ECB Expands Climate Risk Factor Application to Corporate Loans

The European Central Bank (ECB) is expanding its use of climate risk factors in the collateral framework to include corporate loans, a move aimed at strengthening the Eurosystem's risk management framework. This decision follows the recent rollout of the climate factor for corporate bonds, which were initially used as collateral.

According to the ECB, the value of financial assets can be directly affected by climate change-related uncertainties, and an unexpected drop in value caused by a climate shock could result in financial losses for the Eurosystem. The ECB plans to implement this extension by the end of 2027 at the earliest, with climate factor values to be updated annually.

The climate factor will be based on an asset-level uncertainty score, which includes three key elements: sector-level stressors derived from the latest Eurosystem climate stress test, the debtor's exposure to transition-related uncertainties, and the residual maturity of the credit claim. The ECB added that the higher the sensitivity of the collateral to climate uncertainties, the greater the reduction applied to its collateral value.
