The civil market abuse regime in the United Kingdom (UK) is changing. From 3 July 2016 the majority of the requirements under the European Union’s Market Abuse Regulation (MAR) come into effect. Although MAR runs in tandem with the European Directive on Criminal Sanctions for Market Abuse, the UK is not implementing this directive, so there will be no change to the UK’s criminal market abuse regime. There are three market abuse behaviours specified in MAR: insider dealing, unlawful disclosure of inside information and market manipulation. These behaviours are specifically prohibited, subject to certain carve-outs.
