The Investment Services Directive (ISD) of 1993 provided a regulatory framework for securities dealing within the European Union. It established that securities firms admitted by their domestic regulator could operate throughout Europe. From 2007, the ISD was superseded by the Markets in Financial Instruments Directive (MiFID), which further consolidated the single market for financial services.
The Investment Services Directive (ISD) was a directive of the European Union aimed at creating a single market in investment services and fostering financial integration across member states.
