The scope of the planned resolution regime was not limited to large domestic banks. In addition to "systemically significant or critical" financial institutions, the scope also applies to two further categories of institutions Global SIFIs (banks incorporated domestically in a country that is implementing the bail-in regime) and "Financial Market Infrastructures (FMIs)" like clearing houses. The inclusion of FMIs in potential bail-ins is in itself a major departure. The FSB defines those market infrastructures to include multilateral securities and derivatives clearing and settlement systems and a whole host of exchange and transaction systems, such as payment systems, central securities depositories, and trade depositories. That would mean that an unsecured creditor claim to, for example, a clearing house institution or a stock exchange could in theory be affected if such an institution needed to be bailed in.
