Designated Self-Regulatory Organization (DSRO)

Self-regulatory organizations (i.e., the commodity exchanges and registered futures associations) must enforce minimum financial and reporting requirements for their members, among other responsibilities outlined in the CFTC 's regulations. When a Futures Commission Merchant (FCM) is a member of more than one SRO, the SROs may decide among themselves which of them will assume primary responsibility for these regulatory duties and, upon approval of the plan by the Commission, be appointed the "designated self-regulatory organization" for that FCM.
