ESMA Shifts to Single Volume Cap Mechanism for EU Trading Venues

The European Securities and Markets Authority (ESMA) is overhauling its trading volume oversight, replacing the dual-cap system with a streamlined single volume cap mechanism (VCM) starting October. The new framework imposes a 7% ceiling on trading volume under the reference price waiver—calculated against total EU equity trading activity over the preceding year. Breaches will trigger three-month trading suspensions for non-compliant instruments.

Transaction reporting burdens will ease as National Competent Authorities assume data collection responsibilities, phasing out the legacy DVCM reporting system by January 2026. ESMA's forthcoming VCM data portal will centralize compliance monitoring, with technical adjustments to Regulatory Technical Standard 3 (RTS 3) progressing independently of the October implementation deadline.
