According to online reports, JPMorgan Chase CEO Dimon warned that the bond market is "bound to crack" after the U.S. government and the Federal Reserve's "massive excessive" spending and quantitative easing. "I just don't know if there will be a crisis in six months or six years, and I hope we can change the trajectory of debt and the ability of market makers to make markets," Dimon said. "Unfortunately, we may need it to wake us up." Dimon has repeatedly said in recent years that he is concerned about global deficit spending. Asked on Friday whether the so-called Bond Vigilantes were making a comeback, he said: "Yes."
