A team of Citigroup Inc. derivatives traders generated about$300 million of revenue this year, thriving from serving companiesand investors trying to anticipate central bank decisions,according to people with direct knowledge of the matter.

The windfall was produced by the bank's U.S. dollarinterest-rate swaps desk led by Geoff Weber in New York, accordingto the people, who asked not to be identified because the firmdoesn't break out results for such businesses. The group includesDan Leadbetter, Daniel Gottlander and Mark Zaguskin, one personsaid.

The team's performance demonstrates that traders can still makeoutsize profits even after regulators sought to curb risk-taking inthe wake of the financial crisis. Another example: Goldman SachsGroup Inc. trader Thomas Malafronte earned more than $100 millionby scooping up cheap junk debt early this year.
