The financial services space is a well-regulated space the world over and are expected to operate in a completely transparent manner. High capital requirements for entry generally limit participation to a number of large players. Many of the players also have vast consumer franchises. Moreover, since they deal with money, the security requirements are high.
With this combination of expectations and markets, automation, where possible, becomes essential. On account of the sensitivity related to security and confidentiality, much of the work needs to be done by inhouse resources. The width of IT talent that works for an established financial services organisation could put a mid-size IT company to shame.
