UBS will roll out the US leg of its new global advertising campaign in the fourth quarter, the Swiss bank has told this publication. It will encompass television, print, digital media and billboards.

The campaign, first reported by Dow Jones, carries the tag line “We will not rest.” It aims to repair relationships with clients, particularly at its private bank.

"We have restored our earnings power and are excellently positioned to deliver on our strategy. At the same time, we know that it will take more time and even more effort on our part before we fully regain the trust of our clients," according to an internal memo obtained by the news service.

The campaign debuts in Switzerland and Asia Pacific this week, and will launch in the rest of Europe as well as Africa in early September, the spokesperson said.

As previously reported, client outflows from the bank’s wealth management arm decelerated further in the second quarter to SFr5.2 billion (around $4.96 billion), compared with SFr8.0 in the previous three months.

UBS has suffered client withdrawals from its wealth management arm in the wake of huge credit market losses and a legal battle last year with the US authorities over a tax evasion case.
