EU Investment Regulation

The EU investment-services rule family covering ISD, MiFID, MiFID II, and market-abuse controls.

EU Investment Regulation is the regulation landing page for EU investment-services rules, MiFID, MiFID II, market-abuse rules, AIFMD, ISD, and investor-protection frameworks. It keeps related terms in one branch so readers can move from a broad compliance question to the article that owns the regulatory evidence.

Use this page when EU investment regulation changes authorization, market access, transparency, conduct, or investor-protection duties. Use the parent Market Disclosure page when you need the broader regulation map. For an individual decision, confirm the rule source, jurisdiction, covered party, effective date, filing or record, and compliance consequence before relying on the term.

Example in Use

MiFID rules can affect how an investment firm classifies clients, discloses costs, and reports transactions.

What to Check

  • Directive or regulation, member-state implementation, covered service, instrument, client category, and firm authorization.
  • Trading venue, transparency duty, conduct rule, reporting obligation, market-abuse control, and marketing restriction.
  • Effective date, transitional provision, supervisory authority, and cross-border passporting issue.
  • Effect on investment services, fund marketing, transaction reporting, trading behavior, and compliance risk.

Common Mistakes

  • Treating EU directives and regulations as identical in implementation.
  • Ignoring client classification and instrument scope.
  • Assuming MiFID-style rules apply outside their jurisdiction without checking local law.
