No doubt, technology enables market participants to operate in a fraction of seconds, but the same technology is available for regulators too, to collect information, monitor and analyse in an equally fast manner.

In debates relating to public policy on public utilities, issues of regulation, competition and ownership were considered in an integrated manner. That used to apply to the finance industry also, before deregulation and privatisation became the preferred policies.
