Abstract:

The European Market Abuse Regulation (‘MAR’) is the regulatory framework for preserving market integrity and investor confidence in financial instruments admitted to trading by preventing insider dealing, unlawful disclosure of inside information and market manipulation.
Since its entry into force in 2016, MAR has harmonised the regulation of insider trading and market manipulation in financial markets at European level, putting an end to the different interpretations of the rules by each of the European Member States.
The reform of MAR introduced by the Listing Act Regulation increases the legal clarity of the rules and reduces disproportionate requirements for issuers, with a view to increasing the attractiveness of the European Union’s capital markets.
In addition, the Regulation on crypto-asset markets (‘MiCA’) introduces a regime parallel to that of MAR, establishing specific rules on market abuse applicable to crypto-assets admitted to trading.

Keywords: Capital markets, Market Abuse, Disclosure of inside information, Market soundings, crypto-assets.
