(Bloomberg) — JPMorgan Chase & Co. Chairman Jamie Dimon said the unwinding of central bank bond-buying programs is an unprecedented challenge that may be more disruptive than people think.
"We've never have had QE like this before, we've never had unwinding like this before," Dimon said at a conference in Paris Tuesday. "Obviously that should say something to you about the risk that might mean, because we've never lived with it before."
Central banks led by the U.S. Federal Reserve are preparing to reverse massive asset purchases made after the financial crisis as their economies recover and interest rates rise. The Fed alone has seen its bond portfolio swell to $4.5 trillion, an amount its want to reduce without roiling longer-term interest rates. Minutes of the Fed's June 13-14 meeting indicate policy makers want to begin the balance-sheet process this year.
"When that happens of size or substance, it could be a little more disruptive than people think," Dimon said. "We act like we know exactly how it's going to happen and we don't."
