The banking industry listed its major worries.

Losses from bad loans and the burgeoning federal budget deficit topped the list of critical concerns of the top officers at the biggest banks in the United States, according to a survey conducted by Egon Zehnder International, a Zurich, Switzerland-based management consulting firm. There were 840 respondents to the survey, which contacted the 2,394 chief executives of all U.S. commercial banks with more than $100 million in assets. The survey also ranked Citibank, Morgan Guaranty Trust and Wachovia Bank & Trust as the three best-managed banks in the country.
