JP Morgan Chase's third-quarter profit rose 23%, but revenue and loan balances continue to show just how much the nation's banks struggle to find a firm footing after the financial crisis.

The nation's second largest bank by assets reported $300bn in new and renewed credit and capital raises in the quarter, and it said consumers spent more on their credit cards. But consumers and businesses continue to pay off loans faster than the bank makes new ones, and Wall Street's wobble over the summer reduced revenue and profits from the securities business.
