It's been another long goodbye at Goldman Sachs. : One thing that can be said about Goldman Sachs is that it lets its senior people go gently. There are very few of the ruthless overnight ejections seen at some other firms, and instead plenty of meandering departures culminating in a ‘retirement’ that is nonetheless often followed by the retiree taking a job elsewhere. It’s not clear whether Kostas Pantazopoulos, Goldman’s former head of rates trading is intending to go onto something else (maybe a macro hedge fund? ), but insiders say he has retired, and his departure has been rather circuitous.
