Kernrechtsfrage
Whether the bank had a duty to provide daily margin-control tables and related FX risk documents under the mandate/accounting duty
Extrahierter Entscheid
The bank was not shown to have undertaken a specific duty to create and deliver daily margin-control reports; the requested tables were not part of the proven accounting obligation.
Extrahierte Begründung
The margin served to protect the bank, and the contractual documents showed discretionary margin setting. The evidence did not establish a special agreement obliging the bank to monitor and report margin daily for the client’s benefit.
