Negotiations between the United States Justice Department and JPMorgan have hit a stumbling block that has put the talks at risk.
A week and a half ago, JPMorgan tentatively agreed to pay US$13 billion ($16 billion) to settle allegations surrounding the low quality of mortgage-backed securities it sold in the run-up to the 2008 financial crisis.
One of the unresolved issues in the talks is that JPMorgan says it should be able to seek money from a receivership involving Washington Mutual, a failed savings and loan association that JPMorgan bought in 2008, said an unnamed source.
The receivership is overseen by Federal Deposit Insurance (FDIC), the independent agency created by Congress to maintain stability in the banking system. The FDIC's position is that JPMorgan is responsible for any liabilities regarding the acquisition of Washington Mutual.
The unnamed source says the two sides also disagree over whether the bank can face criminal charges. The tentative US$13 billion deal only covers civil issues.
