Credit Suisse reported Thursday that third-quarter profit more than doubled to Sfr1.03 billion ($1.07 billion), as the Swiss bank streamlined its wealth management business and enjoyed a sharp increase in debt-trading revenues.

Credit Suisse said net revenues rose 20% to Sfr6.54 billion, which like the bank's profit figure was ahead of expectations. Analysts had expected Credit Suisse to post a profit of Sfr859 million on net revenue of Sfr6.17 billion for the quarter.
