• ESA guidelines (comply or explain)ESA guidelines are Level 3 texts issued by the EBA, ESMA or EIOPA under Article 16 of their founding regulations to set consistent supervisory practice. National authorities must state within two months whether they comply or intend to comply, or explain why not, and firms must make every effort to comply.
• Single rulebookThe single rulebook is the set of harmonised prudential and conduct rules that apply to financial institutions across the EU: Level 1 acts such as the CRR and CRD, the technical standards adopted under them, and ESA guidelines and Q&As. It aims to remove national differences inside the single market.
• European Supervisory Authorities (ESAs)The European Supervisory Authorities are the EBA (banking), ESMA (securities and markets) and EIOPA (insurance and pensions), created in 2011. They draft technical standards, issue guidelines and Q&As, coordinate national supervisors and, in some areas, supervise firms directly. Their Joint Committee handles cross-sector work.
