Nomura's agency brokerage Instinet is to move all of its US staff into its Japanese parent's offices in New York, mirroring similar relocations already undertaken in Europe and Asia, and cementing the deeper integration between the two firms.

Instinet, which was acquired by Nomura in 2007, will move eight blocks from its current home on Avenue of the Americas in midtown New York to Nomura's offices at Worldwide Plaza by the end of the year, according to people familiar with the situation.
