Credit Suisse Group AG is seeking to gain full control over its securities venture and plans to double its headcount and revenue in the world’s fastest growing major economy. UBS Group AG also wants to double its China footprint in three to five years, and is seeking to deepen control over its Chinese securities unit. Barclays Plc Chief Executive Officer Jes Staley said on Tuesday the bank is looking to build on its small presence in China, while continuing to invest in capital markets, an area that has brought in strong growth during the pandemic. But challenges abound. Foreign banks have to navigate a murky regulatory system. Despite China allowing them to apply for full ownership of their partnerships a year ago, none of them have yet been able to secure that. They also have to battle with uncertainty — as was the case when Ant Group Co.’s initial public offering was derailed days before its scheduled trading debut, putting millions in fees at risk.
