From a regulatory perspective, I think it is unlikely that decentralised markets will be suitable in all instances or that decentralisation will guarantee the achievement of public policy objectives such as consumer protection, financial stability as well as safety and soundness, which fall within the mandates of central banks and regulators.
The role of central banks, regulators and policymakers should, however, evolve with financial markets to ensure that we continue to fulfil our mandates in future financial markets.
