EBU Single Rulebook Q&A 14 August 2013 2013_157 Scope of application of Articles 341 to 344 of Regulation (EU) No. 575/2013 (CRR)

Article 341 starts with "The institution shall separately sum all its net long positions and all its net short positions in accordance with Article 327.". Does "all positions" also include positions in the banking book, or are Articles 341-344 only valid for positions in the trading book? Would like certainty about the scope of application of Articles 341 to 344.
