Morgan Stanley employs almost 50,000 people and Goldman Sachs had about 30,000 staff last year.
According to analysts as many as 300,000 people could have lost their jobs in the global financial services sector globally by the end of 2009, with as many as 25% of that total drawn from IT professionals.
This is the result of mergers being completed and companies preparingfor a slowdown in business.
Ralph Silva, analyst at Towergroup, said thebanks weredoing 25% less business and as a result the cuts wereunsurprising.
"I would not be surprised by more lay-offs and I think they will be in all areas of the business in equal numbers. Therefore operations (including IT) and customer-facing staff will be hit in equal numbers," added Silva.
