Swiss Miss: Why UBS’s deal with Credit Suisse will threaten its hold on rich clients

• UBS was already a giant in wealth management before it agreed to buy doomed rival Credit Suisse.

• Whether clients stay or go depends on how quickly UBS can cure Credit Suisse’s woes.

UBS was already the largest private wealth manager in the world before it agreed to buy fellow Swiss bank Credit Suisse. A forced merger will now broaden UBS’s already sprawling client base, but it will also invite challenges for its wealth brand across the globe.
