UBS AG (ADR) (UBS) Boots Bank of America Corp (BAC) from Top Spot

The world’s wealthiest people are returning to the private banks of some of the world’s largest banking institutions, a welcome turnaround from the depressed numbers private bankers have seen since the financial crisis. Competition is fierce, and as more moneyed customers are settling on just one bank for all of their banking needs, big banks are pulling in more clients.

Bank of America Corp (NYSE:BAC)

According to a new ranking by London-based wealth management watcher Scorpio Partnership, three U.S. banks made the list of the top private banks in the world, with Bank of America Corp (NYSE:BAC) in second place,  Wells Fargo & Co (NYSE:WFC) taking third, and Morgan Stanley (NYSE:MS) residing at No. 4.

Great news, indeed. For Bank of America Corp (NYSE:BAC), however, the announcement is less than joyful — since it points out the fact that Swiss bank UBS AG (ADR) (NYSE:UBS) now has the No. 1 spot, formerly occupied by Bank of America Corp (NYSE:BAC).

Private banking picks up steam
The study represents a stunning reversal for scandal-prone UBS AG (ADR) (NYSE:UBS), which posted a fourth-quarter loss in 2012 after a particularly bumpy year. The bank’s downsizing of its investment banking arm and concentration on its private banking section has paid off, though: UBS AG (ADR) (NYSE:UBS) clocked 9.7% in asset growth last year, compared with Bank of America Corp (NYSE:BAC)’s 5.6%.

Banks tailored for the super-rich have been ramping up lately as the ranks of the wealthy swell and private banks focus on managing this segment’s assets on a global basis. Citigroup Inc (NYSE:C), for instance, is bolstering its own presence in Asia and Latin America, and currently boasts a client list that includes 33% of the world’s billionaires.

Here at home, Morgan Stanley (NYSE:MS) has been courting well-heeled customers in upscale areas of states like in New York and Texas, bestowing jumbo mortgage loans and raking in big deposits through its Private Wealth Management arm.

Profits need a boost
Unfortunately, all of this activity hasn’t translated into more profits for these banks. Scorpio noted that profits climbed, on average, only 9.8% last year, versus 12.3% in 2011. Much of this is due to rising costs, according to the consulting firm. Both UBS AG (ADR) (NYSE:UBS) and Bank of America Corp (NYSE:BAC) have been concentrating on trimming expenses lately, and the study notes that diversified banks have done a better job at keeping costs down for banks that specialize in wealth management alone.

But emerging markets have represented fertile hunting grounds for private banks, which may explain why Bank of America Corp (NYSE:BAC) has slipped. While wealth inflows from North America, Europe, and Japan increased in 2012 by 5.9%, emerging markets saw growth of 12.9%, according to Bloomberg. Bank of America has sold its non-U.S. wealth management operations to Julius Baer, choosing to concentrate on the domestic front rather than try to boost the underperforming units.
