For the financial system to be stable, institutions must have adequate capital and liquidity, and manage these levels effectively. It is thus crucial that they comply with supervisory requirements by establishing an Internal Capital Adequacy Assessment Process (ICAAP) to ensure capital adequacy and an Internal Liquidity Adequacy Assessment Process (ILAAP) to ensure liquidity adequacy.

Bundesbank collects ICAAP and ILAAP information for SREP purposes on an annual basis (as of 31st December). Relevant information is provided by LSIs via an XBRL based reporting system without delivery of internal documents or use of ‚reader‘s manuals‘. The reporting framework is designed to facilitate the prudential assessment without compromising the flexibbility in the choice of methods within Pillar 2. Structural ICAAP and ILAAP information provide a vital input for the assessment of the individual institution as well as for the identification of sector wide developments and a range of practices in terms of ICAAP and ILAAP.
