The European Banking Authority, in its Basel III full implementation impact report11 found that European banks’ Tier 1 capital requirements would increase by 15% as a 1result of Basel III changes, with the proposals for an output floor being responsible for a 7.1% overall rise.

Other capital requirements specific to securitisations are also considered.1 1
