Clearstream

Clearstream is one of the world's two leading international central securities depositories (ICSDs), operating as a specialized post-trade infrastructure provider. Based in Luxembourg, Clearstream Banking S.A. is a fully-owned subsidiary of Deutsche Börse Group, serving over 2,500 institutional customers across 110 countries. The institution specializes in securities settlement, custody, and asset servicing across all asset classes, with approximately €20 trillion in assets under custody.

Clearstream functions as a "bank for banks" rather than a retail institution, exclusively serving central banks and AML-regulated credit institutions. It plays a critical role in the global Eurobond market, which represents the world's third-largest debt market with over €14 trillion in outstanding securities.
