Julius Baer (BAER.VX) expects to strike a deal with U.S. authorities in a matter of months to settle a criminal investigation into the Swiss bank’s role in helping wealthy Americans evade their taxes, its chief executive said on Monday. Shares in the Zurich-based lender shot up 7 percent on the news, recovering much of the ground lost since larger rival Credit Suisse (CSGN.VX) settled its U.S. tax case in May for $2.5 billion, more than double what the bank had set aside for the purpose.
