Citigroup said its trading revenue is performing above expectations so far in the third quarter.

Chief financial officer John Gerspach, speaking at a financial services conference on September 14, said that trading revenue would be up by mid-single digits compared to a year ago, driven by strength in rates and currencies. Gerspach didn't go into details, but Citi has traditionally relied on its large fixed-income trading shop more than its smaller equities division.
