Another senior Goldman Sachs executive is leaving — and colleagues are vexed

Yet another senior executive is leaving Goldman Sachs — and, of course, his co-workers are once again putting the exit under a microscope.

Michael Swell, head of global fixed-income portfolio management at the Wall Street giant’s asset management division, is set to retire at the end of the year, according to a memo from late last month that was obtained by The Post. That’s despite Swell being just 55 years old, and getting high marks during his 14-year tenure (He made partner in 2012 after joining the firm in 2007). Last week, Goldman Sachs Asset Management, also known as GSAM, reported a record quarter, raking in $5.13 billion in net revenue.
