The Council of the European Union on Monday adopted new regulations imposing a legal framework on credit-rating agencies and introducing the requirement of 5% risk retention by originators. A major directive within the new regulations tightens capital requirements for European banks. In an effort to improve the framework for securitization practices, the regulation requires originators to retain 5% of risk transferred or sold to investors. Trade groups Stateside remain categorically opposed to a 5% risk retention. The European rules also strengthen supervision of cross-border banking groups, harmonize the classification of banks' Tier 1 capital funds with hybrid instruments, introduce rules on liquidity risk management and tighten the supervision of exposure to a single counterparty. Another new regulation aims to ensure the credit-rating agencies (CRAs) avoid conflicts of interest or at least manage them properly, to improve the methodologies used by CRAs and the quality of their ratings and to increase transparency by setting disclosure obligations for CRAs. The regulation provides for a legally-binding registration and surveillance system for CRAs intended for use in the regulatory process.
