The Board of Governors of the Federal Reserve System (Board) is publishing a final rule revising the risk-management standards in its Regulation HH, Designated Financial Market Utilities. The Board is replacing the existing two sets of risk-management standards for payment systems and for central securities depositories and central counterparties with a common set of risk-management standards for all types of designated financial market utilities (FMUs) and making conforming changes to the definitions. The new common set of risk- management standards and the definitions are based on the Principles for Financial Market Infrastructures (PFMI), which were developed by the Committee on Payment and Settlement Systems (CPSS) and the Technical Committee of the International Organization of Securities Commissions (IOSCO) and published in April 2012.
