The nation's second-largest bank reported strong growth in net interest income, revenue and profits. But analysts continued to express concern about unrealized losses, which swelled to $131.6 billion.

Executives of the $405 billion-asset bank say that they have completed 40% of a cost-cutting strategy begun earlier this year.

Goldman Sachs said that its partnerships with Apple and General Motors are hard to exit in the short term. So the investment banking giant is concentrating on making the deals profitable, even as it acknowledges that they may not be a long-term fit.

Net income was $2.06 billion in the third quarter, down 33% from a year earlier, amid sluggish banking activity, real estate write-downs and questions about whether dealmaking will rebound.

The second-largest U.S. bank says net interest income, a key source of revenue for the bank, rose 4.5% to $14.4 billion in the third quarter.

The Westlake, Texas, firm said deposits fell 28% to $284.4 billion in the third quarter from the year prior, beating the $268.8 billion average estimate of analysts surveyed by Bloomberg.

The issuances may be driven by the companies' needs to meet their total loss-absorbing capacity requirements, which require banks to hold a certain amount of debt at the level of their holding companies that can be converted to equity in an emergency.

Net interest income rose sharply at Wells Fargo and especially JPMorgan Chase last quarter, thanks to lighter-than-expected deposit costs. But questions linger about how long both companies can keep a lid on those expenses and whether smaller competitors can do the same.

Jane Fraser defended Citigroup's recently announced organizational overhaul and specific performance targets, saying the plan is different from prior restructurings because it's designed to fundamentally change how the company operates.

JPMorgan Chase now tops Wells Fargo in third-party servicing, origination volume and on-balance-sheet home loans, according to company filings.
