Royal Bank of Canada said it would pay $10.1b for HSBC Holdings PLC’s Canadian operations, a move meant to position Canada’s biggest bank to expand during an expected immigration surge. Canada’s government has said it expects to boost immigration to 500,000 people a year by 2025, up from 405,000 last year. The HSBC deal, RBC CEO Dave McKay said, isn’t about acquiring loans or deposits as much as acquiring clients.
