Global Consumer Banking revenues increased 3 percent to $8.43 billion, while Corporate/Other revenue fell 55 percent from a year ago to $509 million. JPMorgan also had to set aside more money in the quarter to cover souring credit card loans.
Citi cited "continued growth in loans and assets under management" for the rise, as well as higher interest rates.
Citigroup's cost of credit rose 15 percent from past year to $1.99 billion, driven by an increase in net credit losses of $252 million and higher loan loss reserve build of $16 million that included about $100 million of hurricane and earthquake-related loan loss reserve builds.
Trading revenue during the fourth quarter of 2016 benefited from a surge in trading activity following the US election.
