According to the financial services provider, the figure, which was equivalent to $1.09 per share, represented an increase on the $2.7 billion seen in the same period of 2009.
The net income included $1.5 billion taken from JPMorganâs loan loss reserves, while the figure was also âpartially offset by a charge of $550 million for the UK bonus taxâ, Jamie Dimon, chairman and chief executive officer at the bank explained.
Commenting on the overall performance of the bank, Mr Dimon said: âMany challenges and uncertainties remain which may result in unintended consequences for our clients, the markets and our businesses.
âWith a need for global regulatory coordination and hundreds of rules to be written, increased focus is critical in order to implement these reforms in a way that protects consumers and the competitiveness of the US financial system, while ensuring the flow of safe and sound credit.â
He added that although the number of customers defaulting on loans and making late payments fell, âthey remain at extremely high levelsâ.
Further figures from JPMorgan revealed its tier one common ration was recorded at 9.6 per cent by the end of the quarter.
The bank also provided clients with almost $700 billion worth of capital in the form of loans across the first half of 2010.
