New UBS chief financial officer John Cryan is among a four-strong crack team assembled by group chief executive Marcel Rohner to oversee the bank’s path back to health after a year of billion dollar writedowns that have rocked the Swiss group.

Cryan, who has spent more than 20 years with UBS having worked for Warburg Dillon Read before it became part of the Swiss group, was yesterday named group CFO in a raft of executive and board changes, and as such he will play a vital role in helping Rohner put into action UBS' remediation plan aimed at addressing the business and structural issues that contributed to the bank's problems.
