ECB Expands Climate Risk Factors in Collateral Framework to Corporate Loans

The European Central Bank (ECB) has announced plans to expand its use of climate risk factors in the collateral framework to include eligible loans to non-financial corporations. This move is part of the ECB's efforts to adjust the value assigned to assets pledged by banks as collateral for central bank loans, based on their exposure to climate transition risks.

The new category, credit claims whose debtor is a non-financial corporation, forms a significantly larger portion of the Eurosystem portfolio. The ECB initially applied the climate factor only to corporate bonds pledged as collateral, but this expansion aims to address the potential impact of climate change on the value of financial assets.

The climate factor will be based on an asset-level uncertainty score comprised of three key elements: sector-level stressor derived from the latest Eurosystem climate stress test, debtor's exposure to transition-related uncertainties, and residual maturity of the credit claim. The ECB expects to implement the extension by the end of 2027 at the earliest, with climate factor values to be updated annually.
