Between 2001-2009 he was Governor of the Washington-based International Monetary Fund (IMF) for Switzerland and chairman of the board of directors of the Bank for International Settlements (BIS) in Basel.
Roth has been credited with the measures taken to restore public confidence in the Swiss banking system and blamed for destroying the Swiss franc. Although he certainly had input into the measures implemented by the Swiss banking system and the Swiss government, he certainly did not single-handedly do either.
Roth is married and has three children. In 2009, he took an early retirement. He and his wife live in Geneva.
