emissions Trading System (EU ETS). In practical terms, changes in the EU carbon price can change the expected cost of meeting a CBAM obligation.

For importers, treasury teams and risk managers, this creates a new source of market risk. Quantifying the exposure and considering an appropriate hedge can help improve cost visibility, support budget certainty, and reduce the impact of adverse carbon-price movements.

Why CBAM matters

CBAM is designed to ensure that a carbon price is applied to the embedded emissions in certain goods imported into the EU. For affected businesses, carbon pricing therefore becomes part of the cost of importing those goods.

The exposure does not sit solely with sustainability, legal or compliance teams. It is also relevant to procurement, finance, treasury, and risk-management teams responsible for forecasting costs, managing margins, and assessing commercial risk.

What creates the exposure?

A business can face exposure when it imports in-scope goods in selected sectors – including cement, iron and steel, aluminium, fertilisers, electricity and hydrogen – and the embedded emissions in those goods create a certificate obligation.

Because CBAM certificate prices are calculated by reference to EU ETS allowance auction prices, changes in the EU carbon market can affect expected CBAM costs. The exposure may be particularly relevant for businesses with recurring imports, material volumes, or long procurement and pricing cycles.

How carbon price movements can affect CBAM costs

A change in the EU carbon price changes the expected CBAM cost for an importer. This is a simplified, hypothetical example for illustrative purposes only.

How Marex Hedging Solutions Can Help

Marex can help businesses assess how movements in the EU carbon price could affect their expected CBAM costs and explore tailored bilateral over-the-counter (OTC) hedges aligned with the size, timing and relevant pricing period of the exposure.

These structures can be designed to help manage carbon-price volatility, improve cost visibility and reduce the impact of adverse price movements on budgets and margins.

Hedging does not replace CBAM compliance. Accurate import and emissions data remain essential, and a hedge may not eliminate differences between forecast and actual volumes, timing, embedded emissions or certificate costs.
