At the moment, Belgium is the only country in Europe that prohibits the distribution of certain derivatives to retail investors.
The problem of the offer of binary options, CFDs and forex instruments is not a purely Belgian phenomenon. It arises throughout Europe. In this regard, please see a recent warning by the European supervisory authority, ESMA.
Some other countries have taken restrictive measures relating to the distribution of such instruments (see also question no. 1 above).
The French supervisory authority, the AMF, recently prohibited a foreign provider of binary options, CFDs and forex instruments to continue offering investment services within France.
