This article presents a study of networks in the financial services market. We invoke network theory to study the role of connection between market actors within investment banking. We look at the relationship between corporate governance and the networks and performance of financial market actors. A comprehensive set of secondary data is analyzed with a multiple correspondence analysis methodology. The data is compared with evidences of rankings of the financial service divisions of investment banks. We have found that the forming of formal networks ties between market actors can be associated with the rating of financial banking service. Actors with more network connections are rated higher in customer ratings than those with fewer network ties. The forming of formal ties in boards and committees has a positive impact on the performance ratings of providers of financial services. Our data consists of three clusters. The first entails international banks with high turnover and superior customer reviews. The second cluster consists of small unranked banks with considerably lower turnover, and the third cluster is represented by the midsized banks.
