Dresdner Kleinwort Wasserstein (DrKW), the investment bank, is to use Calypso Technology, a San Francisco-based firm, to build a single global securities processing platform.

The project as a whole covers the bank's cash equities and bonds businesses as well as its securities lending and borrowing operations, all of which fall within DrKW's capital markets business line. The project will be managed jointly by DrKW's IT and operations departments.
