EFG International AG, a private-banking boutique based in Zurich, is expanding its 300-person team serving clients from the Americas with an emphasis on Brazil and South Florida.

Wealth under management from the Americas increased faster than any of EFG’s other regions last year, bringing in $4 billion, according to Sanjin Mohorovic, chief executive officer of the firm’s EFG Capital brokerage in Miami and head of the company’s Americas operation.
