UBS is expected to announce Monday the hiring of two executives from Goldman Sachs and Bank of America who will push to make more mortgages and other loans through the Swiss bank's brokerage force in the US.

The move is the latest effort by Robert McCann, UBS's wealth management chief in the US, to rejuvenate the brokerage unit. Since taking the job last year, the former Merrill Lynch brokerage chief has slowed the outflow of client money but needs new sources of revenue growth.
