Does the financial system need bank deposits, or could it do as well with other liabilities or even representations of liabilities? This question signals, Mr. McKernan said, a policy transformation warranting attention in the most senior quarters, not just among “technocrats.” He’s right, and here’s why.
As the American Banker rightly pointed out last week, analysis here must carefully differentiate tokenized deposits from deposit tokens. Tokenized deposits are deposits, albeit with additional functionality.
