Jacques de Saussure, designated senior partner of Pictet - one of Switzerland's largest private banks - told the Financial Times that there is "growing optimism" about the country's position as a wealth management center.
"There are suddenly new reasons for having your assets in Switzerland," he said.
He stated that the current economic uncertainty affecting the eurozone is having a big impact on the performance of the country's private banks.
His comments have been backed up by a recent report by Boston Consulting Group (BCG).
Matthias Naumann, BCG's managing partner for Switzerland, said: "Given the current uncertainty in the eurozone, there is a trend for customers to move additional declared money to Switzerland."
Last month, members of the eurozone signed up to a â¬750 billion ($975 billion) bailout package designed to calm market fears about the financial troubles of Greece spreading to other member states.
