Confidence is essential for properly functioning equity, bond and derivatives markets. As authorized exchanges, all OMX exchanges are supervised by the respective local Financial Supervisory Authority. The Nordic Exchange is responsible for establishing clear rules and regulations and for ensuring that they are followed. The Surveillance department within OMX is separate from business operations.

Rules and regulations that affect the trading and listing are:

Norex Member Rules – regulate membership and trading.
Rules and Regulations of OMX Derivatives Markets – regulate derivatives trading and clearing.
Issuer Rules – regulate listing of shares and other financial instruments.
