There is now widespread acceptance that digital assets are going to co-exist alongside traditional assets for a long time. That implies that issuers and investors will need a market infrastructure that renders issuers indifferent as to whether a source of liquidity is digital or traditional and investors indifferent as to whether an exposure is available in digital form or in traditional form. Both sides of the market just need something that works efficiently at low cost with minimal disruption to the status quo. D7, the Cloud-based post-trade infrastructure Clearstream is building to link the digital and the traditional securities markets, aims to provide exactly that. Dominic Hobson, Co-founder of Future of Finance, spoke to Michael Crezelius, Head of the Issuer CSD at Clearstream, and Thilo Derenbach, Head of Commercialisation and Digitisation at Clearstream, about how D7 does what it does now – the service is in production already – and what it will do in the future.
