(59)Asset-referenced tokens and e-money tokens should be deemed significant when they meet, or are likely to meet, certain criteria, including a large customer base, a high market capitalisation, or a large number of transactions. As such, they could be used by a large number of holders and their use could raise specific challenges in terms of financial stability, monetary policy transmission or monetary sovereignty. Those significant asset-referenced tokens and e-money tokens should, therefore, be subject to more stringent requirements than asset-referenced tokens or e-money tokens that are not deemed significant. In particular, issuers of significant asset-referenced tokens should be subject to higher capital requirements, to interoperability requirements and they should establish a liquidity management policy. The appropriateness of the thresholds to classify an asset-referenced token or e-money token as significant should be reviewed by the Commission as part of its review of the application of this Regulation. That review should, where appropriate, be accompanied by a legislative proposal.
