Veteran bank executives are meeting with senior lawmakers and federal officials as the government comes within two weeks of a potential debt default.

The debt ceiling, a statute established by Congress that prevents the government from spending beyond a predetermined national debt limit of $31.4 trillion, exceeded the threshold earlier this year. Treasury Secretary Janet Yellen said in a letter that her agency expects to default on obligations as early as the first day of June unless the debt limit is amended.

Senate Majority Leader Chuck Schumer (D-NY) hosted a meeting with JPMorgan Chase CEO Jamie Dimon and Citigroup CEO Jane Fraser on Wednesday morning, according to a report from Bloomberg. Dimon informed the outlet that his financial institution created a “war room” that will monitor contingencies should lawmakers fail to make a deal to increase the debt limit.
