UBS AG, Switzerland's biggest lender, is close to agreements with regulators to pay more than 290 million pounds ($465 million) to settle allegations traders tried to rig global interest rates, a person with knowledge of the talks said.

An announcement may come as soon as next week, said the person, who declined to be identified because the talks are private. More than 25 people have already left UBS after the lender's own internal probe, another person said last month.

Global authorities are investigating claims that more than a dozen banks altered submissions used to set benchmark such as the London interbank offered rate to profit from bets on interest-rate derivatives or make the lenders' finances appear healthier. UBS's is fine is likely to surpass the 290 million pounds Barclays Plc, the U.K.'s second-biggest bank, paid in June to settle claims it attempted to manipulate Libor.
