European Banks Confront ECB Over Climate Factor Transparency

The European Central Bank's climate factor has sparked controversy among Europe's biggest banks. The central bank introduced a discount, or 'haircut,' to account for risks associated with low-carbon transition. However, the banking sector is pushing back over the lack of transparency in how these adjustments are calculated.

The climate factor adds an additional layer to the haircut applied to collateral values. This means that assets with higher exposure to transition risks will have a reduced collateral value. The European Banking Federation is demanding that the ECB reveal the full methodology behind the climate factor, citing that banks need visibility into how it's calculated to manage liquidity and collateral strategies effectively.

The ECB has argued that these adjustments are based on sector-level stressors rather than individual company assessments. They claim that they're applying assumptions about transition risk at a broader level, not grading each bond issuer on its carbon footprint.
