National Councillor and President of the Committees for Economic Affairs and Taxation (CEAT) Christophe Darbellay gestures during a news conference on the resignation of Swiss National Bank (SNB) Chairman Philipp Hildebrand, in Bern January 9, 2012. Hildebrand resigned with immediate effect on Monday, relinquising one of the world's top 10 central banking jobs because he has been unable to prove he was unaware of a $418,000 currency trade made by his wife.
