Basel III Monitoring Report - Results of the cumulative quantitative impact study.


Alongside the finalisation of the Basel III post-crisis reforms, the Basel Committee published the results of a cumulative quantitative impact study (QIS) conducted while developing the standards. The Committee believes that the information contained in the report will provide relevant stakeholders with a useful benchmark for analysis and provide an estimated impact of the Committee's finalisation of the BaselIII reforms.

The QIS is based on end-2015 data provided by 248 banks that participated in the exercise. The QIS did not take into account any transitional arrangements, nor make any assumptions about banks' profitability or behavioural responses. The report also does not reflect any additional capital requirements under Pillar 2 of the Basel II framework, any higher loss absorbency requirements for domestic systemically important banks or any countercyclical capital buffer requirements. Such factors may result in the report overstating the actual impact. On that basis, the report shows that the finalisation of BaselIII results in no significant increase in overall capital requirements, although effects vary among banks.
