The European Central Bank (ECB) has implemented several adjustments to its operational and regulatory frameworks. Initially, the ECB modified its repo collateral framework for private-sector assets, opting to use the second-best rating from external agencies as a reference point rather than the highest rating. This change impacts the calculation of valuation haircuts for assets such as unsecured bank bonds, covered bonds, and non-financial corporate or non-Eurozone public sector assets. The ECB also introduced a climate factor into the Eurosystem’s collateral framework.

Subsequently, the ECB proposed easing regulatory and supervisory requirements for small and non-complex institutions (SNCIs) to ensure proportionality. This includes a proposal to allow national authorities to increase the asset threshold for ‘small’ bank classification from 5 billion euros to 10 billion euros, which could bring approximately 150 more banks into the simplified regime. To reduce administrative burdens, the ECB suggested reducing financial data reporting fields from 13,500 to 700 and transitioning toward more efficient top-down stress tests.
