JPMorgan CEO Jamie Dimon says bank is preparing 'war room' on debt ceiling

JPMorgan Chase & CO CEO Jamie Dimon said on Thursday bank staff are meeting weekly to discuss the potential implications for clients, contracts and markets of a potential U.S. default.

While he does not expect that potentially "catastrophic" outcome, it will likely convene daily "war room" to discuss a potential default as the U.S. government get closer to running out of cash to pay its obligations, he said.
