ZURICH/LONDON (Reuters) – When Tidjane Thiam unveils his plans for Credit Suisse on Wednesday the Swiss bank’s new chief executive will likely rest his case on three Cs: capital, cuts and charm. Thiam will show his hand after taking the reins at Zurich-based Credit Suisse in July from British insurer Prudential. Investors expect him to refocus the bank’s business toward wealth management and asset management, while shrinking its investment bank and closing the capital gap on rivals.
