Jamie Dimon, CEO of JPMorgan Chase, said on Monday that the continuously rising U.S. debt is a "big problem" and could bring "difficult times" to the bond market, leading to widening spreads. This comment is consistent with his earlier warning of potential market turmoil due to increased government spending in the United States. "If people think the dollar is no longer a reliable choice, you may see credit spreads widen; that will be a pretty big problem," Dimon said. "This will affect borrowers, including small businesses, small business loans, high-yield debt, leveraged loans, and real estate loans. Therefore, we should be concerned about the volatility of the bond market."
