Financial Services The Impact of Basel III on Korean Financial Services Disclaimer This report was produced by Oliver Wyman on behalf of the Financial Supervisory Service. The figures presented in this report are based on outside- in analysis, using public data sources and internal Oliver Wyman reference data. The report aims to be neutral about the need for and merits of the new Basel III regulation, and to be purely factual about its strategic implications on the Korean banking landscape. The implications are hypotheses on behalf of Oliver Wyman and do not necessarily reflect the FSS’s own judgments; neither do they promise nor preclude any FSS action.
