Credit Suisse and Instinet, the agency broker owned by Nomura Holdings, announced in May that they had agreed to link up their proprietary "dark liquidity pools" in Japan to enable their respective international clients to trade more efficiently in Japanese securities by executing larger trades with minimal market impact.
Dark pools are proprietary trading platforms that enable clients to trade in mainstream securities markets anonymously, often providing faster and more price-efficient execution.
The deal is the third between the two firms, with agreements already concluded to "pool pools" in Europe and the US.
