Market abuse

Published: 30/03/2015     Last Modified: 04/11/2015
Certain types of behaviour, such as insider dealing and market manipulation, can amount to market abuse. Types of conduct constituting market abuse are set out in section 118 of the Financial Services and Markets Act 2000 and in the Market Abuse Directive.

This legislation aims to reduce instances of market abuse and as a result protect the integrity of the financial markets and increase investor confidence.

A Market Abuse Factsheet gives a summary of the types of behaviour that can constitute market abuse.

The Code of Market Conduct (known as MAR 1) provides more detail of these types of conduct.

The Suspicious Transaction Reporting page gives information about the obligation on firms dealing in certain financial instruments to report suspicious transactions to the FCA. Suspicious transactions are those where there is a reasonable suspicion of market abuse.

Market Abuse Regulation (MAR)

In June 2014 new European legislation seeking to strengthen the fight against market abuse was agreed. The Market Abuse Regulation (MAR) will apply in the UK and across the EU from 3 July 2016.

To prepare you for these changes we held a Market Abuse Regulation briefing on 24 March 2015 which we recorded. All information was correct as of 24 March 2015.

Read more about MAR.

Market Conduct

The Market Conduct page gives information about the standards of conduct required in the financial markets.

The Market Conduct Sourcebook (MAR) in the FCA Handbook contains rules and guidance about the standards of conduct required in the financial markets.
