Aluminium importers already operate with substantial working-capital requirements. High metal prices, regional premiums, inventory financing and extended transport schedules tie up significant capital. The Carbon Border Adjustment Mechanism (CBAM) adds another funding requirement, linked directly to the embedded emissions of imported metal.
At the Q3 2026 CBAM certificate price of €82.32/tCO2, an importer with residual exposure of 50,000 tCO2 faces an indicative certificate cost of approximately €4.1 million, before financing expenses and other applicable adjustments. For a large trading operation, this obligation can arise alongside metal inventories worth tens of millions of euros.
Carbon hedging does not remove liquidity risk
Using EUA futures to manage exposure to rising carbon prices does not eliminate the need to finance CBAM obligations. Derivative positions can generate margin calls before the importer purchases the certificates required for compliance.
A rising carbon market can therefore increase short-term cash requirements even where the hedge ultimately produces a financial gain. The timing of derivative collateral payments and CBAM certificate purchases may create a liquidity gap that is not visible in a conventional commodity procurement budget.
Banks reassess inventory and credit facilities
Lenders need to consider metal financing, projected CBAM certificate requirements, derivative collateral and customer payment terms as connected elements of the same working-capital cycle.
Existing commodity credit facilities may not provide sufficient headroom for these additional obligations. Importers and banks may therefore consider dedicated carbon sublimits within revolving credit facilities, rather than relying entirely on established metal-financing arrangements.
The treatment of CBAM costs in supplier contracts also affects the buyer’s financing requirement. A supplier offering a carbon-inclusive delivered price may fund the exposure itself and recover the expense through a higher premium. Under another commercial arrangement, the importer may be responsible for financing and purchasing the certificates directly.
Comparing these offers requires more than examining the stated carbon cost. The financing expense and timing of cash outflows must also be included in the landed-cost calculation.
New opportunities for specialised trade finance
The additional liquidity requirement creates scope for financing structures tailored to carbon-related expenses. These may include carbon-adjusted inventory finance, dedicated margin facilities for EUA hedging and sustainability-linked pricing arrangements.
Verified lower-emissions aluminium can reduce the importer’s CBAM exposure and, in turn, the amount of working capital needed to cover certificate costs. This creates a potential connection between supplier emissions performance, procurement terms and financing conditions.
For aluminium traders, CBAM is therefore more than an additional charge per tonne. It introduces a new liquidity requirement into a business where inventory turnover, financing costs and access to working capital already play a central role in commercial competitiveness.
