The European Central Bank (ECB) has decided to extend the use of climate factors in the Eurosystem collateral framework to certain eligible credit claims whose debtor is a non-financial corporation. This extension aims to strengthen the Eurosystem's risk management framework by addressing financial uncertainties related to the green transition. The measure builds on the introduction of a climate factor for marketable assets issued by non-financial corporations and their affiliated entities, which was approved in July 2025 and became effective on 15 June 2026. The climate factor will be based on an asset-level uncertainty score comprising three elements: a sector-level stressor 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 maximum additional reduction in the final collateral value, including both bonds and credit claims, will be 5%. This measure is expected to be implemented at the earliest by the end of 2027, with climate factor values updated annually. The ECB's decision is designed to protect the Eurosystem against potential declines in collateral value due to climate-related transition shocks, such as changes in climate policy, technological developments, shifts in consumer behavior, litigation, and broader macroeconomic adjustments. The extension complements the existing risk control framework and increases the resilience of monetary policy implementation. The ECB will rely on sector-level data or alternative data suited to assess the risks in question, where industry-level or debtor-level data are unavailable. Climate factors for individual credit claims will not be publicly disclosed.
