Argentina’s Securities Commission (CNV) has issued a new reporting regime requiring markets to provide regular data on open positions in futures and options contracts, aimed at strengthening derivatives risk monitoring in the capital market. Under the rules, markets must submit weekly reports to the CNV within two days after each week ends, covering detailed open-position information for Clearing and Settlement Agents (ALyC), excluding those that are direct participants or financial institutions authorised under the Financial Entities Law. The obligation also excludes persons covered by the concept of an expanded proprietary portfolio. Implementation is phased: historical information for August 2025 to January 2026 must be submitted with weekly granularity, while data from 1 February 2026 must be captured with daily detail but still reported weekly.
