Goldman has maintained a Boston fixed-income sales office since the 1970s, according to one hedge fund manager. The closing is part of an ongoing trend affecting the satellite offices of all major investment banks, according to a salesman, who notes that small bureaus in cities such as Atlanta and Minneapolis have been closed in recent years. ABN AMRO, for one, recently closed down its San Francisco sales office and plans to cover West Coast accounts from Chicago (BW, 2/16). The salesman says banks are deciding to shut down offices for cost purposes and because they believe it is more important for a sales force to be physically located near their traders rather than their customers.
