In 1973 he was a member of the Executive Board[1] and from 1977 he acted as spokesman for "Schweizerische Kreditanstalt" (SKA), of which he became chairman in 1982.
He held directorships with several international corporations, including Alusuisse, Bayer, Swiss Re, Swissair, Daimler Chrysler Switzerland, Ciba Geigy/Novartis, Elektrowatt, and Sulzer.
[3][4] Under Gut's leadership, SKA developed into a leading international financial services group with a focus on investment banking, asset management, and insurance.
In the Holocaust debate of the 1990s about dormant assets, he was committed to the creation of a humanitarian fund by the Swiss business community.
Thanks in large part to Gut, the settlement between the Swiss banks and the Jewish plaintiffs in New York was reached in 1998.
