Basel IV

Basel III revisions are complex, covering greater compliance obligations as well as more stringent capital requirements which will affect balance sheets and P&L statements. No wonder the revisions are often referred to as Basel IV. However, there is an upside: the level of required integration is so thorough that firms which execute it effectively should improve their business efficiency, not just fulfill their regulatory burden.

Basel IV – A Holistic Approach


  • Consistency of all calculations, irrespective of their purpose, e.g. RWA, leverage ratio, liquidity, large exposures and IRRBB.
  • Proportionality of each type of risk; calculation methods will vary depending on the level of risk.
  • Continuous compliance; meeting the regulatory requirements “at all times”.
  • Output floor: RWA using internal models must be at least 72.5% of capital with standardized methods.
