Patrick Ramsey, head of Barclays Bank Suisse, said that the firm reported a rise of almost CHF18 billion in 2011, which also included funds booked outside Switzerland.
The positive result of the firm has encouraged it to hire more Swiss-based relationship managers in the year 2012.
"Switzerland is one of the main hubs for the growth of Barclays in the future," Ramsey, as quoted by Bloomberg, said.
In 2011, the number of employees servicing wealthy private clients increased from 14 to 57 and Ramsey expects the numbers to go up to 70 to 80 bankers in the year 2012.
Barclays is also planning to expand beyond its traditional base of non-UK domiciled clients and will target regions such as Latin America, Africa and Russia.
