Throughout the 1990s, SBC engaged in a large growth initiative, shifting its focus from traditional commercial banking into investment banking, in an effort to match its larger Swiss rival Credit Suisse. As part of this strategy, SBC acquired US-based investment bank Dillon Read & Co. as well as London-based merchant bank S.G. Warburg in the mid-1990s. SBC also acquired Chicago-based Brinson Partners and O'Connor & Associates.
