Dimon said an actual default by the government would be "potentially catastrophic."

"We cannot have a default. You can play fire right up to close over here, but please do not have a default. That would wreck permanent damage on America and its future. And it could destroy its future."

President Joe Biden, in his address to a joint session of Congress on Tuesday (February 7), urged Republicans to raise the $31.4 trillion debt ceiling, which must be lifted in the coming months to avoid a default.
