UBS AG, Switzerland's largest bank, will cut as many as 10,000 jobs companywide as the trading business shrinks, a person with knowledge of the plan said.

Many of the reductions will come in the trading businesses overseen by investment-bank co-head Carsten Kengeter and probably will occur over several quarters, said the person, who requested anonymity. An announcement may come when UBS reports third-quarter earnings on Oct 30, the person said.

Chief Executive Officer Sergio Ermotti, 52, is overhauling the bank as Swiss regulators pressure UBS and Credit Suisse Group AG to boost capital and scale back trading and investment-banking operations. Like rival securities firms, UBS has been struggling to boost profitability as client activity and trading remain sluggish.

"It was a loser's game for them," said Terry Connelly, former dean of the Ageno School of Business at Golden Gate University in San Francisco and an ex-managing director at Salomon Brothers Inc. "It wasn't their fault. They simply tried climbing the wrong mountain." High fixed costs and weak demand have made it harder to be profitable and the industry will have to shrink more, he said.

Ermotti told his staff in a memo this month he'll do whatever it takes "to tackle the current challenging market environment and paradigm shift" in banking and will continue "remodeling" UBS. He said in July that the market environment has completely changed since the firm announced reorganization plans for the securities unit in November.

"UBS is a microcosm for the industry," Mark Williams, a lecturer at Boston University's School of Management, said in an interview. "The banking business model is changing and we've got to look at cost structure. We've got to look at compensation and we've got to readjust."

The bank had about 63,250 employees as of June 30, according to its most recent financial report, which means the staff cut could equal 16 percent. UBS already announced it is reducing risk-weighted assets at the investment bank by more than half from September 2011 levels, mostly in fixed income.

The plan will lead to a further reduction of as much as 100 billion Swiss francs ($107 billion) of risk-weighted assets, the person said. Much of the fixed-income operations will be put in a new unit that will hold non-core assets. Carsten Kengeter, currently co-CEO of the investment bank, will probably give up his current role to head the new unit, the person said.

The remaining businesses at the investment bank will include a slimmed-down advisory unit, equities trading and research, foreign exchange, government debt trading and limited credit and corporate bond trading, according to the person familiar with the bank's plans. Capital demands by Swiss regulators, among the strictest in the world, are making it hard for UBS to compete in capital-intensive businesses such as fixed-income trading.
