Question juridique clé
Whether the bank breached contractual duties by agreeing to a reduced margin in speculative foreign-exchange financing.
Solution extraite
No. A reduced margin mainly protects the bank against client insolvency; where the client agreed to it and understood the speculative risk, the bank did not breach its duties.
Motifs extraits
Without a management mandate, the bank executing instructions has no general duty to protect the client’s interests. The cantonal findings showed the margin reduction was agreed and the client understood the strategy and its risks.
