The move comes after Nomura, Japan's top brokerage and investment bank, reviewed its prime brokerage business and vowed to enhance risk management in the wake of the Archegos loss.
Specifically, Nomura plans to stop prime brokerage services using U.S. and European cash stocks, the source said. The person declined to be identified as the matter was private.
The bank will continue cash-prime brokerage services with Japanese and Asia stocks, as well as the prime brokerage business with U.S. stock derivatives, where the bank has strengths, the source said.
Nomura declined to comment.
