A veteran UBS communications expert in the U.S. has turned up in a new role – at crosstown rival Credit Suisse, where the equivalent department has undergone a severe churn recently.

Karina Byrne was UBS' head of media relations in the Americas for almost ten years before leaving that job last December.

As chief spokesperson for all three of the Swiss bank's units in the U.S., she ushered the bank through crises such as the one involving Dillon Read Capital Management, an emergency bailout by the Swiss government during the financial crisis, and 2011's dramatic restructuring of its investment bank.

Near-Identical Role as at UBS

Byrne, who started her career as a reporter in Canada, worked at the New York Stock Exchange briefly earlier this year.

She has surfaced at Credit Suisse in a near-identical role to the one she held at UBS. The move is a coup for Credit Suisse, which has seen extremely high turnover of communication professionals in the past two years.

Byrne began this month at Credit Suisse, where she is head of communications for the Americas and of IHC, a U.S.-based holding company related to recovery and resolution measures required by regulators.
