There are two main factors that has Dimon worried: First, the Federal Reserve has signaled it will reverse its emergency bond-buying programs and shrink its balance sheet. The so-called quantitative tightening, or QT, is scheduled to begin this month and will ramp up to $95 billion a month in reduced bond holdings.

“We’ve never had QT like this, so you’re looking at something you could be writing history books on for 50 years,” Dimon said. Several aspects of quantitative easing programs “backfired,” including negative rates, which he called a “huge mistake.”…

The other large factor worrying Dimon is the Ukraine war and its impact on commodities, including food and fuel. Oil “almost has to go up in price” because of disruptions caused by the worst European conflict since World War II, potentially hitting $150 or $175 a barrel, Dimon said.

“Wars go bad, [they] go south in unintended consequences,” Dimon said. “We’re not taking the proper actions to protect Europe from what’s going to happen to oil in the short run.”
