While speaking at an event by the office of Financial Research Federal Reserve Vice Chairman for Supervision Randal Quarles talk about the issues digital currencies could pose to the markets; the current level of use doesn’t pose a risk but as the scale of usage increases so does the potential potential problem; Quarles said, “if the central asset in a payment system cannot be predictably redeemed for the U.S. dollar at a stable exchange rate in times of adversity, the resulting price risk and potential liquidity and credit risk pose a large challenge for the system.”; he also talked about the the benefits of blockchain technology and if the central bank would issue their own digital currency.
