Francesco Guerrera of the WSJ interviews Sergio Ermotti, CEO of Swiss bank UBS, and Andrea Orcel, the head of UBS investment bank. He asks Ermotti why the drastic restructuring at UBS, especially the downscaling of its investment banking operation. Ermotti says its because it was time to stop throwing money away on activity that did not cover the bank's cost of capital and the unhappiness of shareholders with the way UBS was operating. The string of bad news from UBS with legal settlements, trading scandals and huge losses have created a special situation at UBS which required drastic action. UBS was able to take the action also because of its successful wealth management business, which will become the core of its future business. Other banks such as Goldman Sachs and Morgan Stanley with large fixed income, currency and commodity (FICC) businesses, get more of their earnings from this unit and are less likely to follow UBS.
