AI Summary of Article 103 Management of the trading book

Institutions are mandated to establish comprehensive policies and procedures for the effective management of their trading books. This includes defining trading activities, daily marking-to-market capabilities, and the identification and hedging of material risks, particularly for model-marked positions. Legal and operational constraints impacting liquidation or hedging in the short term must also be considered.

Furthermore, firms must document and approve a clear trading strategy, set position limits, and ensure active monitoring of positions against this strategy. These measures aid in mitigating risks and enhancing compliance within the regulatory framework.
