The report did not, however, specify how the private banking operations of Credit Suisse will be affected by any sale.

The Zurich-listed bank this week has instructed CB Richard Ellis, the property advisory and investment firm, to begin marketing the smaller of its two buildings in Canary Wharf, with indications that its landmark tower at Cabot Square is also likely to be brought to the market before the end of the year, the FT said. The sales of the two buildings could raise more than £500 million.

Credit Suisse declined to comment.

A number of banks are looking to sell assets they regard as “non-core” in order to slim down their businesses and rebuild balance sheets. Typically, the property disposals will be handled via a sale and leaseback arrangement.
