(7)In order to promote best supervisory practices in the internal market, it is fundamentally important that the single rulebook be accompanied by a European supervisory handbook on the supervision of financial institutions, drawn up by EBA in consultation with the competent authorities. That supervisory handbook should identify best practices across the Union as regards supervisory methodologies and processes to achieve adherence to core international and Union principles. The handbook should not take the form of legally binding acts or restrict judgement-led supervision. It should cover all matters which are within EBA's remit, including, to the extent applicable, consumer protection and the fight against money laundering. It should set out metrics and methodologies for risk assessment, early warnings and criteria for supervisory action. Competent authorities should use the handbook. The use of the handbook should be considered as a significant element in the assessment of the convergence of supervisory practices and for the peer review under Regulation (EU) No 1093/2010.
