Questione giuridica chiave
Whether the bank had a contractual duty to monitor margin and inform the client regularly of margin shortfalls
Decisione estratta
No. The contractual terms placed the burden on the client; the bank had no duty to follow margin changes or give systematic warnings.
Motivazione estratta
The special conditions reserved market rules only for market transactions, not the internal bank-client relationship, and expressly stated that the bank was not obliged to warn of insufficient margin. The margin instrument protected the bank, not the client.
