HONG KONG/LONDON (Reuters) – Incoming Credit Suisse boss Tidjane Thiam is expected to focus on private banking in Asia while aggressively cutting jobs at its investment bank, as he aims to repeat the success in the region of his old employer, Prudential. Thiam could slash 3,000 jobs from Credit Suisse’s investment bank, or 15 percent of staff globally, and cut 150 billion Swiss francs ($149 billion) of assets from the bank’s fixed income, commodities and currencies business as part of that shift, analysts at JPMorgan said.
