JP Morgan Chase posts $5.6bn profit
US banking giant JP Morgan Chase has reported a $5.6bn (£3.5bn) profit for the three months to 30 September.
The quarterly results represent a marked improvement on a year earlier, when the bank made a $380m loss.
This was the result of setting aside billions of dollars to settle charges relating to the sale of mortgage-related investment products.
Separately, rival Citigroup posted profits of $3.44bn and said it would exit consumer banking in 11 markets.
JP Morgan and Citigroup are the first major US banks to report third-quarter results.
Other big US banks will post their results later this week.
The JP Morgan results were due to be published at 08:30 local time (13:30 BST), but were posted early.
They showed total revenue for the quarter of $25.2bn, up 5% on a year earlier. Revenue at the investment banking business fell by $600m, with profits down by 34%.
Revenue at the asset management arm grew by $250m to $3bn, with profits up 20%.
"Our businesses continue to perform well," said chief executive Jamie Dimon.
"While challenges remain in the global economic recovery, the US economy is an exception, showing signs of steady improvement.
"Corporate America is in good shape, with strong balance sheets, and employment trends continue to be positive."
Citigroup saw its profits rise 7% to $3.44bn on revenues of $19.6bn.
The bank also said it would accelerate plans to focus on markets "where it has the greatest scale and growth potential".
As a result, it said it would be exiting consumer banking in 11 markets - Costa Rica, Czech Republic, Egypt, El Salvador, Guam, Guatemala, Hungary, Japan, Nicaragua, Panama and Peru, as well as its consumer finance business in South Korea.
"Our consumer bank and institutional business each had solid performance during the quarter and generated stronger revenues both sequentially and year-on-year," said the bank's chief executive Michael Corbat.
"I am committed to simplifying our company and allocating our finite resources to where we can generate the best returns for our shareholders."
Wells Fargo profit rises
Meanwhile, smaller rival Wells Fargo reported a $5.7bn profit for the third quarter, up 1.7% on the same period last year.
Revenues rose 3.4% to $21.2bn.
Chairman and chief executive John Stumpf said the results "demonstrated strength".
"We continue to see signs of a steadily improving economy, and I remain optimistic about the opportunities ahead for Wells Fargo," he added.
