The OCC, the Board, and the FDIC are inviting public comment on a notice of proposed rulemaking (proposal) that would substantially revise the capital requirements applicable to large banking organizations and to banking organizations with significant trading activity. The revisions set forth in the proposal would improve the calculation of risk-based capital requirements to better reflect the risks of these banking organizations' exposures, reduce the complexity of the framework, enhance the consistency of requirements across these banking organizations, and facilitate more effective supervisory and market assessments of capital adequacy.
